What is Lead?
Lead is a toxic heavy metal that leaches into drinking water from corroded pipes, solder, and plumbing fixtures, particularly in homes built before 1986. The EPA action level is 15 parts per billion, but no amount of lead in water is considered safe. Chronic exposure causes developmental delays in children and kidney damage in adults.
Who is most at risk in Stamford?
Lead matters most for infants, young children, pregnancy — harms developing brains — there is no safe level for children, and it crosses the placenta. The safe level for these groups is stricter than for a healthy adult.
How to remove Lead from your water
Install a point-of-use filter certified to NSF/ANSI Standard 53 for lead reduction, such as a reverse osmosis system or activated carbon block filter.
Run cold water for 30 seconds to 2 minutes before drinking or cooking, especially after water has sat in pipes for several hours, to flush lead-laden water from the service line.
Replace lead service lines and any brass fixtures or lead solder connections in your home plumbing, and test your water annually through a state-certified laboratory.
Never use hot tap water for drinking, cooking, or preparing baby formula, as hot water dissolves lead from plumbing more readily than cold water.
