AfterShock soil absorption restorative from Cape Cod Biochemical Company is designed to restore drainage to clogged and sluggish drainfields and drainage structures by biologically digesting the solid material that normally clogs soil absorption areas. It contains naturally occurring, USDA-approved multi-strain bacteria, as well as a bacteria-friendly, time-released oxygen source that accelerates the bacterial metabolism. It is nonhazardous, nontoxic, contains no U.S. EPA Priority Pollutants, and it is safe for the environment. It can be used in residential and commercial drainfields, cesspools and seepage pits, and in conjunction with high-pressure waterjetting and soil fracturing equipment. Its consortium of bacteria and oxidizer can be applied at the same time, eliminating the need to keep the system exposed for repeated site visits. 800/343-8007; www.septiconline.com.
