The environmental health workforce is vital to protecting the health and safety of the public. The days when our profession could merely focus on food, water, and waste are long gone. Natural disasters such as hurricanes, wildfires, earthquakes, and floods present countless environmental hazards that often persist long after the event has ended. New and emerging vectorborne diseases such as Zika and chikungunya demonstrate that we need a clear understanding of the latest science and technology to supplement the things we learned in college. This month's column highlights the importance of credentialing and education. It also discusses the recent Environmental Health Workforce Act bill that was introduced into the U.S. Congress earlier this year. Readers are encouraged to contact their elected officials to support this bill and to let them know how critical the environmental health workforce is to our nation's health, safety, and security.
