Well characteristics
Across the wells Mark's Water Well Service, Inc. has drilled, the median depth is 120 ft (middle half 100 ft–155 ft), median tested yield 20 gpm, and median static water level 80 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.
"Records span 2005–2026" refers to the earliest and latest well logs attributed to this company in the TDLR/TWDB database — the state digitized older paper logs, so the first date is the oldest record on file, not necessarily the company's founding year.
