Picturing Algal Blooms in Local Waterways
By Marguerite Huber
For years now, I have been learning about algal blooms: from seeing and studying them first hand in a lake and watershed management course in graduate school, to watching bloom events unfold and writing all about them here at EPA.
But you don’t have to be studying algal blooms or work at the EPA to see them. Algal blooms can occur in lakes, rivers, and oceans, where there is an excess of nutrient pollution, sunlight, and slow-moving water. Nutrient pollution is one of America’s most widespread, costly, and challenging environmental problems.
This summer, the National Environmental Education Foundation teamed up with EPA and the North American Lake Management Society to bring attention to algal blooms and their association with nutrient pollution by hosting the 2014 Algal Bloom Photo Contest. Contestants used Facebook, Instagram, and #AlgalBloomPhoto14 to enter their photos of algal blooms in their local waterways. The submissions from all over the country will help build a photo library that can be used to educate others about algal blooms and their impacts. Out of hundreds of entries, three were chosen as winners.
Along with the winning image of the duck family above, here are a couple more of my favorite entries.
A green lake is not something you probably would expect to see on a stroll through Central Park.
Surrounded by sand, water—and algae!
