The accuracy and precision of two field methods and a laboratory method for determining detergent (alkylbenzenesulfonate) in water have been investigated. Commercially available kits were used for the field methods. A total of 660 determinations were made by two analysts on prepared solutions containing both branched‐chain and straight‐chain detergents. One of the field methods contains large amounts of negative bias that vary with concentration level. The other field method has poorer precision than the laboratory method but no large amount of bias.
