Top Contaminants in North Dartmouth Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in North Dartmouth
With 63% 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
Renovation history matters as much as age: in North Dartmouth, with a median build year of 1974, some older homes have been replumbed and some have not.
Over half of homes in North Dartmouth 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 North Dartmouth Homeowners
Because the median home value in North Dartmouth is large relative to the estimated cost of remediation, the ratio between them stays at or below 1%; that is a statement about two area-level numbers, not a quote for a particular house or a judgment about what an owner can pay.
Estimated remediation costs in North Dartmouth 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 18% below the Massachusetts average.
Lead Exposure Risk for Children in North Dartmouth
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.
Households with young children in North Dartmouth have two area numbers to weigh. One is the mean of 90th-percentile lead values reported for local ZIP codes, which is at or above 0.010 mg/L; the other is the 63% share of housing that dates from before 1986. Neither describes one home, and sending a tap sample to an accredited laboratory is how a family measures its own lead level.

Historical NFIP Claim Context in North Dartmouth
Historical NFIP data for North Dartmouth contains 15 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $8,039. 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 North Dartmouth
- 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 Haloacetic Acids (HAA5), listed in the water-quality records for North Dartmouth: 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 63% of homes built before 1986, lead solder is a real possibility.
