Methods for quantification and evaluation of groundwater quality grade by using statistical approaches

摘要

The present invention relates to a method for quantifying a contamination grade of a groundwater quality monitoring network and evaluating a groundwater quality grade using data of the groundwater quality monitoring network which is installed and operated by the Ministry of Environment. The present invention provides a method for quantifying a contamination grade of a national groundwater quality monitoring network and evaluating a groundwater quality grade using statistical analysis, which statistically analyzes concentration change data monitored by a groundwater quality monitoring network, performs investigation of the frequency of water quality standard violations, average concentration analysis, and trend analysis for data of each point of the groundwater quality monitoring network, quantifies contamination grades using the results of the analysis, and evaluates groundwater quality grades by item, region, use, and drinking purpose based on the quantification of the contamination grades.
