What is the water system doing about lead in drinking water?

Answer: In accordance with the Lead and Copper Rule, your water system is required to test water collected from a number of households in your community for levels of lead and copper. Depending upon the number of people served by your water system and the levels of lead and copper found in sampling, your water system may also be required to install corrosion control treatment. Corrosion control treatment means systems must make drinking water less corrosive to the materials it comes into contact with on its way to consumer’s taps. Public education for lead is also triggered when tap samples exceed the lead action level of 15 µg/l. If corrosion control treatment is not effective at reducing lead levels, your water system may be required to replace lead service lines, if present, that connect some households in your community to water mains.
