Environmental Objectives

• Protection of surface waters
• Protection of groundwater
• Protection of soil integrity / structure

Possible Environmental Impacts

• Nutrient accumulation in soils
• Odour from wet weather storage or excessive applications of inadequately treated effluent
• Surface runoff resulting from over-application, irrigation during rain or poor site
• Impacts on groundwater underlying the irrigation site
• Salinity issues in vulnerable soils with inadequate leaching
• Soil structural damage
