Causing the pollution of rivers, canals, causing pollution to the river include : 1. Wastewater from home. Shops and office buildings, residential community with several neighborhood homes or commercial buildings. All require water for consumption. And usable for other purposes, this is the amount of water used, the quantity of the water out. Wastewater is mostly water from the toilet and the toilet and washing area. Which consists of organic soaps, detergents, organic food waste, grease and other contaminants in effluents of these substances on the canal flows into the mother. Would effect two major boosts First Supplement to aquatic plants and animals. The plants and animals increased. When plants and animals die away. Will cause an increase in organic matter in the water. Organic matter from wastewater and caused this increase. If there is a lot to be digested by aerobic bacteria contained in the water. It will take the oxygen dissolved in the water used at a higher rate than the rate at which oxygen dissolved in the water. Conditions caused by lack of oxygen The environment-friendly Anaerobic bacteria decompose the organic matter further. The water turned black, foul-smelling substances mixed with other substances, such as inorganic to add a higher volume. Water quality standards and not to waste utilities. Also, if the effluent contains various pathogens such as bacteria and viruses harmful to cause disease activities such as washing or dishwashing add pollution to water sources 2. Wastewater from industrial wastewater effluents from industries including manufacturing systems. Cooling System Office and residential buildings Shops and cafeterias substance that could be mixed organic compounds, inorganic acids, alkalis, chemicals, heavy metals are toxic, radioactive soil and other sewage. When dumped into rivers. Will increase the amount of these substances or toxic to organisms in the water. The putrid smell and unsightly color 3. Fertilizers used in agriculture, the main fertilizer used in agriculture, including nitrogen and phosphorus. Phosphorus in the form of phosphate can be attached to the soil. So there is a minority that flows with water. Therefore, substances that cause problems are nitrogen. Fertilizer use most often put together far more than the plant will be used up. When it rains the water will leach out nitrogen flow to the surface. Down to the river Allows algae to grow a lot. Water color, smell and taste when these algae die down. It makes the water putrid and phenolic higher. White fog floating on the surface 4. Soil erosion in the catchment area of some reservoirs, such as macular degeneration and erosion of soil. The water has a high turbidity, color, odor and taste of the erosion of top soil. Cause pollution to the river was five. Livestock livestock If pets eat grass to cover soil, excessive soil erosion, water when it rains. When water is flowing into the sources of the problem, as well as Article 4 The dung will flow into the river make organic nitrogen and phosphorus. Problems as well as 1 and 3 6. pesticides and herbicides , pesticides and herbicides, most of the chemicals are sometimes poisonous. When leached into the water. It is toxic to plant and animal life in the water. If we apply it to dangerous toxins with seven. Wildfire If a wildfire in the area of origin makes a waste water sludge, ash, sand and other pollutants flowing into the water a lot. This will adversely affect the quality of water to the living. It may be a reservoir or river silted due to accumulation of ash and sludge is different. Any water to wash the affected area wildfires. Waste and pollutants are mixed. The water was shallow 8. The lack of control over land use , land use side, or around water sources, lack of control or assignment. Would cause detriment to the quality of water, so it should be delimited or not to extend the plant communities along the water, bring water to use in the water.
