The effectiveness of the Waterloo Multilevel System is proven by its ability to accurately and repeatedly obtain pressure and groundwater chemistry data from several distinct zones in a single borehole. The data set below shows a decrease in Total BTEX contamination due to ongoing pump and treat operations at an oil pipeline leak.
Underground oil pipeline leak assessment. Three 150 ft. (45 m) installations. Two point rising head permeability tests were conducted in each interval of the Waterloo Multilevel System. (See diagram showing contaminant distribution above.)
