Air/Vapour Intrusion Investigation Evaluation

Although a fairly new area of environmental science and engineering in some jurisdictions, Dragun has been involved with projects involving vapour intrusion for over a decade. Dragun recognizes that the vapour intrusion pathway can be significant and has the potential to cause adverse effects. Our team of experienced associates has worked on numerous projects with vastly diverse conditions. Using good science, we have been able to put vapour intrusion into perspective and allow clients to make informed decisions regarding assessment and remediation efforts.

In fact, Dragun’s senior staff has written articles, conducted seminars, and provided field demonstrations on the science of vapour intrusion, so our clients know the best course of action when faced with a vapour issue.

Indoor Air/Vapour Intrusion Investigation Evaluation Services Include:

• Vapour intrusion investigation, sub-slab sampling
• Peer review
• Review of building structures/HVAC systems
• Regulatory negotiations

Environmental Permitting

Whether you are building a new facility, adding a new operation at an existing facility, or are modifying existing operations, you may need an environmental approval from the Ontario Ministry of Environment, Conservation and Parks.

An Environmental Compliance Approval (ECA) is a permission that allows businesses to operate their facility or site with environmental controls that protect human health and the natural environment.  Changes in your operations may require an amendment to your ECA.

For more information about ECAs, see Ontario’s ECA page.

Dragun Corporation can also assist you with a water withdrawal permit. This may require a Permit to Take Water (PTTW), or in some cases, you can complete an Environmental Activity and Sector Registry (EASR).  See our short video, Permit to Take Water.

For more information about environmental compliance, see our Environmental Compliance Tips and Insights Page.

Water Supply and Water Management

Questions regarding the availability of a clean and plentiful groundwater supply must be addressed when developing a site that does not have access to a public water supply. Our senior team of hydrogeologists will deliver a thorough assessment of groundwater conditions as well as recommendations to maintain a reliable water supply. Whether it’s for a new residential development, a farming operation, or a manufacturing facility, if you depend on groundwater, you need the Dragun method of critical assessment.

Water Supply and Water Management Services Include:

• Peer review of existing data
• Water well record search
• Aquifer tests
• Hydrogeological assessment/investigation
• Permit to take water
• Regulatory negotiations
• Report preparation
