SAMPLING SAVVY

摘要

The Hampton Roads Sanitation District (HRSD; Virginia Beach, Va.) completed a hydrogen sulfide baseline monitoring program throughout its interceptor sewer system as part of a consent decree requirement. The program sought to establish relationships between hydrogen sulfide in the wastestream and internal collection systems corrosion so that HRSD can prevent or minimize odor complaints, protect assets against corrosion, and minimize health and safety concerns related to hydrogen sulfide. The program involved collecting headspace gas samples and testing the dissolved oxygen (DO) content of the water in the interceptors.
