Soil Testing​

Testing soil is part of the normal development approval process for all developers. This land was used as an apple orchard over 50 years ago. Arsenic was a common component of insecticides used in fruit orchards until the mid 1950s and, more than 50 years later, residues can still be found in topsoil. Arsenic is also a naturally occurring element in the environment.

The concentrations of arsenic found in topsoil in the Summerhill Woods residential area are all below the Ministry of the Environment's residential land-use standard of 25 parts per million. In accordance with this standard, these levels do not pose a public health and safety concern.​​​
