Well characteristics

Across the wells Vironex, Inc. has drilled, the median depth is 20 ft (middle half 8 ft–32 ft), median tested yield , and median static water level 9 ft below ground surface. These summarize the company's own filed logs, not a marketing claim.

"Records span 1995–2014" 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.
