Our New Approach to Water Sampling Analysis

At SEPA, we are proud to announce the launch of a new method for analysing chemicals in our water systems. Using advanced liquid chromatography and high-resolution mass spectrometry, we can now screen for hundreds of chemical compounds from a single water sample. This represents a significant advancement in our environmental monitoring and protection.

Why this matters for Scotland and our environment

Scotland’s waterways are vital to biodiversity, public health, and the livelihoods of our communities. However, chemicals from sources such as agriculture, pharmaceuticals, and industrial runoff pose a growing threat. By adopting this innovative approach, we can detect a wide range of substances, including previously unknown chemicals. This allows us to identify potential risks earlier, supporting better-informed actions to protect our water environment.

Traditionally, our water analysis method required targeting specific substances, limiting the scope of detection. Now, the horizon scan technique enables us to uncover emerging threats, providing a more complete picture of Scotland’s aquatic ecosystems. From pollution events to ecosystem health assessments, this method equips us with the tools to better understand and protect our water resources.

A greener and more efficient method

Our new approach also reduces the environmental footprint of water sampling by requiring smaller sample sizes. The data collected can be revisited with future technologies, eliminating the need for repeated sampling and allowing for ongoing innovation.

Collaborating for the future

The data and insights generated will contribute to broader initiatives and inform collaborations with partners including the One Health Breakthrough Partnership and academic researchers. This collective effort will advance our understanding of chemical impacts and support the development of effective policies.

By enhancing our ability to track and understand chemical substances, we are taking a vital step toward preserving the health of our rivers, lochs, and streams for future generations.
