Well characteristics

Across the wells Merle "Sam" Dunham, Inc. has drilled, the median depth is 200 ft (middle half 160 ft–240 ft), median tested yield 7 gpm, and median static water level 38 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1908–2011" refers to the earliest and latest well logs attributed to this company in the Maine Geological Survey database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
