Applicant's summary and conclusion

Executive summary:

As part of the water surveillance program according to DuPont Asturias IPPC permit, levels of the test substance were measured in effluent from the waste water treatment plant at the Asturias S.L. site and in water, sediment, and biota from the Aviles estuary over a three year period from 2007 to 2009. No detectable levels were identified in any of the samples from all locations.
