However, these coastal areas can become contaminated with disease-causing bacteria that threaten public health, disrupt water recreation, and pay a toll on the Great Lakes economies that depend on summer tourism.

The U.S. Geological Survey Great Lakes Beach Health initiative provides science-based information and methods that help beach managers make more accurate beach closure and advisory decisions, preventing unnecessary beach closures while protecting public health.

However, these coastal areas can become contaminated with disease-causing bacteria that threaten public health, disrupt water recreation, and pay a toll on the Great Lakes economies that depend on summer tourism.

Similar to weather forecasts, the USGS Ohio Nowcast system uses near real-time information to estimate water-quality conditions and E. coli concentrations at specific beaches in Ohio. It uses mathematical models that are developed from several years of measurements taken at particular sites.

This assistance has helped the Bureau des Mines et de l'Energie (BME) in Port-au-Prince establish a Seismology Technical Unit and develop a first-ever national seismic network in Haiti. The Seismology Technical Unit also has an active outreach program aimed at education for local schools as well as Haitian officials, and has established itself as the authoritative local agency for matters related to earthquake hazard. A total of 15 seismic stations are now operating in Haiti, including six NetQuakes instruments owned and operated by the BME, seven USGS instruments that remain in Haiti on long-term loan, and two instruments installed by National Resources Canada. For any earthquake large enough to be felt, the NetQuakes instruments transmit triggered data via the Internet to the BME as well as several international data centers, providing a rapid-assessment capability that was lacking at the time of the 2010 earthquake.

As part of this collaboration, USGS scientists traveled to Cap Haitien, the largest city in North Haiti, in May 2013. In this photo, the technical director of the BME Seismology Technical Unit, Jean-Robert Altidor, installs one of the strong-motion instruments.
