Groundwater Classification - Trend Assessment and Points for Trend Reversal - 2009

Date published: 01 September 2009

This paper describes the method for assessing upward trends in concentrations of pollutants and natural parameters in groundwater. It also sets out how we determine starting points for trend reversal. The identification and characterisation of trends is a requirement of the Water Framework Directive (WFD) and the Groundwater Daughter Directive (GWD) and forms part of the groundwater body chemical status assessment.
