ASSESSMENT OF SUBSURFACE WATER SOURCES IN ISLAND OF SANTIAGO– CABO VERDE WITH EMPHASIS IN SPATIAL DISTRIBUTION OF RADON CONCENTRATION

Abstract

The study measures the subsurface water in-situ measurement for pH, electroconductivity and temperature, and the ex-situ measurement on 29 sampling points across the island, where water was collected on vials filled up with 10 ml cocktail, Optifluor O and Instafluor and for analyses the LSA technique was used. The goal is to explore the spatial heterogeneity of radon concentration and to try to find relationships with environmental factors.
