The EPA recently announced a maximum contaminant level of 10 parts per billion for arsenic in drinking water.
Environmental Protection Agency (EPA) Administrator Christine Whitman recently announced a maximum contaminant level (MCL) of 10 parts per billion (ppb) for arsenic in drinking water. The new standard substantially reduces the acceptable level from the current 50 ppb and will help improve the safety of drinking water.
EPA estimates that the average annual household water bill may increase by $32 per year; however, the cost will be substantially higher for systems treating less than 3,300 people.
