John Shomaker & Associates, Inc. (JSAI), a wholly owned subsidiary of Geo-Logic, is a Platinum Sponsor of the 2026 Annual Salinity Summit. The event is organized by the Multi-State Salinity Coalition (MSSC) and is taking place from February 25 through 27, 2026 in Las Vegas, Nevada. Sessions will focus on salinity management, desalination project implementation strategies and approaches, water/power colocation, addressing regulatory and environmental hurdles, and future strategies to manage desalination and concentrate management. The mission of the Multi-State Salinity Coalition is to meet the growing need in the United States for safe, sustainable, adequate and affordable water supplies, we promote advancements in desalination-related technologies, salinity control strategies and associated policies.
JSAI has been providing professional services in the areas of fresh and brackish water resource development, groundwater flow and solute transport modeling, drilling specifications for large capacity wells, geochemistry, environmental assessment and reclamation, and expert witness testimony for over 50 years. Along with GLA’s hydrogeologists, hydrologists, geochemists, geologists, engineers, and GIS/AutoCAD specialists, we have ongoing projects in Arizona, New Mexico, Texas, Nevada, California, South Dakota, Argentina, Chile, Guatemala, and British Columbia.
Our team has developed drilling specifications for brackish water wells completed in unconfined and confined aquifers; performed hydrogeologic assessments for concentrate disposal wells, and field oversight and data collection for all aspects of drilling, completing, and testing of concentrate disposal wells; and interpreted water quality and hydraulic property test data.
GLA has worked with clients to address issues related to saline groundwater and surface water supplies, including sites where saltwater intrusion had to be evaluated, and aquifers contaminated with brine from oil and gas production. Our experience includes saltwater intrusion modeling, extraction of brackish water for drinking water supplies, and treatment of saline water using reverse osmosis (RO). These projects include the characterization, development and assessment of drinking water sources that were not saline but had marginal total dissolved solids (TDS) concentrations. Many brackish aquifers contain water in this TDS range that can be cost-effectively treated to provide a drinking water supply.
Management of reject water from the desalination process can pose a significant implementation challenge for a desalination program. Disposal methods may include land application or deep re-injection. We have the resources and technical expertise to evaluate brine disposal options and implement a properly designed and permitted waste management program to support desalination operations.
