Disposal of drench solutions

The  Groundwater Regulations complete the implementation of the Groundwater Directive (Protection of Groundwater against pollution caused by certain dangerous substances – 80/68/EEC). Implementation of the Regulations helps prevent pollution of groundwater by controlling discharges or disposals of certain dangerous substances, including pesticides, where they are not already covered by existing legislation.

A drenching unit contains approximately 1000 litres and will treat on average 300 bins of fruit. Each bin will take out about two litres of solution, leaving about 400 litres to dispose of for each change. Disposal should be by one of the following methods:

  • Place redundant solution in a suitable container pending collection by a registered waste disposal company for transport to a licensed waste disposal facility.
  • Use suitable equipment designed to treat liquid waste containing pesticides, such as a Sentinel.
  • Disperse on an area of land that has been authorised by the Environment Agency for the purpose. Authorisations must be subject to ‘prior investigation’. Information provided by the applicant will form the basis of this ‘prior investigation’, to assess whether the activity is acceptable. In most cases it is anticipated that the information provided, together with any already held by the Agency will be sufficient to determine the application.
