We have extensive experience addressing surface water quality issues in lakes, ponds, streams, recreational waters, and coastal areas throughout the Northeast, in both rural and urban settings. We develop and execute sampling programs and data analysis to both assess water quality conditions and identify sources of specific water quality impairments such as elevated bacteria concentrations, harmful algal blooms, and excess aquatic vegetation. Our staff includes scientists and engineers with expertise in limnology, water chemistry, bio-monitoring, habitat assessment and restoration, and hydrology.
