The Estimation of the Relationships between Water-Natural Gas Usage and Discharge-Emission Permission by Using Binary Logistic Model for the Industrial Establishments

The Thrace region is one of the most important agricultural and industrial regions in Turkey with its plain, deep and productive soil structure. The most important problem is industrial based water and air pollution in this region. In this study, 90 out of 541 establishments that use industrial water in the region were studied representing approximately 17% of the total population. The relationship between water-natural gas usage and discharge-emission permission is estimated by using the binary logistic model. In addition to the economic and social benefits, there are also economic and social losses due to environmental pollution because of the rapid industrialization in the Thrace Region. For example; the rice producers that use Ergene River for irrigation purposes lose efficiency and quality in various levels due to water pollution. According to the research results, an increase in wastewater is a factor that decreases the probability of obtaining discharge permission. Moreover, excessive use of underground water results in decreases in static and dynamic water levels in the region. Because of this result, it is more advantageous for sustainable water management to be directed to the sectors that do not use water for industrial purposes instead of the sectors that use water in their processes.
