Title: River Tavy EC Freshwater Fish Directive failure 1993
Author: Peter Long
Document Type: Monograph
Abstract:
Downstream of Crowndale sewage treatment works, the river Tavy is a designated salmonid site for the EC Freshwater Fish Directive. In 1993 the site failed the standard for total ammonia. There is a history of water quality problems in this area, with previous work indicating sewage and urban runoff as the major sources. A previous investigation in 1991 concluded that the Crowndale landfill site was having no impact on the water quality and that the principal cause of total ammonia failure was the effluent from Crowndale Sewage Treatment Works. This report recommended monitoring the effectiveness of planned capital work to Crowndale STW.
