CSE recommends BOD as suitable parameter for water quality, wants equipment approval simplified

Two ways of doing this are using a bio-sensor based system or a spectrophotometer, that give results within minutes and are nearly as accurate as laboratory-based monitoring. That said, conventional laboratory testing must also be made more robust with clear protocols for sampling, transport and testing.
