Barbara Galloway is the senior hydrologist at ERO Resources, where she has been completing surface and ground water investigations for 15 years. She has served as a project manager on a variety of water-related projects. Barbara has 23 years of experience in surface and ground water quantity and quality data collection, analysis and modeling, water rights and administration, water supply studies, environmental impact analysis and hazardous and non-hazardous site investigations and remediation. Prior to becoming a consultant, she was a state water resources regulator. Her clients have included the federal government, state government, municipalities, water supply companies, irrigation districts, developers, industrial and commercial businesses, individuals, attorneys and golf course operators. Barbara has also provided expert witness testimony.

Summary of Experience

Surface and Ground Water Quantity/Supply. Barbara has completed hydrologic studies to determine source of water supply, evaluated water supply systems, developed water budgets, calculated optimal reservoir size, estimated consumptive use and return flows and measured seepage and evapotranspirative losses. She has evaluated baseline watershed conditions prior to site development. Barbara has calculated storm runoff and peak discharges for ungaged watersheds, evaluated climatological records and stream gage data, reservoir storage and climatological data and completed channel stabilization evaluations. She has conducted aquifer tests, modeled impacts to surface flows due to ground water pumping and completed ground water flow and capture zone modeling. Barbara has also evaluated site hydrogeology, location and well design.

Water Rights and Administration. Barbara has prepared augmentation plans, substitute water supply plans and changes of water rights for municipalities, industry and private water users. She has compiled historical surface and ground water use data and completed water rights evaluations and appraisals, including yield calculations and consumptive use analyses. Barbara has determined impacts due to federal instream flow claims in downstream river reaches and evaluated river management models.

Water Quality Evaluation, Monitoring and Management. Barbara’s experience includes surface and ground water monitoring and analysis, evaluation of water quality monitoring programs and mitigation plans, preparation of water quality management plans and completion of applications for Section 401 water quality certification. She has evaluated the impacts to streams from erosion, sedimentation and runoff from roadways and other developed areas. She has also evaluated impacts to ground water from leaking underground storage tanks, spills and improper waste disposal practices. Barbara has assisted clients with NPDES/CDPS permitting for construction dewatering and stormwater discharges. She has completed CDOT’s Stormwater Management and Erosion Control course and has prepared and/or reviewed stormwater management plans, erosion control plans, water quality monitoring plans and drainage plans. In addition, Barbara has provided Best Management Practices recommendations to numerous clients.

Environmental Impact Assessments. Barbara has served as project hydrologist during the preparation of environmental impact statements and environmental assessments. She has assisted federal, state and municipal governments, as well as water districts, with technical analyses of surface and ground water quality and quantity impacts for proposed mines, water supply alternatives (such as reservoirs, pipelines, changes in use and points of diversion, etc.), roads, utility corridors and recreational sites. She has evaluated changes to surface flows, ground water levels, water quality, stream morphology and downstream water rights. She has developed and used water quality models as part of her analyses for evaluating stream impacts.

Hazardous and Non-Hazardous Site Investigations and Remediation. Barbara has experience installing monitoring wells, using numerous methods to collect vapor, soil, sediment, seep, sludge, ground and surface water quality samples at underground storage tank, spill and waste disposal sites. She has been involved with numerous site characterizations and the design and installation of remediation systems at commercial and industrial sites. She has researched and is familiar with local, state and federal environmental regulations concerning hazardous and non-hazardous waste sites. Barbara has also performed analytical and digital surface and ground water modeling, capture zone modeling and contaminant transport modeling.
