IV. ADDITIONAL REGIONAL STAFF REVIEW COMMENTS/ATTACHMENTS (Optional /If Needed)
This review was conducted for an upcoming permit renewal for the geothermal injection well system
serving the Alfano residence. On May 18, 2021, staff visited the home to sample the well system.
Source well water and water prior to re -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.
For future reference for DEQ staff sampling these wells, the injection well sampling port is located
inside the garage and a bucket is needed to catch the purge water. The spigot on the outside of the
garage directly in -line with the well pump can be used for the sample tap of the source well.
Below are pictures of the sampling locations:
