"STS was invited independently by the Environment Agency and Severn Trent Water to carry out a series of monitoring operations in an area of Edgebaston which had a history of issues arising from the misconnection of waste water into a “clean” surface water sewer system"
"Of particular interest are water courses where known sources of potential pollution exist from sewage treatment works, storm drain overflows, agricultural activity such as slurry pits or illegal discharges"
"Over a 4 week period the samples consistently and distinctly showed the difference between potable and highly treated recycled waters, with fluorescence counts of around 500 for potable water and 1800 for recycled water"
