Original drilling logs

Recent well logs filed by American Construction And Supply Inc., straight from the public DWR record:

"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.
