Michigan Bacteriological Research Laboratory (MI-BaRL)
The USGS Michigan Water Science Center Bacteriological Research Laboratory (MI-BaRL) in Lansing, MI provides a variety of modern analytical approaches to understand bacteriological contamination and microbial ecology in diverse aquatic environments. The MI-BaRL laboratory has examined beach microbiology, the occurrence of antibiotic-resistant bacteria in surface water, and the occurrence of microbial pathogens in surface water, ground water, and in drinking water supplies. In addition, several studies conducted in the MI-BaRL have examined the ecology of microbial communities in different settings, including sulfur rich springs, arsenic and hydrocarbon contaminated groundwater, and wastewater-contaminated surface and groundwater.
New Journal Article "Geographic Setting Influences Great Lakes Beach Microbiological Water Quality"
Understanding of factors that influence Escherichia coli (EC) and enterococci (ENT) concentrations, pathogen occurrence, and microbial sources at Great Lakes beaches comes largely from individual beach studies. Using 12 representative beaches, we tested enrichment cultures from 273 beach water and 22 tributary samples for EC, ENT, and genes indicating the bacterial pathogens Shiga-toxin producing E. coli (STEC), Shigella spp., Salmonella spp, Campylobacter jejuni/coli, and methicillin-resistant Staphylococcus aureus, and 108–145 samples for Bacteroides human, ruminant, and gull source-marker genes.

Relation Between Organic-Wastewater Compounds, Groundwater Geochemistry, and Well Characteristics for Selected Wells in Lansing, Michigan
In 2010, groundwater from 20 Lansing Board of Water and Light (BWL) production wells was tested for 69 organic-wastewater compounds (OWCs). The OWCs detected in one-half of the sampled wells are widely used in industrial and environmental applications and commonly occur in many wastes and stormwater. To identify factors that contribute to the occurrence of these constituents in BWL wells, the U.S. Geological Survey (USGS) interpreted the results of these analyses and related detections of OWCs to local characteristics and groundwater geochemistry.
Silver Lake Nutrient Loading Study (Oceana County, MI)
The Silver Lake Nutrient Loading Study began in August 2012 between the Silver Lake Improvement Board and project partners, which include the U.S. Geological Survey (USGS), the Annis Water Resources Institute (AWRI) , and Progressive AE. Recent persistent algal blooms, high phosphorus concentrations during summer months, as well as a decrease in water clarity underscore a need to characterize water and nutrient sources to Silver Lake (located in Oceana County, MI). The objective of the Silver Lake Nutrient study is to characterize the nutrient conditions and hydrologic inputs and outputs to Silver Lake in order to develop a water budget and nutrient budget for the lake. Once identified, information on nutrient sources can be used by the Silver Lake Improvement Board to implement management practices that best protect Silver Lake from potential negative effects associated with elevated nutrient concentrations.

Predicting Water Clarity Overview
The U.S. Geological Survey (USGS), in cooperation with the Michigan Department of Environmental Quality (MDEQ), has been monitoring the quality of inland lakes in Michigan through the Lake Water Quality Assessment monitoring program. This program is funded through the Michigan Clean Michigan Initiative, and the USGS Cooperative Program. However, only a portion of Michigan's inland lakes can be conventionally sampled each year. A technique was developed by USGS, modeled after Olmanson and others (2001), to predict water clarity and corresponding trophic state index (TSI) values based on the Carlson's Trophic State Index (TSI) in inland lakes greater than 20 acres using satellite remote sensing data.
