Why should Anne Arundel County be Concerned About TMDLs?
Based on the federal government’s Clean Water Act, all states are required to consider the development of TMDLs for waterbodies that do not meet water quality standards for various pollutants. All of the twelve major waterbodies in Anne Arundel County are impaired by two or more substances (e.g., nutrients, sediments, fecal coliform bacteria, toxics, biological, or metals). The Watershed Assessment and Planning program is continuously monitoring the state of TMDL development and water quality analyses to justify the delisting of waterbodies from the MDE 303(d) impairment list.

Progress Reports
Below are Programmatic and Implementation progress reports as required by the Maryland Department of the Environment. Programmatic Milestones are commitments to non-project improvements such as organizational, process, and capacity building changes that position Anne Arundel County to implement it's WIP. Implementation Milestones are commitments to on-the-ground activities that result in nutrient and sediment load reductions.
