Evaluation of increases in dissolved solids in ground water, Stovepipe Wells Hotel, Death Valley National Monument, California

Increases in dissolved solids have been monitored in two observation wells near Stovepipe Wells Hotel, Death Valley National Monument, California. One of the hotel 's supply wells delivers water to a reverse-osmosis treatment plant that produces the area 's potable water supply. Should water with increased dissolved solids reach the supply well, the costs of production of potable water will increase. The reverse-osmosis plant supply well is located about 0.4 mile south of one of the wells where increases have been monitored, and 0.8 mile southwest of the well where the most significant increases have been monitored. The direction of local ground-water movement is eastward, which reduces the probability of the supply well being affected. Honey mesquite, a phreatophyte located about 1.5 miles downgradient from the well where the most significant increases have been monitored, might be adversely affected should water with increased dissolved solids extend that far. Available data and data collected during this investigation do not indicate the source of the dissolved-solids increases. Continued ground-water-quality monitoring of existing wells and the installation of additional wells for water-quality monitoring would be necessary before the area affected by the increases, and the source and direction of movement of the water with increased dissolved solids, can be determined.

Open-File Report

Generalized thickness of the surficial deposits above the confining bed overlying the Floridan Aquifer, Southwest Florida Water Management District

This map report presents the thickness of the surficial deposits overlying the upper confining bed of the Floridan aquifer in the Southwest Florida Water Management District. The surficial deposits range in thickness from less than 25 feet in the western part of the district to greater than 250 feet in the eastern part. The surficial deposits include sand, clayey sand, shell, and shelly marl that occur in the Holocene sand, Pleistocene marine terrace sand, and unconsolidated parts of the Fort Thompson Formation, Caloosahatchee Marl, Alachua Formation, and Bone Valley Formation. Lithologic logs and information from quarries were used in conjunction with an unpublished map prepared during an earlier investigation to compile this map at 1:250,000 scale. (Kosco-USGS)

Generalized thickness of the confining bed overlying the Floridan Aquifer, Southwest Florida Water Management District

This map presents the thickness of the confining bed overlying the Floridan aquifer in the Southwest Florida Water Management District and adjacent areas. The bed separates the surficial aquifer from the underlying Floridan aquifer. Lithologic logs and information from quarries were used in conjunction with an unpublished map to compile this map at 1:250,000 scale. Units included in the confining bed are: clay, sandy clay and marl, undifferentiated with respect to age, the Hawthorn Formation, and the unconsolidated sections of the Tampa Limestone. (Kosco-USGS)

Water resources of the Santa Rosa Indian Reservation and vicinity, Riverside County, California

The Santa Rosa Indian Reservation is a 17-square-mile area located between the Santa Rosa and San Jacinto Mountains in south-central Riverside County, Calif. The source of water in most of the study area is precipitation on the three topographic subbasins that nearly surround the reservation. Precipitation averages about 12 inches annually (18,000 acre-feet per year), with 10 inches (15,000 acre-feet per year) of it returning to the air by evapotranspiration, 1 inch (1,500 acre-feet per year) running off from the area, and 1 inch (1,500 acre-feet per year) going to ground-water recharge. Local geology and the shape of the ground-water basin, as defined by a gravity survey, indicate that the area receives no ground-water inflow from outside the study area. Production of a dry-farm crop is planned for the 800-acre area west of Vandeventer Flat on the reservation's main section. Additional water supplies are needed for crop irrigation. At present (1979), water is obtained from a supply well that taps the saturated section of the sandy material overlying the basement complex of Cretaceous age or older. Existing data indicate that the aquifer may not yield large volumes of water to individual wells. A specific capacity of about 0.4 gallon per minute per foot of drawdown was measured at the supply well. Estimates of specific yield for the material encountered during the drilling of three wells and a test hole were 5 to 10 percent. The thickest section of the aquifer in the Vandeventer Flat area was outlined by a gravity survey. Test wells should provide information on thickness of the aquifer, aquifer properties, and potential well yield. Damming of area streams could also supply irrigation water. Average runoff totals about 1,500 acre-feet per year, with greater volumes lost during periods of heavy precipitation and flooding. Peak discharge from the central and southern subbasins totaled about 160 acre-feet per hour during the January-March period of 1978. Water-quality analyses for the supply well and five major springs indicate that the ground water is suitable for irrigation everywhere except at Sulphur Spring, where the percent sodium of 97 is above recommended maximum levels, and at Bull Canyon Spring, where water of 1,300 micromhos specific conductance is considered a high salinity hazard. The sulfate concentration of 290 milligrams per liter in Bull Canyon Spring is above the recommended maximum level for drinking water.
