IDDE: Partnerships and Programs for a Successful Countywide Program
Managing an IDDE program that covers 950 square miles of urbanized Southern California landscape with a population of more than 3 million people is a challenge, especially when you have a network of 400 miles of regional flood control channel and 42 miles of coastline to protect. The Orange County Public Works (OCPW) IDDE team relies on teamwork and partnerships with local, state, and federal agencies to help prevent, detect, track, and respond to illicit discharges in Orange County, CA. This talk will cover how training and coordination on a regional scale helps minimize environmental impact when larger spills and releases occur. Attendees will learn how the sharing of data and information, and the use of technology, assist with the prevention, detection, and response to illicit discharges.

Elizabeth Fassman-Beck, Engineering Department Head, Southern California Coastal Water Research Project
Automated Detection of Transient Illicit Discharges Using IoT Sensors
Orange County (California) Public Works (OCPW) is partnering with the Southern California Coastal Water Research Project, the University of Guelph and the BoSL Lab to pioneer development of an automated method for real-time illicit discharge detection. The pilot program deploys a network of internet-of-things (IoT) sensors to continuously monitor storm drains to establish, then identify deviations from, a baseline trend. If an anomaly is detected, an email/text alert calls the IDDE team to the offending site in near real-time for source investigation and mitigation. This presentation provides information on the technical hurdles, logistical planning, and proof-of-concept results of this pilot test to help improve the efficacy of IDDE programs required by NPDES permits nationwide.

This presentation will provide a road map of steps to take before deciding on a specific course of action and technology to be employed for PFAS management. We will explore the various commercialized technologies, and their pros and cons. We will then delve deeper into the various media that may be employed for PFAS management, the relative media costs under different conditions, and disposal options. This will allow a stakeholder to build a PFAS treatment system effectively, economically, and most of all safely, while remaining compliant with these new regulations.
