Lankin Infrastructure Age
With 83% 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
Plumbing risk in older housing is defined by two eras: the pre-1970 period when lead pipes were commonly used for service lines, and the 1970-to-1986 period when lead solder remained standard in copper plumbing until the federal ban. Lankin's median build year of 1949 lands in a range where both eras are heavily represented in the housing stock. That creates an elevated aggregate environment for plumbing-related lead exposure — one that city-level water quality averages don't capture, because the risk sits inside individual properties rather than in the distribution system.
Over half of homes in Lankin were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Lankin
Because estimated remediation claims a substantial fraction of typical Lankin property equity, the household financial perspective here requires serious advance planning — the cost-to-value ratio is in the elevated tier and warrants structured preparation.
At 2.9% of home value, remediation costs in Lankin represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$3,300. Home values here are 53% below the North Dakota average.
Lankin: 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.
83% — that captures the slice of Lankin housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.

Lankin: Flood History & Water Damage Risk
The NFIP has been tracking flood insurance claims across the United States for decades, building a data record that reflects cumulative flood history at the local level. For Lankin, that record shows a modest total that places the community on the lower end of flood exposure. That context matters for water quality: flooding can compromise both public treatment infrastructure and private wells, but the severity of those effects depends heavily on event magnitude and frequency. At low claim volumes, those pathways to water quality disruption remain largely theoretical rather than documented local risks.
Lankin has a relatively low flood history with 4 FEMA claims on record. While risk is limited, severe weather events can still impact water infrastructure.
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. Flood damage can add significantly to the estimated <strong>$2,400</strong> remediation cost per household.

What You Can Do in Lankin
- Test your water at home. City-level data shows averages — your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
- Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
- Check your home's plumbing. With 83% of homes built before 1986, lead solder is a real possibility.
