In 1980s, environmental pollution of the high-tech-industries, “high-tech-pollution”, was confirmed. One of high-tech-pollution is the environmental pollution by the semiconductor industry. Especially, people watch the underground water pollution with interest. It is polluted by the organic solvents which is usually used for washing in the semiconductor factories.
Firstly, the underground water pollution by the organic solvents was confirmed in “Silicon valley”. So, in 1982, the environment agency of Japan investigated into the underground water and confirmed its pollution by the organic solvents.
But, its investigation did not determine the causal relationship between the underground water pollution and the semiconductor industry.
Therefore, I questionnaired to the local governments which the semicondutor industry located in it's region and asked a question whether the underground water was polluted and how they took antipollution measures. By the questionnaire, I confirmed that the underground water was polluted in the semiconductor industry located area and the local governments did not make effective antipollution measures.
