Analisis Kadar Kesadahan Total Pada Air Sumur dan Air PDAM Metode Kompleksometri di Kaliabang Bekasi

Abstract

Water is a natural resource that is very necessary for the life of many people. Good water is water that meets the requirements of physics, microbiology, chemistry. Chemically there is no water in the form of chemicals Arsenic, Iron, chloride, and hardness in the form of CaCO3. Hardness is a condition with excessive lime content in the water. Hardness with high concentrations consumed in the long term can be detrimental to health. Several factors that interfere with residents' wells are the presence of white sediment in the water which causes public health problems, and the frequent blockage of the pipeline used. The method used is the complexometric method, this kind of research is descriptive in nature. The results of checking the well water obtained Ca levels, namely 100 ppm and Mg, namely 61.44 ppm, while the results of checking tap water with Ca kadae were 150.2 ppm and Mg levels were 75.80 ppm. From the results of this study it can be concluded that well water and pump water can be used for consumption because they have a low hardness value.
