Evaluation de la conformité de l’eau destinée à l’arrosage des espaces vert dans la région de Ain Témouchent

Abstract

In the municipality of Aïn Témouchent, the irrigation of urban green spaces relies mainly on groundwater (wells) and tap water. The quality of irrigation water is a key factor for plant health and soil sustainability. This study aims to assess the quality of two water sources used for irrigating the Lalla Khadidja Garden, which is managed by the local municipality (APC). Samples were taken from a well and a tap water point, and subjected to both physico-chemical and microbiological analyses. The results were compared against Algerian and international standards. The analyses revealed that both water types are microbiologically safe. From a physico- chemical perspective, tap water was found to be generally suitable for irrigation. However, the well water contained elevated levels of salinity-related elements, which could impact soil fertility if used continuously over time. This research highlights the importance of regular monitoring of irrigation water quality in urban areas to ensure optimal plant development and long-term soil health.
