Likely Pipe Material

With 69% 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.

Housing Age Profile

Federal plumbing rules changed in two stages - lead pipes were phased out before 1970, and lead solder was banned in 1986 - but in Berthold, where the median build year is 1973, most of the housing was already in place before those rules took effect. The materials installed under older standards remain embedded in a substantial portion of the residential inventory today.

Over half of homes in Berthold 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 Berthold Homeowners

The Berthold equity share sits above the low tier but short of the range where remediation becomes a heavy financial burden - the cost-to-value ratio is moderate, and deliberate planning is the key practical lever for most homeowners.

$217,200
Est. Remediation
$2,900
Remediation as % of home value 1.3%

Remediation costs are moderate relative to home values in Berthold. The estimated $1,900–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 24% above the North Dakota average.

Lead Exposure Risk for Children in Berthold

69%
Homes Built Before 1986
0.0017
mg/L Avg Lead (Limit: 0.015)

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.

Reading the local data together points toward a structural gap that matters more here than in low-exposure communities. 69% of Berthold stock comes from the pre-rule era, and citywide monitoring either approaches or sits beyond the federal benchmark under Lead and Copper Rule sampling. A baseline kit fits the routine-diligence category, with certified filtration available via retailer networks where confirmed faucet results warrant additional measures.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Berthold contains 4 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $17,454. 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>$2,900</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.
