Section 32.70 - Sampling and Analysis Requirements(1)General. Each sample of sludge, septage, or soil shall be sampled, handled and analyzed in accordance with best technical judgment, with guidance most recently published by the Department and the EPA, and with 310 CMR 32.70.(2)Sampling. Each sample shall be sampled in compliance with all of the following requirements: (a) The sample shall be collected in a proper manner to ensure that it is representative of the material being sampled.(b) The sample shall be properly preserved immediately upon collection.(c) The sample shall be properly handled and packaged in a manner that will maintain the integrity of the sample and minimize the potential for contamination.(d) The sample shall be labelled to show when, from what, from where, and by whom it was taken.(e) As soon as possible after it is collected, and in any event no later than its maximum holding time for reliable analysis, the sample shall be delivered to the laboratory for analysis.(3)Laboratories.(a) Each sample analyzed for the purpose of complying with 310 CMR 32.00 shall be analyzed only by a laboratory deemed acceptable by the Department for that purpose.(b) Each laboratory wishing to be deemed acceptable, or to continue being deemed acceptable, to the Department pursuant to 310 CMR 32.70(3)(a) shall provide to the Department a description of the quality control procedures which the laboratory uses to verify the validity of analysis results.(c) No laboratory shall analyze any sample by using an analysis method not previously accepted by the Department, or by deviating from an analysis method previously accepted by the Department unless the deviation has previously been accepted by the Department.(4)Analysis. The following analysis methods may be used: (a) Generally. 1.Manual of Methods for Chemical Analysis of Water and Wastes, EPA, 1983 (or the most recent edition at the time the sample is analyzed).2.Standard Methods for Examination of Water and Wastewater, american Public Health Assoc. (Whatever edition is most recent at the time the sample is analyzed.)3.Test Methods for Evaluation Solid Waste, physical/Chemical Methods, EPA S.W.-846, 1980 (or most recent edition at time the sample is analyzed).4.

L. Page et al, american Society of Agronomy, madison, wisconsin, 1982. Specifically, 1.1. If the pH of the soil is below 7.0, the cation exchange capacity shall be determined by using the summation of exchangeable basis and exchangeable acidity methods, paragraphs nos. 58-2 and 59-3, respectively, of said monograph.2.2. If the soil is neutral, calcareous, or saline, the cation exchange capacity shall be determined by the sodium acetate method, paragraph no. 57-3 of said monograph.(c) For cadmium, Sampling and Analysis of Soils, plants, wastewater, and Sludge. Suggested Standarization and Methodology. North Central Region Publication 230, Research Publication 170.(d) For PCBs, 1. In waste material, milk, and animal feed, the method recommended from time to time by the Association of Official Analytical Chemists.2. In milk and animal feed, any method recommended from time to time by the U.S. Food and Drug Administration.(5)Reporting Analysis Results. The results of each analysis submitted to the Department pursuant to 310 CMR 32.00 shall include, to the extent applicable, the reference citation of the method used for the analysis, including all deviations from such method.
