Stay Safe at the Beach
An epidemiological study by the Santa Monica Bay Restoration Commission revealed that swimming in water contaminated with urban runoff can cause illnesses such as earaches, sinus problems, diarrhea, fever and rashes. That’s because polluted storm water runoff almost always contains pathogenic microorganisms such as bacteria, viruses and protozoans.
Good Bugs vs. Bad Bugs
Microorganisms are essential to all forms of life. Billions of types of microorganisms serve as building blocks for ecosystems around the world. These helpful bugs are known as antigenic microorganisms and serve necessary functions in the food chain, such as helping humans digest food or aiding in the treatment of waste water.
The bad bugs, or pathogenic microorganisms, are the ones that cause problems and pose a public health risk, especially when they find their way into our local rivers, creeks, lakes and beaches. Fecal matter from humans, dogs and wildlife are the biggest contributors of pathogenic microorganisms in our environment.
