Lead water pipes can sometimes be found in older homes. Drinking water faucets manufactured before 2014 were allowed to contain up to 8% lead. This lead can sometimes find its way into our drinking water.
Lead found in drinking water is soluble or particulate. Soluble lead is lead that is dissolved in water. Particulate lead is small pieces of lead from lead-containing material. Either type of lead can get into your drinking water when pipes or faucets containing lead begin to break down or dissolve. The amount of lead that can end up in drinking water depends on:
- Water chemistry (what is in the water)
- Contact with lead-containing items (if it passes through lead plumbing or fixtures)
- Water use (how often and in what amount water runs through plumbing and fixtures)
- Construction or plumbing repairs in the street or home (particulate lead can be released)
