Water quality is an important factor in managing wetlands. Water quality in wetlands is affected by the type of soil, vegetation, position on the landscape, topography, water quantity (amount of flow), climate, groundwater and surface water chemistry, and hydrology. States are increasingly interested in developing water quality standards for wetlands (which may differ in criteria from water quality standards for streams or lakes).
A water quality standard is a legally established state regulation consisting of three main parts: (1) designated uses, (2) criteria and (3) anti-degradation policy, and often a fourth part, general policies addressing implementation.To date, 15 states have adopted wetland-specific water quality standards. ASWM has provided resources for states and tribes that are developing criteria for adoption of water quality standards, as well as other information related to wetlands and water quality, on this page.
ASWM prepared four issue papers for the State of Maryland in 2010 with recommendations for the state to develop criteria for adoption of state wetland-specific water quality standards. They have been updated with funding support from the U.S. Environmental Protection Agency.

This paper addresses several key issues: What are Clean Water Act and U.S. Environmental Protection Agency requirements for state adoption of water quality standards for wetlands? What wetland water quality standards have other states adopted? What recommendations may be made to states based upon these requirements and state experiences? This paper was prepared to assist the Maryland Department of the Environment (MDE) in preparing draft water quality criteria for wetlands. It has been updated with funding support from the U.S. Environmental Protection Agency.

This paper has been prepared to stimulate discussion. Recommendations are based, primarily, upon lessons learned from the fourteen states which have adopted explicit water quality standards for wetlands. More detailed recommendations concerning content of wetlands and water quality standards based upon the experience of other states are contained in a companion paper: Jon Kusler, Water Quality Standards for Wetlands. This is one of several papers on the subject of wetlands and water quality standards prepared by the author for the Maryland Department of the Environment. It has been updated with funding support from the U.S. Environmental Protection Agency.

This paper has been prepared to stimulate discussion. What are the implications and state management options for wetlands that are listed on a state Clean Water Act 303(d) list because they fail to meet “designated use” criteria under the Clean Water Act? What suggestions may be made to a state for addressing such wetlands? What are the unanswered policy and legal questions? This paper was prepared for the Maryland Department of the Environment. It has been updated with funding support from the U.S. Environmental Protection Agency.

This paper has been prepared to stimulate discussion. It addresses several key issues: What are the U.S. Environmental Protection Agency (EPA) requirements for applying Total Maximum Daily Loads (TMDLs) to wetlands? To what extent have other states adopted TMDLs for wetlands? What recommendations may be made to concerning wetlands and TMDLs based upon experiences to date? This paper was prepared for the Maryland Department of the Environment. It has been updated with funding support from the U.S. Environmental Protection Agency.
