In a notice released yesterday, the Doña Ana Mutual Domestic Water Consumers Association received a drinking water violation after failing to notify customers about a sighting of uranium in their products. The violation was originally issued after uranium levels rose above the federal drinking water standard earlier this year under what is called the "Public Notice Rule." Federal regulations require public water systems to notify customers within a specific timeframe whenever certain drinking water violations occur, so that residents are informed about potential health problems in their water. The Doña Ana Mutual Domestic Water Consumers Association released a further detailed statement involving this matter, as well:Our water system recently violated a drinking water standard. We routinely monitor for the presence of drinking water contaminants.
