RCAC - Operator Math 101: The Basics
2026-07-01 10:00 - 12:00 | Webinar Only
At a minimum, every public water system regardless of size and complexity requires a certified water distribution operator. In addition, those systems using treatment also must have an operator that holds a water treatment operator certification. The most significant hurdle for many grade 1 and grade 2 operators in passing the operator certification exam, however, is the math portion of the test. Typically, the math section of the certification exam constitutes about 35% of the total exam score so proficiency in math is necessary to pass the test.
The math included in the Operator 101, 102, 201 and 202 sessions are based on the expected-range-of-knowledge for the California distribution D1/D2 exams. Operator Math 301 and 302 are targeted to the grade 3/4 level exams.
The target learner for these trainings wants (and needs) one specific thing: the ability to accurately calculate operator certification exam math questions. Accordingly, these learning trainings designs focus solely on this need. These trainings are not designed for “contact hours “or participant “entertainment”. These are hands-on trainings with an expectation of continuous participation working and answering math problems throughout the entire session.
In the Operator 101 session participants will learn:

Water units (ft3 to gal, gal to wt.)
Distance (in to ft, ft to m, ft to mi)
Areas (ac to ft2, in2 to ft2, yd2 to ft2)
Volumes (ft3 to gal, gal to L, L to mL)

The EPA 2026 Virtual National Cyber Drill
2026-07-08 10:00 - 12:00 | Webinar Only
Join the U.S. Environmental Protection Agency (EPA) for the 2026 National Cybersecurity Drill. This year’s exercise will challenge drinking water and wastewater utilities to operate and maintain critical functions in an environment where telecommunications and internet access are unavailable or unreliable.
The exercise is built around a simulated scenario in which cyber and/or physical incidents degrade or disable commercial telecommunications infrastructure, internet service providers, and associated systems. As a result, participating organizations must operate in a “disconnected” environment with limited or no access to Supervisory Control and Data Acquisition (SCADA) remote connectivity, cloud-based services, email, Voice over IP (VoIP), and other digital communication tools. This exercise is designed to strengthen sector-wide resilience by testing operations under progressively degraded conditions. It enables participants to identify barriers and dependencies while reinforcing continuity of safe and reliable water and wastewater services in the absence of telecommunications and internet connectivity.
Continuing Education Units (CEUs) will be provided in most states.
Intended audience: Drinking water and wastewater utility managers and operators; IT and OT staff; emergency response planners; and state and local partners.
