Escondido: Lead Risk & Vulnerable Populations

ZIPs Mapped to a System Above the Lead Action Level
0.0138
mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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.

If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

1 ZIP code (14% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.

Escondido: NFIP Claim Records and Water-Quality Context

85
Total FEMA Flood Claims

Avg Reported Sum With Payment Data
25%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Escondido contains 85 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $8,777. Among ZIP codes with claim records, 25% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.

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. The $1,580 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
