摘要：To analyze the impact of heavy metals on well and soil water quality from the HolcimePlant Region, we studied the physicochemical parameters (pH, electrical conductivity,Organic matter, chlorides, sodium, potassium, nitrates, ammonium, sulphates) as well asthe evaluation of the degree of metal contamination (iron, zinc, chromium, copper andlead) present in the samples. The analyses carried out revealed low levels of organicmatter (MO: max = 1.4 mg / l and mineral matter (conductivity: max = 770 ms / cm).)Analysis of waters of wells and soil showed that grades In NO3- present an averageconcentration of less than 40 mg / l with temporal variations of remarkable amplitude (inaccordance with the standards suggested by the World Health Organization and theMoroccan standards). The average chloride contents do not exceed 783 mg / l (suggestedby Moroccan standard). As for nitrous nitrogen, the recorded values showed very lowcontents and were found lower than the Moroccan standards (0.1 mg.l). Concerning theheavy metals, the examined results showed a significant increase in the concentration oflead in the seven wells, in particular well No. 1 (9.95 μg / l), and an elevation in iron andzinc concentration in the seven wells. The copper and chromium contents were relativelylow. In general, the concentrations of these metals at the level of the different sampleswere found lower than the Moroccan standards (NM 03.7.001, March 2006). In the caseof soil analyses, the results showed a high concentration of iron in the seven soillocations, the contents of zinc, chromium and copper remained low, though the leadcontents were considerably low.
