Water Quality and Contaminants
 Scientists from LGL have expertise related to:
- Eutrophication and nutrient issues
- Mercury and other metal contaminants
- Acid rock drainage and metal leaching
- Hydrocarbon and other organic contaminants
- Sediment loading from erosion
- Water balance modeling and contaminant mass balance modeling
- Characterization of physical characteristics such as temperature, salinity, conductivity, and dissolved oxygen
- Effects of contaminants on human and environmental health
 The objectives of our investigations commonly include:
- Environmental impact evaluation
- Mine planning and remediation
- Lakeshore development planning
- Sediment control mitigation
- Restoration of aquatic habitats
- Aquaculture impact evaluation and planning
- Evaluation of human health concerns
- Inventory and basic characterization of lakes and streams
 Specialized methodologies:
- Acute and chronic toxicity testing
- “Clean” sampling of water, biota, and sediments for contaminant measurement
- In situ measurement of aquatic physical and chemical parameters
- Statistical analysis and interpretation of contaminant concentration information
- Measurement of chlorophyll and other indicators of primary productivity
- Identification of phytoplankton and zooplankton as indicators of water quality
- Sediment control strategies as part of aquatic habitat restoration
