For Living Waters for the World, the mission is clean drinking water
In Tabasco, Mexico, water is left undrinkable by mineral deposits in soil and a coastal aquifer that runs beneath the Yucatan Peninsula. Many communities can’t treat it and depend on trucks to bring in drinking water. 
 
But for one small community there, a mission group helped reduce its dependence on outside water by setting up and donating a custom water filtration system. A church houses the system and gives treated water to those who can’t afford it at no cost. The water is otherwise sold commercially at half the price offered by other bottlers. 
 
Living Waters for the World is a mission project of the Presbyterian Church - USA and is no stranger to water treatment projects.

Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. 
 
For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. 
 
Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.

Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout. 
 
 As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. 
 
 One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.
