Turbidity is a crucial indicator of drinking water quality, significantly impacting both aesthetics and public health by signaling the potential presence of waterborne pathogens. In various applications, from assessing natural water sources for aquatic life compatibility to verifying wastewater treatment efficacy, controlling and monitoring turbidity remains paramount for regulatory compliance. This optical property, driven by suspended solids, describes how light is scattered and absorbed, with higher turbidity indicating greater light dispersion. Even the purest liquids exhibit some light scattering, meaning achieving absolute zero turbidity is practically impossible.
Drinking water treatment facilities utilizing surface water, such as lakes and rivers, are mandated by the EPA to continuously monitor and report turbidity levels. The EPA Method 180.1 establishes strict criteria for nephelometers and outlines specific reporting requirements, including an applicable range of 0-40 NTU, a tungsten lamp light source, a maximum 10 cm light path, and a 90° detector with a spectral peak response between 400 nm and 600 nm. The instrument must also possess the sensitivity to detect turbidity differences of 0.02 NTU or less in low turbidity waters.
