What is lead and why is it a problem?
Lead is a common metal found in air, soil, household dust, and water. It is also found in consumer products, some types of food, pottery, pewter and lead-based paint. If inhaled or swallowed, lead can build up in the body. If too much lead enters the body, it can damage the brain, nervous system, red blood cells, and kidneys. Children, infants, and pregnant women are at greater risk.
How does lead get into household water?
The most likely sources of lead in your household water are lead pipes, lead solder, or brass fixtures in your plumbing. Lead water services were installed in Saint Paul homes built before 1926 and in some homes built between 1942 and 1947. Usually, lead gets into your water after it leaves your local treatment plant.
