Best percolation testing pros near Stillwater, MN

Arrived on time. Quality of work seems fine, though the true test will be time. The price seemed high and the technician struggled to explain/justify the costs. Technician suffered from women-who-ask-questions-annoy-me syndrome. Not a terrible experience, but left a bad taste in my mouth.
