Nitrate concentrations
Status and trends
Where is the nitrate coming from? Agricultural fertiliser Small sewage discharges
Measures Awareness raising campaign targeted at small sewage discharge owners Catchment Sensitive Farming Initiative NVZ action programme Soil Analysis (SMN) Soil Mapping and Direct measurement of N Safeguard Zone designation Drilling additional monitoring boreholes Improved conceptual understanding
Justification for applying Art 4(4) Local hydrogeologists have developed a detailed conceptual understanding of the gwb Local hydrogeologists assess a) time lag in unsaturated and saturated zones and b) if measures are sufficiently robust to deliver good status in the long term ‘Natural conditions’ exemption used to extend the timescale for achieving good status Good status will be achieved by 2040
Lessons learnt Start by developing a strong conceptual understanding Before using the Art 4(4) exemption local hydrogeolgists must be confident that the measures will be robust enough to deliver good status in the long-term
