As the people of Flint, Michigan, continue to suffer from the effects of a lead-contaminated water crisis, more and more celebrities are beginning to step up: Diddy and Mark Wahlberg have pledged to donate 1 million water bottles to Flint via AQUAhydrate, a Los Angeles–based bottled-water company they both partially own. The company plans to send 5,000 cases of water to the city by Wednesday, and says it will continue to send more as needed. Eminem and Wiz Khalifa have also contributed to the company’s pledge. AQUAhydrate’s sizable efforts follow notable donations from Cher, as well as Pearl Jam, Jack White, Meek Mill, and Big Sean. Flint, meanwhile, remains under a federal state of emergency declared by President Obama.
