Penobscot Indian Nation Safeguards Tribal Waterways

Tribal members of the Penobscot Indian Nation have long believed that the Penobscot River was the lifeblood of their people, providing food and transportation needed to support survival. Clearly, keeping water quality good in the river is of concern to natural resource managers with the tribe. But the Penobscot River is not the only waterway that flows through tribal lands. There is Dolby Pond, a prominent water body in the state of Maine monitored in recent years by a sensor-equipped floating platform , and many other streams and creeks that trickle through the nation’s territories. For these, natural resource managers make routine trips to monitor their health, relying on significant parameters like temperature, conductivity, dissolved oxygen and pH.

Researchers Find Link Between Climate Change and Gastrointestinal Illnesses

An understanding of climate change’s effects on the environment has become commonplace and grows every day, but one researcher from Florida State University is looking to answer a new question: What are climate change’s effects on people’s health? In one of the first studies of its kind, Chris Uejio, an assistant professor at FSU, and a team of researchers studied how climate change can affect the roughly 20 million Americans (according to the Environmental Protection Agency) who consume untreated drinking water on a daily basis. Because climate forecasts are predicting higher rainfall rates over the next few decades, coming down in intense storms, Uejio said those flashes could cause flare-ups in waterborne illnesses.
