Does MWRA water contain lead?
MWRA water is lead-free when it leaves the reservoirs. MWRA and local distribution pipes that carry the water to your community are made mostly of iron and steel, and do not add lead to water. However, lead can get into your tap water through pipes in the home, lead solder used in plumbing, and some brass fixtures. Corrosion or wearing away of lead based materials can add lead to tap water, especially if water sits for a long time in the pipes before use.
