Overview

Randomized trial assesses irrigation suitability based on water quality indices, indicating urgent water management needs in Algeria.

Key Points

  • The study aims to integrate water quality indices with multivariate analysis to assess surface water suitability for irrigation in semi-arid Algeria.
  • Monthly water samples were collected from seven monitoring stations from March 2023 to February 2024, totaling 84 measurements.
  • Surface water quality was assessed using a water quality index (WQI) and multivariate statistics.
  • Spatial analysis identified contamination hotspots and key pollution drivers.
  • Station S4 was identified as a critical contamination hotspot with electrical conductivity at 7515 μS/cm, sodium concentrations exceeding 960 mg/L, and high sodicity values.
  • Nitrate and phosphate levels were elevated at 73.63 mg/L and 278.26 mg/L, respectively, indicating pollution from fertilizer use and wastewater.
  • The study highlights the need for improved irrigation practices and sustainable water management strategies, particularly at contaminated sites.
