NM Geology Studies Arsenic in Groundwater, July 2, 2001

SOCORRO, N.M., July 2, 2001 -- One of the current issues of New Mexico Geology focuses on an investigation of the levels and distribution of arsenic in ground water in the Socorro Basin.

"Arsenic in ground water in the Socorro Basin, New Mexico" details a recent study made by Lynn Brandvold of the New Mexico Bureau of Geology and Mineral Resources (NMBGMR), which examines the presence of high concentrations of arsenic in the Socorro ground-water basin, along the Rio Grande from San Acacia to San Marcial. Physical and chemical parameters, listed in three different tables, are summarized on a well-by-well basis for the 74 water wells included in the study.

Other articles in the periodical also provide a regulatory summary of the new arsenic standard, the cost of compliance with a new drinking water standard, and an evaluation of the costs and benefits of a lower arsenic maximum contaminant level for community water systems.

New Mexico Geology is published quarterly by NMBGMR, a service division of New Mexico Tech. A subscription to the award-winning journal costs $10 per year or $18 for two years. Individual issues may be purchased for $2.50 each.
