The University of Minnesota Onsite Sewage Treatment Program assessed a residential septic system in Minnesota owned by a patient undergoing home hemodialysis treatment for kidney failure to evaluate the wastewater being generated by the household and determine whether the composition of this wastewater has the potential to affect the function of the septic system.
A site assessment and sampling for general wastewater constituents was done and showed higher-than-normal concentrations of total suspended solids at 142 mg/L, total Kjeldahl nitrogen at 132 mg/L and biochemical oxygen demand at 198 mg/L. Chloride and sodium were also found to be at higher-than-normal levels: 1,250
