Key Contaminants Detected in Little Rock
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Protecting Children from Lead in Little Rock
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Available area-level lead records for Little Rock do not determine the lead level at an individual tap. Testing is the only way to confirm your water's lead content.

Historical Flood-Claim Evidence for Little Rock
Historical NFIP data for Little Rock contains 997 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $22,526.

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.
