Impact of the Mining Activity on the Water Quality in Peru Applying the Fuzzy Logic with the Grey Clustering Method

Abstract: Mining activity in the department of Junín, Peru, is intense, due to the great existing mining-metallic potential that exists in the place, the Yauli and Andaychagua rivers, located in the Yauli Province, belonging to Junín, receive a large volume of discharges causing deterioration in the quality of the water of these rivers. To evaluate this quality in an integral way, fuzzy logic will be applied with the Grey Clustering methodology, defining the central point triangular whitening weight functions (CTWF), ha… Show more

“…(1) Gray system The so-called gray system is relative to the white system and the black system. If all the information of a system, such as architecture, influencing factors, and the interaction between influencing factors, is unknown, the system is called a black system; on the contrary, when a system can show enough and perfect The amount of information, the internal and external structures are obvious, the influencing factors and mechanism of action in the system are clear, and there is an obvious development and change law, which is easy to qualitatively analyze and quantitatively describe the system, it is called a white system [4][5] . The gray system is a kind of "half black and half white" system, that is, the system has some characteristics or the information is exposed and known to people, but there are still some important information hidden in the system.…”

“…In the present investigation, a new case study is developed applying the grey clustering methodology used by [11], [12]. Where the water quality was analyzed for category 3 (water intended for irrigation of vegetables and for animal consumption) according to with the Peruvian standard of environmental quality, on the other hand [13] used the grey clustering methodology to determine air quality and [14] used it with physicochemical parameters.…”
