The semi-arid climate of the north-east of Mexico requires careful management of water resources in order to satisfy the demands of the population from the limited supply of groundwater resources in the region. These water resources are vulnerable to accidents or spills of hydrocarbons in places of collection, transport, or storage of combustibles, such as gas, petroleum, or derivatives. When a leak is detected in a pipeline or storage tank, precise mitigation steps are taken to eliminate potential sources of contamination of soil and groundwater and, in accordance with relevant Mexican standards, studies are undertaken to evaluate the affected sites, to determine the extent of contamination, and to select and implement the appropriate technology for restoring the contaminated site.
