Title: Study of ferruginous minewater impacts in Wales: phase 2a determination of remedial options: volume 1: main report
Author: National Rivers Authority Welsh Region
Document Type: Monograph
The closure of most of the Welsh coal deep mining industry has resulted in a substantial increase in the number and impact of ferruginous minewater discharges. These discharges have resulted in environmental damage to many of the rivers in the affected areas. The proliferation of these discharges, coupled with an increase in general environmental awareness, has led to public and political pressure for the problem to be solved. As a result, the National-Rivers Authority Welsh Region (NRA) have identified a series of studies aimed at evaluating the possibility of permanent and cost effective solutions, as far as is possible. The first phase of work, comprising the identification of all the ferruginous discharges in the coalfields, has been completed by the NRA. Of these, the most seriously polluting sites have been selected and ranked in terms of the degree of impact. The survey only covers discharges from abandoned coal mines. The overall objective of this phase of the work is to identify and define the possible options for remedial action for each of the selected sites. For each site, practical options will be considered and a preferred option selected. An estimate of the cost of the preferred options will be presented, together with a summary of the benefits which may be expected.
