Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile

Over the decades, Round Lake accumulated housing from multiple construction periods. The median build year of 1995 can be read against 1986, when lead solder in plumbing became federally prohibited - a regulatory line, not a safety line, and individual homes on either side of it can have different plumbing.

Median Year Built

Pre-1986 (lead solder era; lead paint banned 1978)
20%
Pre-1970 (Lead Pipes Risk)
Pre-1970 (20%) 1970–1986 (18%) Post-1986 (62%)

Most homes in Round Lake were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Round Lake

Homes Built Before 1986
0.012
mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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.

Even though compliance with the federal lead action level is judged on each system's own 90th percentile, the average of those results across Round Lake ZIP codes, 0.010 mg/L or more, is a reason to check at home, particularly in the 38% of housing built before 1986.

Historical Flood-Claim Evidence for Round Lake

200
Total FEMA Flood Claims
$9,663
Avg Reported Sum With Payment Data
100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Round Lake contains 200 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,663. 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 $300 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 Round Lake

  1. 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.
  2. Install a certified water filter. For Consumer Confidence Rule, listed in the water-quality records for Round Lake: 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.
  3. Check your home's plumbing. With 38% of homes built before 1986, lead solder is a real possibility.
