EPA's Office of Research and Development and Office of Water as part of their Small Systems Research Webinar Series presents a free webinar on Lead Service Lines. The first part of the webinar will offers a qualitative comparison of method cost, accuracy, disturbance, and other impacts to lead service lines, as well as an example stepwise approach to identify unknown service line materials.The second part provides an overview of the Drinking Water State Revolving Fund, explains DWSRF eligibilities related to lead service lines, and discusses opportunities for lead service replacement under the Bipartisan Infrastructure Law. Who should attend: State primacy agencies, Tribes, community planners, technical assistance providers, academia, and water systems interested in issues facing community water systems and solutions to help solve them. Register Here. A certificate of attendance will be offered for this webinar.

This webinar is designed to improve understanding of key concepts and mathematical relationships in chlorine disinfection. Attendees will engage in calculating chlorine dosages and feed rates for the three forms of chlorine in order to ensure necessary disinfection is taking place in drinking water. Also, attendees will learn how to calculate CT values in order to comply with activation requirements for viruses and Giardia.  Presenter: Gregory Pearson, Water and Wastewater Trainer, Great Lakes Environmental Infrastructure Center at Michigan Technological University Who should attend: This workshop is designed for water systems serving 10,000 people or fewer (though systems of any size may attend), especially targeting local government systems. Owners of privately owned systems, consultants, and technical assistance providers serving water systems are also invited to attend.  Register Here

Tuesday, May 17, 2022 Time: 1:00 pm - 2:00 pm EDT  Description: This webinar is designed to improve understanding of key concepts and mathematical relationships in chlorine disinfection. Attendees will engage in calculating chlorine dosages and feed rates for the three forms of chlorine in order to ensure necessary disinfection is taking place in drinking water. Also, attendees will learn how to calculate CT values in order to comply with inactivation requirements for viruses and Giardia.  Learning Objectives:  Calculate dosage, demand, & residual for chlorine disinfection applications.  Differentiate between combined, total, and free chlorine residuals.  Calculate feed rates for gas, liquid, and solid chlorine forms. Calculate the effective volume of basins and pipes and determine contact time credit.  Calculate CT values for a disinfection application. Evaluate compliance by comparing CT values to log inactivation tables.  Presenter: Gregory Pearson, Water and Wastewater Trainer, Great Lakes Environmental Infrastructure Center at Michigan Technological University   Who Should Attend:  This workshop is designed for water systems serving 10,000 people or fewer (though systems of any size may attend), especially targeting local government systems. Owners of privately owned systems, consultants and technical assistance providers serving water systems are also invited to attend.
