Chemical Testing Program Sample Clauses

Chemical Testing Program. The scope of work for this project included chemical testing of soil from the boreholes to assist in selection of disposal options for excess soils that may be generated through construction. Accordingly, nine (9) soil samples including one (1) duplicate from the boreholes and one (1) soil sample from a granular stockpile noted on site were submitted for bulk chemical testing. The samples were analyzed for minimum sampling requirements outlined in O. Reg. 406/19 for metals, hydride-forming metals, electrical conductivity (EC), sodium adsorption ratio (SAR), benzene, toluene, ethyl benzene and xylene (collectively ‘BTEX’) and petroleum hydrocarbons (PHC) in accordance with the Ministry of the Environment, Conservation and Parks (MECP) document “Rules For Excess Soil Management And Excess Soil Quality Standards” covered under O.Reg.406/19. One (1) of the samples from the boreholes was also tested for Sulphate to assess potential for sulphate attack on subsurface concrete. In addition, three (3) selected soil samples were subjected to the modified Synthetic Precipitation Leaching Procedure (‘mSPLP’) analysis for metals covered under O.Reg.406/19. Since these samples were submitted to the analytical laboratory under one (1) chain of custody, the Certificate of Analysis cannot be separated to reflect only those samples from the Proposed Building 1 portion of the site. As such, the test results are discussed for all samples submitted for analysis. As of January 1, 2021, the foregoing testing program represents the testing most commonly required by private receiving sites requiring fill for site grading purposes. The soil samples were submitted to an independent laboratory accredited by the Canadian Association for Laboratory Accreditation (CALA). Sample location and analytical data are summarized in the following table. The results of the chemical testing (Certificates of Analysis) are compiled in Appendix B attached. Test results were compared to the applicable tables in the MECP document “Soil Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act” – April 15, 2011 in accordance with O.Reg.153/04 as amended and the “Rules For Excess Soil Management And Excess Soil Quality Standards” in accordance with O.Reg.406/19.
