Likely Pipe Material

With 71% 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.

Source: U.S. Census Bureau American Community Survey (ACS).

Housing Age Profile

Because the majority of Three Rivers's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1978 reflects a city where lead-era plumbing materials are common rather than exceptional.

Lead Exposure Risk for Children in Three Rivers

71%
Homes Built Before 1986

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.

Even where utility-side monitoring meets Lead and Copper Rule requirements, the 71% pre-rule share in Three Rivers keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.

Flood damage can add significantly to the estimated <strong>$2,900</strong> remediation cost per household.

Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
