Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Indianola Infrastructure Age
With 71% 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
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Indianola's median build year of 1974 reflects a housing stock where these older materials are a pervasive feature — not a rare legacy — of the residential plumbing landscape.
Over half of homes in Indianola were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Older stock in Indianola represents 71% of the inventory, and citywide monitoring runs at or above the federal action level — making an in-home read a standard household-level step.
