Bottled water companies submit monthly hydrologic data including periodical environmental effects investigation, daily water production capacity, water production, water level, water chemistry (pH, EC, temperature) per hour and strictly manage groundwater by periodical analyses. Thus few problems concerning drawdown due to excess intake of groundwater take place. Nevertheless, bottled water companies are imprinted as a contribution to civil affairs resulted regarding groundwater near the companies. Therefore, a new method is required during water balance analysis in environmental effects evaluation, which should be compatible with the evaluation by hydrologic experts as well more accessible to non-experts. In this study, water level of surface water and recharge rate in subcatchment where water production wells are located were measured and monthly baseflow rates were separated from normal streams. Besides, recharge properties of groundwater and surface water in the same catchment area were estimated using analyses of oxygen and hydrogen isotopes in groundwater (production well), surface water, and rainfall.

This work was initiated to investigate current situation and problems in applying groundwater-related models for various kinds of environmental impact assessment in Korea. and therefore. to enhance appropriate application in the future. This study was carried out with 544 and 16 documents of EIA (Environmental Impact Assessment. Law of Environmental Impact Assessment) and Mineral-Water EIA (“the environmental impact investigation for mineral water developments”; Law of Drinking Water Management). respectively. It was revealed that there were considerably many cases which may cause serious impacts on subsurface environments in EIA. However. none applied groundwater models. Generally, the influences on subsurface system were underestimated or even ignored in EIA. For Mineral-Water EIA. groundwater models wert applied. in general. But. numerous and serious problems were noted: limited number of calibration parameters and parameter types. setting boundary conditions without adequate bases. recharge rates several times higher than precipitation rates. numerically unstable results. etc. Such kinds of misusages seem to be caused by modelers larking in professional knowledges. To solve the problems revealed from this study. more systematic re-education programs are suggested.

This study was performed to compare international analytical methods of bromate and applied to determine bromate in bottled mineral water in Korea. Bromate in bottled mineral water was eluted by 10~50 mM potassium hydroxide (KOH) and determined by ion chromatograph-suppressed conductivity detector (ICCD). Sample was purified with on guard Ba-, Ag- and H-cartridges and $0.2\;{\mu}m$ membrane filter. The method detection limit (MDL) and the limit of quantitation (LOQ) of bromate were 0.1 and $0.5\;{\mu}g/L$, respectively. The calibration curve showed good lineality above 0.9998 in the ranges of the $0.5\sim40\;{\mu}g/L$. Bromate from 33 samples among total 157 bottled mineral water samples was detected in the concentration range of $0.5\sim6.5\;{\mu}g/L$. The detected concentrations were within bottled mineral water quality criteria ($10\;{\mu}g/L$) in Korea.
