Housing & Infrastructure in Spring Grove
With 81% 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
When a city's housing median build year is 1955, as in Spring Grove, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Spring Grove 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 Spring Grove Homeowners
Because property values in Spring Grove comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Spring Grove are relatively low compared to home values. The $800–$1,500 estimated range is a small fraction of median property value. Home values are 25% below the Minnesota average.
Lead Exposure Risk for Children in Spring Grove
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.
Routinely in Spring Grove, where 81% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

What You Can Do in Spring Grove
- 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 81% of homes built before 1986, lead solder is a real possibility.
