"PTC" samples are groundwater samples collected from multi-level piezometers

"PTZ" samples are groundwater samples collected from individual piezometers

"PTB" samples are groundwater samples collected from in-mat passive diffusion samplers

"PTN" samples are groundwater samples collected from below-mat mini sand-pack screens
