Additional Information

Purpose

Groundwater that contains a substance at concentrations above the applicable numerical water standard at a site but below the local background concentration for that substance, as determined under this technical bulletin or Protocol 9 – Determining Background Groundwater Quality (Protocol 9), would not be considered contaminated under Section 11 (3) of the Contaminated Sites Regulation (CSR). Similarly, groundwater that has been remediated for a substance to concentrations above the applicable numerical water standard for the site but below the local background concentration for that substance as determined under this technical bulletin or Protocol 9 would be considered satisfactorily remediated under Section 17 (2) (b) of the CSR. The local background concentrations established at these sites can be used in the establishment of local background concentrations as outlined in Protocol 9, which will allow the use of these provisions within the CSR.
