Abstract
An estimated half million households in Minnesota are not connected to public sewer systems.
Along with the growing use and expansion of lakeshore cabins and resorts, many have the
potential to degrade surface and groundwater resources as they depend primarily on individual
sewage treatment systems (ISTSs) for the treatment and dispersal of domestic wastewater.
Unfortunately, many are in noncompliance with state standards or are hydraulically failing to the
surface. Effective treatment options are needed for the thousands of locations with restrictive
soil and site conditions. Many of these sites occur along lakes and streams, creating a potential
health hazard to swimmers and others using surface water for drinking water and recreation,
leading to increased algal blooms, aesthetic nuisances and degraded fish habitat.
Packed bed textile filters, coupled with a site-specific soil dispersal system, were one of several
options evaluated in Minnesota. Other systems tested in northeast Minnesota have included sand
filters (single pass and recirculating), peat filters (in-ground and module), subsurface flow
constructed wetlands, aerobic treatment unit, standard trenches, gravel filter and drip distribution
(McCarthy et al., 1997, 1998, 1999, 2001; Anderson and Gustafson, 1998; Henneck et al., 1999,
2001; Axler et al., 1999, 2000; Monson Geerts et al., 2000, 2001; Pundsack et al., 2001;
Christopherson et al., 2001). This paper provides an overview of the operation and performance
of a recirculating packed bed textile filter, polishing sand filter and shallow gravelless trenches at
the northern Minnesota research facility.
