Abstract: One of the most recurring causes of the presence of aluminum in drinking water is the addition of aluminum salts as a coagulating agent. The use of this adjuvant requires the installation of the particular pH conditions, which if not implemented lead to higher concentrations in the treated waters. The presence of this salt may also indicate poor coagulation conditions, which could impair the final quality of the treated water. The objective of this work is to evaluate the aluminum concentrations in the various surface water treatment works of the Taksebt dam treatment plant (from the inlet of the station to the outlet of the reservoir) by the LCK 301 method. This study showed that the analytical results at the SEEAL laboratory level in the treated waters are pH-related and that these concentrations are below the standard set at (0.2mg/l).
