Groundwater pollution is a change in the properties of groundwater due to contamination by microbes, chemicals, hazardous substances and other foreign particles. It is a major type of water pollution. The sources of groundwater pollution are either natural (mineral deposits in rocks) or man-made. Natural sources are less harmful compared to hazardous chemicals generated by human activities. Any chemical present on the surface can travel underground and cause groundwater pollution. The seepage of the chemical depends on the chemical type, soil porosity and hydrology.

The main cause of groundwater pollution is poor installation and maintenance. The disposal of household chemicals, such as paint thinner, into system can also cause ground pollution. Some other causes are:

• Overloading the system with a garbage disposal unit.
• Use of septic tank cleaning additives.
• In a limited area too many closely-spaced septic system.

Some prevention technique of groundwater pollution are:

• Avoid dispose of household chemicals into the system.
• Proper installation.
• Inspection and cleaning in every 2 to 4 years, annually if garbage disposal used.
• Avoid hazardous cleaning additives for septic system.
• Develop local septic system codes.
• Public information and education.
