24 Hour Drager Monitor Results
The 24-hour continuous monitoring system was installed on March 12, 2026, at the landfill site. The system is configured with a low alarm threshold of 10 ppm (A1) and a high alarm threshold of 15 ppm (A2), as detailed in the accompanying data sheets.
Each screenshot diagram displays the actual readings for the specified time period with a blue line. The overview on the screenshot indicates the alarm thresholds and any readings within the time frame. The Excel spreadsheets provide the alarm thresholds and detail the H2S readings, along with any other alarms or warnings.
Notes for March 15 readings: 1. The Logged Value data displays every time the monitor detected a concentration change, regardless of how quickly or often, and the 15-minute time waited average (TWA) in the adjacent column. 2. The 1-Min Avg data displays the average reading over each 60-second period, the same 15-minute TWA column, and a column for both the minimum reading and peak reading during that 60-second period.
