BOD Bottle BOD test bottles at the laboratory of a wastewater treatment plant. BOD Bottle or an incubation bottle is a main apparatus used for the Biological Oxygen Demand (BOD) test. During the five-day BOD or BOD5 test process, the BOD bottle is used for incubating diluted samples under the 20 °C or 68 °F of temperature.
BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.
Safe household water storage is a critical component of a Household Water Treatment and Safe Storage (HWTS) system being promoted by the World Health Organization (WHO) worldwide in areas that do not have piped drinking water. In these areas, it is not uncommon for drinking water to be stored in a pot, jar, crock or other container in the home.
Water may be tested by a bioassay comparing survival of an aquatic test species in the wastewater in comparison to water from some other source. [2]: 685–689 Water may also be evaluated to determine the approximate biological population of the wastewater.
EPA poster explaining public water systems and Consumer Confidence Reports. The SDWA requires EPA to issue federal regulations for public water systems. [16] [17] There are no federal regulations covering private drinking water wells, although some state and local governments have issued rules for these wells.
The Safe Drinking Water Act (SDWA) is the primary federal law in the United States intended to ensure safe drinking water for the public. [3] Pursuant to the act, the Environmental Protection Agency (EPA) is required to set standards for drinking water quality and oversee all states, localities, and water suppliers that implement the standards.

Yes, lower BOD indicates better water quality. BOD is an indicator of oxygen-demanding substances in the water body, i.e. pollution. If the substances suck up a lot of oxygen, there's less oxygen available for fish and other critters. Here's a good overview: "Dissolved Oxygen and Biochemical Oxygen Demand" (US EPA). I agree that the beginning ...
