Ambient Monitoring

Hydrogen sulfide monitoring at Pier 2 occurs only during prilled sulfur loading events. The Port uses deployable instrumentation to measure levels of hydrogen sulfide. The instrumentation automatically reports any exceedances or issues to appropriate Port staff via email and text message. Monitoring results are updated daily on this page.
