HISTORICAL WATER-QUALITY DATA, PUERCO RIVER BASIN, ARIZONA AND NEW MEXICO By Laurie Wirt, Peter C. Van Metre, and Barbara Favor

ABSTRACT

In June 1988, the U.S. Geological Survey began a 5-year study of the occurrence and movement of radionuclides and other trace metals in ground water and surface water in the Puerco River basin in northeastern Arizona and northwestern New Mexico. Radionuclides and other trace metals occur naturally in water, rock, and sediments in the region; however, mining operations have enhanced their release to the Puerco River through discharges of mine effluents. Additionally, in 1979, the failure of a tailings-pond dike resulted in the largest known single release of water contaminated by uranium tailings in the United States. This report presents selected historical water-quality data and a bibliography of selected references on the geology, hydrology, and water quality of the Puerco River basin. Historical water-quality data for surface water, ground water, and uranium-mine discharges for water years 1942 through 1988 were compiled from information from Federal, State, and local agencies.

INTRODUCTION

In June 1988, the U.S. Geological Survey (USGS) began a 5-year study of the occurrence and movement of radionuclides and other trace metals in ground water and surface water in the Puerco River basin in northeastern Arizona and northwestern New Mexico (fig. 1). The Puerco River drains the west flank of the Chuska Mountains and the western part of the Grants Mineral Belt in New Mexico. Uranium was mined near Church Rock in the 1950's until 1962 and from 1967 to 1986. Uranium milling also took place from 1977 to 1986. Radionuclides and other trace metals occur naturally in water, rock, and sediments throughout the region; however, mining operations enhanced their release to the Puerco River through discharge of mine-dewatering effluents. Additionally, the failure of a tailings-pond dike near the Puerco River headwaters in 1979 resulted in the largest known single release of water contaminated by uranium tailings in the United States. Since the tailings-pond dike failure in 1979, concern has increased about the quality of surface water and ground water in the Puerco River basin, particularly in the Navajo Tribal Trust Lands referred to as the New Lands area near Chambers, Arizona (fig. 1). In 1980, an amendment to the Relocation Act (Public Law 93-531) permitted the addition of about 400,000 acres of land to the Navajo Reservation in two areas in 1 30' 108°

Figure 1.--Location of study area, Arizona and New Mexico. The larger area is south of Chambers, Arizona, and currently consists of 350,000 acres (fig. 1), but will eventually include 365,000 acres (Christopher Bavasi, Director, Office of Navajo and Hopi Indian Relocation, oral commun., 1990). The smaller area consists of 35,000 acres in New Mexico (not shown on map) and is known as the Paragon Resources Ranch (David Shaw-Serdar, Office of Navajo and Hopi Indian Relocation, oral commun., 1990). The land is being used by the Navajo people who are relocating from the former Navajo and Hopi Joint Use Area, which is now a part of the Hopi Reservation (Paul Tessler, Legal Counsel for the Office of Navajo and Hopi Indian Relocation, oral commun., 1989). As of June 1990, 149 families had relocated in the New Lands area (Christopher Bavasi, Director, Office of Navajo and Hopi Indian Relocation, oral commun., 1990), and the population is expected to increase from a pre-1983 population of approximately 875 to about 3,000 people as a result of the relocation. Ground-water use is expected to change from mainly livestock supply to domestic and public supplies as a result of the increase in population. In 1985, the Office of Navajo and Hopi Indian Relocation requested that the USGS study the distribution of radionuclides in water resources in the basin. Webb and others (1987a, b) made a reconnaissance- level study of the ground-water quality in the Puerco River basin and determined that radionuclide activities in 5 of 14 wells were at or above the maximum contaminant level for the State of Arizona of 15 pCi/L (picocuries per liter) of gross alpha minus the sum of activity of uranium and radon (McClennan, 1984) and the U.S. Environmental Protection Agency (1986a). The present, more detailed study of quality and hydrology of surface water and ground water began in 1988. This study is being done in cooperation with the Office of Navajo and Hopi Indian Relocation (ONHIR), U.S. Bureau of Indian Affairs (BIA), the Navajo Nation, Arizona Department of Water Resources (ADWR), Arizona Department of Environmental Quality (ADEQ), and New Mexico Environmental Improvement Division (NMEID).

Purpose and Scope

The purpose of this report is to present (1) selected historical water-quality data for the Puerco River basin that were collected prior to October 1988 and (2) a bibliography of selected references on the geology, hydrology, and water quality of the Puerco River basin. Chemical analyses have been grouped into three types surface-water data, ground-water data, and data that specifically concern uranium-mine discharges. In the interest of completeness, some previously published data and data from other agencies are included. The report includes selected data from 1942 through the 1988 water year, which ended on September 30, 1988.

Me 7 ? -Numbering Systems

The well numbers used by the Geological Survey in Arizona are in accordance with the Bureau of Land Management's system of land sub­ division. The land survey in Arizona is based on the Gila and Salt River Meridian and Base Line, which divide the State into four quadrants (fig. 2). These quadrants are designated counterclockwise by the capital letters, A, B, C, and D. All land north and east of the point of origin is in A quadrant, that north and west in B quadrant, that south and west in C quadrant, and that south and east in D quadrant. The first digit of a well number indicates the township, the second the range, and the third the section in which the well is situated. The lower case letters a, 6, c, and d after the section number indicate the well location within the section. The first letter denotes a particular 160-acre tract, the second the 40-acre tract, and the third the 10-acre tract. These letters also are assigned in a counterclockwise direction, beginning in the northeast quarter. If the location is known within the 10-acre tract, three lowercase letters are shown in the well number. In the example shown, well number (A-19-28)23dcd designates the well as being in the SEJSWJSEJ sec. 23, T. 19 N., R. 28 W. Where more than one well is within a 10-acre tract, consecutive numbers beginning with 1 are added as suffixes. In New Mexico, the State identification number locates the well site to the nearest 2.5-acre tract in the land network (fig. 3). The site number is divided into four segments. The first segment denotes the township north or south of the New Mexico Base Line; the second segment denotes the range east or west of the New Mexico Principal Meridian; the third segment denotes the section. The fourth segment, consisting of four digits, denotes the 160-, 40-, 10-, and 2.5-acre tracts, respectively, in which the site is situated. For this purpose, the section is divided into four quarters, numbered 1, 2, 3, and 4, in the normal reading order, for the northwest, northeast, southwest, and southeast quarters, respectively. The first digit of the fourth segment gives the quarter section, which is a tract of 160 acres. Similarly, the quarter section is divided into four 40-acre tracts numbered in the same manner; the second digit denotes the 40-acre tract. The 40-acre tract is divided into four 10-acre tracts; the third digit denotes the 10-acre tract. The 10-acre tract is divided into four 2.5-acre tracts; the fourth digit denotes the 2.5-acre tract. Thus, site T. 16 N., R. 16 W., 17.2114 is in the NE*NW*NW*SEi, section 17, Township 16 North, Range 16 West, second 160-acre tract, first 40-acre tract, first 10-acre tract, and fourth 2.5-acre tract. If the site cannot be located accurately within a 2.5-acre tract, the fourth digit is absent; if it cannot be located accurately within a 10-acre tract, the third digit is absent; if it cannot be located accurately within a 40-acre tract, the second, third, and fourth digits are absent. If the site cannot be located more closely than a section, the entire fourth segment of the number is omitted (Gallaher and Cary, 1986). WELL(A-19-28)23dcd R.28 W.

In the Navajo Reservation, where public land surveys have not been made (fig. 4), the local identifier is a field number that consists of three parts. The first part is formed from the BIA district number. The second part is the 15-minute quadrangle number also assigned by the BIA. The third part is the quadrangle location number and indicates the position of a site within a 15-minute quadrangle and consists of two parts. The first part is the distance in miles west of the northeast corner of the quadrangle, and the second part is the distance in miles south of the northeast corner of the quadrangle (fig. 5). The letter A at the end of the quadrangle location number means an approximate location.

Physical Setting

The Puerco River basin drains about 3,000 mi 2 of the southeastern part of the Colorado Plateau (fig. 1). The headwaters of the Puerco River are in northwestern New Mexico, north of the Zuni Mountains and west of the Chuska Mountains. The river flows for a total of 140 mi southwestward through Gall up, New Mexico, then west-southwestward to join the Little Colorado River east of Hoi brook, Arizona. The Puerco River is ephemeral along most of its length and is characterized by long periods of no flow. Most runoff occurs in response to spring snowmelt and to brief, intense summer thunderstorms. Since the 1950's, flow in some reaches of the Puerco River has become perennial as a result of effluent discharge from uranium mines and from the sewage-treatment plant at Gall up, New Mexico (Gallaher and Cary, 1986; Perkins and Goad, 1980).

Geologic Setting

Bedrock in the Puerco River basin consists of folded Paleozoic and Mesozoic sedimentary rocks that dip slightly to the northeast (Cooley and others, 1969). Steeply dipping fault zones that trend north and south displace these rocks. In New Mexico (fig. 1), the basin follows the Gall up Sag, a synclinal depression that lies between the Defiance and Zuni Uplifts to the north and southeast (Hilpert, 1969). Younger rocks of Tertiary and Quaternary age, including the Tertiary Bidahochi Formation, generally are undeformed. Major uranium and minor coal deposits are in the Jurassic Morrison Formation to the east and northwest of Gallup (Hackman and Olson, 1977). Uranium minerals also occur in the Petrified Forest Member of the Triassic Chinle Formation in the west half of the basin. Natural erosion of bedrock that contains uranium and other radionucl ides provides the source material for background radiation in regional water resources and sediments (Weimer and others, 1981). The unconsol idated channel deposits and stream-terrace sediments are Quaternary and Tertiary in age (Harrell and Eckel, 1939). 1100 30' 110° 30' 109° 30' 108° 36 fa ^-v" 93 \ 00 91 90 \ 8JS\'^ 88 87 / sb 85 HOPI 1 DISTRICT 10 I v /"' ^y^ \ DISTRICT J INDIAN . _ ^ ^ ) ' 1 ) \ 14 RESERVAT ION /-! i j J A y ; 113 / il2J . 111 110 109 ' ^e ( 107 106 / ^JQ5 104 L-r-^ Window Roc NAVAJO / (/ ' _._ v._ :> _ . _ ' \X^ jsi r- C i "X/*' s INDIAN / \ ._^' ~"' J (l .X" f RESERVATION /D ISTRldT Gailup 30 ___ i _ \ y 129 128J 127 126 1^5 18 / 121 /-'

Hydrogeologic Setting

The alluvial aquifer beneath the streambed of the Puerco River consists of interbedded gravel, sand, silt, and clay (Mann and Nemecek, 1983). The lateral extent of the alluvial aquifer varies from only a few feet at bedrock exposures to several miles wide in parts of the lower part of the Puerco River basin. The thickness of the aquifer is not well known, but monitor wells drilled at three sites in a 14-mile reach of the Puerco River near Sanders encountered bedrock at 75, 102, and 140 ft. A monitor well drilled to a depth of 193 ft at a nearby fourth site did not encounter bedrock.

Prior to the late 1950's, streamflow in the Puerco River was the result of runoff from thunderstorms, snowmelt, and small quantities of flow from local springs. Since uranium mining began in the Puerco River headwaters, water has been pumped from deep mine shafts and discharged directly to Pipeline Arroyo, which is a headwater tributary of the Puerco River. Water was pumped from the Church Rock Mine at a rate of less than 1 ft3/s from 1960 until the mine was abandoned in 1963 (Hearne, 1977; Perkins and Goad, 1980). Mining resumed in 1967 and, from 1967 to 1986, dewatering discharges ranged from about 5 to 13 ft3/s (Gallaher and Cary, 1986; New Mexico Water Quality Control Commission, 1988; Perkins and Goad, 1980). Effluent discharge from the sewage-treatment plant in Gall up and mine dewatering from the mines near Church Rock resulted in perennial flow in the Puerco River as far downstream as 15 mi west of the New Mexico- Arizona State line (Arizona Department of Health Services, 1983). Although mine dewatering ceased In 1986, discharges from the sewage-treatment facility In Gall up maintained perennial flow from Gall up to beyond the State line of Arizona and New Mexico. In 1958, the City of Gall up began operation of the sewage-treatment facility and has gradually Increased effluent discharges. As of 1989, the facility discharges an average of 4.0 ft s/s to the Puerco River (Albert Jackson, Wastewater System Superintendent, Water Maintenance and Repair, City of Gallup, New Mexico, oral commun., 1989).

The Puerco River contains unusually large concentrations of suspended sediment. In the study period for this report, concentrations of suspended sediment ranged from 474 to 111,000 mg/L. The largest concentration measured to date by the USGS, however, was about 300,000 mg/L on August 1, 1989, at the streamflow-gaging station at Chambers. Because much of the radionuclide activity in the Puerco River is associated with the suspended phase, large variations in total activity generally are associated with fluctuations in suspended-sediment concentrations (Gallaher and Cary, 1986). Except for samples collected during the tailings-pond spill in 1979, measured gross alpha plus gross beta activities in unfiltered samples range from near zero to about 6,700 pCi/L.

In most places, the alluvial aquifer of the Puerco River is underlain by the nearly impermeable siltstone of the Chinle Formation, which impedes downward movement of water into underlying strata. In some areas, such as in tributary channels to the Puerco River and near Navajo, Arizona, the alluvium overlies the permeable strata of the Bidahochi Formation or the sandstone beds of the Chinle Formation, and the alluvium is hydraulically connected to the underlying unit. Most wells that penetrate these formations provide water for livestock and domestic supplies; chemical quality is suitable for most uses (Mann and Nemecek, 1983).

Sources of Data

Data for this report were compiled by the U.S. Geological Survey from information from Federal, State, and local agencies (table 1) and include data from the Storage and Retrieval (STORET) System of the U.S. Environmental Protection Agency (EPA). The STORET system contains water-quality data for surface water and ground water that have been submitted by participating Federal and State agencies. Analyses are identified by source with a code in the agency column of each table, and those codes are explained in table 1. Some data have been published in other articles and reports. Data that have been deliberately omitted include (1) data from the EPA Superfund investigation of the Church Rock Mine, (2) data from the City of Gallup water-supply well records and sewage-treatment records, and (3) data from the National Uranium Resource Evaluation. Data from those sources were considered too voluminous to publish here but can be obtained readily from the appropriate agency. 10 Table 1.--Contributing agencies

FEDERAL AND STATE CRITERIA FOR MAXIMUM CONTAMINANT LEVELS

Radionuclides of natural origin and those released by mining operations include uranium, thorium, and their daughter products. Spontaneous transformations in the nuclei cause the emission of alpha and beta particles and, to a lesser extent, gamma rays (Faure, 1977). Although the amount of a radionuclide in a given volume of water can be reported as mass concentration, it usually is presented as an activity in units of picocuries per liter (pCi/L). Radionuclides with short half-lives produce greater amounts of radioactivity than do radionuclides with long half-lives for the same concentration. 11 Radionuclides in the uranium-238 decay series are harmful to human health in large quantities because of a combination of radiotoxicity and chemical toxicity. Different radionuclides exhibit varying degrees of both radiotoxicity and chemical toxicity. Radiotoxicity is the damaging effect of ionizing radiation on tissues. For example, radium, which is one of the most toxic elements, is highly radioactive and tends to accumulate in the bone (Davis and DeWiest, 1966). In contrast, no studies have found the radiotoxic effects of uranium to be significant. Although uranium is a radioactive element, its radiotoxic effects are insignificant because of the long half-lives of its isotopes and subsequent low activity. Uranium toxicity is due primarily to the chemical effects of its aqueous hexavalent ions on the kidneys (Wrenn and others, 1987).

The maximum contaminant levels applicable to the Puerco River basin in Arizona are based on regulations of the State of Arizona and ERA (table 2). The amount of radium-226 in water supplies forms a basis for monitoring natural radionuclides in drinking-water supplies in the United States (fig. 6). On the basis of radiotoxicity, the ERA primary maximum contaminant level is 5.0 pCi/L for total radium-226 plus radium-228. The maximum contaminant level for gross alpha minus the sum of uranium and radon activity is 15 pCi/L, and the maximum contaminant level for total gross beta activity is 50 pCi/L (table 2 and fig. 6). A maximum contaminant level has not been established for uranium in drinking water. On the basis of chemical toxicity, the recommended limit for uranium is 0.035 mg/L (milligrams per liter; Lappenbusch and Cothern, 1985). State of Arizona (1977) regulations also require that if the identity or concentration of any radionuclide in a mixture of radionuclides in water is unknown, the limiting value for the regulation is 30 pCi/L of gross alpha plus gross beta activity (table 2).

Uranium-mine discharges in New Mexico are subject to several Federal and State laws and regulations. No single statute addresses all significant water-quality effects resulting from uranium mining (Gallaher and Gary, 1986). Ground-water regulations for domestic water supply (New Mexico Water Quality Control Commission, 1985) specify a maximum level of 30 pCi/L for total radium-226 plus radium-228. The limit for natural uranium in ground water for domestic water supply is 5.0 mg/L. Regulations for New Mexico (New Mexico Environmental Improvement Board, 1985), which apply to water-supply systems regardless of source, specify a maximum total radium activity of 5 pCi/L and a maximum gross alpha minus the sum of uranium and radon activity of 15 pCi/L.

Uranium minewater discharges are exempt from ERA and State regulations. Uranium minewater discharges, however, are subject to Section 402 of the Clean Water Act, which establishes the National Pollutant Discharge Elimination System (NPDES) that regulates discharges of pollutants into navigable waters by permit (Gallaher and Gary, 1986). The courts have broadly construed navigable waters to include tributaries of perennial rivers, including intermittent streams flowing through normally dry arroyos. NPDES permit conditions for mines in the Church Rock District are shown in table 3. 12 Table 2.--Maximum contaminant levels for selected constituents in water. Puerco River basin. Arizona

EXPLANATION OF ILLUSTRATIONS AND TABLES Sampling sites for surface water and ground water are shown on plates 1 and 2, respectively. Each site is identified with a unique integer. That integer is listed in tables 4 and 5 along with location and identification information. Information on surface-water sites includes map-identification number from plate 1, unique site-identification number, site name, site type, and remarks (table 4). Information on ground-water sites includes map-identification number from plate 2, unique site-identification number, local well number, site type, and remarks (table 5). Chemical analyses are grouped into three categories surface- water data, ground-water data, and data that specifically concern mine discharges. The water-quality data for mine discharges are in tables 6-11, and the surface-water and ground-water data are in the section entitled "Historical Water-Quality Data" at the end of this report. All data of the USGS in this report were collected using standard methods of the USGS described by Kister and Garrett (1984). Data from other agencies may have been collected using other methods of collecting, different analytical techniques, and (or) other methods of reporting. Many of the methods used by the USGS and other agencies may have changed or have been refined with time. Caution is recommended when making comparisons between quality-of-water data over a long period of time even if those data are from the same agency. 15

Table 3.--Permit conditions for the National Pollutant Discharge Elimination System for uranium nrinewater discharges. Church Rock Mining District [* indicates that although the permit does not specify a numeric limitation, monitoring and reporting are required (table from Gallaher and Gary, 1966). Units of measure are reported as published in Gallaher and Gary, 1986.
