Water Chemistry Monitoring Project - Rivers and Streams
In support of the Michigan Department of Environmental Quality (MDEQ) Water Chemistry Monitoring Project, the USGS Michigan Water Science Center has been collecting long-term water quality data for Michigan's rivers and streams.
Water samples are collected 4 to 12 times a year for selected nutrients, trace metals, sediment, and other water-quality constituents. Intensive sampling (12 samples per year) is being conducted on major Great Lakes Tributaries including the Au Sable River, Saginaw River, Clinton River, Kalamazoo River, Muskegon River, and Grand River. Following a rotational schedule, other streams are sampled intensively every 5 years in addition to being sampled quarterly during their off years. Results of this program are being used by MDEQ to help determine the water-quality status of Michigan's rivers and streams, and to estimate chemical loads to the Great Lakes. This project has been collecting data since 1998, and Statewide trends in water-quality for the major rivers and streams have been evaluated using this data. Information on the MDEQ Water Chemistry Monitoring Project is available here.
Reports are available for the following studies:
Antibiotic, pharmaceutical, and wastewater-compound data for Michigan, 1998-2005
Trends in Surface-Water Quality at Selected Ambient-Monitoring Network Stations in Kentucky, 1979-2004
Analysis of Water-Quality Trends for Selected Streams in the Water Chemistry Monitoring Program, Michigan, 1998-2005
Screening for the Pesticides Atrazine, Chlorpyrifos, Diazinon, Metolachlor, and Simazine in Selected Michigan Streams, March-November 2005
Atrazine concentrations in stream water and streambed sediment pore water in the St. Joseph and Galien River basins, Michigan and Indiana, May 2001-September 2003
