Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Erath Infrastructure Age
With 46% 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
With a median build year of 1982, Erath's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 — the year lead solder in plumbing was federally banned — meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in Erath were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Erath
Middle of the range — Erath homeowners face a remediation share that calls for real financial attention without reaching crisis territory.

Erath: Lead Risk & Vulnerable Populations
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.
Routinely in Erath, where 46% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Erath: Flood History & Water Damage Risk
Flood exposure in Erath is substantial — 1752 NFIP claims on record and 100% of ZIP codes within FEMA-designated zones. That volume of documented flood activity places water-quality implications of flooding firmly in the active-risk category rather than the hypothetical.
Erath has a significant flood history with 1,752 FEMA flood insurance claims on record, averaging $33,534 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$1,800</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.
