Air merupakan komponen utama baik dalam tanaman maupun hewan termasuk manusia, masyarakat di Kabupaten Bantul, khususnya Pedukuhan Bantul Krajan, Desa Bantul, Kecamatan Bantul, Bantul, Daerah ...Istimewa Yogyakarta memanfaatkan sumur sebagai sumber utama persediaan air bersih. Masalah yang sering dihadapi oleh masyarakat yaitu tingginya kadar besi dan mangan di dalam air yang menyebabkan kualitas fisik air menurun, air menjadi keruh dan berbau amis. Penelitian ini bertujuan untuk mengetahui penurunan kandungan Besi (Fe), Mangan (Mn) dan Kekeruhan pada air sumur gali dengan pengolahan air sederhana dan manfaat pasir vulkanik sebagai media filtrasi terhadap penurunan kandungan Besi (Fe), Mangan (Mn) dan Kekeruhan pada air sumur gali. Penelitian ini merupakan penelitian Experiment dengan desain penelitian Pre test - Post test with Control Group Design menggunakan 5 pengulangan. Sedangkan untuk menguji hipotesis data yang diperoleh diuji secara deskriptif yang kemudian diuji secara analitik menggunakan statistik uji T-test terikat dengan program SPSS 16.0 for Windows. Hasil penelitian dari pengolahan air sederhana menggunakan media pasir vulkanik mampu menurunkan kandungan Fe sebesar 1,34 mg/l, kandungan Mn sebesar 0,6 mg/l dan penurunan kekeruhan sebesar 11,51 NTU. Berdasarkan pengujian statistik dinyatakan bahwa ada penurunan yang bermakna antara pretest dan posttest kadar besi (Fe), mangan (Mn) dan kekeruhan yang ditunjukkan dengan nilai Sig. < 0,05. Dengan demikian diketahui bahwa untuk menghilangkan zat besi, mangan dan kekeruhan yang berbentuk senyawa organik dan koloid cukup dilakukan pengolahan air sederhana yaitu koagulasi dilanjutkan dengan proses filtrasi menggunakan media pasir vulkanik yang memiliki sifat porous, mudah diperoleh dan harganya relatif murah.
