How Old Is Esko's Housing Stock?
With 57% 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 1971, as in Esko, 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 Esko were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Esko: Remediation Cost in Perspective
Because property values in Esko comfortably exceed estimated remediation costs, the equity impact here is proportionally small.
Remediation costs in Esko are relatively low compared to home values. The $1,200–$3,300 estimated range is a small fraction of median property value. Home values are 25% above the Minnesota average.
Protecting Children from Lead in Esko
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.
Older stock in Esko represents 57% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.

Climate-Related Water Risk for Esko
Over the multi-decade window covered by the National Flood Insurance Program, Esko has accumulated 7 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
Esko has a moderate flood history with 7 FEMA claims averaging $28,763 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>$2,200</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.

What You Can Do in Esko
- 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 57% of homes built before 1986, lead solder is a real possibility.
