Abstract :
AbstractIntroductionDue to inaccurate and irregular development of cities, lack of proper consumption patterns andincreasing growth and production of solid waste and also problems and disorders of solid wastemanagement system, the most logical and most cost-effective method for municipal solid wastedisposal is sanitary landfill. This method is a specific engineering operation which is done by solidwaste disposal with minimal health and environmental risks using daily soil cover, creatingimpenetrable layer on the bottom of Landfill to prevent leakage of Leachate and contamination ofgroundwater, leachate collection system and use of layer of sand to control the methane gas. The areaunder study includes total Semnan city with 2291 km2 area. It is located between geographicalcoordinates 34 degrees, 14 minutes and 36 degrees, 11 minutes of north latitudes and 52 degrees, 46minutes and 54 degrees, 11 minutes of east longitudes. The proposed location for construction ofsanitary landfill of Semnan is 25 acres of land which is located 20 km southeast of Semnan.Material and methodIn this paper environmental impact assessment of municipal solid waste sanitary - Engineering landfillof Semnan city and comparing it with not to execute alternative (current landfill) by using a fastmatrix has been done and Parameters have been evaluated on the basis of defined criteria.ResultsResults show that adverse effects resulting from construction activities and operation are in low andvery low level and the positive consequences are at low and medium groups. Soil and air pollution arethe most important environmental problems and creating green spaces, employment, increasingincome, satisfaction of local communities, increasing health indicators are the most desirableenvironmental factors of project. According to the results, sanitary landfill of solid waste in Semnan atthe proposed site with regards to high potential design to solve the health problems in accordance withthe reform options in order to protect air and soil and it is evaluated totally as positive action and willbe permitted.
