1.8.2 – Current and future challenges for achieving and maintaining good chemical status in EU water bodies following pesticide use. R.J. Blake, Compliance Services International (CSI), UK
- Robin Blake – Senior Consultant
Water represents the biggest limiting factor in our ability to feed a growing population, with agriculture accounting for 70% of freshwater use globally. By 2030, estimates suggest that our water needs will exceed current supplies by 40%. Agriculture is a key user of freshwater; however, point and diffuse pollution from pesticides and fertilizers can have a detrimental impact on aquatic ecosystems, and thus it is critical that agricultural chemicals are used effectively to ensure that food security demands are met whilst being protective of this increasingly finite resource.
In the EU, water quality management is legislated under the Water Framework Directive (WFD) which sets objectives for Member States to achieve to protect surface water and groundwater bodies. Whilst ambitious deadlines have been implemented, in 2018, only 38% of EU surface water bodies and 78% of EU groundwater bodies, were rated as having a good chemical status or higher, and therefore compliant with the quality standards established for chemical substances including pesticides.
There are both human health and environmental concerns over the impact of pesticides such as metaldehyde and glyphosate found in drinking water sources at levels above the parametric limit of 0.1 μg/L, and as such there is increasing regulatory pressure for these substances to be phased out. However, given the significant investment and length of time that it takes for new pesticides to reach the market, together with a lack of suitable alternatives in many cases, options to retain existing products on the market whilst ensuring compliance with water quality standards may allow their continued use.
This presentation will discuss current challenges with respect to achieving good chemical status in EU water bodies from pesticide use. Solutions to improve chemical status such as targeted spraying, drone and satellite technology, and a reduction in rate and frequency of pesticide applications will be explored, together with options to consider individual pesticide drinking water limits on a local, case by case basis. Finally, future challenges for the crop protection industry in designing new molecules that are protective of water quality will be highlighted.
