Well characteristics

Across the wells Gary D Thompson has drilled, the median depth is 280 ft (middle half 240 ft–363 ft), median tested yield 30 gpm, and median static water level 130 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1986–1995" refers to the earliest and latest well logs attributed to this company in the MoDNR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
