Abstract

Water is a vital need for human life. As a country that is rich in minerals, groundwater
in Indonesia often contains high levels of iron (Fe) and manganese (Mn). In water, these two
metals are always together. For humans both metals are important, but can also be toxic
(poisonous). Their presence in water can be detected laboratorally and can be recognized
organoleptically. With Fe or Mn concentration of at least 1 mg/L, the water tastes bittersour,
smells bad and is brownish yellow in color. In Sedayu 1 Hamlet, Sedayu Village,
Muntilan, residents complained about the appearance of brownish water in their wells. This
was suspected because of the Fe and Mn metals content which exceed the standard quality.
Therefore, water sample testing was carried out in three locations (well water 1, well water
2, and pond water) in the area. Some of the parameters tested were hardness, pH, Fe and
Mn metal content. The test results then were socialized to 30 residents. The value of
hardness, Fe and Mn metals in several locations were still above the permitted quality
standards. The residents were motivated to be more wary in the water treatment. The simple
method for processing of water contaminated with metals were by adding activated carbon
adsorbents and a heating process before it can consumed directly by residents.
