December 6, 2007Report on
Blue-Green Algae Released
The Department of Environment and Conservation issued
a public advisory in September about the presence of blue-green algae in
four local ponds: Three Island Pond, Paddy�s Pond, Cochrane Pond and
Three Arm Pond. The final results from the water sample analysis
conducted on these ponds are now available to the public.
"The occurrence of blue-green algae in area ponds was
a new issue for the department," said the Honourable Charlene Johnson,
Minister of Environment and Conservation. "However, based on our
experience this summer, we have committed to purchasing field test kits
and algae sensors that will help ensure reported or suspected cases of
blue-green algae are detected and tested in a timely manner."
Prior to this summer, the department had not received
any reported occurrences of blue-green algae blooms in the province.
Blue-green algae blooms rely on elevated nutrient
levels and sunlight to grow. Increases in any or all of these factors
could lead to an algae bloom. Algae blooms typically occur late in
summer when water temperatures are higher.
"While the test results indicated the presence of
blue-green algae, we were unable to confirm a specific cause," said
Minister Johnson. "It is likely that adequate nutrient levels in the
ponds, together with persistent sunny conditions and warm temperatures
in September, led to the prolonged bloom."
The minister added that the department will continue
to monitor and respond to reports of blue-green algae blooms on a
case-by-case basis.
The detailed report and water testing results are
available on the Provincial Government Web site at
