Journal Article
Hamidi, M. D., Gröcke, D. R., Kumar Joshi, S., & Greenwell, H. C. (2023). Investigating groundwater recharge using hydrogen and oxygen stable isotopes in Kabul city, a semi-arid region. Journal of Hydrology, 626, Article 130187. https://doi.org/10.1016/j.jhydrol.2023.130187

There are significant concerns about the sustainability of groundwater, and the inhabitants that depend on it, due to rapid groundwater depletion from the alluvium aquifers in Kabul city. Sustainable groundwater management in Kabul requires an unders... Read More about Investigating groundwater recharge using hydrogen and oxygen stable isotopes in Kabul city, a semi-arid region.

Retention and transport of PFOA and its fluorinated substitute, GenX, through water-saturated soil columns (2023)
Journal Article
Liu, G., Usman, M., Luo, T., Biard, P., Lin, K., Greenwell, H. C., & Hanna, K. (2023). Retention and transport of PFOA and its fluorinated substitute, GenX, through water-saturated soil columns. Environmental Pollution, 337, Article 122530. https://doi.org/10.1016/j.envpol.2023.122530

Perfluoro-2-propoxypropanoic acid (GenX) has emerged as a substitute for perfluorooctanoic acid (PFOA) especially since PFOA was listed among the persistent organic pollutants (POPs) by the Stockholm Convention in 2019. However, limited knowledge exi... Read More about Retention and transport of PFOA and its fluorinated substitute, GenX, through water-saturated soil columns.

Determinants of household safe drinking water practices in Kabul, Afghanistan: New insights from behavioural survey data (2023)
Journal Article
Hamidi, M. D., Haenssgen, M. J., & Greenwell, H. C. (2023). Determinants of household safe drinking water practices in Kabul, Afghanistan: New insights from behavioural survey data. Water Research, 244, Article 120521. https://doi.org/10.1016/j.watres.2023.120521

More than 2 billion people worldwide lack access to safe drinking water. Household water treatment (HWT) is an interim option for reducing the risk of water born disease. Understanding the factors that influence HWT behaviour is crucial for deliverin...

Swelling of compacted bentonite in organic solvents: Correlation of rate and extent of swelling with solvent properties (2023)
Journal Article
Erdogan, A. R., Whitford, A. C., Underwood, T. R., Sellick, C., Patel, R., Skipper, N. T., & Greenwell, H. C. (2023). Swelling of compacted bentonite in organic solvents: Correlation of rate and extent of swelling with solvent properties. Applied Clay Science, 241, https://doi.org/10.1016/j.clay.2023.107000

The swelling of clay minerals within shale formations during oil and gas exploration, and within compacted bentonite barriers for radioactive waste containment, presents a number of challenges to operators. Whilst much work has been devoted to unders... Read More about Swelling of compacted bentonite in organic solvents: Correlation of rate and extent of swelling with solvent properties.
