This study focuses on the amount of chemical properties and microbiology (T.D.S ,T.H,MPN) into the water provided by the environmental health from the private wells Al-Dlail laboratories in a Zarqa Governorate. The research problem focuses on the chemical properties and microbiology (T.D.S, T.H, MPN) of the amount of the water provided by the environmental health of the private wells of Al-Dlail laboratories in a Zarqa Governorate. The research object was to develop the necessary treatments for reducing the presence of unauthorized descent from T.D.S, T.H and MPN.The analytical research methodology was adopted for the case study analysis to achieve the purpose of this research which was to develop necessary treatments to reduce the presence of unauthorized descent from T.D.S, T.H and MPN. To achieve the study objectives, the study uses (Minitab). Based on the statistical analysis, the main results are:The Control Limits for the Total Dissolved Solid (T.D.S) and the Total Hardness (T.H) are within acceptable limits In the Control Limits for the Most Probable Number (MPN), some readings are beyond the extent of control. Also, there are two samples (15,16) that breach the specification and the bacterium Bacillus colon(MPN) limits, which means exceeding the allowed percentage of the limit.The researcher concluded that the Control Limits for the Total Dissolved Solid (T.D.S) are within acceptable limits and the Control Limits for the Total Hardness (T.H) are within acceptable limits. The researcher recommends that the international standard must be adopted in water treatment.
