Title: Water supply at Los Alamos during 1985: Progress report

Abstract

Well field operations during 1985 were satisfactory with municipal and industrial supplies consisting of 1587 x 10/sup 6/ gal from wells in three well fields and 37 x 10/sup 6/ gal from the gallery in Water Canyon. About 2.8 x 10/sup 6/ gal of water from Guaje Reservoir and 0.9 x 10/sup 6/ gal from Los Alamos Reservoir were used for irrigation; thus the total water usage in 1985 was about 1628 x 10/sup 6/ gal. Primary and secondary chemical quality of water in the distribution system is in compliance with federal regulations.

  • This report summarizes production and aquifer conditions for water wells in the Guaje, Pajarito, and Otowi Well Fields. These wells supplied all of the potable water used for municipal and some industrial purposes in Los Alamos County and the Los Alamos National Laboratory during 1993. The wells in the Los Alamos Well Field were transferred to San Ildefonso Pueblo in 1992. Four of the wells in the Los Alamos Well Field were plugged in 1993. One of the two new wells in the Otowi Well Field became operational in 1993. The spring gallery in Water Canyon supplied nonpotable water formore » industrial use, while surface water from the Los Alamos Reservoir was diverted for irrigation. In 1993 no water was used from the Guaje Reservoir. Due to the maintenance and operating cost of diverting water from the reservoirs, it is not economically feasible to continue their use for irrigation. This report fulfills some of the requirements of the Los Alamos Groundwater Protection Management Program by documenting use of the groundwater for water supply and providing information hydrologic characteristics of the main aquifer. This report is a joint effort between the Laboratory Water Quality and Hydrology Group and the Utilities Department of Johnson Controls World Services Inc. (JCI). The purpose of this report is to ensure a continuing historical record and to provide guidance for management of water resources in long-range planning for the water supply system. We have issued one summary report for the period of 1947 to 1971 and 22 annual reports that contain the results of our studies of these water supplies. An additional report summarized the hydrology of the main aquifer with reference to future development of groundwater supplies. A report was issued in 1988 that examined the status of wells and future water supply.« less
  • Production of potable municipal water supplies during 1994 totaled about 1,426.6 million gallons of wells in the Guaje, Pajarito, and Otowi Fields. The non-potable water supply for industrial use was about 11.6 million gallons from the spring gallery in Water Canyon. There was no water used for irrigation from Guaje or Los Alamos Reservoirs; thus, the total water usage in 1994 was about 1,438.2 million gallons. Pumps in Guaje Well 5 and Otowi Well 4 failed during the year and were not operational by the end of 1994. Water production resumed in Pajarito Well 3 in June. Wells in themore » Los Alamos Field, on Pueblo Land, were plugged and abandoned in 1992, or were transferred to San Ildefonso Pueblo. This report fulfills requirements which require the Laboratory to monitor and document groundwater conditions below Pajarito Plateau, and to protect the main aquifer from contamination associated with Laboratory operations by providing information on hydrologic characteristics of the main aquifer, including operating conditions of the municipal water supply system.« less
  • Production of potable municipal water supplies during 1995 totaled about 1,356.1 million gallons from wells in the Guaje and Pajarito well fields. Wells in the Otowi field were not operational during 1995. The nonpotable water supply for industrial use was about 1.6 million gallons from the spring gallery in Water Canyon, and another 1.6 million gallons from Los Alamos Reservoir was used for lawn irrigation. There was no water used from Guaje Reservoir in 1995. The total water usage in 1995 was about 1,359.3 million gallons. Groundwater pumpage during 1995 was the lowest on record since 1966.
  • Production of potable municipal water supplies during 1996 totaled about 1,368.1 million gallons from wells in the Guaje, Pajarito, and Otowi well fields. There was no water used from either the spring gallery in Water Canyon or from Guaje Reservoir during 1996. About 2.6 million gallons of water from Los Alamos Reservoir was used for lawn irrigation. The total water usage in 1996 was about 1,370.7 million gallons, or about 131 gallons per day per person living in Los Alamos County. Groundwater pumpage was up about 12.0 million gallons in 1996 compared with the pumpage in 1995. This report fulfillsmore » requirements specified in US Department of Energy (DOE) Order 5400.1 (Groundwater Protection Management Program), which requires the Los Alamos National Laboratory (LANL) to monitor and document groundwater conditions below Pajarito Plateau and to protect the regional aquifer from contamination associated with Laboratory operations. Furthermore, this report also fulfills special conditions by providing information on hydrologic characteristics of the regional aquifer, including operating conditions of the municipal water supply system.« less
  • The municipal and industrial water supply for Los Alamos for 1979 consisted of 1407 x 10/sup 6/ gal from wells in three fields and 44 x 10/sup 6/ gal from the gallery in Water Canyon. Another 0.2 x 10/sup 6/ gal of water were pumped to waste during the testing of Well LA-6. About 3.7 x 10/sup 6/ gal of water from Guaje Reservoir and 1.3 x 10/sup 6/ gal of water from Los Alamos Reservoir were used for irrigation; thus, the total use was about 1456 x 10/sup 6/ gal. Water level trends in the wells were as anticipatedmore » under current production practices. Well and distribution system rehabilitation should be continued. The rehabilitation of older wells and drilling and development of new wells are necessary to ensure an adequate and reliable water supply for municipal and industrial use at Los Alamos.« less
