IV. Results of R&D 1. Survey of Present Situation A. Survey on existing soil and groundwater monitoring network operation - Survey on exiting soil and groundwater monitoring network has been carried out for preparing to build up the national monitoring network using the pollution detection system to be developed by this study. - The results of the survey are as follows：
II. Comparison of water quality monitoring systems between home and foreign countries and review of the real-time communication technology - To review key technologies (especially, the sensor and communication technology) and configuration of each system by surveying water quality monitoring systems those have been developed home and foreign countreis.
III. Present situation of groundwater/soil pollution in the country and analysis of characteristics - Analysis on present situation of groundwater pollution in the country is carried out to select the measuring items with the sensors of groundwater contamination detection system. - As a result, the levels of nitrate nitrogen, chlorine ion and hydrogen ion which are most frequently concerned are determined as fundamental monitoring items. - After survey and analysis of soil pollution in the country, heavy metal and nitrate nitrogen are chosen as monitoring contaminants, and potential of detecting soil pollution with electric property testers is reviewed.
(1) Present situation of groundwater pollution 1) Measurement results (Ministry of Environment, 2008) by groundwater quality monitoring network (2021 locations) - General contaminants : The level order detected is as general bacteria>NO₃-N>coliform count>TCE>Cl . - Specified harmful substance : general bacteria>TCE>Cl >NO₃-N>pH 2) Contaminants excess frequency by national groundwater monitoring network (478 locations) (Ministry of Land, 2008) : pH>Cl >NO₃-N>As
(2) Present situation of soil pollution 1) Result of operation of soil monitoring network (Year 2005~2007) - Survey on 17 items to 1,500 locations over the country is carried out under supervision of Ministry of Environment (Regional Environmental Office) - F, Zn, Ni levels were comparatively high. - Cd, Pb, F levels were seen to have decreasing trend while Hg, As, TPH increasing. - A trace of Cn and BTEX were detected, while Cr6+, organic phosphorus, PCB, phenol, TCE and PCE were detected under limit.
2. Development of integrated pollution monitoring system I. Development of pollution monitoring equipment that can detect various contaminants - Real-time pollution monitoring system consists of: 1) Data collection module, 2) Transmission (communication) module, 3) Center server data management system , and 4) Warning module. 1) Data collection module: Consists of sensor unit (NO₃-N，Cl-, pH, etc.) and data logger which stores collected data. 2) Transmission (communication) module : Transmits the data collected at data logger. 3) Data management system for center server ： Consists of data receiving unit which receives SMS data from transmission module and database for storage and management of data. 4) Alarm module : When the specified range for the contaminants set at the data management system is exceeded, alarm is send to administrator.
II. Development will minimize energy consumption in system operation.
III. Abandoned wells reuse system will be developed for building up economical monitoring network. (1) Development of simple abandoned wells working system using flubber - To work with abandoned wells with simple devices to use them for monitoring wells by designing a "Simple device using flubber". - Designed simple device adopts simple sealing member with flubber which can expect prevention wasting of resource by making new tube wells.
(2) Development of reusable wells working system - Abandoned well working system is designed to maintain water quality inside wells and protect surrounding aquifer. - Designed abandoned well working system is mounted directly on tube wells to use abandoned well as monitoring well and wasting of resource due to making a new well is prevented.
IV. Construction of integrated real-time monitoring system - Developed integrated real-time monitoring system has a management center where integrated control, monitoring and management of field groundwater monitoring is available. - Storage and management of various data with database application program with MySQL DBA integrated is available. - Configuration incorporates server computer and stability and reliability of system is secured.
3. Development of pollution monitoring network and application in field/evaluation I. Application in connection with existing national monitoring system and long-term operation. - A national groundwater monitoring network area was chosen to compare the data obtained at national groundwater monitoring network and remote detection data of the system developed. - Reliability of the remote detection data of the system developed is confirmed by above method.
II. Application to pilot pollution concerned areas and improvement of equipment. - For the field test areas for pollution sensor performance evaluation by contaminants, groundwater pollution and trends analysis is performed and OO area where duat ion level is detected higher than standard level and the areas where groundwater purification and soil remediation work is in progress due to oil pollution are chosen as pilot areas.
4. Performance improvement and commercial use of the system developed I. Comparison and verification of field measurement and remote monitoring - By long-term stability evaluation of pollution sensor, it’s confirmed that there is nearly no difference between the data collected from field sensors and that gained by sampling water quality analysis by specialized institution considering the time period through to analysis in lab.
II. Equipment/system beta test, performance improvement and manual draft - In this study, the data transmission module, alarm module and integrated manager operating programs of the system developed are improved and the functions upgraded for mass production and commercialization. - The field data collection system, data communication with manager PC programs, remote control, real-time monitoring screen configuration and presentation have been seen normal in operation. - Installation and maintenance manual for the system developed and multiple detection sensors is drafted.
