Because the majority of Erhard's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1972 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Erhard were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Remediation costs are moderate relative to home values in Erhard. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 8% below the Minnesota average.
Lead Exposure Risk for Children in Erhard
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.
When older housing represents 62% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Erhard address.

Flood & Climate Risk in Erhard
Within the NFIP's national dataset, Erhard falls in moderate-exposure territory — 3 documented incidents spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Erhard has a moderate flood history with 3 FEMA claims averaging $12,862 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
