How Old Is Amboy's Housing Stock?
With 42% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Over the decades, Amboy accumulated housing from multiple construction periods. The median build year of 1997 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.
Most homes in Amboy were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Amboy: Remediation Cost in Perspective
In Amboy, estimated remediation comes to 1% or less of the median home value.
Estimated remediation costs in Amboy can be compared with local home values. The $450–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 11% above the Washington average.
Protecting Children from Lead in Amboy
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.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

What You Can Do in Amboy
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Nitrate, listed in the water-quality records for Amboy: 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 42% 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.
