Whether your water is from a municipal or a private water source, the only way to know if lead is in your water is to test for it. To test your drinking water for lead, contact a MECP licensed laboratory and then contact KFL&A Public Health for help with interpretation and corrective measures.
Flushing – lead levels increase in water as it stays in the pipes. Flush or run your water until it is cold, or at least one minute. Flush aerators occasionally to remove debris.
Filtration – install a filter that is certified for lead reduction and achieves National Sanitation Foundation or NSF standard 53, 58, or 62.
Replace or remove fixture – if faucets and valves are leaded-brass, replace them with lead-free material or if the fixture can not be replaced, do not use water from this faucet or valve for drinking or cooking.
