Accreditation: 2 California Drinking Water Contact Hours awarded  Description: Chromium in drinking water has been regulated since 1977, but hexavalent chromium, more commonly known as chromium-6, has had a turbulent regulatory history. In 2014 chromium-6, due to its increased carcinogenicity, had its own maximum contaminant level (MCL) established in California. In 2017, that MCL was invalidated. Now a new MCL has been proposed. Chromium-6 occurs naturally in Californian rock formations and is an industrial contaminant. In 2017, it was found in almost 4,000 wells. This workshop will help systems prepare for the new MCL and make informed decisions on treatment techniques. Participants will learn: Basic information regarding chromium and its ionic forms The adverse health effects caused by chromium-6 exposure The regulatory history of chromium What to expect from regulations in the future Treatment techniques Practical considerations when choosing treatment techniques The recommended audience includes operators, managers and board members that have an interest in providing chromium-safe water to their customers.

Accreditation: 2 California Drinking Water Contact Hours awarded Description: How is your well performing? How do you know what is going on deep in the ground? Like all equipment, water wells must be maintained to ensure long life and quality water within the system. Wells need to be monitored regularly to compile vital information on the health of the source. Participants will learn: Well inspection Well operation and maintenance practices Well pump basics and how to properly throttle a well pump Groundwater quality concerns and trouble indicators Measuring drawdown and tracking over time Well sounders: Which one is right for me? The recommended audience includes operators, management, water system personnel or anyone with an interest in better understanding the value of operating a safe drinking water system.
