Point source water pollution is discharged from a discrete location.
Point source pollutants in groundwater are usually found in a plume that has the highest concentrations of the pollutant nearest the source and diminishing concentrations farther away from the source.
The various types of point source pollutants found in waters are as varied as the types of business, industry, agricultural and urban sources that produce them.
These can include:
In groundwater some of the most persistent point source pollutants in groundwater are volatile organic compounds, which include manufactured and refined toxic substances, non-aqueous phase organic compounds, such as solvents, oils, paint and fuel products.
