Selected groundwater sampling and filtering methods were evaluated to determine their effects on field parameters and trace metal concentrations in samples collected under several types of field conditions. The study focused on sampling in conventional standpipe monitoring wells under conditions where traditional approaches to sampling may produce turbid samples. However, filtration may also remove colliodal particles that are known to be mobile under certain groundwater conditions and may be important to the transport of hydrophobic organic contaminants and trace metals. Three field sites were visited: an active municipal solid waste landfill in Wisconsin, a closed solid waste landfill in Washington, and a site contaminated by industrial waste in Nevada. Three wells at the Wisconsin and Washington sites and two wells at the Nevada site were included in the evaluation.
