Short description: This project is being undertaken by the University of Newcastle upon Tyne and Northumberland County Council. Most permeable reactive barriers (PRBs) constructed to date have targeted organic contaminants in groundwaters. This project involves a relatively new application for the passive treatment of acidic, metalliferous leachates which commonly drain from perched water table systems in old mine spoils and similar bodies of contaminated land. A full-scale PRB for groundwater of this type is currently under construction at Shilbottle, Northumberland, and will be monitored (with labour and lab costs funded in the first instance by the EU's PIRAMID project) to establish precisely how the attenuation of acidity occurs in practice in full-scale PRBs, and how long such systems can be anticipated to perform before extensive renovation will be required. 
Long description: The main objectives of the project are: (a) To restore the Tyelaw Burn to something approximating 'good status', which it has not enjoyed for many decades, since the deposition of spoil began at the Shilbottle site. (b) To demonstrate PRB technology based upon bacterial sulphate reduction processes for the remediation of acidic groundwaters emanating from old spoil heaps. (c) To develop a highly-characterised PRB which can be used to address hydrodynamic and solute transport issues which are common to PRBs applied to all types of leachate. (d) To provide high-quality data for the 2003 EU PIRAMID guidelines on passive treatment system design and construction (for EU-wide use thereafter) (e) To make available a complex biogeochemical reactor which will have multiple possible educational uses for science and engineering students.
