Hard water, or water with a high level of total hardness, if consumed in long

waterwhich sold in Kayutangi Banjarmasin and to compare it with the standard
parameter of total hardness in Permenkes 492/Menkes/IV/2010 which is 500 mg/L in
maximum. There were 16 samples in this study that taken from refill drinking

complexometry titration method with Na2-EDTA as titrant and Eriochrome Black T
as indicator. The results showed that the ranges of total hardness level of 16
samples that determined between 35,64 – 99,00 mg/L which is suitable with the
