Original drilling logs
Recent well logs filed by Ground Water Systems Inc., straight from the public DWR record:
"Records span 1904–2021" 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.
