Additional uses for algae found in water supplies -- 12. water unsafe for human use and disrupts aquatic ecosystems. Firstly, enrichments of the algal nutrients in water through organic effluents may selectively stimulate the growth of algal species producing massive surface growths or 'blooms' that in turn reduce . They prefer still, warm, nutrient-rich water ( Reynolds, 1998 ). Water is considered to be polluted if certain substances or physical factors affect the quality of water and functioning of ecosystems and, as a result, the use of water for particular purposes is restricted. Water pollution is the release of substances into bodies of water that makes. 2 . Across the country, pollution from farms is one of the primary reasons water is no longer clean or safe. Pollution of surface water has become one of the most important environmental problems. Bogadi Lake was least polluted and Karanji Lakes and Mandakahalli Lake were polluted. Water pollution is the addition/presence of undesirable substances to/in water such as organic, inorganic, biological, radiological, heat, which degrades the quality of water so that it becomes unfit for use'.

Water pollution can destroy the entire ecosystem and its living organisms. Procedures for enumeration of algae . cause water pollution by promoting excessive algae growth, particularly in lakes. 1 World inventory of fisheries. In urban waste treated is a mixture of the preceding types of areas, domestic wastes are collocated in sewage pipes and pollutants, thus greatly complicating treatment and control transmitted to control location either for treatment or procedures (Nesaratnam, 2014). This may be expected to affect water quality issues, such as harmful algal blooms, and the transfer of nutrients to support fisheries. States reported that more than half of all lakes were affected.

Agriculture is the leading source of pollution of rivers and streams surveyed by U.S. government experts, according to the Environmental Protection Agency. Microalgal cultures offer an interesting alternative for waste water treatment (urban, industrial or agricultural effluents) because they provide a tertiary biotreatment coupled with the production of potentially valuable biomass, which can be used for several purposes. It enhances the growth of algae in water which leads to depletion of oxygen in water. Some small streams depend on leaves falling from nearby trees as an energy source. Relationship of Algae to Water Pollution and Waste Water Treatment 351 [7] Brook, A.J. This causes water pollution by promoting algae growth particularly in Lakes.
