Well characteristics

Across the wells Simpson has drilled, the median depth is 94 ft (middle half 53 ft–160 ft), median tested yield 10 gpm, and median static water level 26 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

Original drilling logs

Recent well logs filed by Simpson, straight from the public MBMG record:

"Records span 1936–1978" refers to the earliest and latest well logs attributed to this company in the MBMG database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
