Malden: Lead Risk & Vulnerable Populations
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.
CDC has identified no safe blood lead level in children, and lead in water can differ from one home to the next; in Malden, testing the water a child drinks is how to learn the lead level in that water, and a blood test is how to learn the child's level. About 78% of the city's homes date from before 1986.

Malden: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Malden contains 87 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $5,257. Among ZIP codes with claim records, 100% 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 $600 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.

What You Can Do in Malden
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. For Lead and Copper Rule, listed in the water-quality records for Malden: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 78% of homes built before 1986, lead solder is a real possibility.
