Housing Age Profile

The lead that enters tap water in older homes often comes not from the municipal supply but from the home's own plumbing — from solder used in copper joints before the 1986 federal ban, or from lead pipes installed before 1970. In Guerra, where the median build year is 1945, these older materials are widespread. More than half the residential stock predates the 1986 solder ban, and a significant fraction predates 1970 as well. For residents in those homes, the city-wide water quality picture is a less relevant frame than the specific materials inside their own walls and under their own street.

Over half of homes in Guerra were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Guerra: Lead Risk & Vulnerable Populations

100%
Homes Built Before 1986

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.

Wherever 100% of local housing was built before solder rules changed — as is the case in Guerra — a faucet-level sample closes the gap that aggregate utility data cannot.

What You Can Do in Guerra

  1. Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
  2. Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
  3. Check your home's plumbing. With 100% of homes built before 1986, lead solder is a real possibility.
