Key Contaminants Detected in Centreville
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Centreville'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
Development in Centreville unfolded across multiple decades, and the median build year of 1993 reflects a housing inventory where eras of construction are genuinely mixed — including portions that predate the federal prohibition on lead solder in plumbing.
Most homes in Centreville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Centreville: Remediation Cost in Perspective
When remediation costs are measured against Centreville home values, the resulting ratio is in the low tier — addressing documented water and safety issues here claims only a minor fraction of typical equity, and most homeowners are in a position where the financial commitment is straightforward rather than a material burden on their household budget.
Remediation costs in Centreville are relatively low compared to home values. The $950–$2,400 estimated range is a small fraction of median property value. Home values are 8% above the Maryland average.
Protecting Children from Lead in Centreville
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.
Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 39% of Centreville stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.

Climate-Related Water Risk for Centreville
Taken together, Centreville's 22 NFIP flood insurance claims and 100% FEMA flood zone coverage place it in the moderate range of exposure. That middle position has specific implications for water quality. The contamination pathways that flooding can open — surface water overwhelming treatment facility intake, floodwaters infiltrating private wells, distribution pressure changes creating backflow — are not constant risks in a moderate-exposure community. But they do become active during significant flood events, and the claim record here indicates enough of those events to make flood timing an occasional factor in local water quality conversations.
Centreville has a moderate flood history with 22 FEMA claims averaging $11,766 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>$1,500</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.
