WATER QUALITY MONITORING
I. Introduction of monitoring water quality
1.1 Concept
Environmental monitoring is the measurement in accordance with standard methods, observe, assess and report on the quality of the environment in time, space, frequency regulation in motthoi long, in order to determine the status and trends of environmental changes in quality.
+ Water Environment Quality is assessed through: Characteristics of physical factors (turbidity, solids, color, radioactive, temperature), the concentration of inorganic SUBSTANCES, organic and microbial in water.
+ Composition and state aquatic populations in nuoc.Do determining the chemical and physical components are made with precision trust caonen the international environmental organizations and countries are using the chemical parameters, Lyde prescribed water quality standards.
The aquatic part by little immediate change when the water quality change and often large numbers cosai between monitoring bodies, monitoring methods should not have standards but often quidinh additional consideration, especially sensitive kinds at arm hydrological changes the water quality.
The assessment of changes in water quality most is assessing the impact of the incident onhiem water must be carried out through three components that make up lip truongnuoc.
Hydrographic
hydration Composition
Composition aquatic
To assess the quality of water and predict changes in water pollution , measurement can not all carried out hydrological parameters, chemical, physical, biological, but to select the specific parameters, dangduoc recognized and used in international documents
