AfterShock bioremediation restorative from Cape Cod Biochemical Co. is designed to restore drainage to clogged and sluggish drainfields, cesspools and seepage pits, while preventing backups and eliminating odors. It contains naturally occurring, USDA-approved bacteria that biologically digest the solid material that normally clogs soil absorption areas, as well as a bacteria-friendly, time-release oxidizer that accelerates the bacterial activity. It is effective in residential and commercial applications, and ideal for use in conjunction with high-pressure waterjetting and soil fracturing equipment. It can be applied in one day, eliminating the need to keep the system exposed for repeated site visits. 800/343-8007; www.septiconline.com.
