There was also some support for a much wider view of water resources and taking into account potable as well as non-potable groundwater in inventories of resources. It was clear that many aquifers, both in the United Kingdom and overseas, were underused and more adventurous methods of development would repay dividends. Examples were drawn from Iran where mining of groundwater would be essential for the exploitation of mineral resources. A further illustration from Tehran drew attention to the unusual situation in which lateral changes in permeability in the aquifer combined with supplementation of the groundwater resources from surface water led to the theoretical possibility of cyclical use of groundwater. The hazards of re-use of ground-water were stressed under such conditions.
Groundwater chemistry was discussed at length in relation to the development of deep, connate waters, groundwater recharge and the deep disposal of waste. Attention was drawn to the need to flush salts from irrigable lands, as for example in the land to be developed for agriculture by
