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.)
