Housing Age Profile

A citywide median of 1995 for construction says little about any single address in Mountain View. Homes built before 1986, when federal amendments restricted the lead content allowed in new pipe, solder and flux, may contain plumbing materials with more lead, and later renovations may have replaced them. An inspection of the plumbing can identify the materials, and sending a tap water sample to an accredited laboratory measures lead.

Most homes in Mountain View were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
