What is water dredging?

Water dredging is the process of removing silt, clay and small particles of rock from the bed and sides of a waterbody. Over time silt and other sediment builds up, which reduces the capacity of the river channel.

In the UK, approximately 300,000 homes have misconnected plumbing, sending grey and foul water directly into streams and rivers instead of sewage treatment works, polluting the waterways and damaging aquatic ecosystems.

“The water industry estimates that misconnections cause a daily sewage discharge to streams and rivers equivalent to all the foul waste produced by a town the size of Swindon (or about enough to fill 16 Olympic-sized swimming pools).”

A major wastewater treatment improvement scheme in Millbrook, Southampton has reached its key phase. The scheme is a part of a £25 million project, in which the treatment works in Millbrook have been rebuilt.

Lead in Ancient Rome’s Water Was 100 Times More Than Natural Level

A scientist-led investigation in Rome has shown lead levels in water were at a considerably higher level than natural levels. The scientists believe that the high levels were around 100 times higher than what they should have been, however luckily not high enough to cause any substantial damage.

Second journal paper published from collaboration with the University of Brighton

Following a blog posted on 24.05.2012 about collaboration between Aquaread and the University of Brighton, we can now report that a second paper has been published in the Earth Surface Processes and Landforms by Dr Gary Bilotta and PhD student Magdalena Grove (https://www.brighton.ac.uk/about-us/contact-us/index.aspx).

In an earlier blog post we wrote about how Aquaread are supporting water testing in the Arctic. The research team from the University of Brighton have set off on their first water testing trip and are currently in Iceland. This video explains some of the work that they have been doing in the Litla-Skard catchment in windy Iceland:

Aquaread is supporting a research trip to the Arctic! Researchers from the University of Brighton will be travelling to Finland and Iceland to conduct water quality monitoring in the pristine rivers of the Arctic to seek to understand the contrasting water quality requirements of different freshwater ecosystems.

New research from the University of Brighton could revolutionise the way the EU legislate water quality. The research led by the University’s Dr Gary Bilotta was funded jointly by Aquaread and the Engineering and Physical Research Council.The purpose of the research was to improve the European water quality guidelines and has discovered that high levels of suspended particulate matter (SPM) are actually essential to the health of some types of freshwater ecosystems. These findings could lead to changes in the way that water quality is managed to protect aquatic wildlife.
