The so-called groundwater quality monitoring, this process is to monitor and determine the types and concentrations of harmful substances in groundwater, and then grasp the groundwater quality and pollution trends. This chapter is simply to understand the relevant knowledge of groundwater quality monitoring with you!
What are the Groundwater Monitoring Programs?
There are ammonia nitrogen, nitrous nitrogen, nitrous nitrogen, total hardness, pH value, oxygen consumption, potassium, sodium, calcium, magnesium, bicarbonate, sulfate, chloride ion, phenol, mercury, arsenic, cadmium, total chromium, oil, coliform, total number of bacteria and other items. Groundwater monitoring distribution can be determined according to the local hydrogeological conditions, groundwater development and utilization, industrial pollution sources distribution and other factors. Among them, the deep well problem, which is usually in the existing industrial water or civil water Wells, will choose a representative well location for water quality monitoring, under normal circumstances, groundwater high water period, low water period and normal water period are sampled about 1 to 2 times a year.
What is the Role of Monitoring Groundwater Quality?
Early warning systems for the protection of water supply sources;
Monitoring the rising trend of pollutant concentration;
Evaluation of the effectiveness of pollution control measures;
Validation of pollution risks and evaluation results;
Numerical model for correction of pollutant transport;
Tracing groundwater flow;
Diagnose groundwater ring Pei barbarization.
Understand the Steps of the Groundwater quality monitoring network!
The method of designing the water quality monitoring network depends on the purpose of monitoring. The general steps are: determine the characteristics of the detection area; Define the purpose of groundwater quality monitoring; Establishing hydrogeological conceptual model; Groundwater pollution assessment; Investigation of water pollution sources; Risk assessment of water pollution; Water quality monitoring network design problems.
