Casella has developed the new Noise Guardian and Boundary Guardian web-based remote monitoring system, claimed to elevate continuous monitoring of various mining-related emissions to a higher level of simplicity and power.

Users of the system receive real-time email or text messages when noise, dust or vibration levels rise above acceptable levels. According to the company, sound level measurement capability built into the units meets or exceeds usual requirements for accuracy and calculation of important environmental metrics for day/night levels as well as hourly data. The system also provides detailed time-history data that can illustrate noise fluctuations by time so they can be linked to on-site work activities. Reports are accessed in a simple on-screen view—at any time or location—from virtually any PC, tablet or smartphone with a simple, secure login. Formatted management reports are generated with user-defined time periods with as much or as little detail as needed. Data can even be superimposed onto a high-resolution map of the site.

Protected by a compact weatherproof housing, the system’s components are claimed to withstand extremes of both tropical and winter weather conditions. Additional features include easy deployment and minimal maintenance; real-time dust (PM10, PM2.5 or TSP) and noise levels (LAeq, LAFmx); IEC61672-1 compliant sound level measurement for accurate and reliable results; heated inlet to reduce moisture effects; and maintenance-free wind speed and direction sensor (optional). The system also is available in both noise or dust only versions.
