Sluggish water circulation can keep the nutrients from dispersing into lower concentrations, allowing the algae to multiply rapidly. Most algae species are harmless, however, some species may produce irritating compounds or toxins. They are also evaluating the cost to conduct sediment tests and DNA testing on the nutrients, and he explained that early spring is the ideal time to get control point results. In general, advisories will be lifted following two consecutive test results with acceptable levels for algal cell counts and toxin concentrations. But when too many nutrients collect and pool in a certain location, a critical threshold is reached, and algae expand quickly and dramatically.
