ABSTRACT
Automatic samplers are commonly employed in the flow or time-weighted composite sampling of wastewater and stormwater samples to augment grab samples for generating representative, composite samples of a flow stream of interest. The point of sampling should be the same as described in the section of grab samples. As with surface water sampling, the goal of sampling groundwater monitoring wells is to obtain samples that are truly representative of the aquifer or groundwater in question. Anaerobic water can be oxygenated through improper sampling and handling techniques, for example, giving rise to redox reactions at the surface that are not representative of the chemistry and water quality existing in the aquifer. The laboratory being used for sample analysis will provide the approved analytical portion of the sample's processing. The common measurement devices include: 8.6 Information on the properties of solid wastes is important in evaluating alternative equipment needs, systems, and management programs and plans.
