Toxicity and Bacteria Standards Standards for testing wastewater for bacteria, toxicity, and biodegradable material specify test and screening methods. Detailing the scenarios in which a particular test is applicable, as well as the sampling and scale elements of a test, these standards address the detection and enumeration of multiple types of bacteria, as well as both the effects of wastewater on bacteria and the effects of the bacteria on larger forms of life.
