Measurement Standards Standards for wastewater measurements address the standard test methods, guides, and practices for measuring turbidity, flow, and other properties of wastewater, as well as sampling. Given the focus on testing and measurement, standardization of this field of wastewater management has been greatly contributed to by the efforts of ASTM International, previously known as the American Society for Testing and Materials.

For standards addressing content testing, see our dedicated pages for element specific wastewater measurements, and bacteria, biodegradable content, and toxicity wastewater measurements.
