ABSTRACT

A study of ground water from several wells was carried out in Jasin, Melaka to determine its suitability for drinking and domestic used. Four times sampling trips (n=4) had been done between June and October, 2000. Water parameters determined were temperature, pH, conductivity, color, turbidity, total suspended solids (TSS), dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD), oil and grease (O&G), total dis­solved solids (TDS), nutrients and heavy metals (Cd, Cu, Pb, Mn and Fe). All selected methodology selected used were recommended by APHA (1995). The study indicated that the concentration of all parameters chosen were below the maximum values recommended by Malaysian Department of Health for drinking water quality except for certain heavy metals. Water Quality Index (WQI) calculated showed that the quality of water for many of the wells was of in Class III and not suitable for drinking before any extensive treatment.

ABSTRAK

Kajian kualiti air bawah tanah daripada beberapa perigi telah dijalankan di Jasin Melaka untuk melihat kesesuaiannya untuk kegunaan air minuman dan lain-lain aktiviti domestik. Sebanyak empat kali persampelan (n=4) telah dijalankan antara bulan Jun hingga Oktober, 2000. Parameter kualiti air yang ditentukan adalah suhu, pH, konduktiviti, warna, turbiditi, jumlah zarahan terampai (TSS), oksigen terlarut (DO), permintaan oksigen kimia (COD), permintaan oksigen biologi (BOD), minyak dan gris (O & G), jumlah zarahan terlarut, nutrien dan logam berat (Cd, Cu, Pb, Mn dan and Fe). Kesemua kaedah yang dipilih adalah kaedah yang dicadangkan oleh APHA (1995). Hasil kajian menunjukkan, kepekatan kebanyakan daripada param­eter yang dipilih adalah di bawah paras maksimum yang disarankan oleh Kementerian Kesihatan Malaysia untuk bekalan air minuman kecuali untuk beberapa logam berat. Pengiraan Indeks Kualiti Air (WQI) pula menunjukkan hampir kesemua air perigi berada dalam Kelas III yang tidak sesuai dijadikan air minuman sebelum rawatan ekstensif dijalankan.
