Swimming, boating, fishing: There’s nothing quite like making a splash to cool off during summer months.
But environmental officials are urging Virginians to take caution because many people don’t realize the dangers that could be lurking in local bodies of water or don’t take precautions to stay safe.
Algae blooms can often be a sign that a lake or pond is healthy, but excess growth can disrupt the natural ecosystem, according to information from SOLitude Lake Management.. Certain species of unchecked algae can even produce harmful toxins.
These dangerous growths are called harmful algal blooms, or HABs.
When humans or animals are exposed to HABs, they may experience “skins rashes, liver and kidney toxicity, nervous system problems, respiratory complications and even death,” the company said.
It’s especially important to be wary of HABs when visiting bodies of water in areas near agriculture or urban development.
Here are some tips from on dealing with HABs:
Accurately identify: Monitor local bodies of water for drastic increases in algal growth. Some possible indicators of HABs are parallel streaks, clumped dots and odd water surface coloration.
Dispose of organic materials: When organic debris like leaves, grass or sticks accumulate in water bodies, they decompose and create the perfect environment for HABs to flourish. Combat this buildup by raking leaves at regular intervals and always cleaning up after yard work.
Establish a buffer: Heavy rainfall can bring bring sediment, trash and debris to water bodies in the form of runoff, once again aiding the growth of HABs. Allowing deep-rooted vegetation to grow near the edge of the water can act as a barrier against this problem.
Reduce nutrients: Certain products can be added to water bodies to remove free reactive phosphorus. This works to make water clearer and cap the extra nutrients feeding excess algae.
Add beneficial bacteria: Another way to limit extra nutrients is through “biological augmentation,” where products containing beneficial nutrient-eating bacteria can be added to water bodies.
Add aeration: Products like fountains and aerators can also combat unwanted algae by circulating stagnant water.
Test water quality: Regular, preemptive testing of water quality can work to predict HABs before they become a problem. If pH or nutrient levels are irregular, take steps to stabilize the body of water before HABs begin to invade.
