Abstract
This paper presents the results of lead content tests obtained during the
underground and surface water monitoring in the area of municipal landfill in
Jaworzno (Sląskie voivodship, Poland). The appearance of high lead contents in
the specific monitoring points was related with environmental data, the
geological structure of the area in question and geo-chemical properties of the
water bearing Triassic rocks. The over tenfold increase of lead contents (in the
range from 0,01 mg/dm3 to 0,1 mg/dm3) was correlated with the extremely low
level of underground water. This paper takes into consideration the possibility of
occurrence of naturally over-normative lead contents in underground water.
Based upon the geo-chemical test results it was stated that the increased content
of lead in underground water is probably related to oxidization of ore materials
that appear naturally in Triassic dolomites and contain lead. These minerals,
initially in the saturation zone, due to the lowering of underground water level
were covered by the aeration zone and from being hardly soluble they migrated
toward easily soluble. Such a sudden increase of lead contents until the standards
for drinking water are exceeded may result in harmful effects for human health.
Keywords: lead concentration, lead in underground water.
1 Introduction
Monitoring of underground water quality in the carbonate Triassic series within
the area of municipal landfill in Jaworzno has been carried out in a continuous
manner since June 2000. Water samples are taken, among others, from three
piezometers prepared for determination of the impact of the municipal landfill on
the quality of underground water. The researches cover with their scope a range
of physico-chemical parameters, including lead contents. An increased content of
