Intensive Septic System Research

Principal Investigator:

Sara Heger

Project Summary:

This proposal is an addition to current research between the University of Minnesota (UM) Onsite Sewage Treatment Program and the Minnesota Department of Transportation (MnDOT) Water Services Unit. During the evaluation of the MnDOT septic system facilities numerous additional research areas arose which will be evaluated in this project. The first objective will be continuation and expansion of automated field-based verification of groundwater mounding and water levels to estimate the influence of larger wastewater treatment systems on groundwater systems. The second objective will be evaluate chemicals of emerging concern from three to five safety rest areas and one land application site. The next objective will characterize and compare the microcrobial communities among soil treatment areas and unaltered soils from the same site. The last objective will develop a reuse system design along with plans and specifications for truck wash down water at the Arden Hills Truck station for brine production.
