Solid wastes generated by the population of Linares were
deposited in the municipal landfill during the last 21 years. Water quality was analyzed in water
samples extracted from several hydraulic wells located near the landfill, as well as in areas
where other pollution sources exist (barite deposits, pig farms, septic tanks and latrines).
Taking several official norms as a basis the results showed contamination by total and suspended
solids, total and fecal coliforms, nitrates and DNAPLs (dense non aqueous phase liquids) such as
mercury, barium and arsenic. It was observed that main directions of the ground water have
influence in the migration of contaminants, determining that the most vulnerable zones are
located mainly downward the municipal landfill, in the same orientation that ground water flows.
