Well characteristics
Across the wells Andrew Harper has drilled, the median depth is 1,100 ft (middle half 566 ft–1,374 ft), median tested yield 500 gpm, and median static water level 205 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1995–2025" 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.
