The South Dakota Department of Environment and Natural Resources requests water quality data as part of its process to complete a biennial assessment of South Dakota’s lakes and streams.
The 2014 Integrated Report must be completed and submitted to the U.S. Environmental Protection Agency by April 1, 2014. The report provides an assessment of the quality of South Dakota’s surface water resources and identifies the impaired waters that require a total maximum daily loads (TMDL).
A total maximum daily load calculates the amount of pollution a waterbody can receive and still meet water quality standards along with supporting assigned beneficial uses. Once TMDLs are determined, local, state and federal activities can be directed toward improving the quality of the waterbody.
The department’s 230-page 2012 Integrated Report can be viewed online at http://denr.sd.gov/documents/12irfinal.pdf.
To develop a comprehensive list, the department is soliciting water quality data to help determine the quality of South Dakota’s waters. Chemical, physical and biological data will be considered. Beach closure information, including date, duration and water quality results is also requested.
Persons or organizations having water quality data should contact Shannon Minerich at (800) 438-3367 or by e-mail Shannon.Minerich@state.sd.us by Aug. 23, 2013.
Water quality data can also be sent to Shannon Minerich at: South Dakota Department of Environment and Natural Resources; 523 East Capitol Avenue; Pierre, South Dakota 57501-3182.
