Phase 1 SBIR

Agency: Environmental Protection Agency
Topic: 2003
Budget: 01/01/03 - 12/31/03

Subsurface treatment for arsenic removal (STAR) is an innovative technology for treatment of arsenic in groundwater at the wellhead. The STAR technology can result in large cost savings when compared with conventional above-ground treatment methods. The goal is to create a subsurface biogeochemical barrier composed of reactive iron hydroxide m...

Agency: Department of Agriculture
Topic: 2001
Budget: 01/01/01 - 12/31/01

We have developed a novel siphon-infiltration trench system to mange water and sediment budgets in riparian systems. We have demonstrated in the laboratory and developed a numerical model showing the three hydrologically-distinct flow regimes in a infiltrating siphon system: 1) infiltrating flow at low-flow rates, 2) cycling outflow at intermedi...

VERTICAL SATURATED HYDRAULIC CONDUCTIVITY OF SOIL ABOVE A DEEP WATER TABLE IS ONE OF THE MOST IMPORTANT CHARACTERISTICS GOVERNING FLOW AND TRANSPORT. THIS PARAMETER IS USED IN WATER BALANCE STUDIES OF CROP PRODUCTION, IRRIGATION AND DRAINAGE SYSTEM DESIGN, RANGELANDAND FOREST WATERSHED MANAGEMENT, SOIL CONTAMINATION ASSESSMENTS, AND REMEDIAL ACT...
