Groundwater Pollution

Groundwater pollution is a very serious problem. Unlike a lot of the pollution on the surface waters, like trash floating in the bay, groundwater pollution is harder to recognize until after illness has occurred.

Groundwater, which is the  water that remains under the ground and is tapped into to provide drinking water for homes is generally polluted by the activities that occur just above it. People are the number one cause of groundwater pollution. Having water samples tested regularly is the only way to be sure that the groundwater is not contaminated. Unfortunately, there are a multitude of potentiol groundwater pollutants that can seriously contaminate drinking water. Most ground water  pollution happens because of improper disposal, use or stotage  of chemicals, pesticides, or substances like car engine oil.

Deicing salts that are used for clearing driveways and pathways can contaminate groundwater. Landfills have been known to cause toxic runoff that infiltrated the groundwaters supply and underground tanks for storing gasoline and diesel for petrol stations can develop minor leaks and seep into the ground.

A groundwater supply that  is directly over a plot filled with animals, such as a farm environment, can be contaminated with the bacteria from aminal waste, The chronic use of chemically based pollutants such as weed killer, insecticides, and antifreeze puts many home groundwater supplies at risk for contamination.


Because there  are so many variables that can lead to groundwater pollution it is vital that the state of groundwater health be tested regularly.

Different causes of groundwater pollution have different warning signs. Sometimes these warning signs can  be found in the water itself while other times it takes awareness of one’s surroundings  to notice a problem. Being aware of potention dangers can help determine a problem should one develop.

When buying or leasing a new property, residents should become familiar with the hazards that are nearby. Is there a landfill in the area or a gas station across the street? Does the property have a septic system? This type of informaton can help residents keep themselves safe from exposure to pollution that can enter groundwater.

The three most common causes of groundwater pollution are septic systems, residential use of pesticides or automobile chemicals, and the use of deicing salts. If deicing salts were to seep into the groundwater supply the water’s  taste would become suspiciously salty. It takes a home test to determine high levels of chloride in the water itself to confirm the suspicions.

Most pesticides and other home use chemicals are either not readily detected in the water or will cause sudden illness in everything that the water is used to sustain. When plant life that is watered with pesticide polluted groundwater the plants tend to become ill and die. Animals that drink from the polluted water also become ill and may die.

If there is a stream or other small body of water on the property or nearby it is likely that the groundwater contaminaton has leached into the surface water and is killing the aquatic plants, fish and other dependant animals. While it usually takes a significant amount of chemical residue create such health hazards, over time some chemicals can accumulate and the property can have much more chemical base contaminants than originally  thought.

Septic system pollution usually shows signs of septic system failure elsewhere. Residents are likely to find that the septic system has backed up and is creating a raw sewage flood somewhere in the yard or the surrounding property.

In most cases groundwater tests are needed to determine the level of bacteria that infiltrated the groundwater. In very rare cases the water might appear to be off color or contain an unwelcome aroma.

 – Think before using any products or substances that might be harmfull to groundwater, even though you think it might not be enough to cause pollution of any sort, the other person might think the same, and at the end everybody is at risk.
