Understanding how water interacts with the surface and subsurface environment at any contaminated location is critical to designing innovative and cost-effective remediation systems and site-management strategies. By delineating and understanding the geology and hydrogeology affecting contaminated sites, our experts design strong conceptual site models and groundwater-remediation programs. Ultimately, hydrogeological characterization and modeling affects the performance of any remediation technologies deployed as a solution.

Water Supply Production Wells

The ability to develop and enhance sustainable water resources while balancing the benefits to human populations and water-dependent ecosystems represents one of the more critical issues facing communities across the globe. Designing effective and sustainable solutions that identify and address issues related to surface water and groundwater supplies can be complex, frequently requiring a multidisciplinary approach. The challenges associated with water supply development in California, for example, are notably different from those encountered in Florida, and this is reflected in the mix of disciplines and experience offered by Geosyntec practitioners in these locations and at a multitude of others around the world. Likewise, our clients are equally diverse, ranging from municipalities and water utilities to private companies that require water supply for industrial uses or to provide bottled drinking water. Geosyntec's scientists, engineers, and permitting specialists provide clients with integrated solutions based on decades of experience that balance the needs for water supply development and ecological health. We also provide clients a thorough understanding of their specific water cycle, allowing them to optimize their system performance and to make informed demand management decisions. Our practitioners provide detailed source assessments for both surface water and groundwater, identifying potential issues regarding water rights, water quality, and reliability. We perform robust alternatives analyses that present clients with a comprehensive understanding of the potential impacts associated with diversions from a surface water body, extraction from a groundwater aquifer, or the interaction of groundwater and surface water. We also engage with clients to develop a complete understanding of their needs and regulatory requirements related to consistent water delivery for their communities or industrial purposes. Armed with this knowledge, we frequently design production wells, diversion facilities, piping systems, and instrumentation networks that exceed expectations and allow clients to meet water supply needs. In addition, many of Geosyntec's clients have aging water supply systems and infrastructure that show clear signs of decreasing performance. We work closely with such clients using tools ranging from geophysical analysis of their conveyance systems to optimization modeling of their well fields and diversion facilities to ensure water supply systems operate at maximum efficiency.

Spring Water Supply Systems

Geosyntec provides a wide range of specialized services in the areas of water resources, water supply development, and water conservation throughout the world. Designing effective and sustainable solutions that identify and address issues related to surface water and groundwater supplies can be complex, frequently requiring a multidisciplinary approach. Geosyntec's scientists, engineers, and permitting specialists provide clients with integrated solutions based on decades of experience that balance the needs for water supply development and ecological health. Our practitioners offer a wide range of services that include most elements of water supply development — from initial source analyses, water quality evaluation, and water rights investigations through permitting and design of treatment and conveyance systems to construction management. We consult closely with clients to ensure a thorough understanding of their specific water cycle, allowing them to optimize their system performance and to make informed demand management decisions about their supplies of available water. In just one example, we provide comprehensive water supply services to Nestlé Water North America (NWNA), the largest bottler of spring water in the United States, for their operations in Zephyrhills, Florida. As NWNA's primary water resources contractor in Florida, Geosyntec ensures the client maintains sustainable yields from the natural groundwater system. We initially provided hydrologic studies to determine a spring's safe yield, conducted capture zone analysis, and evaluated other nearby water supplies. We have also provided design, construction oversight, and permitting services for installation of NWNA's production wells at a number of Florida locations, including a bottling plant, a spring site, and a spring water bulk loading facility. During installation of the wells, we monitored water quality parameters to ensure the geochemistry of the production water meets the strict standards of quality set by NWNA. For these sites, we also prepared a Standard of Identity report, which is required by the U.S. Food and Drug Administration in order to approve the wells for bottled spring water. This report exhibits that the production well is connected hydraulically to the spring and also shares identical water chemistry with the spring. Geosyntec was instrumental in obtaining approval in all states where approval was sought. At these sources, Geosyntec currently performs all sampling and reporting requirements identified by the permit, including groundwater sampling and water quality and level reporting.
