Our expertise includes:
- Planning, design, and construction of water towers, wells, distribution systems, treatment plants, and pumping/booster stations
- Assistance with securing discharge permits, modifications and renewals
- Collection system maintenance and rehabilitation
- Master plan development

Wells/wellfields
Geo-Logic Associates provides comprehensive well and wellfield services, from hydrogeologic investigations through design, testing, construction oversight, and long-term asset management. Our team helps clients develop reliable water supplies while maximizing system performance and regulatory compliance. Expertise includes:
- Water supply development services, including site suitability assessments, exploratory drilling and hydrogeologic characterization, well design, aquifer testing, conjunctive use studies, and water quality assessments
- Providing pre- and post-design construction quality assurance (CQA) services, including developing specifications and providing bidding assistance
- Zone-specific characterization of aquifer hydrologic properties and water quality using packer tests and/or temporary wells.
- Geophysical logging oversight and analysis, including detailed lithologic descriptions and interpretations using innovative techniques

Water storage distribution systems
We help clients evaluate, plan, and design water storage and distribution infrastructure that supports reliable service, future growth, and system resilience. Our engineers use advanced modeling and practical engineering solutions to optimize system performance.
Groundwater recharge/reuse
Geo-Logic Associates is recognized nationally for its expertise in aquifer storage and recovery (ASR), managed aquifer recharge (MAR), and water reuse. We help clients develop sustainable strategies that increase water availability while successfully navigating evolving regulatory requirements.

- Performing low-impact development (LID) studies
Numerical modeling
Our modelers develop analytical and numerical tools that help clients understand complex water systems, evaluate alternatives, and make informed resource management decisions. We apply industry-leading approaches ranging from conceptual analyses to advanced predictive modeling. We offer a wide-range of modeling services, including:

- Geologic modeling and 3D visualization
- Scenario analysis to evaluate and rank multiple project alternatives to identify which is most likely to provide the best return on investment based on project goals
- Evaluation of potential impacts from future climate change on basin or system resiliency and sustainability
Watershed management
Geo-Logic Associates helps clients protect and restore watersheds through science-based planning, risk assessment, and resource management strategies. Our work supports water quality protection, ecosystem health, and resilience to wildfire and climate-related impacts. Our expertise includes:

Data management
Our database management system (DBMS or DMS), GLA-Data, helps organizations efficiently manage, analyze, and visualize large environmental datasets. The web-based system supports groundwater management, monitoring programs, regulatory compliance, and public transparency initiatives. A subset of GLA-Data applications and general functionality are provided below:
- Sustainable Groundwater Management Act (SGMA) Application: Developed specifically to support implementation of California’s Sustainable Groundwater Management Act (SGMA), this application provides map-based visualization of monitoring points (wells, steam gages, weather stations, etc.), interactive tables and graphs of time series data (water levels, water quality, production, etc.), and numerous other tools for Groundwater Sustainability Agencies (GSAs) to efficiently utilize the vast quantity of data available at the groundwater basin scale
- Groundwater Banking Application: Developed to support complex groundwater banking operations by tracking physical water, the legal right to water (i.e., “paper water”), and the costs associated with operating a water bank (purchase, transport, recharge, extraction, etc.) across multiple basins and agencies
- Emerging Contaminants Program Application: Developed to support the New Mexico Environment Department’s (NMED) Emerging Contaminants Program (ECP), this application provides public access to the data used in ECP’s initial monitoring effort and supports transparency by enabling users to easily view results across geography and analytes
- Solid Waste Application: Developed to support our solid waste clients, this application contains several water quality focused features such as automated generation of publication-ready figures (hydrographs, analyte time series, piper diagrams, stiff diagrams etc.) and formatted tables
- Utility Asset Management Application: Developed to support large (>50,000 population) water utility clients meet the requirement to make their water service line inventory publicly available, this application provides customers with the ability to see what materials their service line is made of by providing their address, account number, or simply navigating to their house using the map provided
