Groundwater, Air, & Soil Testing in Markham

Environmental due diligence processes, such as Phase II Environmental Site Assessments, often require that the soil, groundwater and air at a property be analyzed for potentially harmful contaminants. This is why we offer groundwater testing in Markham.


Phase II Environmental Site Assessments mean a completely focused drive to accumulate important property data that includes:

* Overground and underground sampling of groundwater and soil that includes laboratory tests
* Surface and subsurface sample collection for ACM, PCB and or geophysical surveys
* Noise and radiation measurement
* Citing relevant models or environmental state to gauge the spread of any contamination

What Do We Know About Groundwater Testing?

The treatment of well-water requires a number of assessments to understand the state of the water that can vary due to numerous human and natural causes. pH levels can be different in a location courtesy to geological factors that may have a direct effect on mineral levels. These minerals can range from calcium to chloride to arsenic.

Contamination caused by human actions happen in the form of chlorine or pesticides; this is a major threat to a healthy ecosystem.

Apart from the geologic features, a specialist needs to do a keen study of the land to be able to detect groundwater. When he does track it down, he also calculates the depth and quality of the water to record in his notes for the necessary assessments.
