Masalah penelitian ini adalah kontribusi limbah domestik terhadap kualitas air sungai Tondano-Sawangan Sulawesi Utara.  Penelitian ini bertujuan untuk mengkaji tentang kontribusi limbah domestik penduduk di bantaran sungai Sawangan terhadap kualitas air sungai Tondano-Sawangan Sulawesi Utara. Metode penelitian yang digunakan adalah deskriptif kuantitaf. Teknik pengumpulan data dikumpulkan dari hasil pengambilan sampel di dua lokasi dan perhitungan labolatorium dan dokumentasi yang ada dilapangan. Parameter yang diukur di laboratorium adalah derajat keasaman atau pH, Biochemilcal Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS), Amoniak, dan Total Coliform.  Hasil penelitian menunjukkan kualitas air Sungai Tondano-Sawangan mengalami penurunan kualitas dari hulu ke hilir yang disebabkan oleh limbah domestik penduduk. Parameter yang dominan memberikan kontribusi nilai indeks pencemar yang tinggi adalah parameter biologi yaitu total coliform. Pencemaran air yang disebabkan oleh kontaminasi limbah toilet merupakan masalah yang cukup serius, dikarenakan adanya potensi penularan penyakit oleh pathogen. Kandungan Total coliform yang terdapat pada air sungai bagian hulu sebesar 24200 MPN/100ml sedangkan bagian hilir sebesar 19900 MPN/100ml, sudah melebihi nilai ambang batas standar baku mutu sesuai Standar Nasional Indonesia. Batas maksimum Cemaran Total Coliform yaitu 3000 MPN/100ml, dengan demikian dapat dikatakan bahwa mutu air sungai Sawangan sudah tidak aman lagi untuk di konsumsi bagi masyarakat, namun untuk kegiatan rekreasi, tambak ikan, dan lain sebagainya masih aman. Parameter lain seperti BOD, COD, pH, TSS, Amonia, masih aman karena berada dibawah standar Baku Mutu.Kata Kunci: Limbah Domestik , Kualitas Air, Pencemaran Air, Baku Mutu

The assessment of river estuary physical erosion can be based on position and time distribution of velocity and sediment transport. The physical variables are partially or integratedly used to assess the flow characteristics. Analysis of the physical variables and their changes along the river estuary can show the process of sediment deposition in the estuary. Data distribution and flow physical variable profile will generate mathematical function of changes along the estuary. Spatially, this mathematical function will generate and determine the position of the material transport deposition (map of sediment deposition in along the estuary of the river). The material transport deposition map (based on the valueof (c0), presents the contours of c0 during the low tide (presented in the form of curves/ full line), while the contours of c0 during the high tide (is presented in the form of dashed lines). The concentration contour of material transport at high tide is at the position of 80 meters of c0 equals 1.35 grams per litter, at low tide c0 equals 1.36 grams per litter, and at the maximum high tide, almost all sediment is in the form of fine sand sediment deposited at the position of 0 meter up to the position of 280 meters, the c0 value is equal to 1.26 grams per litter. It can be seen in the contour map the shifting position or contour lines at low tide and high tide, and when the tide is shifted farther to the upstream of shoreline. Contour lines shift to the upstream 1004 Maxi Tendean direction of shoreline at high tide shows the position shift of deposition of material transport to the upstream direction. In this condition, the concentration of sediment in the form of fine sand at the maximum high tide, almost all of it is deposited at the location next to shoreline upstream.
