Well characteristics

Across the wells American Construction And Supply Inc. has drilled, the median depth is 200 ft (middle half 100 ft–300 ft), median tested yield 4 gpm, and median static water level 30 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1989–2026" 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.
