Surface Water Standards Table - Alaska

Surface Water Standards Table

Technical Memorandum

February 2022

Alaska Department of Environmental Conservation

Division of Environmental Health

Solid Waste Program

Surface water monitoring results should be compared to the standards in the table below. The standards are

based on the following hierarchy:

EPA Primary Drinking Water MCLs (40 CFR 141) as reference in 18 AAC 70.

Alaska Pollutant Discharge Elimination System (APDES) Multisector General Permit for Storm Water Discharges

Associated with Industrial Activity (MSGP), Sector L ¨C Landfills, Land Application Site, and Open Dumps.

National Secondary Drinking Water Regulation standards under 40 CFR 143.

ADEC 18 AAC 75.345, Table C groundwater cleanup levels

EPA Lifetime Health Advisory Levels

ADEC 18 AAC 70, Water Quality Standards

Where no standard exists, a site-specific standard will be developed by the facility in consultation with ADEC if the

constituent is detected in surface water.

The standards contained in this table are effective July 9, 2018. The standards will be updated as needed.
