l years 2015, and the nature of all that fe 2,89 mg / l years 2016.This study aims to to investigate the extent to a combination of a sieve sand slow with the media sand of the zeolite, charcoal hand across his, sand and gravel.In a reduction of the nature of all that substance as iron ( fe ) water from the wells dug out of the people by keeping the use of a sieve sand slow in the work area of the PuskesmasLasi Kabupaten Agam years 2017.Where is this report is written with two types of the test and been approved treatment pt pgn promised to supply a sieve 1 with medium sand of the zeolite 10 police post cm grand cinema, charcoal hand across his 10 police post cm grand cinema, sand 3 cm keikil 2 cm and sifting the 2 with medium sand of the zeolite 40 police post cm grand cinema, charcoal hand across his 15 police post cm grand cinema, sand 4 police post cm grand cinema, gravel 3 police post cm grand cinema.Based on the research be made known be
that the level of substance as iron ( fe ) in water or dug wells is 3,72 mg / l, after filtering these chareges in the future 1 rata-rata 0.7512 mg /l , and after sifting 2 is 0.4450 mg / l.With pvalue 0,007. There are differences between the research rata-rata filtered by sifting firts.This means that the combination is more effective than filtering filtering two with combinations of filtering media sand of the zeolite 40 cm, charcoal hand across 15 cm, sand 4 cm, gravel 3 cm.
