KENNEWICK, Wash.-Peak toxic algae season is here and expected to run through early October.
The Benton-Franklin Health District has been conducting scheduled testing at drinking and recreational water sites along the Columbia River since May.
“August marks the start of the peak season for toxic blooms,” said Jim Coleman, Environmental Health Specialist with BFHD. “Extreme temperatures and low river levels create ideal conditions for harmful algal blooms.”
According to the BFHD, the latest water testing, conducted on July 22, showed no algae toxins at water treatment plant intakes, however, toxins below the threshold for recreational use were detected at Leslie Groves Swim Beach and Howard Amon Park.
Those using the river are advised to use caution from now until October, especially if clumps of green, brown or reddish scum are visible.
Dogs are especially at risk from toxic algae, according to the BFHD and should not be allowed to eat or chew clumps of algae, should not be allowed to lick their fur after going in the river and should be rinsed off after being in the river.
People and animals are exposed to toxic algae by ingesting the water and symptoms can show within 15-20 minutes.
Symptoms in animals include weakness, difficulty breathing, convulsions and death.
In people symptoms may include numbness of the lips, tingling in fingers and toes, and dizziness.
Anyone experiencing any symptoms of toxic algae ingestion should contact their doctor.
The BFHD will post updates on toxic algae blooms and water conditions online.
