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.

In recent monitoring under the Lead and Copper Rule, citywide samples for Oswego have approached or crossed the regulatory action level on multiple occasions. Combined with 78% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
