Hydropower Licensing and Compliance
To help clients achieve stringent water quality goals, Geosyntec provides rigorous assessment and modeling services to assess the sources and factors that affect the delivery of critical pollutants across watersheds. Through our comprehensive studies and analyses, we provide technically defensible tools and approaches that can be used in the development of Total Maximum Daily Load (TMDL) calculations and watershed protection plans. In addition, we frequently turn to Use Attainability Analyses to examine site-specific water quality criteria that affect attainability goals under natural, human-caused, and economic conditions. Our hydrodynamic and water-quality models integrate inputs from point and nonpoint sources to support our engineers and scientists as they study impacts on water quality in receiving water. These models allow us to understand the assimilative capacities of a given body of water, propose best management practices that can affect pollutant impacts, and predict the time required for a system to recover after being altered. Using watershed studies, water quality monitoring, and hydrological and hydrodynamic modeling, we also can assess compliance with local, state, and federal water quality standards. Using all this information, we are better able to evaluate the magnitude, frequency, and duration of impacts of a wide variety of pollutant sources. Our practitioners offer extensive experience with geographic information system applications for spatial analysis, planimetric and thematic mapping, and data representation. We employ watershed models including the Watershed Characterization System (WCS), Better Assessment Science Integrating Point and Nonpoint Sources (BASINS), and the Watershed Assessment Model (WAMView). We also employ the Water Quality Analysis Simulation Program (WASP), the Environmental Fluid Dynamics Code (EFDC), and the Stream Water Quality Model (QUAL2K) for hydrodynamic and water-quality models. Our practitioners are at the forefront of policy analyses, regulatory compliance, and technology applications that promote sustainable water resources management and ecosystem restoration. We have extensive experience helping local governments develop and negotiate long-term control plans for combined sewer overflows, National Pollutant Discharge Elimination System (NPDES) permits, and consent orders. We also comment on Clean Water Act issues at the state and national level, including the development of new recreational use criteria for water bodies across the county and for the U.S. Environmental Protection Agency's new framework for integrated planning for wastewater and stormwater.

Urban Stormwater Management, Planning, & Design
Geosyntec's engineers and scientists stand among the world's foremost experts in urban stormwater management. We are innovators who design best management practices to mitigate impacts to surface water quality, enhance water conservation strategies, and contribute to municipal water supplies. Our professionals develop and implement comprehensive water quality master plans and site-specific designs using green infrastructure concepts for long-term stormwater control. We also guide the development and design of construction, industrial, and municipal programs for National Pollutant Discharge Elimination System (NPDES) regulatory program compliance. We have evaluated the opportunities, constraints, effectiveness, and costs associated with a variety of low impact development and green-streets options and have provided conventional treatment control BMPs for maintaining water quality control. We provide end-to-end solutions for a wide variety of applications from proprietary cistern sizing and optimization modeling and water collection and pre-filtration strategies, to designs for filtration, treatment, and water distribution systems. Our water resources engineers specialize in surface-water and groundwater interactions, ecosystem restoration, multi-beneficial project development, hydromodification management, and erosion and sediment control. In addition, our practitioners have been instrumental in developing, publishing, and supporting numerous stormwater guidance and design manuals. Geosyntec professionals established and continue to contribute to the International Database on Urban Stormwater BMP Design and Performance. We frequently present state-of-the-practice training sessions and workshops on stormwater management, NPDES regulatory program requirements, erosion and sediment control technologies, and BMP performance and design.
