Options overview

Regulatory instruments drive the reduction in nitrate levels in water bodies in Europe. A number of options can be considered for reducing nitrate loadings to water. These range from land use management changes to high technology treatment processes. To find out more about the available options, click here.

PRB technology

A permeable reactive barrier (PRB) involves the placement of reactive material below the ground through which groundwater flows and reacts with contaminants (such as nitrate) or changes them to less harmful ones. The technology has been used for over a decade to treat contaminants from industrial sites, and has been tested for nitrate treatment on a number of sites around the world.
