Physical and chemical parameters of groundwater area agricultural Sidi Abdelrrazak (province of Khemisset)

The sidi abdelrazzak zone (province of khemisset) is an agricultural zone,whose population supplies water starting from water of well. this even underground water is vulnerable to agricultural,industrial pollution from where health risks in the area thus .this study is important and will be thus based on the analysis of the physicochemical parameters of 20 wells and 2 sources and of the targisst river .the results revealed that the tagrisst river shows a certain hydraulogical and chemical stability. on the other hand the wells testify to a variable and notable presence of an organic load related to the productivity of these wells by the development of phytoplankton or the zooplankton. for nitrates the analysis allowed us to raise an appreciable presence,particularly on the level of p13 (29 mg/l) in relation to the productivity recorded in these wells (presence of organic matter),this study requires a follow-up of the quality of ground waters by spreading out the field of study to the neighbouring rural communes in order to make sure of this quality for demolished medical population.
