BOD

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.

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.

Buffering Capacity

The ability of a solution to neutralize acids without a significant change in pH. Buffering capacity is also known as alkalinity and is measured in mg/L of equivalent CaCO3, a common buffer.

Bulk Water-Hauling System

A public water system that provides water piped into a carrier vehicle and withdrawn by a similar means into the user's storage facility or vessel. The term includes, but is not limited to, the source of water, treatment, storage or distribution facilities. The term does not include a public water system that provides only a source of water supply for a bulk water hauling system.
