Water Quality Series Capturing and Recycling Irrigation Runoff as a Pollution Prevention Measure Shanda K. Wilson, Water Quality Assistant Sharon von Broembsen, Extension Plant Pathologist T he need for increased control over water availability and water quality while meeting environmental objectives has led many ornamental nurseries to examine the potential of recycling irrigation runoff as a solution. In certain regions, the main concern may be a lack of quality water, while in other regions, it may be protection of water supplies.
Nurseries are increasingly aware of the effect effluent can have on the environment.
Runoff from nurseries may contain nutrients, pesticides, and herbicides that can have an adverse impact on ecosystems. Increases in nutrients, such as phosphorus, can lead to algal blooms and eutrophication of water bodies, while pesticides and herbicides can disturb biotic communities. Capturing and recycling irrigation runoff can eliminate pollution of local water supplies by nurseries. Water availability varies from region to region. For example, in some parts of Texas, water is a limited commodity for growers.
