    This thesis concerns assessment of $Zn, Cd$ and $Pb$ migration in the Matilda River valley. Work presents the key informations about the aquatic environment this area. Selected heavy metals were characterized in terms of their forms of binding and geochemical properties. The parameters influencing the mobility of metals in the aquatic environment were specified. Studies were carried out on samples of groundwater and soil profiles collected in the Matilda River valley. Sequential extraction of heavy metals was carried out BCR method allows separating of the two most mobile forms of metals. The most mobile metal is $Cd$ and small amount $Pb$. A slight contamination of groundwater in the Matilda was found. Increased in some test points concentrations of $Zn, Cd$ and $Pb$ must be the results discharge into Matylda River of mine waters from the lead and zinc mine Matilda.
