Hydrofracture of a Marcellus shale gas well requires from 3 to 5 million gal of makeup water for every well. Adding SulfaStop to the hydrofracture makeup water eliminates the requirement that the water be low in scale-forming sulfate content. The product has been formulated with food grade and low toxicity components. The 96 hr LC 50 of the product at use levels is greater than 40,000 mg/l.
