Groundwater Control Treatment Services

The correct equipment is essential to a successful project, but not as important as seasoned operators and project superintendents. RECON employees are among some of the sharpest, hardest-working, and most experienced field personnel in the industry. Operators and project superintendents have an average of 20 years of hands-on experience and are the key to our success with these technologies.

Groundwater Cut-off Walls – RECON has installed over 200 subsurface barriers using the slurry trench method. These cut-off walls have consisted of soil-bentonite, soil-cement-bentonite, cement-bentonite, soil-attapulgite, Impermix, as well as other impermeable materials.

Biopolymer Trenches, Permeable Reactive Barriers, and Iron Filing Walls –RECON has installed over 25 treatment systems using the biopolymer trench method. Trenches have been installed for groundwater intercept, landfill gas intercept, and passive treatment of groundwater.
Reactive Barrier Wall

RECON was awarded a contract to install 7 biotrenches, totaling 2,555 linear feet at the former Naval Weapons Industrial Reserve Plant in McGregor Texas. A biotrench consists of a zone of reactive organic material, installed in the path of a groundwater plume. As biodegradation occurs in the trench, contaminates are reduced to non-hazardous compounds.

• Excavating the 2.5-foot trenches to depths ranging between 10 and 19 feet
• Backfilling the trenches with 60% drain rock, 20% mushroom compost, 20% woodchips, and soybean oil
• Covering the trench with geotextile, a clay cap, and topsoil.
