This method describes the determination of the degree of transparency (or turbidity) of water and is primarily employed for on-site measurements.
Water intended for use as an ingredient in the production of beer (brewing liquor) or other foods
This method describes how to determine the clarity or turbidity of water using a turbidimeter.

A water sample containing undissolved substances diminishes the incident light radiation and scatters it unevenly in all directions. The intensity of the scattered radiation depends on the wavelength of the incident light, on the measurement angle and on the form and size of the suspended particles. The results of the turbidimetric analysis are related to a “standard formazin turbidity”.
This method describes how to determine the clarity or turbidity of water using a transparent cylinder.

Separation using ion chromatography and subsequent conductivity detection (of other anions as well)
The PAH compounds are concentrated through extraction with cyclohexane and evaporation. The separation is carried out by means of high-performance thin-layer chromatography. The results are evaluated through examination under UV light, followed by comparison of the Rf values with the reference substances.
The method describes how to determine the content of benzo-(a)-pyrene in drinking water using high performance liquid chromatography.
