Abstract: On June 22, 2000 the Environmental Protection Agency (EPA) proposed a new drinking water standard for arsenic. The proposed enforceable standard, or maximum contaminant level (MCL) for arsenic is 5 micrograms/Liter (μg/L) which would replace the existing standard of 50 μg/L. This report describes an estimate of the costs of compliance with a lower arsenic MCL in New Mexico that is based on cost estimates for community water systems affected by the proposed standard. Data on community water systems were provided by the New Mexico Environment Department (NMED) Drinking Water Bureau. Drinking water data for the pueblos is maintained by the NMED, so none of the pueblos were included in this analysis. The data provided by the NMED shows that 346 community water systems contain arsenic at or above the proposed MCL of 5 μg/L. For each of these communities, an estimate was prepared to determine the costs to construct, operate, and maintain four different treatment technologies.
