IV ADDITIONAL REGIONAL STAFF REVIEW COMMENTS/ATTACHMENTS (Optional/If Needed)
This review was conducted for a permit renewal request for a geothermal injection well heat pump
system for the Karasek residence. On March 11, 2020, staff visited the home to inspect the well
system. Source well water and water prior to injection were sampled for Metals, Total and Fecal
Coliform, Nitrates, Chloride, Sulfate and Total Dissolved Solids. Sampling results will be forwarded to
the Central Office and owner when received from laboratory. System operation has been normal.
