Nitrogen (N) pollution of rivers and groundwater costs billions of pounds per year globally in water treatment and environmental damage from eutrophication.
Understanding two-phase flow dynamics in porous media is essential for many applications including petroleum engineering, hydrogeology, contaminant transport in groundwater, and chemical engineering industry.
Groundwater contributes over 6300 Ml/day to the overall public water supply in the UK – corresponding to around 30 % of supply (British Geological Survey, 2015).
It has been estimated there are between 5 and 50 trillion plastic particles on the surface of the ocean. Microplastics are typically defined as particles.
