 Locations near landfills have a lot of potential for contamination of groundwater, because there is a high potential for contamination with emulsion in these areas. In this study, the quality of physic chemical and carbon-organic materials (TOC) of water wells around landfill of Azad-Shahr city was investigated. To accomplish this purpose, sampling of water from seven deep wells around the landfill site (upstream and downstream of the burial site) was carried out in the spring and summer of 2017. Then, its physicochemical parameters such as Electrical Conductivity (EC), temperature, Potential of Hydrogen (PH), chlorine, Total Dissolved Solids (TDS) and hardness were measured by standard methods. Total Dissolved Solids (TDS) is a quantity of the soluble composed quantity of all inorganic and organic substances present in a liquid in molecular, ionized or micro-granular (colloidal sol) suspended form. Electrical Conductivity (EC) is a computation of the dissolved material in an aqueous solution, which relates to the capability of the material to treatment electrical current through it. PH (Potential of Hydrogen) is a quantity of the acidity of the water or soil depend on its hydrogen ion condensation and is mathematically determined as the negative logarithm of the hydrogen ion condensation. Based on the results of TDS, chlorine, hardness, water content of wells around landfill were 719±21, 62±19, 333±73(mg.l) and electrical conductivity was 1440±120(μ, respectively. Temperature and PH were 19.5±0.5 and 7.1±0.15 and TOC was 238±240 (mg.l), respectively. Also, the results showed that the concentration of physicochemical parameters of water wells around landfill is below the standard level of the drinking water of the country and the concentration of all the quality parameters in lower wells was measured more than high wells. Except for the hardness parameter, there was no significant relationship with other parameters.
