Title: Wheal Jane Minewater Project consultancy studies 1996-1999 : appraisal and selection of long term treatment option, version 5
Author: Environment Agency South West Region
Document Type: Monograph
The Wheal Jane Minewater Project was initiated following the uncontrolled release of acidic metal laden minewater from the Wheal Jane mine, near Truro, Cornwall. The release, in January 1992, caused widespread discolouration in the Camon River, Restronguet Creek, Carrick Roads, the Fal Estuary and beyond. Previous studies had determined the major influences on the minewater regime to be Wheal Jane mine and County Adit and had made preliminary recommendations regarding a long-term treatment strategy. The report also recommended that the Existing Treatment Plant (ETP) continue to operate until a long-term treatment option had been determined. The ETP, which has operated since 1992 and enables a water quality of No Deterioration to be maintained in the Camon River, uses simple lime dosing to neutralise the minewater acidity and precipitate the heavy metals, which are then settled and deposited into the adjacent CVTD. The ETP was shown to be the lowest cost method of minewater treatment whilst the dam is available, this remains the case.
