A.2 Study of Floating Algae and Bacteria
The record of water quality at the Cook Plant, particularly as it is
expressed by the numbers and types of planktonic algae, is of prime importance
to the ultimate assessment of whether the plant's waste heat has produced
change in the local aquatic environment.
The planktonic algae live directly with and from the physical and chemical
conditions of the aquatic environment. Being alive and irritable (sensing and
responding to environmental change) they are apt to be that delicate and sensitive indicator of environmental change wherein the effects of the plant's
waste heat should be watched for.
Unfortunately, the record contained in the planktonic algae is cumbersome
to establish and difficult to work with. A customary and proper means of
approach to whether changes in the aquatic environment have occurred is to
establish, and watch for variations from, the annual cycles exhibited by these
microscopic plants. Plankton algae parameters that are commonly watched are:
1. Variations in total numbers from year to year and from season to
season within each year.
2. Variations in season to season dominant species, and comparisons of
abundance of these dominants from year to year.
