Remedies purges

Personnel and equipment need to be decontaminated in the CRZ. However, the CRZ might be a small area immediately adjacent to the remediation area, which workers are aware of, and is also marked appropriately. Although the CRZ is less formal and likely does not have many decontamination stations, efforts should be made to make sure that personnel and equipment are appropriately cleaned. Many times, due to the logistics of a smaller job, disposal of wastes becomes difficult. If purge water is drummed and left on the site, it is imperative that it is identified, labeled properly, recorded in the site log, and disposed of in the proper manner (in accordance with applicable, local, state, federal, or other regulations). 

Quick-Purge is a patented, commercially available, in situ technology for the remediation of soil and groundwater contaminated with organic compounds. The technology is primarily used for the remediation of sites contaminated with hydrocarbon constituents associated with diesel fuel, gasoline, kerosene, solvents, and creosote. 

The vendor claims that Quick-Purge costs up to 50% less than traditional remediation methods such as pump-and-treat or soil vacuum extraction (D14386M).

The cost of a vertical Lasagna system was evaluated by DuPont using a cost optimization model. For remediation of TCE to a depth of 40 to 50 ft (12 to 15 m) in clay on a 1-acre (4047-m ) site, costs were estimated to range from 40 to 90/yd ( 52 to 117/m ). Soil properties, depth of contamination, cost of emplacing electrodes and treatment zones, required purge water volume, cleanup time, and cost of electrical power were all included in the estimate (D12500Y, p. 10).

Site investigation and remediation projects usually include the disposal of investigation-derived waste (IDW), for example, soil from cuttings or excavations, equipment decontamination water, purged groundwater from well installation, etc. To determine whether these waste streams may be hazardous, we should consider their source, and, if necessary, chemically characterize the streams for the determination of disposal options. The disposal facility acceptance criteria would be the action levels in this case. 

Misuse of laxatives. It is a widely held belief that at least one bowel movement per day is essential for health yet three bowel evacuations per week is quite normal. The desire for frequent bowel emptying probably stems from the time-honored, albeit mistaken, notion that absorption of colon contents is harmful. Thus, purging has long been part of standard therapeutic practice. Nowadays it is known that intoxication from intestinal substances is impossible as long as the liver functions normally. Nonetheless, purgatives continue to be sold as remedies to cleanse the blood or to rid the body of corrupt humors. ...
