Key Contaminants Detected in Roswell
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Roswell's Housing Stock?
With 43% 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
Some cities skew heavily toward one construction era; Roswell does not. The median build year of 1981 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk — with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.
Most homes in Roswell were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Roswell: Remediation Cost in Perspective
Low proportionality — that's the Roswell picture when remediation costs are placed against typical home equity.
Remediation costs in Roswell are relatively low compared to home values. The $633–$2,267 estimated range is a small fraction of median property value. Home values are 161% above the Georgia average.
Protecting Children from Lead in Roswell
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.
If 43% of the Roswell inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Climate-Related Water Risk for Roswell
NFIP records stretching across multiple decades show Roswell accumulating 161 claims and carrying 67% of its ZIP codes inside FEMA flood zones — evidence of meaningful exposure that extends beyond isolated incidents. The mechanisms linking flooding to water quality haven't changed: treatment facilities can be overwhelmed, wells can be infiltrated, and distribution systems can experience backflow. For a community at this exposure level, those mechanisms shift from hypothetical to periodically relevant.
Roswell has a moderate flood history with 161 FEMA claims averaging $15,147 per payout. 67% 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>$1,367</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.
