The objective of this study is to assess the impact of the use for irrigation of water containing liquid effluents from a textile industry on the nitrate contamination of Allium schoenoprasum crops via soils. To do this, nitrates were determined in soil, water, and Allium schoenoprasum samples and statistical analyzes were performed. It appears that the nitrate concentrations in the water studied, which are significantly different at the sites studied, are below the WHO standard for the use of water for irrigation. In addition, linear regression analysis showed that nitrate concentrations in soils were not related to watering with wastewater from the textile industry but resulted from the extensive use of nitrogen fertilizers. The analysis in principal component showed that the granulometry and the organic matter of the soil would greatly influence the absorption of nitrates by the plants of Allium schoenoprasum Thus, it would seem the waste water of the textile industry is not responsible for the levels in nitrates contained in Allium schoenoprasum plants.
