This project is trying to investigate water contamination after use in ponds. For this aquaculture status, physical and chemical water properties, microbial pollutants and heavy metals levels in the some of trout ponds effluent in East Azerbaijan province were evaluated in 2007 to 2009. The information of groundwater and climate conditions in ten years, Drilling and wells piezometric Information, in local wells are reviewed.According to data obtained from analysis of water samples in the output pools range studied concentrations(term mg/l) some parameters are as follows:(BOD: 1.9-3.2),(COD: 3.4-34.1),(TSS: 26.6-42.7),(N-NO2:0.003-.136),(P-Po4:0.0170.067),(pH:7.75-8.28).Electrical conductivity(500 ±2 to 1129±144 term µm/cm) in the effluent ponds . Based on the results of we can say that between input and effluent ponds in the review of all factors as chlorine, sulfate, sodium, potassium, total nitrogen, soluble phosphorus, total phosphorus, calcium, total hardness, magnesium, alkalinity and silica significant changes not be observed. Review of water analysis data to some factors(such as:water temperature,EC,pH,NO2,CO2,HCO3,CO3,DO,COD,BOD) And compare this data with the authorities standard confirmed that the All factors mentioned in effluent is allowed now. In terms of microbial contamination and heavy metals ( Zn,Cu,Ca,Pb,Fe,Cr ) is no pollution. Appropriate strategies for removing suspended materials must to use.We can use Watershed Management solutions to inject output water to the underground table. Should be noted status change (eg change in flow rate, an unusual increase in temperature, fish density increasing, reducing food quality, lack of appropriate management actions and ...) may reduce the effluent quality and the ability of injection water underground to lose . In this case, measures must be for wastewater treatment and improve the quality ponder.Pages
