Well characteristics

Across the wells Jay Gallagher has drilled, the median depth is 320 ft (middle half 260 ft–375 ft), median tested yield 30 gpm, and median static water level 100 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1995–2018" 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.
