Pilot plant research conducted in 1974 at Duluth, Minnesota, demonstrate that asbestiform fiber counts in Lake Superior water could be effectively reduced by municipal filtration plants. During the study, engineering data were also obtained for making cost estimates for construction and operation of both granular and diatomaceous earth (DE) filtration plants ranging in size from 0.03 to 30 mgd. During the pilot plant research, three different turbidimeters were utilized in order to compare 90 degrees scatter instrumentation with 15 degrees forward scatter instrumentation. The data from this comparative study are in Appendix H.
