Susan Willis, Senior Engineering Project Manager
"Membership in the CA-NV Section has been an incredibly important aspect of my work in drinking water. I’ve been able to meet professionals working throughout California, Nevada, and the entire US to discuss ways to improve water quality, system service, source protection, and public health. I’ve also enjoyed the opportunity to contribute to a Section publication (Distribution System Flushing) in my area of expertise. I look forward to engaging with the Section for years to come."
