Top Contaminants in Smithfield Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Smithfield
With 53% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Viewed through the lens of construction era, Smithfield has a median build year of 1986; houses completed ahead of 1986 can hold lead-bearing solder or fittings.
Over half of homes in Smithfield were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Smithfield Homeowners
This section sets two area figures side by side for Smithfield: the median home value and an estimated remediation cost. Here the estimate equals no more than 1% of that value, which places the city in the low tier; it is an area estimate, and the cost for any one property can be higher or lower.
Estimated remediation costs in Smithfield can be compared with local home values. The $700–$2,300 estimated range can be set against the median property value; actual costs vary by home. Home values are 2% below the North Carolina average.
Lead Exposure Risk for Children in Smithfield
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.

Historical NFIP Claim Context in Smithfield
Historical NFIP data for Smithfield contains 170 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $51,672. 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 $1,200 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.
Source: historical FEMA National Flood Insurance Program (NFIP) claim records. No current FEMA property-map designation is asserted.
What You Can Do in Smithfield
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Lead and Copper Rule, listed in the water-quality records for Smithfield: 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 53% of homes built before 1986, lead solder is a real possibility.
