Groundwater, surface–water, and water-chemistry data, Black Mesa area, northeastern Arizona—2007-2008

Abstract

Dissolved-solids, chloride, and sulfate concentrations increased at Moenkopi School Spring during the more than 12 years of record at that site. Concentrations of dissolved solids, chloride, and sulfate at Pasture Canyon Spring have not varied much since the early 1980's, and there is no trend in those data.

Groundwater, surface-water, and water-chemistry data, Black Mesa area, northeastern Arizona—2009–10

“…A. Median winter flow for November, December, January, February, 1977-2009 Table 16. Physical properties and chemical analyses of water samples from selected industrial and municipal wells completed in the N aquifer, Black Mesa area, northeastern Arizona, 2010.…”

“…2 Does not include withdrawals from the wells equipped with windmills. 3 Includes estimated pumpage 1965-73 and metered pumpage 1974-79 at Tuba City; metered pumpage at Kayenta and estimated pumpage at Chilchinbito, Rough Rock, Piñon, Keams Canyon, and Kykotsmovi before 1980; metered and estimated pumpage furnished by the Navajo Tribal Utility Authority and the Bureau of Indian Affairs and collected by the U.S. Geological Survey, 1980-85; and metered pumpage furnished by the Navajo Tribal Utility Authority, the Bureau of Indian Affairs, various Hopi Village Administrations, and the U.S. Geological Survey, 1986-2009. Kister and Hatchett (1963) made the first comprehensive evaluation of the chemistry of water collected from wells and springs in the Black Mesa area.…”
