    Burntside Lodge Wastewater Treatment System Monitoring Report Summer 1996 and 1997
    (University of Minnesota Duluth, 1998-03) McCarthy, Barbara J; Monson Geerts, Stephen D
    The treatment and dispersal of domestic wastewater from resorts are a significant issue in northeast Minnesota due to restrictive site and soil conditions. Within the Iron Range Resources & Rehabilitation Board (IRRRB) service area (Taconite Tax Relief Area), there are approximately 400 resorts that depend on onsite wastewater treatment systems. Of these, it is estimated that 200 resorts are likely to be in non-compliance with state rules (Minnesota Rules Chapter 7080). Two pilot projects were initiated in 1995 within the IRRRB service area to demonstrate the use of alternative wastewater treatment technologies for resorts with difficult site conditions. This project is a cooperative effort between the IRRRB, Northern Lights Tourism Alliance (NLTA), counties within the IRRRB service area, the Natural Resources Research Institute (NRRI), University of Minnesota-Duluth, and Ayres Associates Inc. The wastewater treatment systems for the first pilot projects were constructed in 1996 at Burntside Lodge and at Dodge's Log Lodges. This report summarizes the water quality performance data from the Burntside Lodge wastewater treatment system that operated successfully during the summers of 1996 and 1997.

    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.
