What do You Know about water-education.....Water-education is very essential to develop the water quality as the water is fundamental for human existence. The early people recognized only the important of water from quantity point view. The civilization start thinking how to utilize water to support agriculture, transportation, industries as well as drinking water. The recognition of water quality importance moved slowly, the early people was judged water quality only through physical senses of sight, taste, and smell. The water-education developed the chemical, biological, and medical sciences, were methods available to measure water quality and to determine its effects on human health and well being. Not until the mid nineteenth century that the relationship between human waste, drinking water, and disease was documented. Several more years intervened till this relationship become widely accepted and action taken against it. The story of Dr. Jhon Snow(1854) noted a high correlation between cholera cases and consumption of water from a well on Broad street. Also on 1900 the concept of waterborne disease was well accepted. The development of the science of water chemistry was paralleled with water microbiology, which help to find out many of chemicals used in the industries and agriculture have been identified in the drinking water supply. An effort to identify some chemical compound in trace quantity in many water supply, to determine their effect on human health was recently begun. Thus, the science of water quality will remain a challenge for scientist and engineers for years to come. water Quality Requirement Water quality requirements vary according to the proposed use of the water, for example
Water quality requirement should not be confused with water quality standard. Water quality requirements represent a known or assumed need and are based on the prior experience of the water user. But the water quality standard are a set by a governmental agency and represent a statutory requirement.
