Community Water Systems Overview

Community water systems' (CWS) drinking water quality information presented here comes from the New Mexico Environment Department, Drinking Water Bureau, stewards of the Environmental Protection Agency Safe Drinking Water Information System (SDWIS), A CWS is a public water system (PWS) that serves year-round residents of a community, subdivision, or mobile home park that has at least 15 service connections or on average at least 25 residents. These CWSs are a subset of all New Mexico PWSs. Other water systems or private wells are not included here. The CWS drinking water quality data derived from the New Mexico SDWIS database are the ten contaminant analytes: arsenic, atrazine, Di-(2-ethyhexyl)phthalate (DEHP), disinfection by-products (haloacetic acids and total trihalomethanes), nitrate, tetrachloroethylene or perchloroethylene (PCE), radium (combined radium-226 and -228), and trichloroethylene (TCE), and uranium.
