Key Contaminants Detected in Lafayette
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Lafayette's Housing Stock?
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
Pre-1986 construction carries elevated plumbing-era lead risk because lead solder was widely used before that federal ban. In Lafayette, the median build year of 1998 indicates a housing stock where that older fraction represents a significant share of the residential inventory.
Most homes in Lafayette were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Lafayette: Remediation Cost in Perspective
Equity impact data for Lafayette lands in the favorable tier — remediation claims a small slice of what properties here are worth.
Remediation costs in Lafayette are relatively low compared to home values. The $1,750–$3,900 estimated range is a small fraction of median property value. Home values are 47% above the Colorado average.
Protecting Children from Lead in Lafayette
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.
When older housing represents 39% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Lafayette address.

Climate-Related Water Risk for Lafayette
Within the NFIP's national dataset, Lafayette falls in moderate-exposure territory — 12 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Lafayette has a moderate flood history with 12 FEMA claims averaging $1,151 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>$2,700</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.
