    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.

    Freeze Survey Summary Report: Onsite Wastewater Treatment Systems
    (University of Minnesota Duluth, 2001-03) Reed, Jane; McCarthy, Barbara J; Henneck, Jerald; Axler, Richard P; Crosby, Jeff; Bauman, Heidi
    This report summarizes the results of an informal survey mailed to pumpers and contractors of onsite wastewater treatment systems in northern Minnesota in the spring of 2000. The survey was developed jointly by the Sewage Technical Committee (TC) of the Iron Range Resources and Rehabilitation Board and Northern Lights Tourism Alliance (IRRRB/NLTA). The purpose of the survey was to determine, in general, the types of freezing problems associated with onsite systems during the winter of 1999-2000.
