Title Are Some California Residents Exposed to Lead-Tainted Drinking Water?
Introduction LA Testing provides analytical services and sampling supplies to identify lead hazards in water, air, dust and bulk materials.

Garden Grove, CA, August 26th, 2015

Earlier this year, the NBC4 I-Team broadcasted an investigative report about possible lead-tainted drinking water at schools in the Los Angeles area. It was a follow-up to a report done by the same station seven years earlier that had found old pipes and drinking fountains that could be exposing children and faculty to lead poisoning risks.
These same exposure risks can also occur in homes and other buildings across California. According to the U.S. Environmental Protection Agency (EPA), “Although the main sources of exposure to lead are ingesting paint chips and inhaling dust, EPA estimates that 20 percent or more of human exposure to lead may come from lead in drinking water. Infants who consume mostly mixed formula can receive 40 to 60 percent of their exposure to lead from drinking water.”

Lead was sometimes used in household plumbing materials or in water service lines that brought water from the main to the home or building. A prohibition on lead in plumbing materials has been in effect since 1986. The lead ban (1986 Amendments of the Safe Drinking Water Act) states that only “lead free” pipe, solder or flux may be used in the installation or repair of public water systems, or any plumbing in a residential or non-residential facility providing water for human consumption, which is connected to a public water system. However, even “lead free” plumbing may contain traces of lead.
“Even though most water systems do test for lead as a regular part of their monitoring program, these tests only give a system-wide picture and do not reflect conditions at a specific drinking water outlet in a person’s home, office or other location,” said Michael Chapman, Laboratory Manager at LA Testing’s Garden Grove facility. “Homes and properties built before 1986 are more likely to have lead pipes, fixtures and solder. The EPA reports that the most common problem is with brass or chrome-plated brass faucets and fixtures which can leach significant amounts of lead into the water, especially hot water.”
California residents concerned about the possibility of lead in their drinking water can turn to LA Testing for all of the sampling supplies and testing services needed. LA Testing also recently sponsored an educational video about lead in drinking water that can be seen at:
