In-situ Remediation of Shallow Aquifer Pollution

In-situ Remediation of Shallow Aquifer Pollution

Improvement of urban and rural infrastructure such as road construction in particular in many developing countries has increased pollution stress on groundwater quality. For example, borrow pits from where materials were collected for road projects are usually abandoned instead of reclaimed. Soon after, these abandoned borrow pits become urban waste disposal pits. Aquifer pollution stress arises as the pits become point sources of groundwater pollution in the area or regions where water table is near surface. Again, lack of storm water management during road construction and other open engineering sites such as mechanic villages causes continuous enrichment of pollutants, such as toxic metals and organics, in surface water and groundwater.
