Response to an oilspill on the Kalamazoo River

Enbridge Energy Partners LLP (Enbridge) reported a 30-inch pipeline ruptured on Monday, July 26, 2010, near Marshall, Michigan. The release, estimated at 819,000 gallons, entered Talmadge Creek and flowed into the Kalamazoo River, a Lake Michigan tributary. Heavy rains caused the river to overtop existing dams and carried oil 30 miles downstream on the Kalamazoo River. As the federal agency in...

NAWQA Groundwater

The National Water-Quality Assessment Program (NAWQA) provides an understanding of water-quality conditions; whether conditions are getting better or worse over time; and how natural features and human activities affect those conditions. Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis. Monitoring data are...

Antibiotic Resistance

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts research on antibiotic-resistant bacteria and their genes. We have concentrated our studies on antibiotic-resistant bacteria of human-health concern, including vancomycin-resistant enterococci, methicillin-resistant Staphylococcus aureus (...

Microbiological Water Quality

Recreational water and industrial discharges are regulated by other federal and state agencies across the country. The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts studies to understand the fate and transport of fecal indicator bacteria in surface and groundwater to aid state and federal partners. A variety of standardized protocols are used to...

Microbial Ecology

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts ecological studies on the structure and function of eubacterial and archeal communities in the environment. Studies of this type give us basic information about the composition and functionality of different microbial communities and allow us to investigate the effects that natural and...

Microbial Source Tracking

It is often important to understand the source of fecal indicator bacteria, pathogens, or chemicals that impair the normal use of water. Antibiotic-resistant bacteria and their genes, specific bacterial pathogens (such as E. coli O157:H7 which is primarily associated with cattle), and host-associated bacterial genes (such as human or animal specific Bacteroides genes), can be used to evaluate...

Silver Lake Nutrient Study

Recently, elevated chlorophyll-a concentrations were found related to persistent algal blooms on Silver Lake in Oceana County, MI.  Elevated chlorophyll-a concentrations, high phosphorus concentrations during summer months, as well as a decrease in water clarity indicated potential accelerated eutrophication processes during the last two years, and underscore a need to characterize water and...

Evaluation of Phosphorus Reduction in Targeted Watersheds

The Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious threats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Three Priority Watersheds have been targeted by the Regional Working Group's Phosphorus Reduction Work Group (Fox/Green Bay, Saginaw, and Maumee) and...

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...

Water Use

The USGS compiles water use information by State including estimated amounts, sources, and categories of use every five years since 1950. Sources include surface water and groundwater, both fresh and saline. Categories include public supply, domestic, livestock, industrial, irrigation, and thermoelectric power. These data provide a source of information about regional and national trends in...

Lansing Area Emerging Contaminants

The USGS, in cooperation with the Tri-County Regional Planning Commission, will analyze water sample results from 20 Lansing area wells. The objective of this study is to investigate well characteristics and other factors that may influence the susceptibility of drinking water-supply wells to contamination by contaminants of emerging concern. This information can be used by Lansing and other...

Mobile River Basin Study

The Mobile River Basin in Alabama, Georgia, Mississippi, and Tennessee is one of the 59 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound,...
