Copper
Likely Pipe Material

With 66% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

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 Twin Lakes, where the median build year is 1974, 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 Twin Lakes were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How much of a Twin Lakes home's value does documented remediation represent?

Lead Exposure Risk for Children in Twin Lakes

0.0009
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.

Locally, 66% of Twin Lakes homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.
