Selenium results
MS0110002 , C S & I Water Assn #1
25 samples have been analysed for Selenium at C S & I Water Assn #1.
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.
