About the Webinar

1. EPA's Lead Service Line Inventory Guidance

This presentation provides an overview of EPA’s Guidance for Developing and Maintaining a Service Line Inventory. The guidance was developed to assist water systems in developing and maintaining service line inventories and to provide states with needed information for oversight and reporting to EPA. The guidance provides best practices for inventory development and communicating information to the public; includes a template for water systems, states, and Tribes to use or adapt to create their own inventory; contains case studies on developing, reviewing, and communicating about inventories; and highlights the importance of prioritizing inventory development in disadvantaged communities and where children live and play.

Presenter: Kira Smith, EPA's Office of Water. Kira is an environmental engineer in EPA’s Office of Water, Office of Ground Water and Drinking Water managing implementation of the lead and copper rule. She has over 20 years of experience in the drinking water industry and previously worked for EPA on the 2007 lead & copper rule short-term revisions. In addition to EPA, she has worked for very small to very large utilities, and as an engineering consultant for various projects in and around Tampa, Florida. 

2. Corrosion Test Methods

Review of Bench Top and Pilot Lead Corrosion Assessment Studies. Bench top and pilot lead corrosion studies are gaining more interest, considering revisions and upcoming improvements to the Lead and Copper Rule. This presentation reviews studies ranging from simpler month(s)-long bench top dump-and-fill stagnant water tests to more complicated year(s)-long intermittent flow pilot studies. With increasing complexity in design and operation, studies more closely approximated real plumbing conditions at increased cost, footprint, and duration. Comparison of bench top and pilot designs (in terms of lead test piece age/dimensions/ configuration/replicates, study duration, sample collection, and other factors) can assist in the selection of a design that matches the needs and constraints of the study.

Presenter: Christina Devine, Ph.D., Oak Ridge Institute of Science and Education. Christina is an Oak Ridge Institute of Science and Education (ORISE) post-doctoral fellow at the EPA's Office of Research and Development, Center for Environmental Solutions and Emergency Response, in Cincinnati, Ohio. As a part of the Water Infrastructure Division her research is focused on lead in drinking water.
