Details: I sent an email to Langdon Lake on 9/24/25. The coliform sample collected on 9/22 tested positive for total coliform bacteria. Three repeat samples and a triggered source sample from the Betty Lou spring is needed by 10/3. Then three routine samples are needed in October. Further action may be needed based on the results.
