Biochemical Oxygen Demand
Microrganisms growing and reproducing in a controlled environment are used to partially stabilize (oxidize) organic matter.
Nutrient-rich organic material that are produced from the stabilization of sewage sludge and residential septage that meets specific quality criteria and are suitable for land application.
Biosolids (Exceptional Quality)
Biosolids that meet stricter pollutant and pathogen reduction criteria.
Biosolids (Non-Exceptional Quality)
Non-exceptional quality biosolids are biosolids that meet specified pollutant and pathogen reduction criteria. Criteria for non-exceptional quality biosolids are less stringent than criteria for exceptional quality biosolids.
Note: The term 'Biosolids' can be used to refer to all categories of biosolids collectively, or can be used to refer specifically to the category non-exceptional quality biosolids.
BOD — Biochemical Oxygen Demand
A measure of the oxygen required to break down organic materials in water using biological means. The amount of oxygen required to oxidize any organic matter present in water during a specified period of time, usually 5 days. It is an indirect measure of the amount of organic matter present in water that is used to monitor natural waters and processed effluents discharged into natural waters.
Water is treated with an additional boost of chlorine from within the distribution system.
Bottled Water System
A public water system that provides water for bottling in sealed bottles or other sealed containers. The term includes, but is not limited to, the sources of water and treatment, storage, bottling, manufacturing and distribution facilities. The term does not include a public water system that provides only a source of water supply for a bottled water system and excludes an entity providing only transportation, distribution or sale of bottled water in sealed bottles or other sealed containers.
