The most important natural resource which cannot be optimally used and sustained unless its quality is
properly assessed, is groundwater. In the present study, the physicochemical variations of groundwater
from the area of an chemical platform were determinate. The physicochemical parameters determined for
the groundwater were evaluated by comparing the results obtained with the the limits allowed under
current legislation. For this study were examining 16 drillings for a period of five years. Water samples were
collected quarterly from each sampling point in the study. The physico-chemical quality indicators analyzed
for each source were: pH, chlorides, sulfates, bicarbonates, carbonates, sodium, calcium, magnesium,
ammonium, filterable residue, suspended matter, mercury and CCO-Mn.Interpretation of physicochemical
data revealed that groundwaters studied was neutral to slightly alkaline. The cations such as sodium (Na+)
for all groundwaters studied it was in general found above the limit imposed under the laws in vigor in
almost all studied drillings except drillings generally located upstream of the industrial platform. The anions
such as chlorides (Cl-) exceeded, in general, the limit allowed under current legislation. The filterable
residue concentration was observed in all the studied drillings and the parameter such as sulfate (SO42-),
were within the limit allowed under current legislation for the most all studied drillings, for the whole period
investigated. In general, the sulfate quality indicator exceeds the required limit, for drilling located
downstream and in vicinity of the chemical platform
