    Development of Alternative On-site Treatment Systems for Wastewater Treatment: A Demonstration Project for Northern Minnesota
    (University of Minnesota Duluth, 1997-12-31) McCarthy, Barbara J; Axler, Richard P; Monson Geerts, Stephen D; Henneck, Jerald; Crosby, Jeff; Nordman, Del; Weidman, Peter; Hagen, Timothy S; Anderson, James; Gustafson, David; Kadlec, Robert; Otis, Richard; Sabel, Gretchen
    The major objectives at the northern site were 1) to design, construct, monitor and compare the yearround performance of alternative treatment systems, with respect to a conventional trench system, for treatment of typical single family wastewater flows (based on the removal of fecal coliform bacteria, BOD5, TSS, phosphorus, and nitrogen); 2) to compare subsurface water quality at several depths below drainfield trenches receiving discharge water from a conventional (i.e., septic tank) and alternative systems; 3) to design, construct, and monitor the performance of a subsurface drip irrigation system at different depths in the s0il; 4) to design, construct, and monitor the performance of a pressurized sewage treatment system utilizing small diameter pipe and a subsurface flow, constructed wetland treatment system for a .cluster of lakeshore homes on Grand Lake in order to demonstrate that this alternative technology could correct a problem representative of numerous other situations in Minnesota; and 5) to develop a technology transfer plan for effectively communicating the results of this study to the private sector, the public (i.e., potential users), and the appropriate local and state agencies.
