One day I was standing on a mining waste dump in Ampoi Valley, Romania, watching an old man driving his cows toward the water in the small lake created from rain. This region's mining history dates to Roman times, 2000 years ago. I imagine the cows drink daily from that water. I thought: “If he knew how toxic that water is … if the community knew the distribution of the contamination in this valley, then they may try to avoid the worst places.” Less than a year later, Geoscientists Without Borders came to our attention. We formed a young and ambitious team of faculty and PhD students at the University of Bucharest to tackle the pollution problem in Ampoi Valley. The SEG Foundation awarded a Geoscientists Without Borders grant with funding provided by Schlumberger. Additional financing arrived from Prospectiuni SA (a geophysical and geological service company in southeastern Europe) which was impressed by the project and offered to be a part of the story.
evaluation of the longitudinal conductance S, can offer a relevant image regarding the protective capacity of a clayey aquifer overburden. Hence, this parameter gets a time dimension (Henriet, 1976), namely infiltration time. The integrated interpretation of the geophysical data sets can lead to an accurately determination of the thickness of the overburden. The resulted map which illustrates the spatial distribution of the Longitudinal Conductance emphasizes the week natural protection capacity of the phreatic aquifer – the main potable source for the inhabitants in Zlatna mining region.
The mining activities generate today the biggest pollution problems that the industry is facing. Zlatna mining region, Romania, was declared in the '90s the most polluted area in Europe. The primary goal of the study is to analyze the contamination in the studied area at the soil level, underground terrain, hydrological and hydrogeological systems, generated by the ore processing activities. The study is part of a project which further aims to guide the local communities as to which land is more favorable to the practice of agriculture and grazing of animals. The project team will search for solutions for identifying sources of potable water in the context of the polluted aquifers.
