ABSTRACT
Tika Handes

Water is one of the primary human needs. Well water is one of the
sources of water used to meet daily needs such as drinking, cooking,
washing and others. This study aims to determine whether there is metal
content of Cd, Cr, Cu and Pb as well as the metal consentration in well
water around the Dan Liris factory Sukoharjo.
This research is a descriptive experiment conducted by identifying
qualitatively and quantitatively. Quantitative identification using atomic
absorption spectrophotometry (AAS). Samples were taken at a distance of
3 points, namely a distance of 100 meters (sample A), a distance of 200
meters (sample B), and a distance of 500 meters (sample C) from Dan
Liris Factory.
The results showed that the metal contentration in well water A
was 0.0007 mg / L of Cd, 0.0001 mg / L of Cr, 0.003 mg / L of Cu and
0.051 mg / L of Pb. In well water B, metal contentration of C is 0.0001 mg
/ L, Cr metal is 0.0026 mg / L, Cu metal is 0.001 mg / L. and Pb metal
0.008 mg / L. In well water Cd metal contentration was kurang dari0.00002 mg / L,
Cr metal was 0.0025 mg / L, Cu metal
kurang dari 0.00029 mg / L and Pb metal was 0.009 mg / L. Based on Permenkes
Number 32 of 2017 concerning environmental health quality standards
and water health requirements, the levels of these metals are still within
the required limits so that the well water around the Dan Liris factory
Sukoharjo is suitable for consumption and use for daily needs.
