ABBREVIATED WATER-QUALITY UNITS

Chemical concentrations and water temperature are given only in metric units. Chemical 

concentration in water is given in milligrams per liter (mg/L) or micrograms per liter 

(μg/L). Milligrams per liter is a unit expressing the solute mass (milligrams) per unit volume 

(liter) of water. One thousand micrograms per liter is equivalent to 1 milligram per liter. 

For concentrations lower than 7,000 milligrams per liter, the numerical value is about the same 

as for concentrations in parts per million. Specific conductance is given in microsiemens per 

centimeter at 25 degrees Celsius (μs/cm at 25° C).

Abstract

The National Park Service initiated a Level 1 WaterQuality Inventory program to provide water-quality data to 

park managers so informed natural resource management 

decisions could be made. Level 1 water-quality data were 

collected by the U.S. Geological Survey Arizona Water 

Science Center at 57 sites in 13 National Park units located 

in the Southern Colorado Plateau Inventory and Monitoring 

network in water years 2005 and 2006. These data describe 

the current water-quality at selected sites within the park 

units and provide information for monitoring future trends. 

Water samples were collected three times at each type of site 

including wells, springs, seeps, tinajas, rivers, a lake, and an 

irrigation ditch. Field measurements were taken at each site 

and they included pH, specific conductance, temperature, 

barometric pressure, dissolved oxygen, alkalinity, turbidity, 

and discharge rates where applicable. Water samples 

collected were sent to the U.S. Geological Survey National 

Water Quality Laboratory and analyzed for major ions, 

trace elements, and nutrients. The National Water Quality 

Laboratory also analyzed selected samples for mercury and 

petroleum hydrocarbons. Additional samples at selected sites 

were collected and analyzed for cyanide, radiochemistry, and 

suspended sediment by U.S. Geological Survey contract labs. 

Fecal-indicator bacteria (Escherichia coli) were sampled for 

at selected sites as another indicator of water quality. Quality 

control for this study was achieved through proper training 

of field personnel, use of standard U.S. Geological Survey 

field and laboratory protocols, collection of sample blanks 

and replicates, and a thorough review of the water-quality 

analyses.

Measured field pH ranged from 6.0 to 8.8, within normal 

range for springs and rivers, at most sites. Concentrations 

of dissolved solids ranged from 48 to 8,680 mg/L and the 

majority of samples had concentrations of dissolved solids 

below 900 mg/L. Trace-element concentrations at most sites 

were at or near the laboratory reporting levels. The highest 

overall trace-element concentrations were found at U.S. 

Highway 160 Spring near Park Entrance to Mesa Verde 

National Park. Concentrations of uranium in samples at all 

sites ranged from below the detection limit to 55.7 μg/L. 

Water samples from selected sites were analyzed for total 

petroleum hydrocarbons and concentrations of total petroleum 

hydrocarbons were at or above the laboratory detection limit 

in samples at six National Park units. Ten sites were sampled 

for Escherichia coli and positive counts were found at 9 out of 

the ten sites, the highest colony counts were found at Chinle 

Creek at Chinle, AZ in Canyon de Chelly National Monument. 

Measured concentrations of dissolved ammonia, nitrite, and 

nitrate were at or near laboratory reporting levels at most 

sites; nitrate concentrations ranged from below the reporting 

limit (0.047 mg/L) to 9.77 mg/L. Samples that were analyzed 

for mercury had concentrations below or at the laboratory 

reporting level. Concentrations of cyanide were less than the 

laboratory reporting level for all samples except two, Spruce 

Tree House Spring in Mesa Verde National Park and Pine 

Tree Canyon Tinaja in Canyon de Chelly National Monument, 

which had average concentrations of .042 and .011 μg/L 

respectively. Gross alpha/beta radioactivity counts were 

below the U.S. Environmental Protection Agency maximum 

contaminant level except for samples from Casa Chiquita Well 

– Middle at Chaco Culture National Historical Park which 

averaged 35 pCi/L. Suspended-sediment concentrations were 

variable and ranged from 10 to 150,000 mg/L.

Introduction

The Level 1 Water-Quality Inventory is part of a 

nationwide program supported by the National Park Service 

(NPS) Water Resources Division (WRD) with the objective 

of developing baseline water-quality information for key 

water bodies at NPS units throughout the United States. 

This information is used to describe the current chemistry 

and quality of the waters and provide baseline information to 

monitor future trends. Key water bodies for Level 1 purposes 
are defined as those waters that are essential to the central 

cultural, historical, or natural resource management themes 

of the unit and (or) that provide habitats for threatened or 

endangered plants and animals (fig. 1 and table 1; Thomas, 

2003a and b). In 2004, the U.S. Geological Survey (USGS), 

in cooperation with the NPS, began studies of 13 NPS 

units within the Southern Colorado Plateau Inventory and 

Monitoring Network (SCPN). The basic chemical character 

and water quality of water bodies for 57 sites are described in 

this report.

The SCPN is one of 32 networks in the NPS Inventory 

and Monitoring Program. The SCPN is made up of 19 NPS 

units in northern Arizona, northern New Mexico, southwestern 

Colorado, and southeastern Utah. This Level 1 Water-Quality 

Inventory collected samples at 57 sites in 13 NPS SCPN units 

in water years 2005 and 2006. Each site was sampled three 

times when possible and sites included wells, springs, seeps, 

tinajas, rivers, a lake, and an irrigation ditch. The SCPN 

encompasses a broad geographical region and physiographic 

and climatic features vary widely from park to park (table 2).

All of the park units for this Level 1 Water-Quality 

Inventory lie within the Southern Colorado Plateau network 

and Arizona and New Mexico regions of the National 

Park Service Inventory and Monitoring Networks (fig. 1). 

SCPN park units include a total of almost 3 million acres 

of land area, span 232 miles from east to west, 135 miles 

from north to south, and cover 8,957 feet of vertical relief. 

Thirty-five percent of total SCPN park area is between 

2,500 and 3,300 feet above sea level, with some areas as 

low as 800 feet and others as high as 10,000 feet. More 

than 1.8 million acres are designated or proposed as 

wilderness areas.

The Colorado Plateau region is typified by aridity, 

relatively high temperatures with seasonal variations, 

and unpredictable seasonal, annual, and multi-decadal 

precipitation levels (Hereford and others, 2002; Noy-Meir, 

1973). The regional arid and semiarid conditions are 

important because of the impact that limited or irregular 

water availability has on ecosystem characteristics such as 

soil moisture, surface conditions, plant productivity, and 

faunal distribution. Rainfall and snowmelt on the Plateau 

are generally low, highly variable throughout the year, and 

occurs during infrequent, isolated events. Over 90 percent 

of annual precipitation received in the region is lost to 

evapotranspiration, with little surplus water and a scarcity of 

perennial streams (Fletcher and Bender, 1961). Water is an 

important limiting factor in biological processes throughout 

the Colorado Plateau region and an essential link between 

biotic and abiotic components of SCPN park ecosystems.

Purpose and Scope

This project was undertaken to provide NPS with waterquality information which will assist in the development of a 

long-term monitoring program and inform the park’s resource 

management on how best to manage each park and plan for 

the future. This report presents the results of sampling and 

analyses of surface-water and ground-water quality at 57 key 

water bodies in 13 of 19 NPS units in the SCPN during water 

years 2005 and 2006. Results of the water-quality inventory 

were compared to U.S. Environmental Protection Agency 

(USEPA) primary and secondary drinking water standards.

Water-quality data were collected during the spring, the 

summer, and the fall time periods. Brief descriptions of the 

data collection for each of the time periods follow.

March to June, 2005—Water samples were collected 

at 55 sites and analyzed for concentrations of major 

ions, trace elements, and nutrients. Bacteria samples 

were collected at 8 sites and gross alpha/beta samples 

were collected at 3 sites. Total petroleum hydrocarbons 

samples were collected at 10 sites.

July to September, 2005—Water samples were 

collected at 48 sites and analyzed for concentrations 

of major ions, trace elements, nutrients, mercury, and 

cyanide. Bacteria samples were collected at 4 sites 

and gross alpha/beta samples were collected at 3 sites. 

Total petroleum hydrocarbons samples were collected 

at 9 sites.

October to December, 2005—Water samples were 

collected at 51 sites and analyzed for concentrations 

of major ions, trace elements, nutrients, mercury, and 

cyanide. Bacteria samples were collected at 8 sites 

and gross alpha/beta samples were collected at 5 sites. 

Total petroleum hydrocarbons samples were collected 

at 10 sites.

Site Selection and Sampling

Fifty-seven sites at 13 NPS park units were included in 

this Level 1 baseline water-quality inventory (figs. 2a, b, c, d, 

e, f, g, h, i, j, k, and l). These sites were selected with input 

from NPS Natural Resource managers representing each 

park unit. Sites that were selected for inclusion in the Level 1 

inventory are essential to the central cultural, historical, and 

(or) natural resource management themes of the park units and 

may provide habitats for threatened and endangered plants and 

animals. Further details of each sampling site including a site 

description, hydrologic unit code, and source of geographic 

data can be found on a supplemental CD provided to NPS park 

mangers and available at http://az.water.usgs.gov.

Three sampling events were planned for each water body 

in order to capture seasonal variation in water chemistry. 

Sampling trips were scheduled at each site to include one 

sample each from the relatively wet spring-runoff and fall 

periods, and the relatively dry summer period. Some sites 

could not be sampled during all three time periods because 

the sites were dry. Forty-three of the 57 sites were sampled 

3 times, and 12 sites were sampled twice because of dry 

conditions, Cattail Spring in Mesa Verde National Park was 

only sampled once because it was dry during other times and 

the Ladera Arroyo at Petroglyph National Monument was 

never sampled because this arroyo did not have runoff suitable 

for sampling during the study period (figs. 1, 2i, 2k and 

table 1).

Following purging, water samples were filtered and collected 

from the sample line and bacterial samples were collected 

directly from the faucet.

Water samples collected from springs were collected 

as close to the source as possible. Teflon tubing was used to 

direct flow into a sampling bottle when necessary. When no 

flow was present, but water was pooled, a peristaltic pump was 

used to pump water directly through filters and into sample 

bottles. Field parameters were measured using individual 

hand-held meters.

Rivers, streams, and creeks were sampled using 

integrated samples when possible. Equal-width-increment 

or multiple-vertical-integrated samples were collected when 

possible. Dip or grab samples were collected at some sites 

because of the lack of water or there were safety concerns. 

Field parameters were measured with a Hydrolab minisonde 

multi-parameter probe for larger rivers and streams and 

individual hand-held meters were used on smaller streams 

and creeks.

Quality Control

Quality control for this study was maintained through 

the use of proper training of field personnel, use of standard 

USGS field and lab protocols, collection of sample blanks and 

replicates, and a thorough review of the analytical results. All 

USGS scientists involved with this study have participated in 

the USGS National Field Quality Assurance Program, which 

requires participants to successfully determine pH, specific 

conductance and alkalinity of reference samples supplied 

by the USGS Branch of Quality Systems. Field crews were 

trained in water-quality field methods by USGS personnel or 

through formal instruction at the USGS water-quality-field 

methods class.

Laboratory analyses were done at the NWQL using 

methods approved by the USGS or the USEPA. The detection 

level used by the NWQL for most analytes is the laboratory 

reporting level (LRL; Childress and others, 1999). This 

reporting level is determined through a statistical procedure 

designed to yield a false positive rate of less than one percent 

at the LRL (Childress and others, 1999), and is twice the longterm method detection level.

During three water-quality sampling rounds, replicate and 

field blank samples were collected to assure that collection 

methods and equipment did not yield any contamination. 

There were no blank samples taken during the first round of 

sampling (spring of 2005), but each subsequent round was 

accompanied with a blank sample. Analysis of the blank 

samples indicated no contamination (table 3). Trace amounts 

of zinc, 0.5 μg/L and 0.37 μg/L, were detected in both blank 

samples, but these detection levels are below the reporting 

level of 0.6 μg/L (table 3). Trace amounts of copper, 0.2 μg/L 

and 0.3 μg/L, were detected in both blank samples, but the 

detections were below the reporting limit of 0.4 μg/L.

Methods and Protocols

The current chemical character and water quality of the 

water bodies selected for this water-quality inventory were 

determined by collecting water samples and analyzing those 

samples for the following properties or constituents: (1) field 

measurements, (2) major ions, (3) nutrients, (4) trace elements, 

(5) uranium, (6) cyanide, and (7) mercury. Total petroleum 

hydrocarbons and gross alpha and gross beta radioactivity 

samples were collected at selected sites to assess risk to human 

activity. Fecal-indicator bacteria Escherichia coli (E. coli) 

samples were collected at selected sites were to determine 

whether activities such as grazing or recreation had affected 

the water quality.

Field measurements were done in accordance with 

standard USGS protocols documented in the USGS National 

Field Manual for the Collection of Water-Quality Data and in 

several USGS Techniques of Water-Resources Investigations 

Reports (Friedman and Erdmann, 1982; Britton and Greeson, 

1988; Koterba and others, 1995; Wilde and others, 1998a, 

b, c; Wilde and Radtke, 1998; Myers and Wilde, 1999; and 

Wilde and others, 1999). Field measurements include pH, 

specific conductance, temperature, barometric pressure, 

dissolved oxygen, alkalinity, turbidity, and discharge rates 

where applicable. Field alkalinities were determined using 

either incremental equivalence or Gran titration (Wilde and 

Radtke, 1998). Major ion, nutrient, trace element, cyanide, 

mercury, gross alpha and beta radioactivity and alkalinity 

samples were filtered through a 0.45-micron pore size filter 

and preserved according to sampling and analytical protocol. 

Laboratory analyses for samples other than cyanide and gross 

alpha and beta radioactivity were done at the USGS National 

Water Quality Laboratory (NWQL) according to techniques 

described in Fishman and Friedman (1989), Faires (1993), 

Fishman (1993), McLain (1993), Struzeski and others (1996), 

American Public Health Association (1998), Garbarino 

(1999), and Garbarino and Damrau (2001). Analyses of 

cyanide samples were done at Severn Trent Laboratories 

(STL) using USEPA method 335.3. Gross alpha and gross beta 

radioactivity analyses were done at Eberline Laboratories and 

followed the USEPA method 900.0.

Three major techniques were used for collecting 

water-quality samples and determining field parameters. 

Each technique was appropriate for the type of site being 

sampled: well, spring, or river. Water samples from wells were 

collected from a faucet near the wellhead and prior to any 

water treatment such as disinfection, softening, or filtration. 

Polyethylene tubing connected the faucet of a well to a splitter 

that directed water to a flow-through chamber, a sample line 

and an overflow line. A Hydrolab minisonde multi-parameter 

probe was used in conjunction with a closed flow-through 

chamber to determine field parameters. Wells were purged 

at least three well volumes and until field parameter stability 

criteria stabilized for two readings at 15 minute intervals; the 

pH within +/- 0.1 units, temperature +/- 0.2°Celcius, specific 

conductance ± 5 percent, and dissolved oxygen ± 0.3 mg/L.

20 Water-Quality Data for Selected National Park Units, Southern Colorado Plateau Network, WY 2005 and 2006
Replicate samples indicate the variability in the 

sampling and analytical processes. Two pairs of replicate 

samples were taken during each of the three water-quality 

sampling rounds, for a total of six replicate pairs (table 3). 

Replicate pairs were collected concurrently in individual 

containers using the same sampler. Previous Level 1 WaterQuality Inventory studies have used a criteria of 5 percent 

to evaluate validity of replicate samples (Brown, 2005). To 

conclude that a difference exists between a replicate sample 

and an environmental sample for the purpose of this study, 

the following two statements must be true; a) the percent 

difference between the two samples must be greater than 

5 percent and b) mathematically the average concentration of 

the analyte must be greater than 20 times the precision of the 

reported data in order to detect differences at increments of 

5 percent or smaller. For example, environmental and replicate 

samples from San Juan River near Clay Hills Crossing 

have chromium concentrations of 0.05 and 0.06 μg/L. The 

difference in concentrations between these two samples is 18 

percent and statement a) of the criteria is true. The precision 

of the reported data for chromium is 0.01 μg/L and the 

average of the concentrations of the analyte is 0.055 μg/L, 

therefore statement b) of the criteria is not true and there 

is no difference between the two samples. Using the above 

criteria that both statements must be true, there were only 5 

occurrences out of 220 possible pairs where replicate pairs 

were not in accordance (table 3). For major ions, one replicate 

sample pair had two analytes exceed the replicate accordance 

criteria. Environmental and replicate samples from Petroglyph 

Well 1 had magnesium values that differed by 5.2 percent and 

sodium values that differed by 15 percent (table 3). For traceelements, there were 3 occurrences where replicate samples 

exceeded our criteria. At NPS Canyon de Chelly Well No. 2 in 

Canyon de Chelly National Monument, nickel values differed 

by 11 percent and vanadium values differed by 60 percent 

between environmental and replicate samples (table 3). Nickel 

values between environmental and replicate samples for San 

Juan River near Clay Hills Crossing in Glen Canyon National 

Recreation Area also were greater than our criteria, 11 percent 

(table 3). Percentages were calculated by taking the difference 

between the two concentrations and dividing by the average 

of the environmental and replicate values. Trace-element 

variability was greatest at or near the laboratory reporting level 

for each element (table 3).

Water-Quality Data

Water quality and site description data collected through 

the Level 1 Water-Quality Inventory program will provide 

baseline information on water chemistry and quality to help 

facilitate the management of water resources in park units 

in the SCPN. The concentrations of dissolved constituents 

at the sites sampled for this study were compared to USEPA 

drinking water standards (USEPA, 2002; tables 4 and 5). 

Exceedances of USEPA drinking water standards at sites 

sampled for this study do not necessarily render them 

unsuitable for their respective water uses (figs. 2a–l and 

table 1). Samples were collected from wells that supply public 

water systems in Canyon de Chelly National Monument 

(fig. 2c), El Malpais National Monument (fig 2e), and 

El Morro National Monument (fig. 2f). Water-quality data 

collected for the Level 1 Water-Quality Inventory program 

complement regulatory samples collected by State or Tribal 

agencies for these sites.

Field pH values ranged from 6.0 to 8.8 and were within 

the USEPA secondary maximum contaminant level (SMCL) 

at most sites (table 4). The upper USEPA SMCL for pH of 8.5 

was exceeded at Tsaile Lake (fig. 2c and table 4). The lower 

USEPA SMCL for pH of 6.5 was exceeded at Alamo Springs 

Grazing Exclosure near Bandelier National Monument (fig. 2b 

and table 4) and U.S. Highway 160 Spring near Mesa Verde 

National Park (fig. 2i, table 4). Water temperatures varied 

seasonally at most springs and streams. Water temperatures 

were typically cool in spring, warm in summer and fall, and 

cold in winter. The lowest and highest water temperature range 

was measured at San Juan River near Clay Hills Crossing in 

Glen Canyon National Recreation Area (fig. 2g); 0.1°C in 

December 2005 and 31.2°C in July, 2005. Water temperatures 

at Hotel Spring in Grand Canyon National Park (fig. 2h) 

ranged from 4.3°C to 32.6°C (table 4).

All samples collected for this study were analyzed for 

dissolved concentrations of major cations and anions present 

in the water. The major-ion composition is in large part a 

reflection of the water-rock interactions that occur as water 

moves from a recharge area to the point at which it is sampled. 

Major-ion composition of water may vary in response to 

runoff in streams or recharge conditions in springs and wells. 

The major cations detected in water sampled during this 

study were calcium, magnesium, and sodium. Major anions 

detected in water samples were bicarbonate, sulfate, and 

chloride. Concentrations and compositions of the major ions 

in water sampled during the study varied widely from site to 

site (figs. 3 and 4).

The USEPA SMCL for sulfate of 250 mg/L was exceeded 

at multiple sites. High concentrations of sulfate were identified 

at Casa Chiquita Well – Middle (5,140 to 5,390 mg/L) in 

Chaco Culture National Historical Park; Last Chance Canyon 

at Burning Hills Road (1,680 to 2,080 mg/L) in Glen Canyon 

National Recreation Area; Cottonwood Creek North Rim 

Grand Canyon (1,950 to 2,410 mg/L) and Buckhorn Spring 

(1,910 to 2,070 mg/L) in Grand Canyon National Park; U.S. 

Highway 160 Spring near Park Entrance (3,320 mg/L), Cattail 

Spring (2,930 to 3,250 mg/L), and Echo Cliff Drainage Spring 

in Mesa Verde National Park; Main Yucca House Spring (809 

to 1,390 mg/L) in Mesa Verde National Park (figs. 2d, g, h, i 

and tables 4 and 5).

The USEPA’s MCL of 2.0 mg/L for fluoride was 

exceeded at U.S. Highway 160 Spring near Park Entrance 

to Mesa Verde National Park (fig. 2i) in all three samples 

collected at the site (table 4). Fluoride may be locally present 

in some geologic units and is used by some municipalities as a 

water additive to promote dental health.

Manganese was present in samples of water from many 

sites. The USEPA SMCL for manganese of 50 μg/L was 

exceeded at many sites in SCPN parks such as Canyon de 

Chelly National Monument, Chaco Culture National Historical 

Park, Glen Canyon National Recreation Area, Mesa Verde 

National Park, Petrified Forest National Park, Rainbow Bridge 

National Monument and Yucca House National Monument 

(tables 4 and 5).

Total dissolved-solids (TDS) concentrations ranged 

from 48 to 8,680 mg/L. Most values, however, fell into a 

much narrower range (fig. 3). Out of a total of 154 samples, 

116 yielded concentrations of less than 900 mg/L and 12 had 

concentrations greater than 3,600 mg/L. The USEPA SMCL 

of 500 mg/L for TDS was exceeded at twenty one sites 

(tables 4 and 5).

High concentrations of suspended sediment are 

possible indicators of activities such as grazing, mining, or 

agriculture, or can result from natural phenomena, such as 

wildfires or natural runoff. Samples from selected streams 

in Aztec Ruins National Monument (fig. 2a), Canyon de 

Chelly National Monument (fig 2c), Chaco Culture National 

Historical Park (fig. 2d), Glen Canyon National Recreation 

Area (fig. 2g), Mesa Verde National Park (fig. 2i), Petrified 

Forest National Park (fig. 2j), and Rainbow Bridge National 

Monument (fig. 2g) were analyzed for suspended-sediment 

concentrations. Measured concentrations ranged from 

10 to 150,000 mg/L (table 4). Samples with the greatest 

concentrations were from the Puerco River near Adamana, 

Ariz., in Petrified Forest National Park (fig. 2j).

Turbidity is a measure of water clarity affected by 

the proportion of suspended particles in the water column. 

Turbidity concentrations may be affected by biological 

activity, natural runoff processes, or by other near-stream or 

watershed disturbances (Davies-Colley and others, 2003). 

At sites in Aztec Ruins National Monument (fig. 2a), 

Bandelier National Monument (fig. 2b), Canyon de Chelly 

National Monument (fig. 2c), Chaco Culture National 

Historical Park (fig. 2d), El Morro National Monument 

(fig 2f), Glen Canyon National Recreation Area (fig. 2g), 

Mesa Verde National Park (fig. 2i), Petrified Forest National 

Park (fig. 2j), Petroglyph National Monument (fig. 2k), 

and Yucca House National Monument (fig. 2l) turbidity 

concentrations were greater than the USEPA MCL of 

5 NTU (nephelolometric turbidity units) (table 4). High 

concentrations of turbidity can raise water temperatures, 

reduce dissolved-oxygen concentrations and photosynthesis 

rates, and alter substrate habitat required for fish and aquatic 

macroinvertebrate species (USEPA, 2006c).

Trace-element concentrations at most sites were at 

or near LRLs. Elevated concentrations of aluminum were 

detected at several sites. The USEPA SMCL of 50 to 200 μg/L 

for aluminum was exceeded in samples from U.S. Highway 

160 Spring near Park Entrance to Mesa Verde National Park, 

Tsaile Creek below Tsaile Lake in Canyon de Chelly National 

Monument, Chaco Wash in Chaco Culture National Historical 

Park (figs. 2c, d, i, and tables 4 and 5). Concentrations of 

arsenic may occur from geologic sources as a result of 

erosion and runoff, but may also result from application of 

pesticides containing arsenic, or from electronics production 

wastes (Hem, 1985). The USEPA MCL for arsenic (10 μg/L) 

was exceeded in water samples from Chaco Wash in Chaco 

Culture National Historical Park, Santa Maria Spring in Grand 

Canyon National Park, and Petroglyph Well 1 in Petroglyph 

National Monument (figs. 2d, h, k, and table 4). Cadmium and 

beryllium are metals that naturally occur in some geologic 

deposits and are used for many industrial purposes. The 

USEPA MCL of 5 μg/L for cadmium and the USEPA MCL 

of 4 μg/L for beryllium were exceeded at U.S. Highway 160 

Spring near Park Entrance to Mesa Verde National Park, 

where concentrations for these constituents ranged from 

7.18 to 10.8 μg/L and 20.3 to 23.8 μg/L respectively (fig. 2i 

and tables 4 and 5).

Samples were collected for cyanide analysis at all sites. 

Concentrations of cyanide were less than the LRL of 0.01 

mg/L for all analyses with the exception of samples collected 

at Spruce Tree House Spring in Mesa Verde National Park 

and Pine Tree Canyon Tinaja in Canyon de Chelly National 

Monument (figs. 2c, i, and table 4). However, the analytical 

results did not exceed the USEPA MCL of 200 mg/L for 

cyanide. Cyanide concentrations in water can result from 

mining or industrial activities. Other potential sources of 

cyanide in the environment include land-fills, road salts, or 

chlorination treatment of some wastewaters (USEPA, 2006a).

Samples were collected for iron analysis at all sites. 

The USEPA SMCL for iron of 300 μg/L was exceeded at NPS 

Canyon De Chelly Well No. 2 in Canyon de Chelly National 

Monument, Puerco Well No. 2 in Petrified Forest National 

Park, and Main Yucca House Spring in Yucca House National 

Monument (figs. 2c, j, k, and table 4).

Selenium was sampled for at all sites and concentrations 

of selenium were low or near the LDL in most samples 

(table 4). Samples from the Historic Masonry Well - Middle in 

Chaco Culture National Historical Park (fig. 2d), Schmutz and 

Buckhorn Springs in Grand Canyon National Park (fig. 2h), 

and U.S. Highway 160 Spring near Park Entrance to Mesa 

Verde National Park (fig. 2i) approached but did not exceed 

the USEPA MCL of 50 μg/L for selenium. Selenium occurs in 

some geologic deposits and is used in a variety of industrial 

applications (USEPA, 2006c).

The expected range of uranium in natural waters is 

0.1 to 10 μg/L (Hem, 1985) and the USEPA MCL for uranium 

is 30 μg/L (table 5). Uranium can be present in water as a 

result of mining activity or at background levels derived from 

naturally occurring geologic sources. All sites were sampled 

Water-Quality Data  81
and analyzed for concentrations of uranium. The USEPA 

MCL for uranium was exceeded at seven out of eight sites 

sampled in Canyon de Chelly National Monument (fig. 

2c). At Many Cherry Spring in Canyon de Chelly National 

Monument (fig. 2c), the concentration of dissolved uranium 

was 32.5 μg/L, slightly above the USEPA MCL. At Casa 

Chiquita Well - Middle in Chaco Culture National Historical 

Park (fig. 2d), concentrations ranged from less than 0.16 to 

45.1 μg/L and Cattail Spring in Mesa Verde National Park 

(fig. 2i) had a dissolved uranium concentration of 55.7 μg/L 

(table 4).

Gross alpha and beta radioactivity samples were collected 

at seven sites. Gross alpha counts exceeded the USEPA MCL 

of 15 pCi/L in one sample from Casa Chiquita Well—Middle 

at Chaco Culture National Historical Park (fig. 2d and table 4).

Total petroleum hydrocarbons (TPHs) were collected 

from selected sites where potential impacts from vehicles, 

natural gas development, or other commercial or industrial 

activities was a concern. Concentrations of TPHs at or above 

the LDL of 2 mg/L were found in samples from Animas River 

at Aztec Ruins National Monument; Tsaile Lake, Tsaile Creek 

below Tsaile Lake, Tsaile Creek at Bare Rock Trail Crossing, 

and Chinle Wash below White House Ruins in Canyon de 

Chelly National Monument; Chaco Wash at Chaco Canyon 

National Monument, Historic Masonry Well – Middle, Casa 

Chiquita Well – Middle in Chaco Culture National Historical 

Park; San Juan River Near Clay Hills Crossing, Dirty Devil 

River above Poison Springs Wash near Hanksville, Utah in 

Glen Canyon National Recreation Area; Mancos River at 

Gaging Station in Mesa Verde National Park; and Puerco 

River near Adamana, AZ in Petrified Forest National Park 

(figs. 2a, c, d, g, I, j, and table 4). The USEPA has not 

established a contaminant standard for TPHs.

Bacteria can be an indicator of contamination from 

human or animal wastes (Hem, 1985; USEPA, 2002). 

Coliform bacteria are naturally present in the environment and 

feces, so the presence of total coliforms indicates only possible 

contamination. Fecal coliform and E. coli bacteria only come 

from warm-blooded animals fecal waste, so the presence of 

those bacteria indicates contamination from these sources 

(USEPA, 2002). E. coli bacteria colony counts were made at 

ten sites to determine the possible contamination from human 

or animal wastes. E. coli was detected in water samples from 

sites in Canyon de Chelly and Bandelier National Monuments 

(figs. 2b, c, and table 4). Samples collected during summer 

months had highest bacteria colony counts.

Nutrients samples were collected at all sites 

concentrations were measured at all sites as possible indicators 

of human activities. Measured concentrations of dissolved 

ammonia, nitrite, and nitrate were at or near LRLs at most 

sites (table 4). Concentrations of dissolved nitrogen ranged 

from below the LRL 0.047 mg/L to 9.77 mg/L. None of the 

sample analyses exceeded the USEPA MCL of 10 mg/L 

for nitrate (as N). Measured concentrations of dissolved 

orthophosphate were at or near LRL at almost every site. 

The highest concentrations were found at Chaco Wash at 

Chaco Culture National Historical Park (fig. 2d), where 

measured concentrations ranged from 0.19 to 0.57 mg/L.

Summary

The Level 1 Water-Quality Inventory is part of a 

nationwide program by the NPS, WRD to develop baseline 

water-quality information for key water bodies at NPS units 

throughout the United States. Fifty-seven sites were visited 

within the SCPN as a part of this Level 1 Water-Quality 

Inventory. To capture seasonal variation, sites were visited 

during three different sampling time periods. The results from 

the sample analysis were compared to USEPA primary and 

secondary drinking water standards.

Seasonal sampling events were completed from March 

to June, July to September, and October to December, 2005. 

Each sampling site included analysis for major ions, trace 

elements and nutrients. Some sites were analyzed for mercury, 

cyanide, total petroleum hydrocarbons, E. coli, gross alpha/

beta radioactivity and suspended-sediment concentrations.

 Measured field pH ranged from 6.0 to 8.8. 

Concentrations of dissolved solids ranged from 48 to 

8,680 mg/L and the majority of samples had concentrations 

of dissolved solids below 900 mg/L. Trace-element 

concentrations at most sites were at or near the LRL. The 

highest overall trace-element concentrations were found 

at U.S. Highway 160 Spring near Park Entrance to Mesa 

Verde National Park. Concentrations of uranium in samples 

at all sites ranged from below the LDL to 55.7 μg/L. Water 

samples from selected sites were analyzed for total petroleum 

hydrocarbons and concentrations were at or above the LDL 

in samples from six National Park units. Ten sites were 

sampled for E. coli and positive counts were found at nine 

out of the ten sites. The highest colony counts were found at 

Chinle Creek at Chinle, AZ in Canyon de Chelly National 

Monument. Measured concentrations of dissolved ammonia, 

nitrite, and nitrate were at or near LRLs at most sites; 

nitrate concentrations ranged from below the reporting limit 

(0.047 mg/L) to 9.77 mg/L. Samples analyzed for mercury 

had concentrations below or at the LRL. Concentrations of 

cyanide were less than the LRL for all samples except two, 

Spruce Tree House Spring in Mesa Verde National Park 

and Pine Tree Canyon Tinaja in Canyon de Chelly National 

Monument, which had average concentrations of .042 and 

.011 μg/L respectively. Gross alpha/beta radioactivity counts 

from Casa Chiquita Well – Middle at Chaco Culture National 

Historical Park exceeded the USEPA MCL and averaged 

35 pCi/L. Suspended-sediment concentrations were variable 

and ranged from 10 to 150,000 mg/L.
