The effect of municipal wastewater on soil chemical properties

Abstract. The most important concern of the authorities in reuse of wastewater through artificial recharge of aquifers, drinking water and water used in agricultural exchange or direct use treated wastewater for health expenditures in different regions of the world, experience has resulted in effluent into account as a reliable source of water to supply the cities considered any parts of the world to supply water to cities and centers of population. In this direction the use of methods based on low quality irrigation water such as wastewater is a practical and convenient solution. The waste can be a rich source of minerals and organic be considered in order to the fertile soil. In the present study in order to assess the effects of wastewater, sewage refined Shiraz on soil chemical properties were analyzed in depth measurement. All samples from the middle of each plot at depths of 0–30 and 30–60 centimeter and also tested in a randomized complete block design with 3 replications. The results showed a decrease in acidity, salinity, phosphorus, nitrogen and heavy metals concentration in soil irrigated with waste water in the soil is irrigated with well water.
