"Environmental Protection Service report series." "December 1978." Digitized edition from print [produced by Environment and Climate Change Canada]. "A laboratory evaluation of the petroleum leak detection device, Leak "X", was performed to evaluate the response times to various petroleum products. Response times of one to two hours were found for gasoline and overhead naphtha. In diesel fuel, response times varied from three to nineteen hours, depending on the temperature. In crude oil, the reaction time varied from two hours to several days, depending on the type of cable used and the temperature. Tests conducted in various types of soils showed that in impervious clays and silts the reaction time is two to three times slower than in sands or gravels. Preliminary evaluation of weathering effects on the detection cable were performed and it was concluded that long-term evaluation of weathering effects on the cable should be performed"--Abstract.
