Water Resources

HSW Engineering, Inc. has extensive experience in the planning, management and development of water supply needs/sources; water treatment and water conservation programs such as safe aquifer yield determination, establishment of minimum flows and levels, water distribution system design and optimization, groundwater modeling, saltwater intrusion modeling, watershed modeling and flood area delineation, stormwater conveyance, environmental remediation evaluation, design and optimization, environmental forensics, nutrient and sediment transport and estuarine systems.

Our staff has prepared and reviewed applications for water use, aquifer recharge, environmental resource, stormwater NPDES, dredge and fill, and domestic and industrial wastewater disposal permits at the state and federal level. Numerical ground- and surface-water models, statistical methods, and Geographic Information Systems (GIS) are used to characterize and evaluate water resource, ecological, and geophysical data.

HSW’s engineers and scientists are experienced in designing and implementing monitoring programs ranging from synoptic surveys such as wetland assessments and delineations and marina flushing studies to continuous recording rainfall, runoff, water level and water quality monitoring. Several senior scientists and engineers have provided expert and factual testimony, and environmental rule-making support related to geology, hydrogeology, water resources, groundwater modeling, and permitting.
