What Minneapolis Residents Can Do

Test Your Water

• Order a certified lab test - home test kits cost $20–50 and cover lead, bacteria, and common contaminants
• Request your utility's CCR (Consumer Confidence Report) - your water provider must publish this annually
• Check your ZIP code - each area in Minneapolis has different water systems and risk levels

Filter Your Water

• NSF 53-certified filter for lead - recommended for homes built before 1986
• Reverse osmosis system removes 95%+ of contaminants including lead, PFAS, and nitrates ($150–400)

Test for Radon

• Minneapolis is in a high-risk radon area
• Short-term radon test kits cost $10–25
• If levels exceed 4 pCi/L, EPA recommends professional mitigation

Housing Age Profile

Banned from residential plumbing in 1986, lead solder was a near-universal feature of copper plumbing before that cutoff. In Minneapolis, where the median build year is 1964, the majority of housing falls into the post-ban category - though the older fraction of the stock still carries the residual risk that comes with pre-1986 pipe and solder materials.

Pre-1986 (Lead Paint Risk)

Pre-1970 (Lead Pipes Risk)

Most homes in Minneapolis were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Minneapolis: Lead Risk & Vulnerable Populations

0.002

mg/L Avg Lead (Limit: 0.015)

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.

Lead risk in Minneapolis appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Minneapolis: Flood History & Water Damage Risk

A moderate NFIP record for Minneapolis - 558 insurance claims paired with 0% of ZIP codes in FEMA flood zones - points to a flood history where water-quality pathways have likely been periodically relevant.

Total FEMA Flood Claims

~28

Est. Claims/Year

Minneapolis has a moderate flood history with 558 FEMA claims. 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.

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.
