There has been considerable progress in developing treatment systems for point sources of minewater pollution in recent years; however, there remains a knowledge gap in the characterisation and remediation of diffuse minewater sources. Data are prese... Read More about Quantifying the importance of diffuse minewater pollution in a historically heavily coal mined catchment.

Multi-day rainfall events appear to be an important cause of recent flooding in the UK. Hydrological data from an extensive, nested hydrometric network in the unregulated, predominantly rural Upper Eden catchment in northern England are presented for...

Buffering of alkaline steel slag leachate across a natural wetland (2006)
Journal Article

Buffering of high-pH ( > 12) steel slag leachate is documented across a small, natural calcareous wetland. The alkaline leachate is supersaturated with respect to calcite upstream of the wetland (SI calcite values +2.3) and becomes less saturated wi...

The impact of pumped water from a de-watered Magnesian limestone quarry on an adjacent wetland: Thrislington, County Durham, UK (2005)
Journal Article

Although quarrying is often cited as a potential threat to wetland systems, there is a lack of relevant, quantitative case studies in the literature. The impact of pumped groundwater discharged from a quarry into a wetland area was assessed relative...

Trace and rare earth element dispersal downstream of the Ajka red mud spill, Hungary
Presentation / Conference
Jarvis, A., Burke, I., Gruiz, K., Walton, M., & Mayes, W. Trace and rare earth element dispersal downstream of the Ajka red mud spill, Hungary

Between 600,000—700,000m³ of caustic (pH>13) red mud suspension were released from the Ajkai Timfoldgyar Zrt alumina plant on the 4th October 2010. This study highlights the dispersal of key red mudderived contaminants in downstream fluvial sediments...

Mine water outbreak and stability risks : examples and challenges from England and Wales
Book Chapter
Mayes, W., & Jarvis, A. P. Mine water outbreak and stability risks : examples and challenges from England and Wales.

Abstract Although their frequency of occurrence is rare, the sudden outbreak of mine water from abandoned mines, or collapse of waste rock stores can be environmentally significant and represent significant postclosure legacies. This paper reports on... Read More about Mine water outbreak and stability risks : examples and challenges from England and Wales.
