Housing Age Profile

Copper plumbing joined with lead solder was standard practice through the mid-1980s - a design choice that federal regulators prohibited in 1986. Volcano's residential inventory, centered around a median build year of 1995, is weighted toward the post-prohibition era. That context is relevant because the primary plumbing risk in older homes comes not from the municipal water supply but from what happens as water moves through lead-jointed pipes inside the structure - an exposure pathway that newer homes mostly avoid.

Most homes in Volcano were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

mg/L Avg Lead (Limit: 0.015)

Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

If aggregate samples sit below the EPA action level and just 25% of Volcano's inventory comes from the pre-rule era, systemic lead is not a dominant local concern. The aggregate still cannot tell a homeowner what is actually flowing from a specific faucet on a specific morning, which is why an in-home draw exists as a separate measurement at the household tier.
