Chloride in Ground Water and Surface Water in the

Vicinity of Selected Surface-Water Sampling Sites of the

Beneficial Use Monitoring Program of Oklahoma, 2003

By Shana L. Mashburn and Michael P. Sughru

Abstract

The Oklahoma Water Resources Board Beneficial Use

Monitoring Program reported exceedances of beneficial-use

standards for chloride at 11 surface-water sampling sites from

January to October 2002. The U.S. Geological Survey, in cooperation with the Oklahoma Department of Environmental Quality, conducted a study to determine the chloride concentrations

in ground water in the vicinity of Beneficial Use Monitoring

Program surface-water sampling sites not meeting beneficial

use standards for chloride and compare chloride concentrations

in ground water and surface water. The chloride-impaired Beneficial Use Monitoring Program surface-water sampling sites

are located in the western and southern regions of Oklahoma.

The ground-water sampling sites were placed in proximity to

the 11 surface-water sampling sites designated impaired by

chloride by the Oklahoma Water Resources Board. Two surface-water sampling sites were located on the Beaver River

(headwaters of the North Canadian River), three sites on the

Cimarron River, one site on Sandy Creek, one site on North

Fork Red River, and four sites on the Red River.

Six ground-water samples were collected, when possible,

from two test holes located upstream from each of the 11 Beneficial Use Monitoring Program surface-water sampling sites.

One test hole was placed on the left bank and right bank, when

possible, of each Beneficial Use Monitoring Program surfacewater sampling site. All test holes were located on alluvial

deposits adjacent to the Beneficial Use Monitoring Program

surface-water sampling sites within 0.5 mile of the stream. Top,

middle, and bottom ground-water samples were collected from

the alluvium at each test hole, when possible. Water properties

of specific conductance, pH, water temperature, and dissolved

oxygen were recorded in the field before sampling for chloride.

The ground-water median chloride concentrations at 8 of

the 11 Beneficial Use Monitoring Program sites were less than

the surface-water median chloride concentrations. The Turpin

and Beaver sites had similar ground-water and surface-water

median chloride concentrations. The Buffalo site was the only

site that had a large difference between the ground-water and

surface-water chloride concentrations. The ground-water

median chloride concentration was approximately 14,500 mg/L

greater than the surface-water median chloride concentration at

the Buffalo site.

Introduction

The Beneficial Use Monitoring Program (BUMP) of Oklahoma, under the direction of the Oklahoma Water Resources

Board (OWRB), consists of sampling 100 surface-water sites

10 times annually (Oklahoma Water Resources Board, 2002).

The program monitors whether concentrations in streams and

lakes meet or exceed beneficial-use standards established by the

State for section 303d of the Clean Water Act. The OWRB

reported exceedances of beneficial-use standards for chloride at

11 surface-water sampling sites from January to October 2002.

The OWRB uses the agriculture beneficial-use standard for

chloride as the criteria for designating a stream impaired by

chloride (Oklahoma Water Resources Board, 2002). The

OWRB standard for chloride is based on the yearly mean of

chloride concentrations in samples from the previous years. The

U.S. Geological Survey (USGS), in cooperation with the Oklahoma Department of Environmental Quality (ODEQ), conducted a study to determine the chloride concentrations in

ground water in the vicinity of BUMP surface-water sampling

sites not meeting beneficial-use standards for chloride and compare chloride concentrations in ground water and surface water.

A comparison of chloride concentrations in ground water and

surface water is needed to determine the possible role that

sources of chloride in ground water may have in affecting large

chloride concentrations at the BUMP surface-water sampling

sites.

Purpose and Scope

The purpose of this report is to (1) present chloride concentrations in local ground water adjacent to 11 chlorideimpaired BUMP surface-water sampling sites, and (2) compare

chloride concentrations of the ground-water sites to chloride

concentrations of the BUMP surface-water sampling sites. The

relative volume of ground water discharging to the stream compared to the volume of streamflow determines whether the chloride concentrations in ground water could increase or decrease

chloride concentrations in the stream. The effects of these relative volumes are not addressed in this report. Ground-water

samples were collected from two test holes located upstream

from each BUMP surface-water sampling site from August to

December 2003. The ground-water samples were collected by

USGS personnel and analyzed by ODEQ laboratory. The sur-
2 Chloride in Ground Water and Surface Water in the Vicinity of Selected Surface-Water Sampling Sites of the Beneficial Use

Monitoring Program of Oklahoma, 2003

face-water chloride data were collected from December 1998 to

October 2002. The surface-water chloride data used in this

report were collected by OWRB personnel and analyzed by

ODEQ laboratory.

Description of Sampling Sites

The chloride-impaired BUMP surface-water sampling

sites were located in the western and southern regions of Oklahoma. The ground-water sampling sites were placed in proximity to the 11 surface-water sampling sites designated impaired

by chloride by the OWRB (Oklahoma Water Resources Board,

2002). Two surface-water sampling sites were located on the

Beaver River (headwaters of the North Canadian River), three

sites on the Cimarron River, one site on Sandy Creek, one site

on North Fork Red River, and four sites on the Red River (fig.

1).

Beaver River

The ground-water and surface-water sampling sites on

Beaver River, Turpin (AT233900) were located near U.S. Highway 83 (fig. 2). The Beaver River channel and floodplain consists of Quaternary-age alluvium composed of sand, gravel, silt,

and clay (Morton and Goemaat, 1973). The alluvium is unconfined and uncemented and yields about 400 to 2,000 gallons per

minute (gpm) to wells (Morton and Goemaat, 1973). The alluvium on the left bank (northwest) is in contact with Tertiary-age

Ogallala Formation1. The Ogallala consists of interbedded

sand, siltstone, clay, gravel lenses, and thin limestone (Morton

and Goemaat, 1973). It is partly consolidated by calcium carbonate, and caliche is found near the surface (Marine and

Schoff, 1962). The Ogallala is the principal aquifer in Beaver

County and yields 200 to 1,760 gpm to wells (Morton and Goemaat, 1973). It is hydraulically connected to the alluvium and

water passes freely from one to the other (Marine and Schoff,

1962). Water from the Ogallala is moderately hard (Marine and

Schoff, 1962). The alluvium on the right bank (southeast) is in

contact with Quaternary-age dune sand and Permian-age reddish sandstone, siltstone, and shale with lesser amounts of limestone, dolomite, gypsum, and salt (Morton and Goemaat, 1973).

The dune sand is composed of windblown deposits of fine, subrounded grains of sand (Morton and Goemaat, 1973). The dune

sand is hydraulically connected to the underlying units by

absorbing and transmitting precipitation (Marine and Schoff,

1962). The lower part of the Permian-age units acts as a confining layer that creates a saturated zone where water flows laterally to discharge in springs (Marine and Schoff, 1962). Wells in

the Permian-age units yield small amounts of water that are

very hard and contain large concentrations of sulfate and chloride (Marine and Schoff, 1962).

The ground-water and surface-water sampling sites on

Beaver River, Beaver (AT234000) were located near U.S.

Highway 270 (fig. 3). The USGS maintains a real-time surfacewater station near the Beaver site (07234000). Mean annual discharge near the Beaver site was 0.075 cubic feet per second

(ft3/s) for the 2002 water year (Blazs and others, 2003a). The

Beaver River channel and floodplain characteristics at the Beaver site are similar to the Turpin site. The alluvium on the left

bank (north) is in contact with Permian-age units and Quaternary-age dune sand. The alluvium on the right bank (south) is

in contact with the Tertiary-age Ogallala Formation.

Cimarron River

The ground-water and surface-water sampling sites on

Cimarron River, Mocane (AT157000) were located near north

1510 Road (fig. 4). The USGS maintains a real-time surfacewater station located approximately 11 miles upstream from the

Mocane site (07156900). Mean annual discharge at station

07156900 near the Mocane site was 31.39 ft3/s for the 2002

water year (Blazs and others, 2003a). More surface water flows

through the Mocane site than at the Beaver site. The Cimarron

River channel width is larger than the Beaver River channel

width. The Cimarron River channel and floodplain consists of

Quaternary-age alluvium composed of sand, gravel, silt, and

clay (Morton and Goemaat, 1973). The alluvium is unconfined

and uncemented and yields about 400 to 2,000 gpm to wells

(Morton and Goemaat, 1973). The alluvium on the left bank

(north) and right bank (south) is bordered by Tertiary-age Ogallala Formation. Some Quaternary-age dune sand also occurs

near the alluvium. The dune sand is composed of windblown

deposits of fine, subrounded grains of sand (Morton and Goemaat, 1973).

The ground-water and surface-water sampling sites on

Cimarron River, Buffalo (AT157950) were located near U.S.

Highway 64 (fig. 5). The USGS maintains a real-time surface

water station near the Buffalo site (07157950). Mean annual

discharge at station 07157950 near the Buffalo site was 18.78

ft3/s for the 2002 water year (Blazs and others, 2003a). The alluvium on the left bank (east) is in contact with Quaternary-age

terrace deposits. The terrace deposits consist of gravel, sand,

silt, clay, and volcanic ash, which also include sand dunes that

are common in the area (Morton, 1980). The alluvium on the

right bank (west) is in contact with Permian-age Flowerpot

Shale. The Flowerpot Shale consists of red-brown silty shale

with some thin gypsum and dolomite beds, and rock salt in the

middle and upper parts (Morton, 1980). Springs are common

near the contact between the Permian-age units and the overlying Quaternary-age units (Myers, 1959). The Permian-age units

yield up to 50 gpm to wells (Myers, 1959). Water from the Permian units contains large concentrations of dissolved gypsum

(Myers, 1959).

The ground-water and surface-water sampling sites on

Cimarron River, Orienta (AT158110) were located near U.S.

Highway 412 (fig. 6). The USGS maintains a real-time surface

water station located approximately 30 miles upstream from the

Orienta site (07158000). Mean annual discharge at station

07158000 near the Orienta site was 46.01 ft3/s for the 2002

water year (Blazs and others, 2003a). The Cimarron River channel and floodplain characteristics at the Orienta site are similar

to the Buffalo site. The alluvium on the left bank (northeast) is

in contact with Quaternary-age terrace deposits and the alluvium on the right bank (southwest) is in contact with Permianage Cedar Hills Sandstone. The Cedar Hills sandstone consists

of orange-brown to greenish-gray fine-grained sandstone and

siltstone, with some red-brown shale (Morton, 1980). Wells in

the Cedar Hills yield 150 to 300 gpm (Morton, 1980).

Sandy Creek

The ground-water and surface-water sampling sites on

Sandy Creek, Eldorado (AT299710) were located near State

Highway 6 (fig. 7). The Sandy Creek channel and floodplain

consists of Quaternary-age alluvium composed of sand, clay,

and gravel (Havens, 1977). The extent of the Sandy Creek alluvium at the Eldorado site is limited. Wells in the Quaternaryage alluvium yield from 300 to 2,500 gpm (Havens, 1977). The

alluvium on the left bank (east) and right bank (west) is in contact with the Permian-age Van Vacter Member and Elm Fork

Member. The Van Vacter and Elm Fork Members consist of

dolomite-gypsum-shale sequences (Havens, 1977). The Van

Vacter and Elm Fork Members contain calcium sulfate and

sodium chloride water types (Havens, 1977).

North Fork Red River

The ground-water and surface-water sampling sites on

North Fork Red River, Headrick (AT305000) were located near

U.S. Highway 62 (fig. 8). The USGS maintains a real-time surface water station near the Headrick site (07305000) located on

the downstream side of bridge on U.S. Highway 62. Mean

annual discharge at station 07305000 near the Headrick site was

68.25 ft3/s for the 2002 water year (Blazs and others, 2003b).

The North Fork Red River channel and floodplain consists of

Quaternary-age alluvium composed of sand, clay, and gravel

(Havens, 1977). The alluvium on the left bank (east) is in contact with Quaternary-age terrace deposits. The alluvium on the

right bank (west) is in contact with Cambrian-age Wichita

Granite Group and Quaternary-age terrace deposits. The terrace

deposits consist of sand, clay, and gravel that are hydraulically

connected to the alluvium (Havens, 1977). The Cambrian-age

Wichita Granite Group is composed of various textures of granite (Havens, 1977).

Red River

The ground-water and surface-water sampling sites on the

Red River, Davidson (AT308000) were located near U.S. Highway 183 (fig. 9). The Pease River is the tributary upstream from

the Red River near the Davidson site. The Red River channel

and floodplain consists of Quaternary-age alluvium composed

of sand, clay, and gravel (Havens, 1977). The Red River alluvium is extensive at the Davidson site. The alluvium is unconfined and uncemented and yields up to 2,500 gpm to wells

(Havens, 1977). The alluvium on the left bank (north) and right

bank (south) is bordered by Quaternary dune sand that is composed of windblown deposits of fine, subrounded grains of sand

(Havens, 1977).

The ground-water and surface-water sampling sites on the

Red River, Waurika (AT312720) were located near State Highway 79 (fig. 10). The USGS maintains a real-time surface water

station located approximately 35 miles upstream from the Waurika site (07308500). Mean annual discharge at station

07308500 near the Waurika site was 371.3 ft3/s for the 2002

water year (Blazs and others, 2003b). The alluvium on the left

bank (east) is in contact with Pennsylvanian-age Oscar Group.

The Oscar Group consists of shale and sandstone (Havens,

1977). Wells in the Oscar yield from 0 to 25 gpm (Havens,

1977). The alluvium on the right bank (west) is in contact with

Quaternary-age terrace deposits. The terrace deposits consist of

sand, clay, and gravel (Havens, 1977).

The ground-water and surface-water sampling sites on the

Red River, Terral (AT315500) were located near U.S. Highway

81 (fig. 11). The USGS maintains a real-time surface water station near the Terral site (07315500) located on downstream side

of bridge on U.S. Highway 81. Mean annual discharge at station

07315500 near the Terral site was 848.0 ft3/s for the 2002 water

year (Blazs and others, 2003b). The alluvium on the left bank

(north) is in contact with the Pennsylvanian-age Oscar Group.

The alluvium on the right bank (south) is in contact with Quaternary-age terrace deposits.

The ground-water and surface-water sampling sites on the

Red River, Hugo (AT335500) were located near U.S. Highway

271 (fig. 12). The USGS maintains a real-time surface water

station near Hugo (07335500) located on downstream side of

bridge on U.S. Highway 271. Mean annual discharge at station

07335500 near the Hugo site was 8,725 ft3/s for the 2002 water

year (Blazs and others, 2003b). The alluvium on the left bank

(north) and right bank (south) is bordered by Quaternary-age

terrace deposits. The terrace deposits consists of gravel, sand,

silt, clay and volcanic ash and yields 100 to 500 gpm to wells

(Marcher and Bergman, 1983).

Monitoring Program of Oklahoma, 2003

Possible Sources of Chloride

Possible anthropogenic sources of chloride are septic

waste, wastewater treatment plant effluent, industrial waste,

animal waste, fertilizer, road salting for de-icing of roadways,

and produced water from oilfield operations. Possible natural

sources of chloride are precipitation and geologic units containing chloride. These chloride sources could possibly be located

upstream at great distances or nearby the surface-water sampling sites. Each of these sources would contribute varying

amounts of chloride to the sampled streams depending on the

output chloride concentrations. The determination of sources of

chloride near the BUMP sites was not within the scope of the

study.

Methods and Sampling Procedures

Six ground-water samples were collected, when possible,

from two test holes located upstream from each of the 11 Beneficial Use Monitoring Program surface-water sampling sites.

One test hole was placed on the left bank and right bank, when

possible, of each BUMP surface-water sampling site. Left bank

and right bank designations were assigned by looking downstream. Top, middle, and bottom ground-water samples were

collected from the alluvium at each test hole, when possible.

Only five ground-water samples were obtained at Orienta, due

to limited alluvial thickness on the right bank. Only four

ground-water samples were obtained at Eldorado due to the limited alluvial thickness on the left and right bank. Only four

ground-water samples were obtained at Davidson due to the

limited alluvial thickness on the right bank. Only three groundwater samples were obtained from the right bank at the Waurika

site, because the left bank was inaccessible.

All test holes were located on alluvial deposits adjacent to

the BUMP surface-water sampling sites within 0.5 mile of the

stream. Test hole locations depended on landowner permission

and road accessibility. Site locations were determined using a

global positioning system with a horizontal accuracy of about

10 feet.

A truck-mounted Geoprobe was used to make the temporary test holes. A Geoprobe is a hydraulically powered sampling and logging tool that uses both static force and percussion

to advance into the ground. No materials were permanently

installed in the ground. A 1-foot long stainless steel screen of

1.25-inch diameter was driven into the ground to collect water

samples. Top, middle, and bottom ground-water samples were

collected from the alluvium at each test hole, when possible.

First, the screen was driven down to the top of the water table

to collect a top sample. Then, the screen was driven until the

penetration slowed markedly at the assumed bedrock or clay

boundary at the base of the alluvium to collect a bottom sample.

Finally, the screen was pulled up to the midpoint between the

top and bottom to collect a middle sample. Polyethylene tubing

and a peristaltic pump were used to pump water samples to the

surface for collection. Each sampling level (top, middle, bottom) in the test hole was purged for approximately 15 minutes

and water properties of specific conductance, pH, water temperature, and dissolved oxygen were measured. Samples were

collected after water properties stabilized to assure that a representative sample was collected from the alluvium. Field water

property data are listed in Appendix 1.

Chloride samples were collected as whole water samples

in 250-milliliter polyethylene bottles. Each sample was

assigned a local identifier made up of two letters identifying left

bank (LB) or right bank (RB), the OWRB surface-water sampling site identification number (335500), and a letter identifying top sample (T), middle sample (M), or bottom sample (B).

For example, a top sample taken from the left bank of the Hugo,

Oklahoma, site would have a local identifier of LB335500T.

After samples were collected, they were sent to the ODEQ laboratory to be analyzed for chloride concentration using a colorimetric, automated ferricyanide method (U.S. Environmental

Protection Agency, 1979).

Quality-assurance samples were collected to evaluate the

degree of accuracy, precision, and bias of chloride samples.

One equipment blank was prepared in the laboratory by processing blank water through all sampling equipment before initial field sampling proceeded. Five field blanks were prepared

in the field by processing blank water in exactly the same manner as the chloride samples. Six replicate samples (10 percent of

samples) were prepared in the field by filling a second bottle

after the initial chloride sample was collected. Quality-assurance data are listed in Appendix 2.

The surface-water chloride data used in this report were

collected by OWRB personnel and analyzed by ODEQ laboratory (Appendix 3). OWRB personnel measured the water properties in the field.

Chloride in Ground Water and Surface

Water

The two surface-water sampling sites on the Beaver River

were near Turpin, (AT233900); and Beaver, (AT234000) Oklahoma (fig. 1). The ground-water and surface-water medians for

chloride concentration were both approximately 2,600 milligrams per liter (mg/L) at Turpin (fig. 13 and table 1). The

ground-water chloride concentrations on the left bank were

slightly less than the chloride concentrations on the right bank

at the Turpin site. The ground-water chloride concentrations on

the left and right banks increased with depth at the Turpin site

(Appendix 1). The ground-water median chloride concentration

exceeded the surface-water median chloride concentration by

approximately 750 mg/L at Beaver (fig. 13 and table 1). All the

ground-water chloride concentrations at the Beaver site were

greater than the surface-water median chloride concentration.

The ground-water chloride concentrations on the left bank were

greater than the chloride concentrations on the right bank at the

Beaver site. The ground-water chloride concentrations on the

left and right banks decreased with depth at the Beaver site

(Appendix 1).

The three sites on the Cimarron River were near Mocane,

(AT157000); Buffalo, (AT157950); and Orienta, (AT158110)

Oklahoma. The ground-water median chloride concentration

was less than the surface-water median chloride concentration

by approximately 1,100 mg/L at Mocane (fig. 13 and table 1).

The ground-water chloride concentrations on the left bank were

greater than the chloride concentrations on the right bank at the

Mocane site. The ground-water chloride concentrations on the

left and right banks decreased with depth at the Mocane site

(Appendix 1). The ground-water median chloride concentration

was approximately 16,750 mg/L at Buffalo, which exceeded the

surface-water median chloride concentration of 2,247 mg/L

(fig. 13 and table 1). The ground-water chloride concentrations

on the left bank were larger than the chloride concentrations on

the right bank at the Buffalo site. The ground-water chloride

concentrations on the left and right banks increased with depth

at the Buffalo site (Appendix 1). The ground-water median

chloride concentration was less than the surface-water median

chloride concentration by approximately 2,500 mg/L at the Orienta site (fig. 13 and table 1). The ground-water chloride concentrations on the left bank were less than the chloride concentrations on the right bank at the Orienta site. The ground-water

chloride concentrations on the left bank increased with depth,

and on the right bank decreased with depth at the Orienta site

(Appendix 1).

The ground-water median chloride concentration at the

Eldorado, Oklahoma, site on Sandy Creek (AT299710) was less

than the surface-water median chloride concentration by

approximately 1,700 mg/L (fig. 13 and table 1). The groundwater chloride concentrations on the left bank were less than the

chloride concentrations on the right bank at the Eldorado site.

The ground-water chloride concentrations on the right and left

banks increased with depth at the Eldorado site (Appendix 1).

All the ground-water chloride concentrations were less

than the surface-water median chloride concentration of 2,084

mg/L at the Headrick, Oklahoma, site on the North Fork Red

River (AT305000) (fig. 13 and table 1). The ground-water chloride concentrations on the left bank were greater than the chloride concentrations on the right bank at the Headrick site. The

ground-water chloride concentrations on the right and left

banks increased with depth at the Headrick site (Appendix 1).

The four sites on the Red River were near Davidson,

(AT308000); Waurika, (AT312720); Terral, (AT315500); and

Hugo, (AT335500) Oklahoma. The ground-water median chloride concentration was less than the surface-water median chloride concentration by approximately 1,500 mg/L at the Davidson site (fig. 13 and table 1). The ground-water chloride

concentration in the top sample on the left bank was less than

the chloride concentration in the top sample on the right bank at

the Davidson site. The ground-water chloride concentrations

varied with depth at the Davidson site (Appendix 1). The

ground-water median chloride concentration was less than the

surface-water median chloride concentration at the Waurika site
Summary 19

(fig. 13 and table 1). Only right bank samples were collected at

the Waurika site. The ground-water chloride concentrations on

the right bank did not vary substantially with depth at the Waurika site (Appendix 1). The ground-water median chloride concentration was less than the surface-water median chloride concentration by approximately 800 mg/L at Terral (fig. 13 and

table 1). The ground-water chloride concentrations on the left

bank were less than the chloride concentrations on the right

bank at the Terral site. The ground-water chloride concentrations on the left and right banks increased with depth at the Terral site (Appendix 1). Three of the six ground-water samples

had chloride concentrations less than 10 mg/L at Hugo (fig. 13

and table 1). The other three ground-water samples had a

median chloride concentration of 14 mg/L, which was less than

the surface-water median chloride concentration at Hugo. The

ground-water chloride concentrations on the left and right

banks were similar and increased with depth at the Hugo site

(Appendix 1).

The ground-water median chloride concentrations at 8 of

the 11 BUMP sites were less than the surface-water median

chloride concentrations. The Turpin and Beaver sites had similar ground-water and surface-water median chloride concentrations. The Buffalo site was the only site that had a large difference between the ground-water and surface-water chloride

concentrations. The ground-water median chloride concentration was approximately 14,500 mg/L greater than the surfacewater median chloride concentration at the Buffalo site (fig. 13

and table 1).

There were some differences in ground-water chloride

concentrations between the left and right banks and with depth

at each site. Differences in ground-water chloride concentrations between the left and right banks may be due to differences

in alluvial materials, varying distances from the stream, differences in depth of alluvium, and differences in ground-water

flow gradients or directions. An increase in ground-water chloride concentrations with depth may indicate that chloride was

diluted near the surface due to recharge to the alluvium and/or

chloride was upwelling in ground-water from bedrock below

the alluvium. A decrease in ground-water chloride concentrations with depth may indicate that chloride was precipitating out

as salt crust near the surface due to evaporation and/or chloride

was leaching down from a source on the surface of the alluvium

and chloride concentrations were diluted by deeper ground

water.

The interaction of ground water and surface water in alluvial valleys is affected by local and regional flow systems that

could cause chloride concentrations to increase or decrease

within the alluvium. The effects of these flow systems are not

addressed in this report. Each water sample collected from the

alluvium or stream represents one point and time in the hydrologic system. The ground-water and surface-water samples

were collected during different years. The amount and distribution of precipitation from one year to the next can be significantly different, introducing some inconsistency in comparing

ground-water and surface-water chloride concentrations in this

report.

Summary

The Oklahoma Water Resources Board Beneficial Use

Monitoring Program reported exceedances of beneficial-use

standards for chloride at 11 surface-water sampling sites from

January to October 2002. The U.S. Geological Survey, in cooperation with the Oklahoma Department of Environmental Quality, conducted a study to determine the chloride concentrations

in ground water in the vicinity of Beneficial Use Monitoring

Program surface-water sampling sites not meeting beneficial

use standards for chloride and compare chloride concentrations

in ground water and surface water. The chloride-impaired Beneficial Use Monitoring Program surface-water sampling sites

are located in the western and southern regions of Oklahoma.

The ground-water sampling sites were placed in proximity to

the 11 surface-water sampling sites designated impaired by

chloride by the Oklahoma Water Resources Board. Two surface-water sampling sites were located on the Beaver River

(headwaters of the North Canadian River), three sites on the

Cimarron River, one site on Sandy Creek, one site on North

Fork Red River, and four sites on the Red River.

Six ground-water samples were collected, when possible,

from two test holes located upstream from each of the 11 Beneficial Use Monitoring Program surface-water sampling sites.

One test hole was placed on the left bank and right bank, when

possible, of each BUMP surface-water sampling site. All test

holes were located on alluvial deposits adjacent to the Beneficial Use Monitoring Program surface-water sampling sites

within 0.5 mile of the stream. Test hole locations depended on

landowner permission and road accessibility. Site locations

were determined using a global positioning system with a horizontal accuracy of about 10 feet. Top, middle, and bottom

ground-water samples were collected from the alluvium at each

test hole, when possible. Water properties of specific conductance, pH, water temperature, and dissolved oxygen were

recorded in the field before sampling for chloride.

Quality-assurance samples were collected to evaluate the

degree of accuracy, precision, and bias of chloride samples.

One equipment blank was prepared in the laboratory by processing blank water through all sampling equipment before initial field sampling proceeded. Five field blanks were prepared

in the field by processing blank water in exactly the same manner as the chloride samples. Six replicate samples (10 percent of

samples) were prepared in the field by filling a second bottle

after the initial chloride sample was collected.

The surface-water chloride data used in this report were

collected by OWRB personnel and analyzed by ODEQ laboratory. OWRB personnel measured the water properties in the

field.

The ground-water and surface-water medians for chloride

concentration were both approximately 2,600 mg/L at Turpin.

The ground-water median chloride concentration exceeded the

surface-water median chloride concentration by approximately

750 mg/L at Beaver. The ground-water median chloride con-

centration was less than the surface-water median chloride concentration by approximately 1,100 mg/L at Mocane. The

ground-water median chloride concentration was approximately 16,750 mg/L at Buffalo, which exceeded the surfacewater median chloride concentration of 2,247 mg/L. The

ground-water median chloride concentration was less than the

surface-water median chloride concentration by approximately

2,500 mg/L at the Orienta site. The ground-water median chloride concentration was less than the surface-water median chloride concentration by approximately 1,700 mg/L at the

Eldorado site. All the ground-water chloride concentrations

were less than the surface-water median chloride concentration

of 2,084 mg/L at the Headrick site. The ground-water median

chloride concentration was less than the surface-water median

chloride concentration by approximately 1,500 mg/L at the

Davidson site. The ground-water median chloride concentration

was less than the surface-water median chloride concentration

at the Waurika site. The ground-water median chloride concentration was less than the surface-water median chloride concentration by approximately 800 mg/L at Terral. Three of the six

ground-water samples had chloride concentrations less than 10

mg/L at Hugo. The other three ground-water samples had a

median chloride concentration of 14 mg/L, which was less than

the surface-water median chloride concentration at Hugo.

The ground-water median chloride concentrations at 8 of

the 11 Beneficial Use Monitoring Program sites were less than

the surface-water median chloride concentrations. The Turpin

and Beaver sites had similar ground-water and surface-water

median chloride concentrations. The Buffalo site was the only

site that had a large difference between the ground-water and

surface-water chloride concentrations. The ground-water

median chloride concentration was approximately 14,500 milligrams per liter greater than the surface-water median chloride

concentration.

There were some differences in ground-water chloride

concentrations between the left and right banks and with depth

at each site. Differences in ground-water chloride concentrations between the left and right banks may be due to differences

in alluvial materials, varying distances from the stream, differences in depth of alluvium, and differences in ground-water

flow gradients or directions. An increase in ground-water chloride concentrations with depth may indicate that chloride was

diluted near the surface due to recharge to the alluvium and/or

chloride was upwelling in ground-water from bedrock below

the alluvium. A decrease in ground-water chloride concentrations with depth may indicate that chloride was precipitating out

as salt crust near the surface due to evaporation and/or chloride

was leaching down from a source on the surface of the alluvium

and chloride concentrations were diluted by deeper ground

water.
