The highlights of the article are:
- We assess groundwater recharge through a pervasive layer of floodplain muds.
- Modelled groundwater flow paths were consistent with tritium dating.
- The clay layer did not prevent recharge because of macropores and cracks.
- Fine-grained floodplain soils do not necessarily protect underlying aquifers from pollution.
- Combining multiple techniques gives more confidence in recharge estimates.
