Busan Becomes the First in the Nation to Establish Real-Time Groundwater Quality and Level Monitoring System

내용

The Busan Metropolitan City, led by Mayor Park Heong-joon, announced that it has become the first in the nation to establish a real-time monitoring system that allows groundwater quality and levels to be checked across 245 auxiliary observation wells in the city.

○ In the long term, data collected through this system will be compiled into a database and used to analyze trends regularly, enabling preemptive responses to changes in water quality and groundwater depletion.

□ With the establishment of this system, the city can now respond quickly to sudden deterioration in groundwater quality or fluctuations in groundwater levels. In particular, changes in groundwater levels can now be tracked in areas with high hot spring water consumption such as Dongnae-gu and Haeundae-gu, and the data will be used to inform policies for the efficient development and utilization of hot springs.

○ In addition, the system allows for immediate detection of anomalies in the auxiliary observation wells, minimizing equipment errors and thereby improving data reliability.

□ Lee Byeong-seok, Director of Busan’s Environmental and Water Policy Office, stated,
“Once groundwater is contaminated or depleted, it takes a long time to recover.
We will do our utmost to make groundwater conservation and management more systematic and ensure its efficient use through this monitoring system.”

※ As of 2023:
– Number of permitted groundwater use sites: 6,400
– Annual usage: 37,647 tons

◈ System Operations and Program Features

Groundwater Management
– Observation data management
– Observation data statistics
– Data printing and graph generation
– Comparison of observation data
– Well status lookup
– Observation station map
– Observation station management

Groundwater Information
– Definition and basics of groundwater
– Public information services
– Domestic and international groundwater trends
– Industry stakeholders
– Preliminary surveys and related data

System Management
– User management

◈ Expected Outcomes
– The system will support the establishment of policies for groundwater use and development by enabling the analysis of collected data to assess groundwater quantity and quality.
– It will enhance data reliability by immediately detecting abnormalities in observation networks and minimizing equipment errors.

System Description:
❖ Data is collected from field sites using wired/wireless communication and the Internet, then compiled in a central database.
❖ Real-time analysis and statistical processing allow for hourly, daily, monthly, and yearly data management by observation station.
