Key Contaminants Detected in San Juan
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is San Juan'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
San Juan's housing stock skews relatively recent, with a median build year of 1992. Homes constructed after 1986 avoid the lead-soldered copper joints that were standard before the federal ban - reducing aggregate risk from plumbing as a contamination pathway.
Most homes in San Juan were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Protecting Children from Lead in San Juan

Pre-rule stock in San Juan accounts for 27% of the inventory - a modest fraction - and citywide samples land safely beneath the federal action mark.

Historical Flood-Claim Evidence for San Juan
Historical NFIP data for San Juan contains 88 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $13,737. 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 <strong>$1,800</strong> 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.
