Ⅳ. Results
1. In situ tracer (SF₆) measurement system for groundwater contaminant(1-3 years)
- Development for tracer (SF₆) measurement system which is easy to carry, install and has high detection capability. The system configuration is divided into modules such as extraction, analysis, and gas supply unit, and it is easy to assemble and connect the modules in the form of a portable case [Manufacture of prototypes].
- The portable gas chromatograph detector (Electro Capture Detector for SF₆) has been developed (1) to reduce the size of the existing SF6 measurement system (GC-ECD) to about 1/2 size (size and weight) (2) to have a
detection capability ( "detection limit" 10 ppb vs. 10 ppt ) that is about 1000 times higher than that of the existing
SF₆ leak detector [Patent application; 10-2016-0028394].
- Establishment of technologies to optimize the existing laboratory tracer measurement system: Development of concentration / extraction system for detection of ultra-low SF₆ concentration [Patent registration;10-1721387].
- Development of portable and laboratory measuring systems integrated operation modules: Achievement for gas analysis system [Publication; Atmospheric Environment, 2016.06] [Patent application; 10‐2016‐ 0182846].

2. Pollutant tracking technique into groundwater (2-3 years)
- Site selection and basic investigation for the application of the tracer measurement system: In cooperation with the research team of Professor Lee Kang-geun (Seoul National University), the system was installed in a groundwater well selected within an existing operational area (Chungbuk province, Kangwon Wonju).
- Trial experiment for small scale and short-term groundwater tracer measurement: Performed single-well push-pull tracer test using SF₆ for one or two days. Investigate the groundwater velocity and effective porosity [Establishment of groundwater monitoring technique using SF₆ and the successful application results].
- The groundwater tracer measurement test for long term and broad scales: Long-term (about 4 months) monitoring of tracer migration in the groundwater samples after tracer injection [SF₆ was used for groundwater tracer and the excellence of SF₆ performance was verified.]
- Five publications [Geophysical Research Letters, 2016.04; 2016.05],[Limnology and Oceanography, 2016.07], [Algae, 2016.12], [Wetlands,2017.04]

3. Application protocol for groundwater contamination monitoring system(3 year)
- Establishment of application protocol for groundwater contamination monitoring technology through tracer test: Development of groundwater tracer system and method capable of calculating groundwater velocity and effective porosity using SF₆ [Patent registration; 10-1729900]
