The results for Round 3 (concluded in 2010) of unregulated contaminates monitoring are provided below. Round 4 (concluded in 2019) is available online by clicking here. Round 5 for the unregulated contaminates monitoring is scheduled to commence in 2023.

Unregulated contaminants are those that don't yet have a drinking water standard yet set by USEPA. The purpose of monitoring for these contaminants is to help EPA decide whether the contaminants should have a standard. A PDF file of the below tables is available here via Dropbox.

Please note that "ND" is Non-Detectable which means the result is below the method detection limit.
