| Research Abstract |
A huge illegal industrial waste dumping site was appeared between Aomori and Iwate. Estimating present situation of water quality, development of decreasing method of harmful impact on farm production and environment was performed. Monitoring results showed bromide was detected relatively high concentration in solutions highly influenced by industrial waste. Remediation activities of the site reduced concentration of it. Bromate in irrigation water indicated inhibitions for growth of crop such as komatsuna from pot cultivation experiments. Dichloromethane (DCM) in groundwater of the site was higher than 100 mg/L. Batch experiments denoted DCM in solution was removed and decomposed by high voltage pulsed discharge in water.
