Water and mining conflicts in the information age

My father was an olive farmer and very active on the valley olive farmer association in Peru. In the eighties, there was a tailings spill that afected the river water and the irrigated lands. Based on what they could understand of contamination and water chemistry, they had the iniciative of taking water samples and show them to water authorities.

Soil cover system design for mine waste dumps

 

Surface water and groundwater surrounding a mining operation can be significantly affected by contaminated seepage from the Acid Rock Drainage (ARD) in the waste-dumps and tailings deposits. An evaluation for prevention and mitigation of environmental impacts generated by the DAR is necessary to minimize the impact to the environment.

Tailing and waste dump seepage evaluation and remediation

 

Current and historical mining activities have a seepage and waste-dumps legacy that are the concern for mining companies, population and regulatory authorities. Old waste-dumps have not been regulated and most of the old tailings have been deposited in soils without covering. Tailing deposits and waste-dumps should be analyzed in a particular way because of the ground, instalation details, mineralized body geology, mined type, weather and other parameters.

 

 

Geostatistics on water resources investigation

Before talking about the different researches that have had as main focus the water resources, I think it is necessary to explain first what geostatistics is.

Geostatistics is a type of statistics that is used in order to analyze and interpret geographically referenced data. It is not restricted to only work with point data, but can also work with GIS layers to explore spatial variation, improving generation of digital elevation models (DEM) and their respective simulations, optimization of spatial sampling, etc.
