Soil can be over-irrigated due to poor distribution uniformity or management wastes water, chemicals, and may lead to water pollution. Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring watertable control by some form of subsurface land drainage .

In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
Improving soil drainage is a balancing act requiring consideration of soil composition and compaction, and may take a number of approaches to improve.
Sources of water pollution are either point sources or non-point sources. [34] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant or an oil spill.
