Applications of A-SOX include

  • Stimulation of anaerobic biodegradation of groundwater contaminants in ground water wells through controlled release of carbon, ZVI, and nutrient delivery using EHC.
  • This is not an aggresive treatment but, rather, an enhancement to natural attenuation. Ideal for sites where there are either residual, or a thin layer of contaminants.
  • The radius of influence depends on the hydrogeology of the site but is still predictably small (in the order of 10 ft radially, 20-50 ft downgradient).


EHC is an integrated source of slow-release oxygen combined with nutrients and a pH buffering agent to provide the ideal conditions for rapid bioremediation of organic and inorganic soil, sediment and groundwater contaminants. For organic constituents, EHC significantly stimulates catabolic activity of indigenous microflora further accelerating the rate of contaminant removal. EHC not only eliminates contaminants quickly —but also guarantees appreciable cost savings over other oxygenrelease products on the market. EHC’s proprietary technology is field proven and available today.

A-SOX is a delivery mechanism consisting of a fabric sleeve (or sock) filled with EHC and a stainless steel canister. For ease of use in groundwater wells, the socks are lowered in the well inside reusable stainless steel canisters. The number of canisters that can be hooked together is limited and governed by well screen length, weight, and the fact that they all need to be submerged.

A-SOX is available in two nominal sizes: 2 x 36 in and 4 x 36 in.

A-SOX sleeves and stainless steel canister

A-SOX sleeves and stainless steel canister available in 2" and 4" sizes. Socks are stored and shipped in pails.
