Obama The Big Picture: Of Infrastructure and Laws http://www.infrastructurereportcard.org/drinking-water/ Closing Comments for the Technical Community • Flint was a “miracle” – It was exposed by residents, outsiders and journalists – a complete failure of government agencies!! • Are there more Flints? • Inadequate Policies (e.g. Lead and Copper Rule) – Often, NOT completely science-based. Stay apolitical, true to your science, but also understand the politics. • A Culture of Compliance – Obsession with meeting regulations and targets than protecting public health and the environment • Water Infrastructure Challenges • Science Communication and Listening to the Public before preaching • The Public as Equal Partners and our Ultimate Client Why You and I should care Grateful acknowledgement • National Science Foundation, RAPID Grant #1556258 • Citizens of Flint • Michigan State Health Department // Genesee County Health • WaterYouFightingFor?
