Resumo(s)
A significant industrial development, associated with a demographic
expansion, occurred during the last decades of the XX century, in Loures valley, a region
located in the vicinities of Lisbon, the capital city of Portugal. This was accompanied
with an important modification of land use and occupation patterns, mainly the decrease
of the agricultural land.
One of the main consequences was the deterioration of the groundwater chemistry
observed in the shallow aquifer associated to Trancão river, a subsidiary of Tagus river.
Factorial Correspondence Analysis has been used to build a water quality index, for
evaluating the impact of the anthropogenic factors on groundwater of the shallow aquifer.
By analysing the kriged maps of the values of the index, it was possible to identify the
areas more sensitive to the anthropogenic impact.
