What Hydrosource Associates does

HydroSource Associates, Inc. (HSA) is a privately held U.S. professional services firm specializing in the exploration, development, and management of groundwater resources. Founded in 1991 and headquartered in Ashland, New Hampshire, with a regional office in Greenville, South Carolina, the firm serves national and municipal water authorities, countywide water authorities, private water companies, food processing operations, power plants, destination resorts, dairy farms, and bulk water suppliers for the beverage industry. HSA reports project work across the United States and internationally in the Caribbean, South America, China, Southern Africa, the Horn of Africa, and the Middle East, and states it has developed tens of millions of gallons per day of groundwater supplies for clients over its history.

The firm's core technical platform is a multi-method groundwater exploration and development methodology that integrates remotely sensed data (enhanced satellite imagery, side-looking airborne radar mosaics, color infrared and black-and-white aerial photos, digital elevation models), first-rate geologic field investigations, and an extensive suite of geophysical surveys (electrical resistivity, magnetometry, electromagnetometry, very low frequency electromagnetometry, micro-gravimetry, CSAMT, ground penetrating radar). HSA pioneered the exploration and development of high-yielding water wells in fractured crystalline bedrock and has extended its methods to karst, complex volcanic, and alluvial environments. Service lines span Groundwater Exploration and Development, Groundwater Supply Analyses, Fracture Trace (Lineament) Analyses, Geophysical Surveys, Wellfield Development and Management, and Advanced Groundwater Development and Management (including aquifer storage and recovery, fractured bedrock seawater intakes for desalination plants, riverbank filtration, and angled wells).

HSA generates revenue through project-based professional services engagements sold directly to enterprise and government technical decision-makers via an enterprise field sales motion. Pricing is not publicly disclosed; each engagement is scoped and quoted individually based on client requirements. The firm operates with 1–10 employees and is independently held with no disclosed external investment, parent company, or acquisition history in the source material.

Core offering

HydroSource Associates (HSA) is a specialized consulting firm that explores, develops, and manages groundwater resources for public and private clients. The company locates sustainable groundwater supplies using a systematic combination of remotely sensed data (satellite and airborne imagery), geologic field investigations, multiple geophysical survey methods, digital elevation models, and groundwater recharge analyses, and also delivers wellfield development, drilling oversight, well rehabilitation, regulatory permitting support, and long-term Water Management Plans.

Product overview

HydroSource Associates is a groundwater exploration, development, and management consultancy that operates as a single integrated service platform rather than a software product company. The company offers six interconnected service areas: Groundwater Exploration and Development (using remote sensing, geophysics, and field investigation), Groundwater Supply Analyses (modeling and recharge analysis), Fracture Trace Analyses (satellite and radar imagery), Geophysical Surveys (multiple survey methods), Wellfield Development and Management (operations and regulatory support), and Advanced Groundwater Development (ASR, RBF, seawater intakes, and angled drilling). These services work together to provide clients with complete water supply solutions from initial exploration through long-term management.

Functional benefit

Products and services

• Groundwater Exploration and Development Comprehensive groundwater exploration services using satellite imagery, geologic field investigations, geophysical surveys, digital elevation models, and recharge analyses to locate and develop sustainable water supplies for public/private water systems and planned commercial and industrial parks.
• Groundwater Supply Analyses Analysis services including recharge analysis and groundwater modeling to assess sustainable yield and supply capacity of identified groundwater sources.
• Fracture Trace (Lineament) Analyses Analysis of enhanced satellite imagery, side-looking airborne radar mosaics, colored infrared and black/white aerial photos, stereo pairs, and digital elevation models to identify fracture systems for optimal well siting, especially in fractured crystalline bedrock.
• Geophysical Surveys Field geophysical surveys including electrical resistivity, magnetometry, electromagnetometry (EM), very low frequency (VLF), micro-gravimetry and gravimetry, controlled-source audio-frequency magneto-telluric (CSAMT), seismic, self-potential, magnetotelluric, and ground penetrating radar (GPR).
• Wellfield Development and Management Full-service wellfield management including operation plans, small system operation and management, groundwater/surface water integration, constant-rate and long-term pumping tests, regulatory permitting, down-hole video analysis, well rehabilitation, and water treatment alternatives for naturally occurring contaminants.
• Advanced Groundwater Development and Management Specialized services including aquifer storage and recovery (ASR), fractured bedrock seawater intakes for desalination plants, riverbank filtration (RBF), and angled well drilling.
