Water is key to life on our planet. Our engineers understand the complexities involved in managing groundwater and surface water as resources, and the trade-offs needed to balance supply and demand, economic and social factors, and the integrity of the natural environment. We have the expertise in hydrology, hydraulics, and hydrogeology to model, predict, and design solutions. A leader in the assessment and rehabilitation of surface water bodies, Pioneer’s experience includes floodplain surveys, mapping and delineation, wetlands delineation and design, stream reconstruction and restoration, streambank stabilization, hydraulic structure designs, irrigation system designs, fish passage design, storm water system evaluation and design, surface water sampling and monitoring, and water treatment. Our hydrogeology group’s experience includes data collection, groundwater and geochemical modeling, contaminated aquifer remediation, water supply assessment, dewatering system designs, and operation of treatment system designs. Our experience includes leading the evaluation, design, and construction oversight for a myriad of groundwater and surface water projects throughout the northwest. Many of these projects include developing, enhancing, preserving, and managing water resources to benefit public health, safety, and welfare, but also provide economic growth and educational outreach opportunities.
