Lead Exposure Risk for Children in Danielson

79%
Homes Built Before 1986
0.0023
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.

If 79% of the Danielson inventory comes from before the federal ban on lead-bearing solder - and if utility samples sit at or near 0.015 mg/L - the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

What You Can Do in Danielson

  1. Test your water at home. City-level data shows averages - your tap may differ. NSF-certified test kits cost $20-40 and give results in days.
  2. Install a certified water filter. An NSF-certified pitcher or under-sink filter removes most common contaminants.
  3. Check your home's plumbing. With 79% of homes built before 1986, lead solder is a real possibility.
