Summary of Proposed Amendments to Analytical Protocols and Standards
On February 25th, 2011, the Ontario Ministry of the Environment posted a new proposal for amending Reg. 153/04, with a 45-day comment period between February 25th and April 11th of this year. The comment period is over and we are waiting for the MOE to issue a final release. Among revisions identified from the original amending proposal are the following:
- Samples for VOCs, BTEX/F1 petroleum hydrocarbons and 1,4-dioxane (if tested as a VOC) are to follow EPA 5035A collection techniques, eliminating the option for samples to be submitted in jars. This means samples may only be collected using field preservation or hermetic sampling devices. While this is only for sites where a Record of Site Condition will be filed, it will likely become the sampling standard for other situations such as baseline investigations or spill cleanups. Maxxam procedures and costs are in the EPA5035A Technical Bulletin.
Note: Due to poor sensitivity, Maxxam’s position is 1,4-dioxane should be either field preserved with sodium bisulphate or submitted in jars, not field preserved in methanol as the MOE requires in the recently proposed amendments. Our scientists will be addressing this with the MOE.
Hermetic samplers and field preservation kits will be available for demonstration use at Maxxam sample reception points across Ontario.
- Groundwater samples for dissolved mercury must now be field filtered and preserved in an HDPE or glass container with HCl. The MOE has allowed a provision for lab filtration for both dissolved ICP/MS metals and mercury, though this is not stated in Table B of the protocols.
- Changes to F1, F3, and F4 soil standards in Tables 1, 8, and 9 (units ug/g)
- Changes to the following sodium groundwater standards in tables 3, 5, 7 and 9 (units in ug/L)
- Changes to some VOCs, boron, mercury, hexchlorobutadiene and hexchloroethane standards in Tables 4 and 5.
