INTRODUCTION AND LITERATURE REVIEW
Phosphorus is usually present in natural water as phosphate and is an essential element of life, phosphate can come from fertilizers, human or animal wastes, soaps or detergents and industrial waste.[1] When too much phosphorus becomes available, plant grows rapidly.[1] Phosphate that enter a stream may cause algae to multiply and grow quickly, this may result in an algae bloom. Algae bloom are thick layers of green slime that cover the surface of ponds or slow moving stream, algae bloom are harmful to most aquatic organisms.[1] They cause a decrease in the dissolved oxygen level of the water, by preventing waves and surface of the water from coming into contact with the air which provides the main source of oxygen for the water.[2] Their dark colour absorbs more heat energy from sunlight causing the water temperature to rise.[2] Plants which grow fast, die fast and sink to the bottom, of the water body; are decomposed by bacteria increasing the biological oxygen demand (BOD). All these factors combined to cause oxygen level in the water to decrease rapidly. This can result in fish kill and the death of many aquatic organism.[2]
AIMS OF STUDY
Ihiala local government and Uli town could be said to be a lowland area and a non-industrialized area, but the establishment of the Anambra State University has brought about rapid development as well as population explosion
As a result, it has been suspected that there are certain activities that may bring pollution in the source of water in Ihiala and Uli town e.g. phosphate pollution. However, it becomes imperative and important to assess these major sources of water pollution by phosphate (Atamiri river) in anambra State and to know the level of their pollution either they are good for the domestic purpose or not, and how they could be subjected to the treatment so as to avert the various adverse health implications.
It is very important to analyse solvent water because it contain a large number of phosphate or pollutant which are necessary to be checked before the water is used for any sperciic purpose.
