Abstract
Objectives: The work is to evaluate and control the physicochemical quality of the groundwater in the medium Oulmes plate, to protect human health. Methods/Analysis: We have evaluated the quality of seven wells of the area of the plate of oulmes of the Moroccan Atlas during the year 2016; vary by carrying out the analysis for 16 physic-chemical and chemical parameters in the laboratory and “in situ”. These parameters are pH, T, electric conductivity, salinity, potential of oxydoreduction, turbidity, dissolved oxygen, Ca2+,Mg2+,Na+ , K+ , Cl- , SO4 2-, CO32-and HCO3 - . These param- eters are measured by the apparatus Hanna Instruments HI 98280 and Hach 2100 NTU, the anions and cations are measured by the atomic absorption. Findings: Electric conductivity 4110 µS/cm, salinity is worth 1 mg/l, turbidity 9 TNU, dissolved oxygen 6.63 mg/l, potential of oxydoreduction 118.9 mV, he concentration of calcium 300.7 mg/l, the potassium concentration 39.04 mg/l, the magnesium concentration 65.61 mg/l, the sulphate concentration 102.01 mg/l, nitrate concentration 10.34 mg/l, and bicarbonate concentration 1068 mg/l. Indeed, these got results reveal that the degree of pollution exceeds the threshold of the national and international standards of potability. Application: In front of this situation, this requires a control and a treatment to preserve the natural environment. Keywords: Groundwaters, Morocco, Oulmes, Physic-chemistry, Quality

Summary
Water is much more than one simple human need. It represents an essential component to ensure the continuity of the life. The ground waters are all water present in the basement except for boiler feed waters. In Morocco, the ground waters constitute a significant portion of the hydraulic her it age exploited in the country[1]. The ground waters, often geologically protected, age sometimes exposed with pollution agricultural, industrial or urban. The pollution of ground waters represents one of the most worrying aspects and their use at food ends represents a danger to health[2]. The ground waters age traditionally the water resources privileged for drinking water, because safe from pollutants that the surface water[3]
