Perilaku masyarakat yang tidak mengolah kotoran ayam dapat mempengaruhi parameter amoniak melebihi baku mutu karena kotoran ayam membusuk dan mengalir ke sungai. Perilaku masyarakat yang mengambil tanah dari bukit/gunung tidak mempengaruhi parameter TSS karena dipengaruhi mengambil tanah dari bukit/gunung dilakukan pada curah hujan menurun/kemarau. Perilaku masyarakat yang menambang pasir di sungai mempengaruhi parameter amoniak melebihi baku mutu karena air limbah domestik yang organik dan kotoran ayam membusuk yang telah tertimbun lama di dasar sungai akan terangkat.
