Here is a use objective for a chemical analysis to be performed at a drinking water purification plant: "Data and results collected quarterly shall be used to determine whether the concentrations of haloacetates in the treated water demonstrate compliance with the levels set by the Stage 1 Disinfection By-products Rule using Method 552.2" (a specification that sets precision, accuracy, and other requirements). Which one of the following questions best summarizes the meaning of the use objective?
(a) Are haloacetate concentrations known within specified precision and accuracy?
(b) Are any haloacetates detectable in the water?
(c) Do any haloacetate concentrations exceed the regulatory limit?
