Top Contaminants in Pewaukee Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Pewaukee
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing materials follow installation dates, not medians. Pewaukee records a median build year of 1997, and a meaningful share of its homes date from before the 1986 federal lead restrictions.
Most homes in Pewaukee were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Pewaukee Homeowners
Of the three cost-context tiers - low, moderate and elevated - Pewaukee is in the low one.
Estimated remediation costs in Pewaukee can be compared with local home values. The $700–$2,300 estimated range can be set against the median property value; actual costs vary by home. Home values are 84% above the Wisconsin average.
Lead Exposure Risk for Children in Pewaukee
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Several steps can clarify lead exposure for a Pewaukee household. The area figure, an average of ZIP-level 90th-percentile results, is 0.010 mg/L or higher, and the pre-1986 share of local homes is about 37%. The water utility's lead service line inventory shows how a home's service line is classified, a certified laboratory test measures lead at the tap, and a filter certified to NSF/ANSI 53 for lead reduction is an option where results show lead.

Historical NFIP Claim Context in Pewaukee
Historical NFIP data for Pewaukee contains 32 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $21,697. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
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. The $1,200 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in Pewaukee
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. For Gross Alpha (excl. radon and uranium), listed in the water-quality records for Pewaukee: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 37% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
