Instructions:
Some of the water sampling tests are required while others
are optional. The reason for this is to provide students with enough
information to make a general determination of their water quality.
Please note that background information and test procedure instructions are described
in the
Water Sampling Tests Fieldbook.
- Review the REQUIRED and select the OPTIONAL water sampling tests from the
Water Sampling Tests Fieldbook that you would like to conduct
for this project.
- Required Tests: General Observations,
Temperature, pH, Dissolved Oxygen, & Macroinvertebrates
- Optional Tests: Nitrates, Phosphates,
Biological Oxygen Demand, Turbidity, & Coliform Bacteria
- Obtain the necessary
equipment and testing kits corresponding to the water sampling tests that you will
conduct. Make sure that you are comfortable with the testing kits
prior to the first "sampling experience". The better the comfort level,
usually, the more accurate the results.
- Once you have selected the tests, plan your trip to the fresh
water body (i.e. river, stream, etc.) and complete the water sampling
tests.
IMPORTANT: many of the water sampling tests MUST be conducted
at the fresh water sampling site. If it is not possible to conduct
a field trip with all of the students, complete the necessary tests
at the fresh water body and bring extra water samples as well as the
macroinvertebrates back to the classroom so students can have
first-hand experience using the testing equipment.
- Once you have completed the water sampling tests, proceed to the
next activity (Activity 4) to analyze your findings and make a general determination
about the water quality of the fresh water body.
