Drill spoils that are higher in density with more drill solids require lower dosages. Once you've calculated the correct dosage, it can be poured into or across the surface of a waste slurry pit and stirred into it with a backhoe, excavator, or soil mixing equip- ment such as pug mills. Dugan recommends allowing the Slurrybond to sit for at least 24 hours to fully hydrate. The time it takes to hydrate is one reason Traut chooses not to solidify drilling spoils right now. "I didn't want to sit there and wait for it," he says. "It's kind of like making Jell-O. Do I want to sit and watch it (solidify)? No." Slurrybond 200 is a faster acting product that requires less to be shipped to the job site, but it comes with a tradeoff, Dugan says. It's more expensive. Obviously, solidification won't always be the best option. The simplest and cheapest solution may even change from job to job. But, in Dugan's opinion, solidification is worth looking into as more and more states add laws limiting the disposal of drilling spoils. For now, Traut considers himself fortunate to live in an area where disposing of drilling spoils isn't much of an issue—but he knows it could be someday. "Right now we're not faced with (tough regulations), yet," he says. "But it's probably coming." WWJ Material after it has processed through a machine that introduces the solidification reagent will be a dry solid in less than five minutes.
