Contaminated Soils: 3 Reasons to Have a Soil Test Done

Whether it be chemicals, heavy metals or organic matter, the presence of contaminants in soil is rarely good news. However, ignoring the problem can have serious consequences. The question then is: why should you have a soil test carried out?

Performing a soil test: 3 reasons why you should do it

1) Confirm or dispel the presence of contaminants

Basically, a soil study confirms or disproves the presence of contaminants in the soil and identifies its nature. Generally, the pollutants that are identified are:

  • chemicals (such as pesticides);
  • organic matter;
  • heavy metals;
  • hydrocarbons.

For example, the main contaminants found in residential areas include coal deposits, fuel oil, fire ash, industrial embankments and waste materials. Unfortunately, their presence is a reflection of another era, when the regulations governing the management of their residues were not very strict. In some cases, faulty equipment or an accidental spill may also be implicated.

Of course, confirming the presence of contaminants in the soil allows the process of decontaminating and rehabilitating the land as quickly as possible. In doing so, this tends to limit the impact of contaminants on the environment and avoid long-term damage.

While this does not call into question the importance of having a soil analysis done, some Canadian provinces have their own directory of contaminated land.

In Quebec, the Ministry of Environment and the Fight against Climate Change makes available to the public information brought to its attention concerning contaminated land on its territory. To access it, click here.

In Ontario, you can find documentation about contaminated lands and brownfields here.

In Nova Scotia, there is a special section on the government's website here

Alberta has the Environmental site assessment repository here.

2) Being able to get a mortgage

Thinking of building your future home? To be able to make this large-scale project a reality, you will first need to determine its location and therefore identify a land lot of sufficient size to meet your acreage needs. However, keep in mind that many other factors need to be considered before making a definitive decision on a particular field.

Among these is a very important element: the presence of healthy soil. Not only is its presence essential to ensure the sustainability of the building that will be built on the ground, but it is also a legal obligation.

Indeed, your financial institution may ask for irrefutable proof that your land is not contaminated before you can be granted a mortgage. In this regard, it should be noted that even in the context of a sale without a legal guarantee, an environmental assessment may be required to eliminate the possibility that contaminants may be present in the soil.

Moreover, this precaution ensures the viability of the investment and avoids the financial problems that could arise from construction on contaminated land. It should be noted that the test that is required will be phase 1, which is the one used to identify potential or actual risks relating to the presence of contaminants. Finally, it should be noted that the test is valid for 5 years. Therefore, if such an assessment was done less than five years ago, it is still valid.

3) Avoid buying a home with contaminated land

As we mentioned in the previous point, conducting a soil test can be an obligation that you will have to pay if you want to buy land. Thereby, this requirement will also apply to a property already built.

In this context, it should be noted that buying a house without regard for soil conditions can cause a very large number of problems if one or more contaminants are found in the soil. This will result in a long-running battle between buyers and sellers to avoid having to pay the costs required for soil decontamination.

Buyers will then have to prove that there is a hidden defect and the sellers will have to prove the opposite. Besides, the steps required with insurers to obtain compensation can be tedious and not always conclusive.

Once again, you should not believe that selling without a legal guarantee will protect you from lawsuits. Indeed, a prosecution motivated by the discovery of what could be considered in court as a hidden defect cannot be ruled out.

It is therefore intending to avoid all the problems caused by the presence of contaminated soil that a soil test must be carried out. After all, as the saying goes: better safe than sorry!
