Master Plan on Groundwater Quality Management (2012-2021)
As popular interest in water grows because contamination sources diversify with intensifying drought due to climate change, and various disasters and accidents such as the outbreak of foot-and-mouth disease, nuclear power plant disaster in Fukushima of Japan, clean and safe groundwater is drawing more spotlight. Since the enactment of the relevant law in 1993, however, groundwater management has been done with a focus on water quantity management, which has been focused on dealing with impending issues. Master Plan on Groundwater Quality Management, to be implemented for a decade (2012-2021), was established with a view to presenting a proactive vision and policy direction in securing clean and safe groundwater and building a framework for using groundwater as strategic resource of the future in a sustainable way.
Facilities using and Development Groundwater
Groundwater Act stipulates that when a person wants to develop and use groundwater, the person must get authorization from or register with city or county mayor or ward chief, with authorization or registration depending on the water pumping capacity of the facility and the diameter of the discharge pipe. In terms of authorization, a person who wants to develop or use groundwater must conduct an investigation of the impact of groundwater prior to application for authorization.
As of late 2011, 3.91 billion m3/year of groundwater was used in 145 million locations across the country. Compared to the previous year, this meant an increase of about 70,000 holes and about 100 million m3 of groundwater used. Classified by uses, 1.93 billion m3 (49%) of farming & fishery water, 1.78 billion m3 (46%) of residential water, and 170 million m3 (4%) were used. By region, Jeonnam used the largest amount of 560 million m3 per year, while Seoul used the smallest amount of 220 million m3 per year. By used water quantity per area, Jeju was the largest and Gangwon was the smalles
Groundwater Contamination Prevention Facilities
Groundwater Act stipulates that anyone who develops or uses groundwater is responsible for ex post facto management including the maintenance of facilities for groundwater development & use and installing groundwater contamination prevention facilities for groundwater quality conservation, but contamination of groundwater is a concerning matter because of the insufficient contamination prevention facilities or unsatisfactory ex post facto management. This has led to the joint survey of the facilities for groundwater development & use designed to upgrade the obligation to install facilities for preventing contamination with regard to development & use of groundwater and the amendment of the Rules on Groundwater Quality Conservation etc.
Public Drinking Water Facilities Designation & Management System
Developed with the purpose of supplying drinking water to a multiple number of persons or naturally created water springs, washing places watered by spring, and wells were designated as public drinking water facilities, and the places are subject to water quality inspection at least once a quarter (every month in the third quarter).
Most of "Inappropriate" items come from the microbial criteria such as Ordinary Bacteria and Total Coliforms, and the major causes of "Inappropriate" items are inflow of nearby pollutants in rainy season precipitation and inflow of wild animal excreta. Those facilities found inappropriate by water quality standards are subject to such adequate measures as repairs, reinspection, or closure in compliance with Public Drinking Water Facilities Management Guideline.
Establishment of Soil & Groundwater Information System (SGIS)
Starting in 2004, Soil & Groundwater Information System was developed and created to enhance of information sharing on soil & groundwater among related areas and service to people with a view to applying them to configuration of nationwide groundwater contamination and restoration projects and upgrading operational productivity and organizational competitiveness through the advancement of soil & groundwater management, systematic information management, and creation of a basis for processing and utilization. The system provides the following information.
- Support for the work of installing and operating monitoring networks
- Search of data for monitoring networks and contamination status
- Search of data for soil monitoring networks and contamination status
- Search of data for soil status and contamination status
- Search of data for formal examination and purification of soil
- Search of data for information on soil & groundwater contamination sources
- Search of location of soil & groundwater monitoring networks
- Status of Target Facilities of Specific Soil Contamination Management and results of contamination test
