Independent testing by the Ontario Ministry of the Environment & Climate Change confirms water quality
The Burlington Airpark announced that a second round of groundwater testing, as recommended by the Ontario Ministry of the Environment and Climate Change, has been completed.
The results indicated that the groundwater continues to meet the standards of the Ontario Ministry of the Environment and Climate Change Table 2: Full Depth Generic Site Conditions Standards for Use in a Potable Ground Water Condition, applicable for residential, parkland and institutional property use. Performed by Pinchin Environmental (utilizing an independent, fully accredited laboratory, Maxxam Analytics Inc.), the supplementary testing was conducted between Oct. 31 and Nov. 28, 2014. The original round of groundwater testing was carried out between September 2013 and March 2014.
As with the first round of testing, groundwater in three of the 11 wells in one particular location showed elevated levels of uranium. The first round of testing included soil samples from these wells which showed the level of uranium in the soil (both the fill and native material) was well below the Table 2 standards, leading Pinchin to conclude the elevated levels detected in the groundwater from these three wells did not result from the deposit of fill material at the site, but rather were the result of naturally occurring uranium known to exist in the underlying bedrock formation.
A copy of the supplementary testing report has been provided to the Ontario Ministry of the Environment and Climate Change and will be made available on the Burlington Airpark's website.
