Surface water includes rivers, streams and ditches, as well as rainwater running off roads, roofs and fields. Clean water is essential for healthy rivers, thriving wildlife and safe places to swim and enjoy nature. Pollution threatens these benefits and can increase the cost of treating drinking water.
In the Adur and Ouse catchment, pollution comes from sources including agriculture, sewage discharges, septic tanks and urban runoff. Steep slopes and heavy clay soils can increase the movement of pollutants into our waterways. Key concerns include nitrates, phosphates, harmful bacteria, pesticides and sediment. Chemicals from everyday products, microplastics and litter are also emerging concerns.
Protecting water quality means reducing pollution at source and restoring the natural features that help filter runoff and keep our rivers healthy.
