What John Shomaker & Associates does

John Shomaker & Associates, Inc. (JSAI) is a professional hydrogeologic consulting firm founded in 1976 and headquartered in Albuquerque, New Mexico. Since 2025, JSAI has operated as a wholly owned subsidiary of Geo-Logic Associates, an employee-owned multidisciplinary environmental, civil, and geotechnical engineering consulting firm with more than 400 employees across 30 offices. The firm provides eight integrated service areas: groundwater development (well site selection, design, drilling oversight, pumping tests, rehabilitation), water-resource and water-rights assessment (groundwater-flow modeling, water balance, recharge studies), geochemistry (contaminant-transport modeling, water quality evaluation), mining hydrology (pit dewatering, water balance, groundwater capture systems), geologic services (mapping, hydrogeologic conceptual models), environmental services (monitoring, UST investigation, wellhead protection), education (short courses on wells and hydrogeology), and expert witness testimony.

JSAI's core technology is built around numerical groundwater-flow and solute-transport modeling, integrated surface-water–groundwater flow models, hydrogeologic conceptual modeling, and geochemical/contaminant-transport modeling. These capabilities are applied at scales ranging from individual well fields to basin-wide regional systems, supporting water-rights applications, environmental impact statements, mining operations, and Superfund remediation. The firm maintains significant expertise in New Mexico water law, western water administration, and interstate compacts, underpinned by principal-level testimony experience in more than 60 judicial and regulatory proceedings.

The business operates on a fee-for-service professional consulting model, generating revenue through project-based contracts with federal and state agencies, counties, communities, tribes, water utilities, water users associations, mining companies, private companies, and individuals. Pricing is quote-based, determined by project scope, complexity, and duration, with no publicly disclosed rate cards. Client engagements span New Mexico, the broader Western United States, and international locations including Argentina, Chile, Canada, and Pakistan. GTM motion is direct and relationship-based, with principals and senior staff leveraging 20+ years of individual experience (150+ years combined) to secure and deliver engagements, supplemented by conference presentations, professional publications, and educational short courses.
