as tittle agitation as possible to reduce potential loss of volattile constituents. Major ions., TDS, and metals analyses (in non-preserved-containers) will be collected next followed by samples t be collected in preserved containers. Containers will be filled directly from the P o disposable bailer, immediately cVped,and planed in a tem monitor):d iced chest. Cau_tion will be used not to ovcrffl bottles containing a PlitSCIVatiW. Temperatura will be nio ° by P iiB a - thermometer in the chest and ch to.make-sure that there is sufficient ice in the chest to mahitain. a temperature Of m app iy 4 degree Celsius The Iaboratoxy will measum; doethnent,and report the tenveratm of the sample container upon ariivat at the laboratory.
