Addressing Arsenic Contamination: Ensuring Safe Drinking Water and Enhancing Laboratory Testing

Arsenic (As) is a naturally occurring trace element typically found in soil and bedrock. Tasteless and odourless, its presence in groundwater at elevated levels is believed to put up to 220 million people at risk. However, in many regions most reliant on groundwater, water testing laboratories are under-funded and under-resourced,
In this policy brief document, learn about the main analytical techniques available to monitor and measure arsenic. The role of metrology in securing a safe, clean water supply is discussed, and some specific suggestions for policymakers are made.
