Water Quality

Basic and advanced equipment for water quality testing in geoscience labs

Some notes on water quality studies

If you are planning to monitor a particular water body over the course of a semester or for many years, keep in mind that for some parameters, such as temperature, dissolved oxygen or pH, it's very important to test consistently at the same time of day (many long-term studies prefer samples to be taken within an hour or two of solar noon). It may also be interested to see how these parameters change in the course of a day. Field equipment may be sufficient for some tests, or it may be more appropriate to have students collect water samples in the field and bring it back to the lab for testing.

For more information on water-quality testing equipment and methods, visit the The Great North American Secchi Dip-In and the GLOBE 2003 Hydrology Chapter (more info) . The Utah Stream Team has some suggestions about making your own monitoring equipment.
