HUBUNGAN ANTARA JARAK SUMUR GALI TERHADAP KADAR KADMIUM (CD), TIMBAL (PB) DAN MERKURI (HG) AIR SUMUR GALI DI SEKITAR TPA TROKETON KABUPATEN KLATEN

Abstract

The buffer zone and limited cultivation zone of the TPA Troketon are used as vegetable fields, where in these zones can be polluted by leachate containing non-essential metals (Hg, Pb, Cd, etc.). Non-essential heavy metals are toxic when consumed. Non-essential heavy metals are absorbed into plant tissues, so water for watering vegetable crops must be free from heavy metal content. However, farmers use water from wells dug around the TPA to water the vegetable crops in their fields. Based on the description above, the authors conducted research on the relationship between the distance of the dug wells and the levels of Cadmium, Lead and Mercury in the dug well water around the TPA Troketon.
This study aims to determine the effect of the distance dug wells on the TPA with the metal content of Cadmium, Lead and Mercury in the dug well water which is located in a straight line with the TPA and the IPL output flow. This research was conducted by checking the levels of Cadmium, Lead and Mercury in the laboratory and then the results were compared with the distance of the well to the landfill by analysis using SPSS.
The results of the analysis of the relationship between well distance and lead levels in dug well water show a negative correlation with a coefficient value of -0.565 or have a relationship but not significant and the effect of distance with lead levels is 35.6%, while Mercury metal in dug well water shows correlation with coefficient value of 0.512 or having a relationship but not significant and the effect of distance with mercury levels of 26.2%. As for the metal content of Cadmium, the tool cannot read in more detail, so a correlation analysis is not carried out. The levels of heavy metals analyzed in well water are still below the permissible threshold.
