The Hydrologic Testing and Research Laboratory at Daniel B. Stephens & Associates, Inc. (DBS&A) has been a leading facility for research, development, and implementation of novel technologies and instruments to aide in environmental resource protection and management for over 20 years. DBS&A’s laboratory performs specialized tests for determining the hydrologic properties of soil and rock. Our independent research efforts have led to development and regulatory approval for a simple and cost-saving alternative to standard landfill and hazardous waste covers. DBS&A continues to develop and implement new techniques for soils testing, artificial recharge and passive hydraulic control of contaminants in the subsurface.
