Well characteristics

Across the wells Donald Mccarthy has drilled, the median depth is 300 ft (middle half 225 ft–350 ft), median tested yield 60 gpm, and median static water level 60 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1987–2002" 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.
