| Abstract: | A model has been developed to predict the origin of uncontrolled water flows. For this purpose, we analysed a total of 52
elements using ICP techniques on 72 water samples in all: 40 of them from leaks in the drinking water supply network and the
remaining 32 from groundwater outcrops. The study focused on the cases registered within the Alicante town limits (Spain).
The use of multivariate statistical classification tools such as discriminant analysis made it possible not only to reduce
the number of analytes, but also to design a predictive model capable of assigning the group to which a new sample belongs.
The elements that comprise the model are B, Mn, Te, Ce, Re, Sr, Li and Tl. Given the concentration of each element in the
sample, the model can assign its precedence with a total success rate higher than 94%. |
