On a hot day, nothing beats a refreshing dip in a pool or lake. The community pool can be a great place to hang out with friends or swim a few laps. The beach is another fun place to enjoy the sunshine, catch some waves, and cool off. These places are popular summer hangouts where you can grab some fun and relaxation. However, they are also spots where danger can lurk. Before heading to your favorite watering hole, check out this list of signs that a body of water may not be the safest or most sanitary place to swim.
If you pull up to your favorite beach and spot the tinge of green algae, stay out of the water. Blue-green algae can form an algal bloom on the upper surface of lakes, rivers, and even the ocean. An algal bloom is more common during the warm summer months or early in the fall. According to the CDC, harmful algal blooms can give off toxins that are poisonous to humans. While green is the color most commonly associated with an algal bloom, it can appear in a variety of colors and may give off a bad odor.

Avoid swimming in water that is located near animal pastures or farmland. As water runs off from the pastures, it can carry farmyard fecal matter and bacteria into the water. One danger of swimming in water that has been contaminated by fecal matter is exposure to E. coli. Gastroenteritis refers to a bacterial inflammation of the stomach and intestines. According to Purdue University, gastroenteritis is the illness most commonly linked to swimming in waters polluted with fecal matter. Similarly, chemicals used to fertilize the fields may be carried into the water through runoff or by seeping into the ground.
