Firstly, and more commonly, water quality guidelines are used to assess the fitness for use (FFU) of a given water for a specific purpose. Secondly, water quality guidelines are used to determine the desired composition of water that would pose minimal risk when used for a specific purpose, the so-called Water Quality Requirements (WQR). In this article we will focus on the first of these applications and specifically introduce a newly developed electronic Decision Support System (DSS) that guides the user to assess the fitness for use of a potential irrigation water.en© South African Irrigation InstituteWaterFitness for use (FFU)Water quality requirements (WQR)Decision support system (DSS)Article
