Water Quality Equipment: Calibration, Maintenance & Use
Instrument Preparation:
You will use a dissolved oxygen meter, a pH meter, a conductivity meter, and a thermometer. Additional water quality parameters may be collected in the future using different instruments and sampling procedures and you will receive training as needed. However, at this point you should be familiarized with the three meters we currently use with this program. This course provides volunteers with detailed procedures for instrument calibration, maintenance, and use.

Safety
Safety must be the primary consideration in deciding if, when, where, and how to take a measurement or collect a sample. This course will give the volunteer some important safety considerations when collecting data in the field.

Water Quality Parameters
Volunteers will collect data on the four basic water quality field parameters: Dissolved Oxygen, pH, Conductivity, and Temperature. However, this course will give the volunteer a working knowledge of the physical and chemical properties that can affect the water quality of lakes, rivers, and streams. Many of the additional parameters discussed in this course would require different sampling protocol than for the four field parameters, but volunteers should have an understanding of all of these parameters and how they can affect eachother.

Quality Assurance & Quality Control
Quality control refers to the devising and implementing of safeguards to minimize the variability of monitoring results. This course illustrates the importance of accuracy and precision as they relate to water quality sampling and the difference between the two.
