Help East Chicago Get Clean Water

July 10, 2017.

Please participate in our effort to make sure the people of East Chicago have access to clean drinking water. The EPA estimates up to 90% of the households there are at risk of lead exposure from their drinking water pipes. Residents are doing their part to address this and other environmental injustices in their community. Let’s show our support by helping to ensure that until this crisis is fully addressed, they have access to clean, drinkable water. Find out how you can help here.

Join Us in Protecting Indiana's Waters

River with trees

July 7, 2017.

Water quality is fundamental for streams and rivers to thrive and support biological and human wellbeing. Communities in Indiana, such as Indianapolis, Columbus and Bloomington, continually face a variety of threats to clean water. Impaired water quality endangers human and environmental health, as well as jeopardizing long-term economic prosperity. The task of improving water quality in Indiana requires continued support for public agencies, as well as sustained commitment from actively involved citizens. Increasing individual and community commitment to attain water quality restoration requires acting collectively to create a locally specific plan that works to solve the challenges each area is confronting. Become an engaged citizen by learning about action items you can take within your community to build a better future for all Hoosiers.

Sierra Club Hoosier Chapter's Nature Play Day at Beanblossom Bottoms Nature Preserve.

June 14, 2017.

The Sierra Club Hoosier Chapter hosted a Nature Play Day, in the form of a family hike, on June 10 at The Beanblossom Bottoms Nature Preserve, in Ellettsville, Indiana. We had 12 children and 10 adults participate. The weather was on our side, and the trail was resplendent with colors and wildlife in the sun. The trees provided some welcome shade, and we were lucky enough to see a fawn up close, as well as frogs, dragonflies, butterflies, a woodpecker and several other birds. This was our first dedicated family hike and we hope there will be many more!
