Pengaruh Jarak Buangan Air Limbah Industri di Daerah Jaten-Karanganyar terhadap Kadar Chromium dalam Air dan Tanah Permukaan Saluran Air Pungkuk

Abstract

The purpose of this research was to know the effect of industry waste water distance in Jaten-Karanganyar on Cr concentration in the water and soils at Pungkuk waterworks, also to know Cr concentration on that waterworks. The kind of this research was explorative research. The independent variable was treatment of take some water and soils sample at 0 km, 0.5 km and 1 km distance from pollutant source at Pungkuk waterworks and control.

The result showed that distance where farther can affect Cr⁶⁺ concentration change in the soils and in the water were increase. The increasing of Cr⁶⁺ concentration change in the soils affected Cr⁶⁺ acumulation in the soils. The concentration of Cr⁶⁺ in the water has been influenced by value of water pH and EMC. Value of water pH also was influenced water EMC value. From sample analysis result showed that there was not polluted of heavy metal especially Cr⁶⁺ (between 0.017-0.093 ppm).
