Cross-connection survey in Calhoun County, Michigan

Abstract

"The object of the survey was to locate such cross-connections as existed in a typical county and to determine the extent to which these constitute potential health hazards. A cross section of the area was surveyed to estimate the total number of such connections which were present, to find out how the correction of these hazards should fit in with a public health program, and finally, to design a procedure for the elimination of the dangerous connections found."--Page 4.
