Abstract
. Different sa 1ple of gr u. ndwate. r were analyse.d from.

microbiological. point or view . some of industrial was)e-water samples were also eJCamined. Data
<lbtained from chemical nalysis showed that all examined parameters were found within dle
limits of the international law. 1l1e analysis of heavy metals of
ind strial wastes suggests th’ar’ .the valu s ofe a.mined heavy etals, i. e. pb, cu: Fe
. . .
and Mn were also in all wed limits. Tile microbiological !nvestigation showed presence of
’different microorganisms by using. different cultivation· media. Tile absence of pathogenic
bacteria either for groundwater or industrial waite-water was detected.
The ·bacterial treatment of industrial waste-wate leads to heavy metals reduction up to
. .
mdre than 50% in SO.!lJ cases. The possibility to produC.e.sqme bacterial enzymes from
industrial waste-water as a result of bacterial growth was.also achieved.”J;his work
