Descriptions and procedures are given for several methods of sampling for which a variety of samplers may be used. Sample processing devices such as sample churns and filtration apparatus are discussed along with methods of cleaning. Analyses for unstable constituents or properties are by necessity performed in the field. This manual addresses analytical techniques and quality assurance for: (1) Water temperature; (2) specific conductance; (3) pH; (4) alkalinity; (5) dissolved oxygen; and (6) bacteria.water qualitywater temperaturewater sampleswater samplingbacteriadissolved oxygen (DO)thermal conductivityBook
