摘要：Natural waters vary in chemical composition and the factors controlling the composition include physical, chemical and biological processes. Water is one of the most important natural resources for all the living organisms because it is required for various metabolic activities. In addition, water is required for various domestic purposes, irrigation and power generation and the industries. Amongst various organic components, the iron and manganese are an important trace metal required for all the biological systems. The occurrence of iron and manganese, in the present study, was reported from Ramgarh Lake in Gorakhpur, India. Two sampling stations were selected for the present study. The iron and manganese have several effects due to their high concentration. The study was carried out for one year (January 2017 to December 2017). The significance of iron and manganese is discussed in the present investigation.
