The quality of recycled water depends upon the source water and the level of treatment. Generally recycled water will have a higher concentration of dissolved salts than drinking water. Water with high levels of salts can have adverse effects on plant health and appearance; however, most recycled water produced does not have harmful levels of salts for most plants. Irrigation constituents of greatest concern to agricultural crops or ornamental species are chloride, sodium, bicarbonate, boron, and fluoride. Appropriate plant selection and good irrigation management can minimize the potential impacts of the salts or specific ions of concern.
