Waste Water Pollution zoning of sensitive coastal-marine areas with an environmental protection approach (Study area: Boujagh International Park and International Wetland)

Sensitive coastal areas are one of the most valuable habitats in the world. The purpose of this study is to zoning of wastewater pollution in Boujagh International Wetland. This research has been done by field method. At first, in order to facilitate the research work, using the networking technique, the whole study area was divided into 33 cells or 500 hectare assessment units (2.2 × 2.2 km networks). Then each criterion was quantified through scoring method (weighing). Quantifying the criteria was done by numeral weighing with restricted domains. Scoring criterion was done in six-step domains from at least 0 to at least 5. The ArcView software was used to draw maps. The research findings indicate that the study area is ecologically sensitive. Of course, the degree of ecological sensitivities varies in different places. The results show that only 3 parameters of nitrite (1.2 mg/l), Potassium (8.1 mg/l) and Co (0.8 μg/l) are in the standard range and the rest of the measured parameters are higher than the allowable limit. Also, the amount of TDS (450 mg/l) and nitrate (0.9 mg/l) was evaluated as average compared to the standard. In order to control the entry of sewage pollution into the wetland and its surrounding votes, it is necessary to take legal and administrative measures immediately.
