Before proceeding to the monitoring site and collecting samples, volunteers should review the topics addressed in Chapter 7 . Once at the monitoring site, volunteers should record general site observations, as discussed in Chapter 7 . If samples will be collected in the field for later measurement, follow these collection and storage steps. See Chapter 7 for information on cleaning and preparing bottles. Use 200 ml glass or polyethylene bottles.
Some procedures require smaller samples.
Label the bottle with site name, date, time, data collector, and analysis to be performed. Wearing latex gloves, plunge the bottle into the water. Fill the bottle completely and cap tightly. The following section describes various methods to analyze a water sample for salinity. If using a salinity kit based on testing chloride ions, follow the directions that come with the kit.
