High Quality Groundwater Sampling This document provides sampling guidelines primarily for ground water monitoring wells that have a screen or open interval with a length of ten feet or less and which can accept a sampling device. procedures that minimize disturbance to the aquifer will yield the most representative ground water samples. this document provides a summary of. New nfm publication: chapter a6.4 ph. the national field manual for the collection of water quality data (nfm) provides documented methods and protocols for usgs field personnel who collect water quality data. the nfm provides detailed, comprehensive, and citable procedures for sampling water resources, processing samples for analysis of water.
