Improving Water Quality
The mining industry had a catastrophic impact on the quality of the river with all the mine waters being pumped straight into the river with no treatment. For very long periods, probably more than a century, the river was continuously black with coal solids and little if anything could live in the river. This was compounded by the very basic sewage disposal arrangements which saw all the sewage discharged into the same river. Not until the 1970s was there real investment made in improving the sewage treatment arrangements.
Since the early 1970s the river has been steadily improving in quality largely due to the closure of all the coal mines and through the investment in sewerage and sewage treatment.
