MCL Recommendation for 1,2,3-Trichloropropane Public comments on draft Subcommittee reports are identical to those submitted in response to the Request for Public Input in September 2015. No revisions to the draft Subcommittee reports were needed, since these comments were considered in development of the drafts. Subcommittee report recommendations are: Health Effects Subcommittee: Health-based MCL - 0.0005 µg/L (0.5 ng/L) Testing Subcommittee: Practical Quantitation Level - 0.03 µg/L (30 ng/L) Treatment Subcommittee: “…can be reliably and feasibly removed by carefully designed GAC treatment below the recommended PQL of 30 ng/L.” The DWQI will therefore vote on an MCL recommendation of 0.03 µg/L (30 ng/L) for 1,2,3-trichloropropane.
