Golden State Water Company (GSWC), which serves more than one million customers across California, has implemented AMS’s MetalGuard™ online analyser to strengthen its compliance and operational efficiency in managing selenium levels in groundwater.
The utility faced challenges with fluctuating selenium concentrations that periodically exceeded the Maximum Contaminant Level (MCL). By integrating continuous, real-time monitoring, GSWC now has immediate visibility into water quality conditions, allowing operators to make timely adjustments to treatment processes without waiting for delayed laboratory results.
The MetalGuard analyser provides real-time data that enables operational flexibility between ion exchange and blending methods based on current water conditions. This proactive approach improves efficiency, reduces waste disposal costs, and enhances cost control while ensuring compliance with regulatory standards for safe drinking water.
GSWC’s experience demonstrates how real-time analytics can empower utilities to maintain regulatory compliance and optimise treatment performance while managing variable heavy metal concentrations.
