HYDROLOGIC DATA FOR THE PUERCO RIVER BASIN, WESTERN NEW
MEXICO, OCTOBER 1,1991, THROUGH SEPTEMBER 30,1992
By Robert L. Gold and Dale R. Rankin
ABSTRACT
Hydrologic data collected during October 1, 1991, through September 30, 1992, in the Puerco River Basin, western New Mexico, are summarized in this report. The effects of uranium mining and a 1979 mill tailings spill, in combination with naturally occurring and potentially hazardous trace elements, have created a concern that surface water and ground water in the Puerco River Basin may be unsafe for irrigation, livestock watering, and domestic use; therefore, a data collection network was established to monitor the suitabililty of the water resources in the Puerco River Basin.
The data collection network consisted of one streamflow-gaging station, three water-well clusters, and nine streambed sites. The network is located along a reach of the Puerco River beginning near the confluence of the Puerco River and Pipeline Arroyo and ending approximately 9 miles upstream from the New Mexico-Arizona State line. Data tabulated and presented include mean daily discharge, ground-water hydrographs, water quality, and sediment chemistry and particle-size distribution.
INTRODUCTION
The Puerco River in western New Mexico drains an area that contains major uranium deposits (Wirt and others, 1991) and that has been subjected to uranium mining since the late 1950's. Mining activities, which include mine dewatering, have resulted in discharges to the Puerco River that contain radionuclides and other elements. In addition to these routine mine discharges, failure of a tailings pond at a uranium mill on July 16,1979, resulted in an estimated 94 million gallons of acidic wastewater (Millard and others, 1983) discharging into Pipeline Arroyo and consequently into the Puerco River. The effects of the uranium mining and the spill, in combination with naturally occurring and potentially hazardous trace elements, have created a concern that surface water and ground water in the Puerco River Basin may be unsafe for irrigation, livestock watering, and domestic use. To address these concerns, the U.S. Geological Survey, in cooperation with the Arizona Department of Environmental Quality and the New Mexico Environment Department, collected surface-water, ground-water, sediment, water- quality, and sediment-chemistry data to monitor the suitability of the water resources in the Puerco River Basin.
Purpose and Scope
This report describes the hydrologic data collected in the Puerco River Basin in western New Mexico by the U.S. Geological Survey during October 1,1991, through September 30,1992. Included in the report are a summary of the mean daily discharge, ground-water hydrographs, water quality, and sediment chemistry and particle-size distribution. Hydrologic data were
collected from a data collection network, established in 1988 as part of a prior study, consisting of one streamflow-gaging station, three water-well clusters, and nine streambed sites located along a reach of the Puerco River.
Study Area
The study area is a reach of the Puerco River in western New Mexico. The reach begins near the northern headwaters of the Puerco River in McKinley County near the confluence of the Puerco River and Pipeline Arroyo, then extends past the confluence with the South Fork of the Puerco River, through the city of Gallup, and terminates approximately 9 miles upstream from the New Mexico-Arizona State line. The locations of the study area and the data collection sites are shown in figure 1.
Previous Studies
The water resources of the Puerco River Basin have been studied by several Federal and State agencies. Most of these studies were conducted because of the possible effects of uranium deposits and uranium mining in the upper reaches of the Puerco River Basin on water supplies.
In response to the uranium mill tailings spill in 1979, the State of New Mexico Environment Department (NMED) (formerly called the New Mexico Environmental Improvement Division) conducted a program to monitor environmental conditions in the area around and downstream from the spill. Surface water, ground water, soils and sediment, air particulates, vegetation, gamma radiation, and livestock tissues were sampled. Using the results of NMED's sampling program and data collected by eight Federal and State agencies and four private contractors, NMED published a summary report (Millard and others, 1983). Millard and others (1983) analyzed the data to evaluate the impact of the spill on the environment and recommended future studies and means to limit adverse effects of the spill on inhabitants in the area.
The NMED, funded by the U.S. Environmental Protection Agency, compiled a regional assessment of the Grants Mineral Belt from 1978 to 1982. The mineral belt includes the New Mexico part of the Puerco River Basin. The purpose of the assessment was to evaluate the impacts of uranium mining on the quality of surface water and shallow ground water in the Grants Mineral Belt and to evaluate means to control water contamination resulting from uranium mining.
Gallaher and Gary (1986) listed water-quality data collected at various sites and analyses of those data. The report, in part, assessed water-quality conditions in the Puerco River Basin. Gallaher and Gary also included a series of recommendations concerning possible regulatory action to mitigate contamination of water supplies.
Van Metre and Gray (1991) expanded on the work of Gallaher and Gary (1986). Their study included analysis of additional chemical constituents, incorporation of data collected after mine dewaterings ended in February 1986, and evaluation of the relation of constituents to stream discharge and distance from the uranium mines. They also estimated total releases of uranium and gross alpha activity resulting from mine dewatering and the 1979 tailings-pond spill. A lumped-parameter digital computer model was used to investigate the path followed by the uranium that was released by the mines into the alluvial ground water.

A comprehensive review of historical water-quality data collected in the Puerco River Basin was conducted by the U.S. Geological Survey in the late 1980's. The study surveyed data collected by Federal and State agencies, as well as private companies. Data compiled from 1942 to 1988 were published in a report by Wirt and others (1991). A major part of the publication is an extensive bibliography of geologic, hydrologic, and water-quality investigations in the Puerco River Basin.
In 1985, the U.S. Geological Survey conducted a reconnaissance of the ground-water quality in the Puerco River Basin in cooperation with the Office of Navajo and Hopi Indian Relocation, U.S. Bureau of Indian Affairs. The study resulted from concern about the quality of surface water and ground water in the Puerco River Basin. These waters may serve as water supplies for those living on Navajo Tribal Trust Lands. The results of the reconnaissance study were reported by Webb and others (1987 a,b).
In 1988, the U.S. Geological Survey began a 4-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. A data collection network was established using streamflow-gaging stations and observation water wells to monitor water- quality trends in the basin. Some of the sites established for that network are the same sites used for collection of the data published in this report.
DESCRIPTION OF THE DATA COLLECTION NETWORK
The data collection network consisted of one streamflow-gaging station, three observation water-well clusters, and nine streambed sites. The network sites (fig. 1) were distributed along the reach of the Puerco River in New Mexico. The site name, site number, and types of data collected at each data collection site are listed in table 1 (all tables are in the back of the report).
The streamflow-gaging station on the Puerco River was installed and operated to determine changes in water quality and sediment discharge in response to storm runoff, and to record streamflow. Automatic sampling equipment collected water samples when the water level in the river reached a predetermined height. Sampling then continued at set time intervals until the runoff event had passed the gaging station. The water level was continuously monitored and recorded at 15-minute intervals during October 1, 1991, through September 30, 1992. The water level was used to compute streamflow, in cubic feet per second, in the river. Once these computations have been made, the resulting streamflow data can be compared with concurrent water-quality data to determine trends in water quality as related to streamflow.
The water-well clusters were constructed to collect data that could be used to determine changes in ground-water quality adjacent to the Puerco River. Water-quality samples were periodically collected from each well and analyzed. Water levels in three of the wells-two in the Windmill Cluster and one in the Manuelito Cluster-were continuously monitored from April to August 1992. A schematic representation of an idealized well cluster is shown in figure 2.

Streambed sites were established to collect data that characterize the chemistry and particle-size distribution of the Puerco River stream-channel sediments. Streambed samples were collected using a plunger-type device at nine preestablished stream cross sections. Each of these cross sections was sampled either March 31 or April 1,1992.
PRESENTATION OF DATA
Data tabulated and listed in this report are arranged by sampling station. Table 1 lists site names and numbers and the types of data collected. For the streamflow-gaging station, water- quality and sediment data are listed in table 2, and mean daily discharge values for October 1, 1991, through September 30,1992, are listed in table 3. For the three clusters of observation wells, water-quality constituents are listed in tables 4-12. Hydrographs of water-level data for April to August 1992 for wells equipped with recorders are shown in figures 3-5; in some cases the recorded data are incomplete because of recorder malfunction. Streambed analyses are listed in tables 13-21. Tables 2-21 also give detailed descriptions of each site location.
