Resources / Proposal of environmental accounting housekeeping (EAH) books of domestic wastewater based on water pollutant loads per capita: a case study of Sanbanze Tidal Coastal Zone, Tokyo Bay

Summary

Domestic wastewater contributes much to water pollution in enclosed coastal zones, especially close to urban areas in the developed countries. Wastewater treatment plants are sometimes considered as pollutant sources. Therefore, scientific and quantitative information dissemination for citizens would be necessary in regards to domestic wastewater. This paper proposes a measure of dissemination and environmental education in the field of water pollution, which makes relations between water pollution problems of an enclosed coastal zone, Sanbanze tidal coastal zone, Tokyo Bay, and municipal lives. Firstly, pollutant loads analysis was conducted based on publicly available data, and pollutant loads per capita was calculated for the Ebigawa River drainage area. Secondly, based on the calculation results, basic concepts and examples of the format of environmental accounting housekeeping (EAH) books of domestic wastewater prepared depending on its treatment methods are proposed.
