During the 1960s it became a petrochemical complex, and by the 1980s environmental monitoring revealed high levels of organic contamination in the groundwater.
For each model, the composition of the groundwater and the host rock with which it interacts must be defined.
This could reflect a period of greater aridity, but may also indicate some saltwater contamination of regional groundwater.
This assumption is common practice in unsaturated groundwater flow.
This indicates that the impact of groundwater depletion on income becomes prominent as the severity of resource extraction increases.
A watershed development program aiming at recharging aquifers, facilitating sustainable groundwater use, is the focus of this study.
Even though the watershed development program facilitated physical access to the groundwater resource, economic access in terms of gross irrigated area is skewed.
Given the ecological conditions, individual investments in groundwater exploitation may prove to be costly and unsustainable.
