These groups are <br />identified using a common letter in the container column: (a), (b), (c) or (d). Sample volumes should <br />always be verified with the laboratory prior to sample collection. <br />2 <br />pH, Temperature, Electrical Conductivity, Dissolved Oxygen, and Oxidation-Reduction Potential <br />should be measured immediately in the field. <br />3 Standard Cations include calcium, magnesium, sodium and potassium. <br />4 <br />Standard Anions include Chloride and Sulfate. <br />5 <br />EPA Method 8260B is for solid waste; the equivalent method for water is EPA Method 524.2.
