Benzene results
MS0730010 , Lake Arrowhead
28 samples have been analysed for Benzene at Lake Arrowhead.
This is one analyte out of the system’s whole record. For what has ever been detected here, and when, see all chemical and radiological results; for everything the system is tested for, see the analyte list.
What counts as a non-detect is defined in the help: Less than Indicator. This system’s violations.
No date range is applied: this list draws on every sample on record. Show the last two years only.
Every Benzene result
The table below lists 1–10 of 28 samples, newest first — collected October 28, 2010 to March 11, 2025.
10 Benzene results from the 10 samples listed here: 0 detected, 10 not detected. Those samples also carried 200 results for other analytes, which are on the full results page.
Units in this table
Benzene is recorded on this page in ug/l and mg/l. 1 mg/l = 1,000 ug/l.
