Key Contaminants Detected in Carrollton
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Carrollton'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
Some cities skew heavily toward one construction era; Carrollton does not. The median build year of 1994 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 Carrollton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Carrollton: Remediation Cost in Perspective
In Carrollton, documented water and safety issues can be addressed without making a meaningful dent in home equity — the financial proportionality here is favorable, and the commitment fits within standard property planning frameworks.
Remediation costs in Carrollton are relatively low compared to home values. The $760–$2,460 estimated range is a small fraction of median property value. Home values are 9% above the Georgia average.
Protecting Children from Lead in Carrollton
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.
Pulling a tap sample fills the gap that utility data cannot close, particularly here where 32% of housing dates from the pre-rule era and citywide monitoring sits at or above the regulatory mark in Carrollton.

Climate-Related Water Risk for Carrollton
Multiple flood events have been recorded for Carrollton through the NFIP — 39 claims in total, with 60% of ZIP codes in FEMA-designated zones — pointing to a flood exposure profile that merits inclusion in a water quality assessment without reaching high-severity planning territory.
Carrollton has a moderate flood history with 39 FEMA claims averaging $191,815 per payout. 60% 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.
