ANALISA WARNA, KEKERUHAN, LOGAM Fe PADA AIR SUMUR BOR DI UPT LABORATORIUM KESEHATAN DAERAH MEDAN
Background and aims: Water needs to be protected in order to remain beneficial to human life and other living things. This understanding shows that water has a very strategic role and must remain available and sustainable. Color in water is caused by the presence of particles of decay from organic matter, natural metal ions (iron, manganese) plankton, humus. The objective of this study was to determine the physical quality of water - color, chemistry, turbidity and iron (Fe) content. Methods: This study was a descriptive survey with 27 samples. The research site was conducted at the Technical Services Unit of Water Chemistry Laboratory, Medan Regional Health Laboratory. Results: The results of the study of dyes in clean water samples that met the requirements were 81.48% and those that did not meet the requirements were 18.52%. Turbidity in clean water samples, all samples studied were 100% eligible. The level of iron (Fe) in the clean water sample of 96.89% meets the 11.11% requirement which is not eligible. Conclusions: Water well drills in Medan regional health laboratory meet standard requirements of minister of health regulation.
