Abstract

This research about water quality testing on unconventional mining land in Merawang District,
Bangka Regency to be used as a water source for fulfilling daily needs for the surrounding
community.Sampling is done by purposive sampling by taking into account the consideration
of the condition and state of the landscape from the research area. The sample points were
taken as many as 2 samples with different conditions where sample 1 was obtained from the
water under the results of the dominant tin mine tailings in the form of sandstone and clay
stones and sample 2 from the water under the results of tin mine tailings in the form of kaolin.
The taking distance from the two samples is close to about 5 Km. From the results of field
data collection and laboratory analysis, the pH value in sample 1 was 5.71 and sample 2 was
5.57, TSS had a value in sample 1 of 7 mg / L and sample 2 of 8 mg / L, while the TDS value
in sample 1 was 92 mg / L and sample 2 was 8 mg / L. Whereas from laboratory analysis of
dissolved metals obtained values in sample-1 and sample-2 in the form of copper (Cu) have
the same value of 0.0153 and lead (Zn) 0.0531 while sample-2 value of lead dissolved metal
(Zn) is 0, 0977. From the chemical and physical parameters and analysis of dissolved metals
if based on the Minister of Health Regulation No. 416 ,1990 about Water Quality
Requirements and Supervision and Government Regulation No. 82, 2001 about
Management of Water Quality and Water Pollution Control is still classified under the quality
book and is determined by the value of the Pollution Index based (IPj) on the Decree of the
Minister of Environment Number 115,2003 about Guidelines for Determining the Status of
Water Quality. This method is used to determine the level of pollution relative to permitted
water quality parameters. The results obtained indicate that the water quality in the two
samples is categorized as inappropriate (light polluted) as a drinking water quality
requirement because it has a pollution index value for designation (IPj ) sample-1 was 2.15
and sample-2 was 1.86.
