Book Description
Runoff originating from irrigated pastures in the foothills of the Sierra Nevada Mountains, in California, contains different pollutants (such as nutrients, sediment and pathogens) that can have serious environmental impacts in water systems downstream. In addition, dissolved organic carbon (DOC) in runoff can influence drinking water quality by forming trihalomethanes (THM), which are hazardous to human health. The effectiveness of THM reduction in irrigated pasture systems with the use of filter strips and the fate of DOM in these systems have received little attention. In this thesis, I tested the use of filter strips in pastures to help improve the quality of runoff water. The approach tested the retention of pollutants from pasture runoff by grassed filter strips (2 m wide) in retaining loads of pollutants originating from pastures (3 m wide). Grassed strips were an effective pollutant load reduction strategy for phosphorus and Escherichia coli, yet, in the case of nitrate and DOM, reduction efficiency was dependent upon the volume of runoff. There was no improvement in NH4 reductions with the use of filter strips. Overall, filter strips successfully decreased nutrient and pathogen load and irrigation management indicated to be an important factor in filter strip efficiency. Filter strips play an important role in reducing the pollutants in runoff and helping improve runoff water quality in irrigated pastures.
