Maximum holding times (MHTs) have been established by the U.S. Environmental Protection Agency (EPA) and have been

    Sample Containers, Preservation, and Holding Times: Sample Holding Times . For most samples, the Safe Drinking Water Act states to use the holding times listed in 40 CFR 136. As with sample containers and preservation techniques, maximum holding times are specified in federal regulations. Once samples are collected and properly preserved, they As more data become available, these recommended holding times will be adjusted to reflect new information. Other information provided in the table is an estimation of the volume of sample required for the analysis, the suggested type of container, and the maximum recommended holding times for samples properly preserved.

    Sample Preservation Refer to the previous pages for specific preservation requirements. Holding times start at time of sampling for grab samples and end of composite period for composites. 4 Testing for dissolved metals requires filtration (0.45 micron) prior to preservation. Immediate filtration and preservation in the field is preferred. Sample holding times are determined by the analytical method. Holding times are noted in Figure 3. Samples received after the holding time has expired are analyzed only under direct request from the client. Appropriate sample and/or data qualifiers are noted on the final report, as applicable (Appendix J). Preservation Techniques Proper
