Background information Summerhill Woods Development Area
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.
