Let’s Begin…

The water crisis in Flint, Michigan is a prime example of science being ignored, unknown and even misused. The switch in water source damaged hundreds of millions of dollars of infrastructure, caused deadly bacterial outbreaks and exposed children to lead poisoning. SciShow explains the chemistry behind how so many things went wrong.

Lead seepage into the drinking water in Flint, Mich., has caused a massive public health crisis. The problem began when the city switched its water supply in 2014. Almost immediately, residents of Flint — a majority-black city where 40 percent of people live in poverty — started complaining about the quality of the water. City and state officials denied for months that there was a serious problem. Later studies would reveal that the contaminated water was also contributing to a doubling—and in some cases, tripling—of the incidence of elevated blood lead levels in the city’s children, imperiling the health of its youngest generation.

When is water safe to drink?
Water is refreshing, hydrating, and invaluable to your survival. But clean water remains a precious and often scarce commodity – there are nearly 800 million people who still don’t have regular access to it. Why is that? And how can you tell whether the water you have access to — whether from a tap or otherwise — is drinkable? Mia Nacamulli examines water contamination and treatment.

Where we get our fresh water
Fresh water accounts for only 2.5% of Earth's water, yet it is vital for human civilization. What are our sources of fresh water? In the first of a two part series on fresh water, Christiana Z. Peppard breaks the numbers down and discusses who is using it and to what ends.

Are we running out of clean water?
Despite water covering 71% of the planet’s surface, more than half the world’s population endures extreme water scarcity for at least one month a year. Current estimates predict that by 2040, up to 20 more countries could be experiencing water shortages. These statistics raise a startling question: is the Earth running out of clean water? Balsher Singh Sidhu takes a closer look at water consumption.

Science in service to the public good - Siddhartha Roy
We give scientists and engineers great technical training, but we're not as good at teaching ethical decision-making or building character. Take, for example, the environmental crisis that recently unfolded in Flint, Michigan -- and the professionals there who did nothing to fix it. Siddhartha Roy helped prove that Flint's water was contaminated, and he tells a story of science in service to the public good, calling on the next generation of scientists and engineers to dedicate their work to protecting people and the planet.
