The view of monitoring stations

National Groundwater Monitoring Network

• Legal basis : Article 17 of the Groundwater Act
• The Period : 2016 ~ 2021
• The Host :MOLIT(an angency K-water)
• Goals : To install 530 monitoring stations by 2021
  • Currently(2015) have been installatied 402 monitoring stations

    

• Composition of groundwater monitoring station
  • monitoring for Bedrock aquifer well : Entire well being monitored (293 wells)
  • monitoring for The alluvial aquifer well : developed alluvial layer area (148 wells)
• A role of national Groundwater monitoring network
  • the key station in acquiring groundwater hydrological data of Korea
  • Observing and preventing groundwater hazards such as groundwater depletion, pollution, ground subsidence, and intrusion of seawater

Monitoring subjects

• Groundwater level, temperature and electrical conduction(EC) are measured automatically hourly
• Groundwater quality is analyzed in a laboratory for 19 items and main cation/anion, twice annually

  

Management system for the national Groundwater monitoring network

• Establishment of the monitoring data remote transceiver system
• Improvement of reliability of observed data and minimization of missing data by regular check ups
• Analysis of real-time monitoring data by the national Groundwater monitoring network management system and provision of it through the internet
