Abstract |
A survey of Volatile Organic Compounds(VOCs) was conducted in the Kangnung City raw water, treated water and groundwater from Mar. 1994 to Dec. 1994. Four VOCs. 1,1,1- trichloroethane, carbon tetrachloride, trichloroethylene and tetrachloroethylene, were detected below detection limit level. Among those, 1,1,1-trichloroethane, carbon tetrachloride and trichloroethylene were detected at trace and frequently. Trichloroethylene was contaminated in the highest level among detected four VOCs. The mean concentrations of trichloroethylene were 1.15㎍/ℓ of the raw water, 3.30㎍/ℓ of the treated water and 0.47㎍/ℓ of the groundwater. respectively. The concentration levels of the VOCs from the raw water and the treated water were increased from winter to summer, while this trend cannot be found in groundwater. |
