Published 04/08/2023   |   Reading Time minutes

Water is an essential resource. Whilst our natural waters form important ecosystems and are integral to the environment, water also plays critical roles in applications as diverse as sanitation, industry, navigation and recreation.

Water quality is therefore crucial to health, the economy, environment, and our ability to enjoy the natural world. Whilst water quality is often discussed in terms of how polluted a water resource is, it can also refer to any chemical, physical, and biological properties affecting its use.

Our new research briefing provides an overview of water quality in Wales. It outlines how water quality standards are implemented, monitored and upheld, and who’s responsible. It also discusses some of the main challenges to water quality in Wales, and what the Welsh Government has been doing to tackle them.
