River water is very much important for domestic, agriculture and industrial use in Bangladesh which is in critical condition from long time based on research data. During last 40 years, extreme pollution events occurred in peripheral rivers surrounding Dhaka city and Karnaphuli River in Chittagong city. Present data showed that other urban rivers are also in critical condition especially Korotoa, Teesta, Rupsha, Pashur and Padma. The pollutants flowing with water made a severe pollution in downstream areas of rivers. Metals concentrations in river water was found to be higher in dry season. Dissolve oxygen (DO) was nearly zero in Buriganga River and several points in Turag, Balu, Sitalakhya and Karnaphuli River. NO 3 - , NO 2 - and PO 4 3- pollution occurred in different rivers. Zn, Cu, Fe, Pb, Cd, Ni, Mn, As and Cr concentration was above drinking water standard in most of the river and some metals was even above irrigation standard in water from several rivers. Sediment data showed very much higher metal concentrations in most of the rivers especially peripheral rivers in Dhaka and Karnaphuli, Korotoa, Teesta, Rupsha and Meghna River. Metal concentrations in sediment was above US EPA threshold value in most of the rivers. Metal concentrations in fish and agricultural crops showed that bioaccumulations of metals had occurred. The concentration of metals showed the trend like: water

“…Industrial effluent containing reactive nitrogen and different heavy metals is a serious threat to human, plant, aquatic lives and ultimately to the total ecosystems. Release of untreated effluents to the environment is of great concern for the sustainable use of natural resources like soil and water which become degraded and creates negative impacts on crops, insect pests, and animal and human lives (Hossain et al, 2010;Eruola et al, 2011).…”

Agriculture in Bangladesh is characterized by crop, fishery and livestock sectors. Urea-N is used in all three sectors. Crop sector plays a dominant role in urea consumption to supply of food for ever burgeoning population. Application of inorganic N fertilizer definitely increased agricultural productivity. This however playing a significant role in altering global nutrient budget, water quality, greenhouse gas emission, and ultimately affecting the global climate. Though cropping intensity and use of N fertilizer have increased, yield plateauing is a concern for food security. Recovery efficiency of N rarely exceeds 30% in both crop and fish culture, while remaining reactive N is a global concern. Different industries have emerged in the last decade producing huge amounts of effluents discharging to the environment without treatment which appeared as a potential threat in damaging and disintegrating the environment. Resultant negative effect from application of large amount of organic and inorganic fertilizers and feeds in fishponds is a matter of boundless anxiety as it might act as a source of reactive N. Livestock sector comprising poultry and dairy produce huge amount of manure annually which is equivalent to 0.30 million tons of N and because of poor manure management reactive N is spreading in the environment. Reluctant attitudes on these crucial issues might bring a disaster through stopping natural ecosystem functions of the environment from where ‘U’ turn will rather be impossible. Adoption of resource conservation strategies, judicial and optimum use of N fertilizers in all agricultural sectors, improved management of livestock manure and industrial effluents are strongly recommended for environmental sustainability.

The industrial discharge carries significant level of contaminants to the surface water and ground water. Whereas the quality of freshwater is very vital because is highly use by human for drinking, bathing, agriculture and other needs. The presence of contaminants from industries within the water may reduce the yield of crops and the growth of plants; it is also harmful to the aquatic living organisms, it alters the surface water and ground water quality. Industrial pollution is one of the major factors causing degradation of the environment, affecting the water we use, the air we breathe and the soil we live on. Hence, the pollution of water is arguably the most serious threat to current human welfare. This paper review elucidates reasons of contamination of surface water by the industrial effluents, highlights major causes of ground water pollution; the work also indicates some industrial discharges and their contaminants.
