Every three years, the Alaska Department of Environmental Conservation (ADEC) conducts a comprehensive review of the Water Quality Standards (WQS) in 18 AAC 70. This review helps to keep the pollution limits for Alaska's waters up to date by integrating the latest science, technology, policy, and federal requirements into how the State regulates water quality.
