Environmental guidance for your business in Northern Ireland & Scotland

Preventing water pollution

Water pollution can come from a number of different sources. Many solids, liquids and gaseous substances can cause pollution if they enter the water environment. Common pollutants include chemicals, oil and waste products. Even substances such as milk, which pose no risk to human health, can cause serious harm to the water environment.

You may require authorisation if you discharge anything into surface waters or groundwater. Surface waters include rivers, reservoirs and canals, and make up a small percentage of fresh water reserves. Groundwater is all water below the water table. Groundwater makes up the largest available reserve of fresh water.

This guide outlines the main causes of water pollution, and when businesses need to apply for surface water or groundwater authorisations. It also describes how to prevent pollution incidents and gives tips on how to store and handle materials responsibly.
