Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Manson Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Prohibited from residential plumbing since 1986, lead solder divides Manson's housing stock along a timeline that the median build year of 1997 straddles. A meaningful share of homes predates the ban — a configuration that places moderate aggregate pressure on plumbing-related lead risk, distributed unevenly across neighborhoods.
Most homes in Manson were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Manson
In Manson, property values comfortably outpace what documented remediation typically costs — the equity share is proportionally low.
Remediation costs in Manson are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 40% above the Washington average.
Manson: 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.
Before the federal solder ban, lead solder was a routine plumbing material, and 39% of the Manson inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Manson: Flood History & Water Damage Risk
Flood exposure in Manson is meaningful by NFIP measures — 3 claims on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Manson has a moderate flood history with 3 FEMA claims averaging $3,536 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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>$1,200</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.
