Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Herculaneum Infrastructure Age
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
The story of Herculaneum's housing stock is one of layered development - neighborhoods built in different decades, each carrying the plumbing standards of their era. The median build year of 1993 reflects that layered character. Before 1986, lead solder was standard in copper plumbing; before 1970, lead pipes were commonly used for service lines. A substantial portion of the pre-1986 homes visible in the distribution above still carry the plumbing materials of those earlier standards - creating a risk environment that the city-wide aggregate water data doesn't fully capture.
Most homes in Herculaneum were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Herculaneum
Looking at how documented remediation costs fit within Herculaneum property values, the equity share lands in the moderate tier - a finding that positions the household financial perspective between routine maintenance and a significant budget commitment, where most homeowners can successfully address documented issues by treating the expense as a planned financial priority rather than an unexpected one.
Remediation costs are moderate relative to home values in Herculaneum. The estimated $1,500–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 23% above the Missouri average.
Herculaneum: Lead Risk & Vulnerable Populations
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.
Routinely in Herculaneum, where 37% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Herculaneum: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Herculaneum contains 57 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $27,503. 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>$2,700</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.
