摘要：Optimum PO 4 -P level in surface and ground water is essential for maintaining good health and environment. In this study, the PO 4 -P level was measured for 148 different water samples collected from ponds, supply tape and tube-well of 8 different areas of Rajshahi City Corporation. All the sites of surface water bodies crossed the United States Environmental Protection Agency (USEPA) criterion of 0.01-0.03 mg L -1 PO 4 –P to be free from eutrophication. Among the samples, 4.2% were within the range (0.025-0.1 mg L -1 ) of onset of eutrophication while 95.8% crossed the hyper-eutrophication level (> 0.10 mg L -1 ). However, most of the ground (83.1%) and tap (92.7%) water were excellent in quality for drinking with respect to PO 4 –P level (<1 mg L -1 ). Only 15.3% of ground water and 7.3% of tap water were good quality and a negligible amount (1.6%) of ground water was fair quality. J. Environ. Sci. & Natural Resources, 8(1): 129-133 2015
