Estimated Loads and Yields of Suspended Solids and

Water-Quality Constituents in Kentucky Streams

By Angela S. Crain

Abstract

Loads and yields of suspended solids,

nutrients, major ions, trace elements, organic

carbon, fecal coliform, dissolved oxygen, and

alkalinity were estimated for 22 streams in

11 major river basins in Kentucky. Mean daily

discharge was estimated at ungaged stations or

stations with incomplete discharge records

using drainage-area ratio, regression analysis, or

a combination of the two techniques.

Streamflow was partitioned into total and base

flow and used to estimate loads and yields for

suspended solids and water-quality constituents

by use of the ESTIMATOR and FLUX

computer programs. The relative magnitude of

constituent transport to streams from groundand surface-water sources was determined for

the 22 stations. Nutrient and suspended solids

yields for drainage basins with relatively

homogenous land use were used to estimate the

total-flow and base-flow yields of nutrient and

suspended solids for forested, agricultural, and

urban land.

Yields of nutrients—nitrite plus nitrate,

ammonia plus organic nitrogen, and total

phosphorus—in forested drainage basins were

generally less than 1 ton per square mile per

year ((ton/mi2

)/yr) and were generally less than

2 (ton/mi2

)/yr in agricultural drainage basins.

The smallest total-flow yields for nitrogen

(nitrite plus nitrate) was estimated at Levisa

Fork at Paintsville in which 95 percent of the

land is forested. This site also had one of the

smallest total-flow yields for ammonia plus

organic nitrogen. In general, nutrient yields

from forested lands were lower than those from

urban and agricultural land.

Some of the largest estimated total-flow

yields of nutrients among agricultural basins

were for streams in the Licking River Basin, the

North Fork Licking River near Milford, and the

South Fork Licking River at Cynthiana.

Agricultural land constitutes greater than

75 percent of the drainage area in these two

basins. Possible sources of nutrients discharging

into the Licking River are farm and residential

fertilizers. Estimated base-flow yields of

suspended solids and nutrients at several basins

in the larger Green River and Lower

Cumberland River Basins were about half of

their estimated total-flow yields. The karst

terrain in these basins makes the ground water

highly susceptible to contamination, especially

if a confining unit is thin or absent.

INTRODUCTION

According to the Kentucky Environmental

Quality Commission (1992), nonpoint-source runoff

from agriculture, logging, mining, and urban

development results in about 62 percent of the

water-pollution problems in Kentucky. This runoff

results in increased levels of suspended solids,

nutrients, and trace elements in streams, which can

have detrimental effects on the environment.

Therefore, reductions of these chemical-constituent

or contaminant loads are vital to the health of the

aquatic ecosystem.

In July 1996, the U.S. Geological Survey

(USGS), in cooperation with the Kentucky Natural

Resources and Environmental Protection
2 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

Cabinet—Division of Water, began a study to

estimate the loads and yields of suspended solids

and selected water-quality constituents for

44 Kentucky streamflow stations for total flow and

periods of base flow. These streams constitute the

Kentucky Ambient Surface-Water Monitoring

Network. Estimated loads and yields for 20 of these

stations were published in 1998 (Garcia and Crain,

1998) (phase I); results for these stations are

included in the appendixes of this report. In

continuing this study (phase II), the loads and yields

were estimated for 22 of the remaining 24 stations.

No loads or yields were estimated for two stations

(Tradewater River at Olney and Mayfield Creek

near Blandville) because of problems in estimating

discharge as a result of backwater from the Ohio

and Mississippi Rivers.

Both point sources and nonpoint sources of

chemical constituents, or contaminants, contribute

to the total load of a stream. Generally, the inflow of

point-source contaminants to streams remains

relatively constant, and can be considered a

component of stream-water quality at base flow. By

contrast, nonpoint-source contaminants are

transported to streams primarily during storm runoff

periods. Thus, information about the relative

magnitude of suspended solids and water-quality

constituent loads in streams at base flow, which

largely originates from ground-water sources, and at

total surface-water flow (storm-water runoff) will be

helpful to those responsible for the planning and

management of nonpoint-source pollution control

programs.

Purpose and Scope

This report describes the methods used to

evaluate streamflow, suspended solids, and waterquality information for 44 stream stations in

Kentucky (fig. 1). These stations (table 1) were

selected from the Kentucky Ambient Surface-Water

Monitoring Network to determine the relative

magnitude of the loads and yields of suspended

solids and selected water-quality constituents

(table 2) transported in surface and ground water.

Constituents for which estimated loads and yields

are reported include suspended solids, nutrients,

major ions, trace elements, organic carbon, and

fecal coliform. It is not within the scope of this

report to provide detailed analyses of the factors that

affect the constituent concentrations measured in

each of the selected streams.

Selected Study Stations

The 24 stations included in phase II of this

study are located in 11 major drainage basins

(fig. 2). Stations from phase I also are located in

these drainage basins (appendix 1).

8 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

Because the morphology of each station is

different, geographic location can affect the waterquality at that station. Of the 24 stations in phase II,

7 have more than 60 percent of their drainage area

within the Eastern Coalfield Region (fig. 3), where

water-quality is affected by the effects of coal

mining (Leist and others, 1981; Quinones and

others, 1981). Four stations have more than

50 percent of their drainage area within the Inner

and Outer Bluegrass Regions, where water quality

is affected by activities associated with urbanization

and agriculture (table 3). Six stations have greater

than 60 percent of their drainage area within the

Mississippian Plateaus Region, which is

characterized by karst topography. The waterquality in this region is primarily affected by

agricultural activities. The locations of the selected

stations from phase I in the different physiographic

regions can be found in appendix 2.

Land use also affects the presence and

concentrations of constituents in water and is

important in assessing loads and yields. Land use

was characterized into six categories: urban,

agriculture, forest, water, wetland, and barren

(table 3, fig. 4, and appendix 3). Forest was the

largest represented category in the Eastern

Coalfield, with a mean of 89 percent. Agriculture

was the largest represented category for the other

physiographic regions in Kentucky, with a mean of

52 percent. Water (major rivers and reservoirs) was

the least represented category across Kentucky, with

a mean of less than 1 percent.

METHODS FOR ESTIMATING

LOADS AND YIELDS OF

SUSPENDED SOLIDS AND

SELECTED WATER-QUALITY

CONSTITUENTS

The load of a water-quality constituent in a

stream—the weight of material transported during a

specific time period—is determined by multiplying

the concentration of the constituent by the stream

discharge; the yield is determined by dividing the

load by the drainage area of the basin. Waterquality, suspended solids, and stream-discharge data

were used to estimate the annual loads and yields

for streams for total flow and base flow. Specific

methods used in this study are described in the

following sections.

Selection of Stations and

Assembly of Data Sets

Stations were selected from the Kentucky

Ambient Surface-Water Monitoring Network,

which were originally established on the basis of

the U.S. Environmental Protection Agency

(USEPA) criteria for sampling major rivers and

significant tributaries at the mouths of major

streams (U.S. Environmental Protection Agency,

1977). Suspended solids and water-quality data

were collected by the Kentucky Division of Water

(KDOW) and analyzed by the Kentucky Division of

Environmental Services. Streamflow data were

collected by USGS Kentucky District personnel.

Suspended solids and water-quality data for the

period October 1979–September 1997 were

retrieved from the USEPA Storage and Retrieval

(STORET) data base. The list of constituents is

presented in table 2. The STORET data were

reformatted and entered into the USGS National

Information System (NWIS) data base to facilitate

formats required by the ESTIMATOR (Baier and

others, 1992) and FLUX (Walker, 1987) computer

programs to estimate total and base-flow load

estimates.

Daily discharge records matching the period

of suspended solids and water-quality data were

retrieved from NWIS. Daily base flow was

determined from the daily discharge records

through use of a stream hydrograph partitioning

program developed by Rutledge (1998). No

additional daily discharge record manipulation was

required for estimating total loads by use of the

ESTIMATOR computer program; however, the

partitioned daily discharge records were

reformatted for use in determining loads by use of

the FLUX computer program.

State boundary and hydrologic coverages

were from USGS 1:100,000-scale digital line

graphs (U.S. Geological Survey, unpub. digital data,

1983). Drainage-basin boundaries were from

1:24,000-scale 14-digit hydrologic unit boundary

coverages (Forbes and others, 1997; Nelson and

others, 1997a-e). The coverage for site location was

generated in ARC/INFO from latitude and longitude

coordinates.

The physiographic regions were modified

from a coverage created from a hand-drawn map by

Lobeck (1930). The procedure for generating the

coverages and calculating the physiographic-region

percentages in each drainage basin was similar to

that used for land use.

Land-use coverage was obtained from USGS

1:250,000-scale digital land-use and land-cover data

(U.S. Geological Survey, unpub. digital data, 1986).

Land-use coverages for each drainage basin were

created in ARC/INFO. Land-use percentages were

determined by data generated by ARC/INFO to

obtain the total percentage for each land-use

category.

Daily Discharge Synthesis

Daily mean discharge was estimated for three

stations. Daily mean discharge at an ungaged station

or a station with incomplete discharge records

(missing data) was estimated using drainage-area

ratio, multiple-regression analysis, or a combination

of the two techniques. For stations on the same

stream or in proximity to one another, a drainagearea ratio was used for determining daily mean

discharge. Commonly, the equation for drainagearea ratio is expressed as

(1)

where

Q is the daily mean discharge at a given

station,

DA is the drainage area for a given station,

u is the station where discharge is

unknown,

b is the station downstream, and

a is the station upstream.

Daily mean discharge for Cumberland River

near Burkesville was determined by directly

applying a ratio to the daily mean discharge from

Cumberland River at Rowena. The drainage-area

ratio between these two stations was 1.04.

Multiple-regression analysis was used to

determine daily mean discharge for Horse Lick

Creek near Lamero using the available daily mean

discharge at Buck Creek near Shopville. The

multiple-regression equation with logarithmic

transformation was:

(2)

where

ln is the natural logarithm function,

Q is the daily mean discharge at a given

station,

HLC is the streamflow station at Horse Lick

Creek near Lamero, and

BC is the streamflow station at Buck Creek at

Shopville.

The adjusted R2

 was 0.93 and the standard error of

the estimate was equal to 0.284 for this equation.

Kentucky River near Trapp required synthesis

of daily mean discharge. Daily mean discharge

records from Kentucky River at Lock 10 and Red

River at Clay City were used to synthesize the daily

mean discharge at the Trapp station. The equation

used by the KDOW was applied to estimate the

discharge at Trapp (Giles Miller, Kentucky Division

of Water, written commun., 1996). The equation

used by the KDOW is:

, (3)

where

Q is the daily mean discharge at a given

station,

Lock 10, and

City.

14 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

Hydrograph Separation

Nonpoint-source contaminants are generally

transported to receiving waters during storm runoff

periods (U.S. Environmental Protection Agency,

1996). Thus, the partitioning of constituent loading

into surface-runoff and base-flow components can

provide a means of measuring the effects nonpointsource contaminants have on water quality and

suspended solids. The partitioning of the base-flow

data began with the retrieval of daily-mean

discharge records to match the period of waterquality data. A computerized method was used to

estimate base flow from the long-term dailydischarge record (Rutledge, 1998). Missing record

was synthesized as needed by use of the techniques

described previously.

Rutledge’s (1998) program for determining

periods of base streamflows is based on antecedent

streamflow recessions, whereas antecedent rainfall

conditions are specified in other methods. A onedimensional array filled with daily mean streamflow

record is evaluated for days fitting an antecedent

recession requirement. On these days, base flow is

equal to streamflow if it is not followed by a daily

decline greater than 0.1 log cycle. The partitioning

program continues searching the array and

determines base flow for the remaining days by

linear interpolation. Base flows that exceed

antecedent streamflow can be generated, but these

flows are corrected during the last step of the

program.

Rutledge’s (1998) program executes three

times, once in which the time base of surface-runoff

is the largest integer less than the result of the

following empirical equation (Linsley and others,

1982):

, (4)

where

N is number of days after the peak, and

A is drainage area in mi2

.

A second-order polynomial expression is

generated for base flow using the results in

equation 2. Results are calculated with equation 4

based on the polynomial expression (Rutledge,

1998).

After the base flows were determined, the

values were entered into the NWIS data base. An

example of a hydrograph separation for Kinniconick

Creek near Tannery (03237250) is presented in

figure 5.

Selection of Base-Flow Samples

A component of the study objective was to

estimate the contribution of constituent transport

during base flow. To accomplish this objective,

suspended solids and water-quality records meeting

a predetermined base-flow criterion were selected

for specific days. The partitioned discharge data set

provided the means for selected suspended solids

and water-quality records determined to represent

base-flow samples. Analytical results for those

water samples were retained in the data set if base

flow for the day in question was less than 0.9 times

the total flow for the same day. The matching

records were retrieved for use in estimating loads

and yields for the base-flow component.

Estimates of Loads

The computer programs, ESTIMATOR and

FLUX (Baier and others, 1992; Walker, 1987), were

used to estimate loads on the basis of mean daily

discharge and water-quality data. Yields were

determined by dividing the estimated load by the

drainage area of the basin.

ESTIMATOR is a statistical-regression model

that is used to estimate loads on days that are not

sampled. This model includes an adjusted

maximum-likelihood estimator (AMLE), which

allows the use of data sets containing censored

values (Cohn, 1988, 1995). The AMLE provides a

means to measure uncertainty in estimated loads.

ESTIMATOR has a maximum of seven

independent parameters: an intercept, two discharge

parameters, and four time parameters. Independent

parameters in the model are both linear and

nonlinear. A quadratic discharge parameter is

included to account for the possibility of a nonlinear

log relation between concentration and discharge.

years 1992–97.

Similarly, linear and quadratic time parameters are

included to account for possible nonlinear trends in

the long-term average concentration of a

constituent. Cyclical variations in concentration

often occur on a seasonal basis; thus, trigonometric

functions are included to account for possible

seasonal effects. The “centering” parameters—

and —are defined to reduce covariance among

the independent parameters and enhance estimate

precision. In the ESTIMATOR computer program,

daily streamflow data and water-quality data were

used to calibrate a multiple-regression equation of

the form:

where

ln is the natural logarithm function;

β0 is a constant;

β1 – β6 are the beta coefficients of the

explanatory variables;

C is the measured concentration (mg/L);

Q is the mean daily discharge on the day

16 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

For each water-quality constituent, the

ESTIMATOR computer program provides an output

file with regression diagnostics, diagnostics plots,

and computed loads for the time period selected by

the user. Estimated monthly and annual mean daily

loads, in kilograms per day, are calculated by the

program for each calendar year and water year. The

standard error and the standard error of prediction

for each mean daily load estimate also are

calculated by the program. Estimated mean annual

loads for each station were determined by the sum

of the daily loads for all years and then dividing that

sum by the number of years of available data.

Estimated mean annual loads were converted to

units of ton/yr for data presentations in this report.

The computer program FLUX (Walker, 1987)

was used to estimate loads when the regression

diagnostic coefficient of determination (R2) from

the ESTIMATOR computer program was less than

or equal to 50 percent. One of two methods

(International Joint Commission or regression-1)

available in FLUX was used to estimate the load for

each constituent at each station that did not meet the

R2

 criterion as described above. The International

Joint Commission method applies a flow-weighted

mean concentration to the mean flow with a bias

adjustment factor for situations in which

concentration varies with flow. The regression-1

method regresses the logarithm of concentration

against the logarithm of mean daily discharge. The

method with the lowest estimated coefficient of

variation was used to obtain estimates of mean

annual loads. The constituents by site for total and

base flow that had loads run by use of the FLUX

computer program are listed in appendix 4 (phase II

stations) and appendix 5 (phase I stations).

A comparison of the same data set results

from the ESTIMATOR and FLUX computer

programs for selected sites is presented in table 4. In

general, the total- and base-flow loads estimated by

the FLUX program were larger than the loads

estimated by use of the ESTIMATOR program.

A statistical summary of the aggregated total

yields for all constituents is presented in table 5 for

the phase II stations. Aggregated total yields for

phase I are summarized in appendix 6. Estimates of

mean annual total-flow and base-flow loads and

yields of suspended solids and selected waterquality constituents are presented in table 6 for

phase II stations. The mean annual total-flow and

base-flow loads and yields from phase I are

presented in appendix 7. The discussions of

constituent loads and yields that follow are all

referenced to table 6 unless otherwise noted.

Descriptive statistics for selected ambient

monitoring stations in Kentucky are presented in

table 7 for phase II stations. Phase I descriptive

statistics are presented in appendix 8. Where

5 percent of the observations reported were at

concentrations less than the detection limit,

summary statistics were generated from a

combination of the observations above the detection

limit with below-limit values extrapolated on the

basis of a log-probability regression procedure

(Helsel and Cohn, 1988; Helsel, 1990). The

estimated distribution parameters (percentiles) are

presented in table 7 (phase II stations) and

appendix 7 (phase I stations).

20 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

Suspended Solids

Suspended solids is that part of a sample

retained on a glass-fiber filter after the water from

the sample is drawn through the filter. The filter is

then dried and weighed to determine the suspended

solid concentration. Suspended solids may also be

referred to as “nonfilterable residue” at 105 ̊C. The

effectiveness of suspended solids in sorbing and

transporting some metals, pesticides, and other

organic compounds can be detrimental to a stream’s

ecology (Kuwabara and others, 1989; Domagalski

and Kuivila, 1993; Flegal and others, 1996). In

addition, high concentrations of suspended solids

are aesthetically unsatisfactory and can adversely

affect the biological community within the streams

(Luoma and others, 1985; Brown and Luoma, 1995;

Luoma, 1996).

Samples analyzed for suspended solids were

collected at 24 sites. Concentrations ranged from

0.5 mg/L at Cumberland River at Burkesville to

2,640 mg/L at Rolling Fork near Lebanon Junction

(table 7). Loads were determined for 22 of the

24 sites. Mean annual total-flow loads ranged from

850 ton/yr at Horse Lick Creek near Lamero to

771,000 ton/yr at Green River at Paradise (table 6).

Mean annual base-flow loads ranged from 10 ton/yr

at Horse Lick Creek near Lamero to 345,000 ton/yr

at Green River at Paradise (table 6). Mean annual

total-flow yields ranged from 13.8 ton/mi2

 at Horse

Lick Creek near Lamero to 1,980 ton/mi2 at Tygarts

Creek near Load (table 6). Mean annual base-flow

yields ranged from 0.16 ton/mi2

 at Horse Lick

Creek near Lamero to 144 ton/mi2

 at Little River

near Cadiz (table 6). The mean and median

aggregate total-flow yields were 272 and

125 ton/mi2, respectively (table 5).

Fecal-Coliform Bacteria

The presence of fecal-coliform bacteria in

surface water indicates fecal contamination from

warm-blooded animals and (or) humans and is an

indicator that a potential health risk exists for

individuals exposed to the water (Christensen and

Pope, 1997). Kentucky’s water-quality criteria for

fecal-coliform bacteria densities are: 2,000 colonies

per 100 milliliters of water (col/100 mL) for

domestic water supply (pre-treatment),

1,000 col/100 mL for boating and fishing, and

200 col/100 mL for swimming (Kentucky Natural

Resources and Environmental Protection Cabinet,

1990).

Samples analyzed for fecal coliform were

collected at 24 sites. Concentrations ranged from

1.0 col/100 mL at several sites to

99,000 col/100 mL at Tug Fork at Kermit, West

Virginia (table 7). Loads were determined for 22 of

the 24 sites. Mean annual total-flow loads ranged

from 4.47 col/100 mL at Pond River near

Madisonville to 1,203 col/100 mL at Tug Fork at

Kermit, West Virginia (table 6). Mean annual baseflow loads ranged from 0.01* 1015 colonies per

100 milliliters (1015 col/100 mL) at Horse Lick

Creek near Lamero to 990* 1015 col/100 mL at Tug

Fork at Kermit, West Virginia (table 6). Mean

annual total-flow yields ranged from

0.01* 1015 colonies per square mile (1015 col/mi2)

at Pond River near Madisonville to 5* 1015 col/mi2

at North Fork Licking River at Milford (table 6).

Mean annual base-flow yields ranged from

0.01* 1015 colonies per 100 milliliters per square

mile ((1015 col/100 mL)/mi2) at several sites to

0.8* 1015 col/mi2 at Tug Fork at Kermit, West

Virginia (table 6). The mean and median aggregate

total-flow yields were 0.4* and 0.2* 1015 col/mi2

,

respectively (table 5).

Major Ions

Water contains varying concentrations of

dissolved ions. The major positively charged ions

(cations) occurring in natural waters are calcium,

magnesium, potassium, and sodium (Peters and

others, 1998). Three dominant negatively charged

ions (anions) are sulfate, chloride, and bicarbonate

(Peters and others, 1998).

Calcium and Magnesium

Calcium and magnesium are essential

elements for plant and animal life (Britannica.com

Inc., 2000). Calcium is the most common cation

occurring in natural stream water. Both calcium and

magnesium may be considered as having similar
LOADS AND YIELDS OF SUSPENDED SOLIDS AND SELECTED WATER-QUALITY CONSTITUENTS 21

effects in some aspects of water chemistry such as

their contributions to water hardness (Hem, 1989,

p. 93-97).

Samples analyzed for calcium were collected

at 24 sites. Concentrations ranged from 0.1 mg/L at

Horse Lick Creek near Lamero to 443 mg/L at Pond

River near Madisonville (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 8.2 ton/yr at Bayou de

Chien near Clinton to 3,607 ton/yr at Green River at

Paradise (table 6). Mean annual base-flow loads

ranged from 1 ton/yr at Horse Lick Creek near

Lamero to 2,473 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields ranged from

10 ton/mi2

 at Kinniconick Creek near Tannery to

92 ton/mi2 at South Fork Licking River at

Cynthiana (table 6). Mean annual base-flow yields

ranged from 2 ton/mi2

 at Horse Lick Creek near

Lamero to 41 ton/mi2 at Little River near Cadiz

(table 6). The mean and median aggregate total-flow

yields were 42 and 39 ton/mi2

, respectively

(table 5).

Samples analyzed for magnesium were

collected at 24 sites. Concentrations ranged from

1 mg/L at Mayfield Creek near Blandville to

185 mg/L at Pond River near Madisonville (table 7).

Loads were determined for 22 of the 24 sites. Mean

annual total-flow loads ranged from 3 ton/yr at

Bayou de Chien near Clinton to

650 ton/yr at Green River at Paradise (table 6).

Mean annual base-flow loads ranged from

0.3 ton/yr at Horse Lick Creek near Lamero to

436.6 ton/yr at Green River at Paradise (table 6).

Mean annual total-flow yields ranged from

3.8 ton/mi2

 at Bayou de Chien near Clinton to

21.9 ton/mi2 at Pond Creek near Louisville

(table 6). Mean annual base-flow yields ranged from

0.5 ton/mi2

 at Horse Lick Creek near Lamero to

10.5 ton/mi2

 at Cumberland River at Pineville

(table 6). Both the mean and median aggregate

total-flow yields were 10 ton/mi2 (table 5).

Potassium and Sodium

Potassium and sodium have many similar

chemical properties and are both from the alkalimetal group of the periodic table. Both elements are

extremely reactive and therefore do not occur freely

in nature (Britannica.com Inc., 2000).

Samples analyzed for potassium were

collected at 24 sites. Concentrations ranged from

0.6 mg/L at Horse Lick Creek near Lamero to

94.3 mg/L at Horse Lick Creek near Lamero

(table 7). Loads were determined for 22 of the

 at Pond Creek near Louisville (table 6).

Mean annual base-flow yields ranged from

0.1 ton/mi2

 at Horse Lick Creek near Lamero to

2.3 ton/mi2

 at Little River near Cadiz (table 6). The

near Lamero to 22 ton/mi2

 at Tug Fork at Kermit,

West Virginia (table 6). The mean and median

aggregate total-flow yields were 9 and 6 ton/mi2

,

respectively (table 5).

Chloride

Chloride is present in all natural waters.

Potential sources of chloride are from point sources

and from the use of salt for deicing highways

(Caudill and others, 2000). Public Drinking Water

Standards require chloride levels not to exceed

250 mg/L. Criteria for protection of aquatic life

require levels of less than 600 mg/L for chronic

(long-term) exposure and 1,200 mg/L for short-term

exposure (Caudill and others, 2000).
22 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

Samples analyzed for chloride were collected

at 24 sites. Concentrations ranged from 0.1 mg/L at

several sites to 141 mg/L at Horse Lick Creek near

Lamero (table 7). Loads were determined for 22 of

the 24 sites. Mean annual total-flow loads ranged

from 2 ton/yr at Horse Lick Creek near Lamero to

495 ton/yr at Green River at Paradise (table 6).

 at Horse Lick Creek near Lamero to

16 ton/mi2 at Pond Creek near Louisville (table 6).

The mean and median aggregate total-flow yields

were 9 and 7 ton/mi2, respectively (table 5).

Sulfate

Sulfur is an essential plant nutrient. The most

common form of sulfur in well-oxygenated water is

sulfate (Caudill and others, 2000). Sulfate can occur

naturally in stream water from the breakdown of

leaves in streams or water flowing through rock or

soil containing gypsum (Caudill and others, 2000).

Point sources (wastewater-treatment plants and pulp

mills) and nonpoint sources (agriculture and acidmine drainage) also can contribute sulfate to water

bodies. High concentrations of sulfates in water

bodies can result in decreased pH (Caudill and

others, 2000). This is because sulfates have the

ability to form strong acids.

Samples analyzed for sulfate were collected

at 24 sites. Concentrations ranged from 2 mg/L at

Bayou de Chien near Clinton to 1,900 mg/L at Pond

River near Madisonville (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 13 ton/yr at Horse Lick

Creek near Lamero to 3,505 ton/yr at Green River at

Paradise (table 6). Mean annual base-flow loads

ranged from 3 ton/yr at Horse Lick Creek near

Lamero to 2,262 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields ranged from

18 ton/mi2 at Bayou de Chien near Clinton to

355 ton/mi2 at North Fork Licking River at Milford

(table 6). Mean annual base-flow yields ranged from

4 ton/mi2

 at Bayou de Chien near Clinton to

72 ton/mi2 at Pond River near Madisonville (table 6).

The mean and median aggregate total-flow yields

were 69 and 45 ton/mi2

, respectively (table 5).

Alkalinity

The alkalinity of water may be defined as the

capacity for solutes in water to react with and

neutralize acid (Hem, 1989). Alkalinity is one of the

best measures of the sensitivity of a stream to acid

inputs (U.S. Environmental Protection Agency,

1999). The alkalinity of natural water is primarily

caused by dissolved bicarbonate and carbonate

(Hem, 1989), except for water with high pH or

unusual chemical composition.

Samples analyzed for total alkalinity were

collected at 24 sites. Concentrations ranged from

1.00 mg/L (milligrams per liter) at Pond River near

Madisonville to 548 mg/L at Tradewater River near

Olney (table 7). Loads were determined for 22 of

the 24 sites. Mean annual total-flow loads ranged

from 23.1 ton/yr (tons per year) at Bayou de Chien

near Clinton to 7,830 ton/yr at Green River at

Paradise (table 6). Mean annual base-flow loads

ranged from 3.96 ton/yr at Horse Lick Creek near

Lamero to 5,540 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields ranged from

16.4 ton/mi2 at Kinniconick Creek near Tannery to

212 ton/mi2 at South Fork Licking River at

Cynthiana (table 6). Mean annual base-flow yields

ranged from 6.42 ton/mi2 at Horse Lick Creek near

Lamero to 96.3 ton/mi2 at Little River near Cadiz

(table 6). The mean and median aggregate total-flow

yields were 95.4 and 90.2 ton/mi2, respectively

(table 5).

Nutrients and Organics

Nutrients are typically defined as nitrogen and

phosphorus species. Nitrogen and phosphorus are

important elements necessary for the growth of

plants and animals (Caudill and others, 2000).

Concentrations of nitrogen and phosphorus

compounds are highly dynamic because they may

be utilized, stored, transformed, and excreted

rapidly and repeatedly by various aquatic organisms

(Wetzel and Likens, 1979). Forms of nitrogen in

water include organic nitrogen, ammonia, nitrite,
LOADS AND YIELDS OF SUSPENDED SOLIDS AND SELECTED WATER-QUALITY CONSTITUENTS 23

and nitrate. Phosphorus occurs in a number of

inorganic and organic compounds in both

particulate and dissolved forms.

The USEPA drinking-water standard for

nitrite is 1 mg/L and for nitrate is 10 mg/L. The

Kentucky domestic water supply standard for nitrate

is 10 mg/L; however, Kentucky does not have a

nitrite standard. Both the USEPA and Kentucky do

not have a drinking-water standard for nitrite plus

nitrate.

Nitrogen

Nitrogen in streams can originate from

numerous point and nonpoint sources. The major

entry routes of nitrogen into streams are wastewatertreatment plants, septic tanks, feed lot discharges,

and fertilizers from agricultural and residential

areas.

Samples analyzed for nitrite plus nitrate were

collected at 24 sites. Concentrations ranged from

0.01 mg/L at several sites to 9.8 mg/L at Pond Creek

near Louisville (table 7). Loads were determined for

22 of the 24 sites. Mean annual total-flow loads

ranged from 0.2 ton/yr at Horse Lick Creek near

Lamero to 101 ton/yr at Green River at Paradise

(table 6). Mean annual base-flow loads ranged from

0.01 ton/yr at Horse Lick Creek near Lamero to

67 ton/yr at Green River at Paradise (table 6). Mean

annual total-flow yields ranged from 0.3 ton/mi2

 at

Pond River near Madisonville to 4.3 ton/mi2

 at

Little River near Cadiz (table 6). Mean annual baseflow yields ranged from 0.2 ton/mi2 at Horse Lick

Creek near Lamero to 2 ton/mi2 at Little River near

Cadiz (table 6). The mean and median aggregate

total-flow yields were 1 and 0.8 ton/mi2

,

respectively (table 5).

Samples analyzed for ammonia were

collected at 24 sites. Concentrations ranged from

0.01 mg/L at Little River near Cadiz to 28 mg/L at

Tradewater River at Olney (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 0.04 ton/yr at Horse Lick

Creek near Lamero to 4 ton/yr at Salt River at

Shepherdsville (table 6). Mean annual base-flow

loads ranged from less than 0.01 ton/yr at Horse

Lick Creek near Lamero to 2 ton/yr at Green River

at Paradise (table 6). Mean annual total-flow yields

ranged from 0.2 ton/mi2 at Levisa Fork at

Paintsville to 1 ton/mi2 at Pond Creek near

Louisville (table 6). Mean annual base-flow yields

(table 6). The mean and median aggregate total-flow

yields were 0.1 and 0.6 ton/mi2

, respectively

(table 5).

nitrogen were collected at 24 sites. Concentrations

ranged from 0.02 mg/L at Cumberland River at

Burkesville to 29 mg/L at Tradewater River at

Olney (table 7). Loads were determined for 22 of

the 24 sites. Mean annual total-flow loads ranged

from 0.3 ton/yr at Horse Lick Creek near Lamero to

62 ton/yr at Green River at Paradise (table 6). Mean

annual base-flow loads ranged from <0.01 ton/yr at

Horse Lick Creek near Lamero to 30 ton/yr at Green

River at Paradise (table 6). Mean annual total-flow

yields ranged from 0.2 ton/mi2

 at Levisa Fork at

Paintsville to 2 ton/mi2 at North Fork Licking River

at Milford (table 6). Mean annual base-flow yields

ranged from <0.01 ton/mi2 at Horse Lick Creek near

Lamero to 0.7 ton/mi2 at Pond Creek near

Louisville (table 6). The mean and median

aggregate total-flow yields were 1 and 0.6 ton/mi2

,

respectively (table 5).

Phosphorus

Phosphorus is a common element in igneous

and sedimentary rocks; other sources of phosphorus

include sewage effluent, detergents, and leachates

from septic tanks (Caudill and others, 2000). Of the

major nutrients, phosphorus is the most frequently

limiting nutrient to aquatic organisms (Wetzel and

Likens, 1979); however, no federal or state waterquality criteria have been established for

phosphorus species.

Samples analyzed for total phosphorus were

collected at 24 sites. Concentrations ranged from

0.003 mg/L at Cumberland River at Burkesville to

5 mg/L at Pond Creek near Louisville (table 7).

Loads were determined for 22 of the 24 sites. Mean

annual total-flow loads ranged from <0.01 ton/yr at

Horse Lick Creek near Lamero to 16 ton/yr at Salt

River at Shepherdsville (table 6). Mean annual baseflow loads ranged from <0.01 ton/yr at Horse Lick

Creek near Lamero to 1.3 ton/yr at Green River at

Paradise (table 6).
24 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

<0.01 ton/mi2

 at Horse Lick Creek near Lamero to

Mean annual base-flow yields ranged from

<0.01 ton/mi2

 at Horse Lick Creek near Lamero to

0.3 ton/mi2 at Pond Creek near Louisville (table 6).

The mean and median aggregate total-flow yields

were 0.4 and 0.1 ton/mi2

, respectively (table 5).

Organic Carbon

Total organic carbon enrichment of natural

waters is often a result of effluent from wastewatertreatment plants or effluent from industrial waste

(Caudill and others, 2000).

Samples analyzed for total organic carbon

were collected at 24 sites. Concentrations ranged

from 0.1 mg/L at Horse Lick Creek near Lamero

and Salt River at Shepherdsville to 98 mg/L at

Green River at Paradise (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 1 ton/yr at Horse Lick Creek

near Lamero to 482 ton/yr at Green River at

Paradise (table 6). Mean annual base-flow loads

ranged from 0.1 ton/yr at Horse Lick Creek near

Lamero to 185 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields ranged from

at Pond Creek near Louisville (table 6). Mean

annual base-flow yields ranged from 0.1 ton/mi2 at

Horse Lick Creek near Lamero to 4 ton/mi2 at Pond

Creek near Louisville (table 6). The mean and

median aggregate total-flow yields were 5.5 and

4.5 ton/mi2, respectively (table 5).

Major Metals and Trace Elements

The major problems associated with

excessive amounts of trace metals in the

environment are that metals are nondegradable, tend

to be persistent contaminants, and can potentially

accumulate in plants and animals (Haag and others,

1995). In addition, each metal has a specific

chemical form that can determine its solubility in

water, and consequently its ability to incorporate

into aquatic life (Hem, 1989).

Trace elements and metals are found

throughout the Earth in rocks and soils (Hem,

1989). The processes of weathering and erosion can

contribute low amounts of metals to streams and the

atmosphere; however, many metal pollutants are

primarily distributed in the air and water by the

combustion of fossil fuels and domestic and

industrial wastewater (Evaldi and others, 1993). The

major metals and trace elements analyzed were

aluminum, arsenic, barium, cadmium, chromium,

copper, iron, lead, manganese, mercury, and zinc.

Aluminum

Although aluminum is one of the most

abundant elements in the Earth’s crust, it rarely

occurs in high concentrations in waters at nearneutral pH (Hem, 1989, p. 73). However, the

exception is water bodies with a very low pH

(pH <4). Water bodies containing high

concentrations of aluminum can become toxic to

aquatic life (U.S. Environmental Protection Agency,

1999).

Samples analyzed for aluminum were

collected at 24 sites. Concentrations ranged from

0.5 μg/L at Cumberland River at Burkesville to

49,000 μg/L at Green River at Paradise (table 7).

Loads were determined for 22 of the 24 sites. Mean

annual total-flow loads ranged from 0.2 ton/yr at

Horse Lick Creek near Lamero to 243 ton/yr at

Green River at Paradise (table 6). Mean annual

base-flow loads ranged from <0.01 ton/yr at Horse

Lick Creek near Lamero to 80 ton/yr at Green River

at Paradise (table 6). Mean annual total-flow yields

ranged from 0.3 ton/mi2 at Cumberland River at

Burkesville and Horse Lick Creek near Lamero to

13 ton/mi2 at North Fork Licking River at Milford

(table 6). Mean annual base-flow yields ranged from

<0.01 ton/mi2

 at Horse Lick Creek near Lamero to

3.1 ton/mi2

 at Little River near Cadiz (table 6). The

mean and median aggregate total-flow yields were 4

and 3 ton/mi2

, respectively (table 5).
LOADS AND YIELDS OF SUSPENDED SOLIDS AND SELECTED WATER-QUALITY CONSTITUENTS 25

Arsenic

Arsenic is a nonmetallic element and in low

concentrations can be toxic to humans and other

organisms. Recognized as a toxic element for

centuries, arsenic today also is a human-health

concern because it can contribute to skin, bladder,

and other cancers (National Research Council,

1999). It occurs as a result of geological processes,

manufacturing, smelting, and agriculture

(U.S. Environmental Protection Agency, 1999). The

USEPA maximum contaminant level (MCL) for

arsenic in drinking water is 10 μg/L

(U.S. Environmental Protection Agency, 2001). In

this study, most of the measured total arsenic

concentrations were below the detection limit of

1.0 μg/L (table 7). The mean annual total-flow

yields for all stations were below 0.01 ton/mi2

.

Samples analyzed for arsenic were collected

at 24 sites. Concentrations ranged from 0.1 μg/L at

Tradewater River at Olney to 33 μg/L at Pond Creek

near Louisville (table 7). Loads were determined for

22 of the 24 sites. Mean annual total-flow loads

ranged from <0.01 ton/yr at several sites to

0.1 ton/yr at Cumberland River at Pineville

(table 6). Mean annual base-flow loads ranged from

<0.01 ton/yr at several sites to 0.01 ton/yr at Green

River at Paradise (table 6). Mean annual total-flow

yields were <0.01 ton/mi2 at all sites (table 6). Mean

annual base-flow yields were <0.01 ton/mi2

 at all

sites (table 6). The mean and median aggregate

total-flow yields were <0.01 and <0.01 ton/mi2

,

respectively (table 5).

Barium

Barium is an alkaline-earth metal that can be

found in igneous and carbonate sedimentary rocks

(U.S. Environmental Protection Agency, 1999).

Barium is present in low concentrations in natural

waters and in treated drinking water

(U.S. Environmental Protection Agency, 1999). The

USEPA MCL for barium in drinking water is

200 μg/L. Kentucky criterion for barium in

domestic water supplies is 1,000 μg/L.

Samples analyzed for barium were collected

at 24 sites. Concentrations ranged from 0.5 μg/L at

Cumberland River at Burkesville to 480 μg/L at

Tradewater River at Olney (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 0.02 ton/yr at Horse Lick

Creek near Lamero to 3.7 ton/yr at Green River at

Paradise (table 6). Mean annual base-flow loads

ranged from <0.01 ton/yr at Horse Lick Creek near

Lamero to 2.1 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields ranged from

0.02 ton/mi2

 at Pond River near Madisonville to

0.1 ton/mi2

 at North Fork Licking River at Milford

(table 6). Mean annual base-flow yields ranged from

<0.01 ton/mi2 at Horse Lick Creek near Lamero to

0.06 ton/mi2 at Little River near Cadiz (table 6). The

mean and median aggregate total-flow yields were

0.07 and 0.06 ton/mi2

, respectively (table 5).

Cadmium

Cadmium is a natural element that is found in

the Earth’s crust (U.S. Environmental Protection

Agency, 1999). It is usually found as a mineral

combined with other elements such as oxygen,

chlorine, or sulfur (Hem, 1989, p. 142). Cadmium is

a widely distributed in the environment at low

concentrations; however, high concentrations of

cadmium are usually attributed to contamination

from mining or industrial waste

(U.S. Environmental Protection Agency, 1999).

Cadmium can bioaccumulate in plant and animal

tissue and is considered a potential carcinogen

(U.S. Environmental Protection Agency, 1999). The

USEPA drinking-water standard for cadmium is

5 μg/L. The standard of cadmium for Kentucky

domestic water supply is <100 μg/L. This criterion

established for cadmium was not exceeded by any

of the 24 water-quality stations in this study.

Samples analyzed for cadmium were

collected at 24 sites. Concentrations ranged from

0.5 μg/L at Horse Lick Creek near Lamero to

82 μg/L at Tradewater River at Olney (table 7).

Loads were determined for 22 of the 24 sites. Mean

annual total-flow loads ranged from <0.01 ton/yr at

several sites to 0.1 ton/yr at Cumberland River at

Burkesville (table 6). Mean annual base-flow loads

ranged from <0.01 ton/yr at Horse Lick Creek near

Lamero to 2.1 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields were

<0.01 ton/mi2 at all sites (table 6). Mean annual

base-flow yields were <0.01 ton/mi2 at all sites

(table 6). The mean and median aggregate total-flow

yields were <0.01 and <0.01 ton/mi2, respectively

(table 5).
26 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

Chromium

Chromium is ubiquitous in the environment,

occurring naturally in the atmosphere, water, and

rocks (Hem, 1989, p. 138). It is used in metal

plating, steel manufacturing, photography, and in

the manufacturing of paints, ceramics, and

explosives (U.S. Environmental Protection Agency,

1999). Acute toxicity can result from high exposure

to certain forms of chromium, and there is high

potential for accumulation in aquatic life

(U.S. Environmental Protection Agency, 1999).

Samples analyzed for chromium were

collected at 24 sites. Concentrations ranged from

0.5 μg/L at Cumberland River at Burkesville to

121 μg/L at Tygarts Creek near Load (table 7).

Loads were determined for 22 of the 24 sites. Mean

annual total-flow loads ranged from <0.01 ton/yr at

several sites to 3 ton/yr at Salt River at

Shepherdsville (table 6). Mean annual base-flow

loads ranged from <0.01 ton/yr at several sites to

0.1 ton/yr at Green River at Paradise (table 6). Mean

annual total-flow yields ranged from <0.01 ton/mi2

at 14 sites to 0.01 ton/mi2 at 8 sites (table 6). Mean

annual base-flow yields were <0.01 ton/mi2

 at all

sites (table 6). The mean and median aggregate

total-flow yields were <0.01 and <0.01 ton/mi2

,

respectively (table 5).

Copper

Copper is an essential element for plant

photosynthesis and for animal metabolism. The

toxicity of copper to aquatic organisms is dependent

on the alkalinity of the water. Copper is much more

toxic to organisms found in waters with low

alkalinity than in waters with high alkalinity

(U.S. Environmental Protection Agency, 1976). The

USEPA recommends that the concentration of

copper not exceed 13 μg/L in water with a mean

alkalinity of 100 mg CaCO3/L for aquatic

organisms and an action level of 1,300 μg/L for

drinking water. The chronic aquatic-life standard in

Kentucky is 12 μg/L, assuming a mean alkalinity of

100 mg CaCO3/L. The Kentucky domestic water

supply criteria is the same as USEPA’s (1,300 μg/L)

standard.

Samples analyzed for copper were collected

at 24 sites. Concentrations ranged from 0.5 μg/L at

Cumberland River at Burkesville to 88 μg/L at

Tradewater River at Olney (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from <0.01 ton/yr at several sites

to 0.9 ton/yr at Bayou de Chien near Clinton

(table 6). Mean annual base-flow loads ranged from

<0.01 ton/yr at several sites to 0.2 ton/yr at Green

River at Paradise (table 6). Mean annual total-flow

yields ranged from <0.01 ton/mi2 at several sites to

0.02 ton/mi2 at Salt River at Shepherdsville and

Pond Creek near Louisville (table 6). Mean annual

base-flow yields were <0.01 ton/mi2 at all sites

(table 6). The mean and median aggregate total-flow

yields were 0.01 and <0.01 ton/mi2, respectively

(table 5).

Iron

Iron is an essential element to the metabolism

of plants and animals. The solubility of iron in water

depends strongly on the amount of oxygen present

in the system as well as the pH (Hem, 1989, p. 76).

If present in high concentrations, iron can cause

taste or stain problems in domestic and industrial

water supplies (Hem, 1989, p. 76). The chronic

criterion of 1,000 μg/L of iron in streams has been

established by the KDOW as a criterion for

warmwater aquatic habitats in Kentucky.

Samples analyzed for iron were collected at

24 sites. Concentrations ranged from 2.3 μg/L at

Mayfield Creek near Blandville to 49,000 μg/L at

Green River at Paradise (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 0.2 ton/yr at Horse Lick

Creek near Lamero to 334 ton/yr at Kinniconick

Creek near Tannery (table 6). Mean annual baseflow loads ranged from 0.04 ton/yr at Horse Lick

Creek near Lamero to 131 ton/yr at Green River at

Paradise (table 6). Mean annual total-flow yields

ranged from 0.3 ton/mi2

 at Horse Lick Creek near

Lamero to 166 ton/mi2

 at Kinniconick Creek near

Tannery (table 6). Mean annual base-flow yields

ranged from 0.1 ton/mi2 at Horse Lick Creek near

Lamero to 4 ton/mi2 at Little River near Cadiz

(table 6). The mean and median aggregate total-flow

yields were 16 and 5 ton/mi2, respectively (table 5).
LOADS AND YIELDS OF SUSPENDED SOLIDS AND SELECTED WATER-QUALITY CONSTITUENTS 27

Lead

Lead is widely distributed throughout the

environment. The toxicity of lead depends on its

solubility, which in turn depends on pH (Hem, 1989,

p. 143). Lead enters natural water from the

atmosphere, runoff, or wastewater; little is

transferred from natural ores. Lead may enter the

environment during mining, refining use, recycling,

and combustion of coal for fuel

(U.S. Environmental Protection Agency, 1999). The

USEPA drinking-water standard for lead is 15 μg/L;

most of the sites had maximum concentration values

greater than 15 μg/L (table 7).

Samples analyzed for lead were collected at

24 sites. Concentrations ranged from 0.3 μg/L at

Levisa Fork at Paintsville to 4.5 μg/L at Rough

River near Dundee (table 7). Loads were determined

for 22 of the 24 sites. Mean annual total-flow loads

ranged from <0.01 ton/yr at several stations to

1 ton/yr at Tygarts Creek near Load (table 6). Mean

annual base-flow loads ranged from <0.01 ton/yr at

several sites to 0.1 ton/yr at Green River at Paradise

(table 6). Mean annual total-flow yields ranged from

<0.01 ton/mi2 at several sites to 0.2 ton/mi2

 at Salt

River at Shepherdsville, Pond Creek near

Louisville, Rough River near Dundee, and

Cumberland River at Pineville (table 6). Mean

annual base-flow yields ranged from <0.01 ton/mi2

at most sites to 0.01 ton/mi2 at Salt River at

Shepherdsville, Rough River near Dundee, and

Little River near Cadiz (table 6). The mean

and median aggregate total-flow yields were 0.01

and 0.01 ton/mi2, respectively (table 5).

Manganese

Water supply companies consider manganese

an undesirable element because in high

concentrations it can cause stains and objectionable

tastes (Hem, 1989, p. 84); however, it is an

important element in natural waters to plant and

animal metabolism. Streams near coal mines usually

have elevated concentrations of manganese because

of acid-mine drainage (Handy, 1982).

Samples analyzed for manganese were

collected at 24 sites. Concentrations ranged from

1.0 μg/L at Kinniconick Creek near Tannery,

Cumberland River at Burkesville, Horse Lick Creek

near Lamero, and Cumberland River at Pineville to

4.6 μg/L at Mayfield Creek at Blandville (table 7).

Loads were determined for 22 of the 24 sites. Mean

annual total-flow loads ranged from <0.01 ton/yr at

Horse Lick Creek near Lamero to 31 ton/yr at

Tygarts Creek near Load (table 6). Mean annual

base-flow loads ranged from <0.01 ton/yr at Horse

Lick Creek near Lamero to 4.1 ton/yr Kinniconick

Creek near Tannery (table 6). Mean annual totalflow yields ranged from <0.01 ton/mi2 at Horse Lick

Creek near Lamero to 13 ton/mi2

 at Tygarts Creek

near Load (table 6). Mean annual base-flow yields

ranged from <0.01 ton/mi2 at Horse Lick Creek near

Lamero and Green River at Paradise to 0.2 ton/mi2

at Rough River near Dundee and Bayou de Chien

near Clinton (table 6). The mean and median

aggregate total-flow yields were 1 and 0.3 ton/mi2

,

respectively (table 5).

Mercury

Mercury is ubiquitous in the environment and

occurs in several different forms—from elemental to

dissolved inorganic and organic species

(U.S. Environmental Protection Agency, 1999).

Industry and agriculture are ways that mercury can

enter natural waters (U.S. Environmental Protection

Agency, 1999). The USEPA drinking-water

standard is 2 μg/L for inorganic mercury. Less than

20 percent of the 2,525 analyses among the

24 stations for total mercury exceeded 0.1 μg/L.

Samples analyzed for mercury were collected

at 24 sites. Concentrations ranged from 0.5 μg/L at

Cumberland River at Burkesville to 8 μg/L at Salt

River at Shepherdsville (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from <0.01 ton/yr at most sites to

0.01 ton/yr at Cumberland River at Burkesville

(table 6). Mean annual base-flow loads were

<0.01 ton/yr at all sites (table 6). Mean annual totalflow yields were <0.01 ton/mi2 at all sites (table 6).

Mean annual base-flow yields were

<0.01 ton/mi2

 at all sites (table 6). The mean and

median aggregate total-flow yields were <0.01

and <0.01 ton/mi2

, respectively (table 5).

Zinc

Zinc is found in moderate abundance in

sedimentary rocks (Hem, 1989, p. 142); however,

modern industrial civilization has greatly enhanced

the presence of zinc in natural waters. It is used

extensively in metallurgy for galvanizing steel and

in making paints and rubber products (Hem, 1989,

p. 142). The Kentucky warmwater-aquatic habitat

criterion for zinc is dependent on the hardness of the

water. The recommended USEPA drinking-water

standard is 5,000 μg/L.

Samples analyzed for zinc were collected at

24 sites. Concentrations ranged from 0.5 μg/L at

Cumberland River at Burkesville to 1,650 μg/L at

Mayfield Creek at Blandville (table 7). Loads were

determined for 22 of the 24 sites. Mean annual totalflow loads ranged from 0.01 ton/yr at Horse Lick

Creek near Lamero to 2.1 ton/yr at Cumberland

River at Burkesville (table 6). Mean annual baseflow loads ranged from <0.01 ton/yr at Horse Lick

Creek near Lamero, Bayou de Chien near Clinton,

and Mud River near Gus to 0.5 ton/mi2 at Green

River at Paradise (table 6). Mean annual total-flow

yields ranged from 0.01 ton/mi2 at Mud River near

Gus and Pond River near Madisonville to

0.1 ton/mi2 at Rough River near Dundee (table 6).

Mean annual base-flow yields ranged from

<0.01 ton/mi2 at most sites to 0.05 ton/mi2 at Rough

River near Dundee (table 6). The mean and median

aggregate total-flow yields were 0.04 and

0.03 ton/mi2, respectively (table 5).

COMPARISON OF SUSPENDED

SOLIDS AND NUTRIENT YIELDS

TO PREDOMINANT LAND USE

The major land-use categories in the basins

studied were forest (12 basins), agriculture

(9 basins), and urban (1 basin). The distribution of

constituents in the water in most of these basins

somewhat reflects the effect of multiple land uses.

Except for six basins, all sites have at least

20 percent of their land use as forest, and six basins

have more than 70 percent of their land use as

agriculture (table 3). In general, the loads of

nutrients and suspended solids in agricultural basins

equal or exceed those in forested basins of similar

size.

Annual total-flow and base-flow yields of

nitrite plus nitrate, ammonia plus organic nitrogen,

total phosphorus, and suspended solids for the

period of record at each station are summarized in

box plots (6, 7, 8, and 9). Stations are grouped

according to their drainage basin size for

comparisons of yields in basins of similar size and

different land uses. The years of total-flow and baseflow yield estimates range from 3 to 18 years for the

stations.

Forested Drainage Basins

Twelve drainage basins were categorized/

classified as being forested, with forests covering

from 44 to 96 percent of the basin land area. Totalflow and base-flow yields of nutrients (ammonia

plus organic nitrogen, nitrite plus nitrate, and total

phosphorus) were generally less than 1 (ton/mi2)/yr

in forested drainage basins (figs. 6, 7, and 8).

Typically, nutrient yields from undisturbed forested

land are lower than those from urban and

agricultural land. According to the U.S. Department

of Agriculture (1992), forests can reduce the

amount of nitrogen in surface-water runoff and

shallow ground water by as much as 80 percent. The

smallest total-flow yields for nitrite plus nitrate were

estimated at Levisa Fork Basin, in which 95 percent

of the land is forested. This basin also had one of the

smallest total-flow yields of ammonia plus organic

nitrogen and total phosphorus. Total-flow yields of

suspended solids were generally lower in forested

basins than agricultural and urban basins. Median

annual total-flow yields of suspended solids were 65

and 177 (ton/mi2)/yr within the forested land use

basins and agricultural land use basins, respectively.

Agricultural Drainage Basins

In most of the basins, total-flow yields for

nutrients (ammonia plus organic nitrogen, nitrite

plus nitrate, and total phosphorus) were generally

less than 2 (ton/mi2

)/yr. In general, nutrient baseflow yields of agricultural land followed a similar

pattern as total-flow yields.

Some of the largest estimated total-flow

yields of nutrients and suspended solids among

agricultural basins were for streams in the Licking

River Basin, the North Fork Licking River near

Milford, and the South Fork Licking River at

Cynthiana. Agricultural land constitutes 77 and

94 percent of the drainage area in the North Fork

and South Fork Licking River Basins, respectively.

Possible sources of nutrients discharging into the

Licking River are agricultural and residential

fertilizers, and other sources.

Estimated base-flow yields of nutrients and

suspended solids at Little River near Cadiz, Rough

River near Dundee, Green River at Paradise, and

Mud River near Gus were nearly half of their

estimated total-flow yields (fig. 9). These four

basins are located in karst terrain making the ground

water much more susceptible to contamination from

overlying land uses. The pipe-like-solutional

openings (conduits) and fractures that make up the

subsurface karst drainage system are a factor in the

relatively rapid transport of nutrients and suspended

solids by ground water to surface water.

Urban Drainage Basins

Urban land constituted 62 percent of the

drainage area of Pond Creek. This was the only site

categorized as urban; all other sites had less than

10 percent urban land (table 3). In general, nutrient

(ammonia plus organic nitrogen, nitrite plus nitrate,

and total phosphorus) total-flow and base-flow

yields were higher in this urban basin than in the

forested or agricultural basins (figs. 6, 7, and 8).

However, the total-flow and base-flow yields of

suspended solids in the urban basin equaled or

exceeded those in the agricultural basins of equal or

greater size. Potential factors that affect the

magnitude of suspended solids yields include pointsource discharges and their magnitude as well as the

percentage of industrial and residential sources

located within the urban setting.

34 Estimated Loads and Yields of Suspended Solids and Water-Quality Constituents in Kentucky Streams

SUMMARY

Loads and yields of suspended solids and

selected water-quality constituents were estimated

for 22 of the 44 stations in the Kentucky Ambient

Surface-Water Monitoring Network to determine

the relative methods of constituent transport as total

flow or base flow. Suspended solids and waterquality data were retrieved from the

U.S. Environmental Protection Agency’s (USEPA)

Storage and Retrieval (STORET) data base for

samples collected by the Kentucky Division of

Water, and daily discharge data were obtained from

U.S. Geological Survey (USGS) streamflow

records. Daily mean discharge for ungaged stations

or for stations with incomplete records (missing

data) were synthesized using drainage-area ratio,

regression analysis, or a combination of the two

techniques. Stream discharge was partitioned into

base-flow and surface-runoff components by the use

of USGS software, and loads were estimated by the

use of ESTIMATOR and FLUX computer

programs. Principal results of the analyses are as

follows:

• Suspended solids—Mean annual total-flow

loads for suspended solids ranged from

850 tons per year (ton/yr) at Horse Lick

Creek near Lamero to 771,000 ton/yr at

Green River at Paradise. Mean annual

base-flow loads for suspended solids

ranged from 10 ton/yr at Horse Lick Creek

near Lamero to 345,000 ton/yr at Green

River at Paradise.

• Fecal-coliform bacteria—Kentucky’s

primary- and secondary-contact recreation

water criteria for fecal-coliform bacteria

are 200 and 100 colonies per

100 milliliters (col/100 mL), respectively,

as a geometric mean based on no less than

five samples per month. Approximately 45

and 82 percent of the median fecalcoliform densities were above the primary

and secondary recreational contact

standards, respectively. Tug Fork at

Kermit, West Virginia, had the highest

median densities of fecal coliform

(630 col/100 mL). Many sites had

densities of less than 1 col/100 mL.

• Major ions—The major ions analyzed were

calcium, magnesium, potassium, sodium,

chloride, and sulfate. Bayou de Chien near

Clinton had the smallest mean annual

total-flow loads for calcium (8.2 ton/yr)

and magnesium (3.0 ton/yr). The mean

annual total-flow loads for the other major

ions were smallest at Horse Lick Creek

near Lamero. Green River at Paradise had

the largest mean annual total-flow loads

for all major ions, except sodium. Mean

annual base-flow loads for all major ions

were smallest at Horse Lick Creek near

Lamero.

• Nutrients—Nutrients analyzed were

ammonia, ammonia plus organic nitrogen,

nitrite plus nitrate, and total phosphorus;

total organic carbon also was analyzed.

Horse Lick Creek near Lamero had the

smallest mean annual total-flow and baseflow loads for those nutrients and total

organic carbon. Mean annual total-flow

loads for ammonia and total phosphorus

were largest at Salt River at

Shepherdsville. Green River at Paradise

had the largest mean annual total-flow

loads for nitrite plus nitrate, ammonia plus

organic nitrogen, and total organic carbon.

Mean annual base-flow loads for all

nutrients and total organic carbon were

smallest at Horse Lick Creek near Lamero

and largest at Green River at Paradise.

• Major metals and trace elements—The

major metals and trace elements analyzed

were aluminum, arsenic, barium,

cadmium, chromium, copper, iron, lead,

manganese, mercury, and zinc. The

median concentrations for total lead at Salt

River at Shepherdsville and Pond Creek

near Louisville exceeded the

U.S. Environmental Protection Agency

drinking water standard. Horse Lick Creek

near Lamero had the smallest mean annual

total-flow and base-flow loads for all

major metals and trace elements. The

mean annual total-flow and base-flow

yields of most metals and trace elements at

most sites were equally low.

The loads and yields nutrients and suspended

solids in streams are related to land-use practices.

As the intensity of the land use increases, so do the

loads and yields of nutrients and suspended solids.
SUMMARY 35

Major sources of nutrients include wastewatertreatment plant discharges, fertilizers from

agricultural and residential areas, and faulty septic

tanks. In Kentucky, the largest sources of suspended

solids include construction sites, erosion from

agricultural land, logging operations, and surface

mining.

Estimated total-flow yields of nutrients

(ammonia plus organic nitrogen, nitrite plus nitrate,

and total phosphorus) were generally less than

1 ton per square mile per year ((ton/mi

2

)/yr) in

forested basins. In general, the total-flow yields for

ammonia plus organic nitrogen and nitrite plus

nitrate were generally smaller in forested basins.

The median annual total-flow yields of suspended

solids were smaller in forested basins

(65 (ton/mi

2

)/yr) than in agricultural basins

(177 (ton/mi

2

)/yr).

Fertilizers from agricultural nonpoint sources

may contribute substantial nutrient inputs into some

basins; however, this does not always result in large

loads of nutrients in streams. Estimates of total-flow

yields of nutrients (ammonia plus organic nitrogen,

nitrite plus nitrate, and total phosphorus) were

typically less than 2 (ton/mi

2

)/yr. Some of the

largest total-flow yields of nutrients and suspended

solids were estimated in the Licking River Basin.

Estimated base-flow yields of suspended solids at

several basins located in the larger Green River and

Lower Cumberland River Basins were about half of

their estimated total-flow yields of suspended solids.

The karst terrain in which these basins are located

makes them much more susceptible to ground-water

contamination, especially if a confining unit is thin

or absent.

Of the 24 stations in phase II, only one station

had greater than 50 percent urban land use. In

general, the estimated nutrient yields in this urban

basin were larger than in the forested or agricultural

basins. Additional monitoring is needed to quantify

nonpoint source nutrient yields from the various

urban land uses, because nonpoint source

information for urban basins is limited.
