Starting in January 2019, the City of Alamogordo Water Treatment Division will participate in the U.S. Environmental Protection Agency’s (EPA) Unregulated Contaminant Monitoring Rule (UCMR 4). Approximately 6,000 utilities nationwide will monitor unregulated contaminants for a year to help the EPA determine the occurrence of these contaminants in drinking water and whether or not they need to be regulated in the future. EPA uses the UCMR 4 to collect data for contaminants that are suspected to be present in drinking water and do not have health-based standards set under the Safe Drinking Water Act. We are committed to protecting public health and support EPA’s research.
UCMR 4 monitoring includes monitoring for a total of 30 chemical contaminants: 10 cyanotoxins (nine cyanotoxins and one cyanotoxin group) and 20 additional contaminants (two metals, eight pesticides plus one pesticide manufacturing byproduct, three haloacetic acid [HAA] groups, three alcohols, and three semivolatile organic chemicals [SVOCs]).
