Well characteristics

Across the wells Coastal Water Well Service has drilled, the median depth is 230 ft (middle half 200 ft–280 ft), median tested yield 6 gpm, and median static water level 55 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 2003–2012" 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.
