| Zusammenfassung |
| Land application of agricultural pesticide products may have the ability to travel to
groundwater and it has been suggested that physical properties at the site of application
controls their movement ...(Worrall et al, 2002). As of yet no one has tried to correlate
pesticide occurrence in groundwater with physical attributes of the Zones of Contribution
(ZOC) which have been specifically identified as contributing to the sampling point. The aim
of this study was to explore association between ZOC physical characteristics and pesticide
presence or absence at 158 sites in Ireland sampled for pesticides in 2008 as part
of the Environmental Protection Agency’s (EPA) national groundwater quality
monitoring programme for the European Union (EU) Water Framework Directive
(2000/60/EC).
Pesticide detections greater than or equal to the EU drinking water standard (0.1μg/L),
greater than the analysis detection limit (0.02μg/L) and those monitoring points with no
detections were identified from the 2008 groundwater quality dataset (n=158), generating a
new dataset of the 3 classes (19 sites -¥0.1μg/L, 64 sites >0.02μg/L & |
