Background groundwater concentration values for 27 inorganic parameters collected from specific sites in British Columbia. This data represents the 95th percentile of data collected from all the representative background monitoring wells on an individual site. This data was used to calculate the regional groundwater background concentrations.

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 Protocol 9 – Establishing Local Background Groundwater Concentrations in Groundwater (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 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.
