Description: Since the arsenic maximum contaminant level was lowered from 50 ppb to 10 ppb in 2001, water systems have been scrambling to comply with this more stringent standard. For many small water systems, compliance with the Arsenic Rule has been a significant technological, financial and operational challenge. This online learning event is intended to provide a small water system with a “road-map” to Arsenic Rule compliance. We will begin with review of the requirements of the Arsenic Rule. We will then explore non-treatment options for compliance, which are almost always less costly than treatment. We will then assess the pros and cons of several of the most common arsenic treatment technologies. Participants will learn: The health effects of arsenic in water Non-treatment options for Arsenic Rule compliance An overview of the most used arsenic treatment technologies Practical considerations when choosing an arsenic treatment system Who should attend: operators, managers and board members that have an interest in providing arsenic-safe water to their customers Accreditation: 2 California Drinking Water Contact Hours awarded. Contact hours have been approved for the Registered Environmental Health Specialist Program. 

Description: Worldwide, Nitrates are the most common chemical contaminant in groundwater aquifers. In 1980, nine drinking water wells in California had unsafe levels of Nitrates. By 2007, this acute contamination had spread to more than 648 wells. Nitrates continue to impact the health of California residents and the problem is only getting worse. This workshop will help you make informed decisions about mitigating this contaminant. Participants will learn: What Nitrates are How Nitrates get into drinking water The acute health effects of Nitrate exposure How to achieve compliance with Safe Drinking Water Act requirements for Nitrates An overview of the most used Nitrate treatment technologies Practical considerations when choosing an Nitrate treatment system Who should attend: operators, managers and board members that have an interest in providing nitrate-safe water to their customers.
