선진 외국에서 먹는물 중 방사성물질의 관리동향에 대한 고찰은 다음과 같다. 미국은 1974년 안전한 음용수법에 규제안을 설정한 후, 30년 이상 개정하여 현재 우라늄 MCL은 30㎍/L, 라돈 AMCL 4,000pCi/L 또는 MCL 300pCi/L, 라듐-226과 라듐-228의 합 5pCi/L로 설정하여 관리하고 있다. 캐나다는 우라늄을 20㎍/L로 잠정적으로 설정하였다. WHO는 2004년 9월 우라늄과 라돈의 가이드라인을 각각 15㎍/L과 100Bq/L로 개정하였다. 선진 외국은 먹는물 중 방사성물질에 대하여 수십년간 연구조사결과를 토대로 수질기준을 정하였고, 지속적으로 개선 및 보완을 하여 관리하고 있음을 알 수 있었다. The radionuclides in drinking water have been regulated in many countries. In USA, the regulation has been revised for over 30 years since radionuclides have been regulated under Safe Drinking Water Act(SDWA) from 1974. Today, USEPA is finalizing maximum contaminant level goal(MCLG) of zero for radionuclides, maximum contaminant level(MCL) and alternative maximum contaminant level(AMCL) of 300pCi/L and 4,000pCi/L for radon respectively, MCLs of 30㎍/L for uranium, and MCLs of 5pCi/L for combined radium 226 and 228. In Canada, Maximum Acceptable Concentration(MAC) value for uranium is 20㎍ /L. WHO revised the guideline value of uranium and radon to 15㎍/L and 100Bq/L in september 2004, respectively. On this survey, it has been found that international regulations for radionuclides in drinking water have been established and improved steadily on the knowledge basis from the past decades` studies.

Twenty organic chemical substances (Table 2) were isolated from untreated wastewater, as well as treated wastewater, collected at 76 companys of 9 industry group located in the basin of Youngsan River. Those organic compounds were analyzed by Gas Chromatography/Mass Spectrometry(GC/MS) and confirmed through comparison with each standard reagents. Phenol, which was not detected in the raw wastewater, was identified in the effluent of treatment facility, indicating that phenol is generated in the course of industrial wastewater treatment in chemistry company.
