Definitions
Enterococcus
Bacteria found in wastewater and all soil. Enterococcus analysis requires a 24-hour test.
Zone Of Mixing

Deep Ocean Outfall
The structure, approximately 5,000 feet from the shoreline and 105 feet below the water’s surface, that connects the land-based Kailua Regional Wastewater Treatment Plant to the ocean, allowing the discharge of treated water into the marine environment.
CFU (Colony Forming Units) per 100mL
Colony-forming units per 100 milliliters; a measurement of the number of living microorganisms in a liquid, calculated by dividing the number of colonies counted by the sample volume filtered in milliliters and then multiplying by 100.
