Well characteristics
Across the wells Martin Pump & Supply Inc. has drilled, the median depth is 160 ft (middle half 127 ft–220 ft), median tested yield —, and median static water level 54 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 1933–2026" refers to the earliest and latest well logs attributed to this company in the DWR database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
