Well characteristics

Across the wells Geotek Engineering & Testing has drilled, the median depth is 17 ft (middle half 15 ft–25 ft), median tested yield —, and median static water level — below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Geotek Engineering & Testing, straight from the public SD DANR record:

"Records span 1989–2026" refers to the earliest and latest well logs attributed to this company in the SD DANR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
