ABSTRACT

Background: Iron in rural ground water supplies is a common problem: its concent­ration level ranges from 0 to 50 mg/L, while WHO recommended level is <0.3 mg/L. The iron occurs na­turally in the aquifer but levels in groundwater can be increased by dissolution of ferrous bo­rehole and handpump components. Iron-bearing ground­water is often noticeably orange in co­lour, causing discoloration of laundry, and has an un­plea­sant taste, which is apparent in drin­­king and food preparation. There are only a few studies of fresh water shell (batissa vio­lacea ce­lebensis) as an alter­native to reduce the iron content in groundwater has not been done much.This study aimed to to test the effectiveness of fresh water shell (batissa violacea ce­le­ben­sis) in decreasing iron level in the ground water.

Subjects and Method: This was a quasi-experiment study before and after with no control design conducted at Wowawanggu village, Wua-wua sub-district, Kendari, South Sulawesi. A total sample of 3 boreholes was selected for this study by purposive sampling. The dependent va­riable was iron level in the ground water. The independ­ent variable was fresh water shell (ba­tissa violacea celebensis). Differences in mean bet­ween groups were tested by One Way ANOVA and post hoc test.

Result: Differences in mean between groups were statistically significant with iron level in the ground water in the fresh water shell (batissa violacea celebensis) groups lower than the ne­ga­tive control group.

Conclusion: Fresh water shell (batissa violacea celebensis) is effective to decrease iron level in the ground water.
