Top Contaminants in Port Gibson Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Port Gibson
With 60% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Housing age is one of the most reliable proxies for plumbing-era lead risk, because two federal milestones - the widespread use of lead pipes before 1970 and the continued use of lead solder until 1986 - define the highest-risk tiers of the residential housing stock. With a median build year of 1970, Port Gibson falls squarely within the older range - meaning a large fraction of the housing was built under the plumbing standards of those earlier eras. The distribution above captures where that risk concentrates, and why older neighborhoods warrant particular attention from residents concerned about tap water quality.
Over half of homes in Port Gibson were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Port Gibson Homeowners
The cost-to-value ratio in Port Gibson is in the moderate range - neither dismissible nor alarming, but above the threshold where remediation can be treated as incidental. Most homeowners here are weighing a real equity commitment, and the moderate classification reflects that accurately.
Remediation costs are moderate relative to home values in Port Gibson. The estimated $950–$2,400 range is manageable for most homeowners but still worth budgeting for. Home values are 33% below the Mississippi average.
Lead Exposure Risk for Children in Port Gibson
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.
Older interior plumbing shapes the local picture: 60% of Port Gibson homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Historical NFIP Claim Context in Port Gibson
Historical NFIP data for Port Gibson contains 182 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $15,613. 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>$1,500</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.
