Reference: 00/TX/02/02 ISBN: 1 84057 223 X Published Date: 17/04/2002 As part of a trial of a DTA approach in the UK a case study was study carried out on the River Esk between Langholm and Canonbie (Dumfrieshire), a location where pesticides were believed to be affecting receiving water quality. The project was designed to evaluate selected elements of a proposed DTA protocol, short- term (largely lethal) ecotoxicity tests and associated procedures for effluent control in a freshwater catchment. The results showed limited evidence of short- term (largely lethal) ecotoxicity in the Esk even though the Langholm STW final effluent showed ecotoxicity when traders were discharging. Risk assessments of the final effluent provided conclusions consistent with the receiving water data. The learning points and recommendations from the case study will be used in the development of Technical Guidance.
