Once you have made a sampling appointment, you will need to do a few things around your home or business to ensure the test produces an accurate result.

• If you have chemicals in your home or business building, look for those described on this page. Check the labels. In particular, look for the chemical trichloroethene, or its synonym, trichloroethylene. If you find a product with this chemical listed on its label, show it to the sampling team when they arrive to place the sampling device.
• Chemicals should be removed at least one week prior to your sampling appointment and should remain outside the home or attached garage for the duration of the sampling event. If the sampling team finds a product that contains a chemical that could interfere with the testing, the appointment will need to be rescheduled.
• Continue to live your life as normal. You can do most of the things you would normally do. You don't need to leave the house and you won't need to take any special precautions.
• Avoid working on hobby projects that use paint, glues or other chemicals. White glue is okay, but avoid glues that are in glass bottles or metal tubes. If you have any of these types of glues, please identify them to the sampling team.
• Gun owners, avoid cleaning your guns insideduring the sampling period and make sure any cloth or brushes used in cleaning are moved and kept outside. Some gun cleaners contain trichloroethene. Cleaning your guns could cause a detection and dirty rags could still emit detectable levels of TCE vapors.
• When the technicians come to place the sampling device, they will ask you a few questions. This will help them determine where best to place the sampling device and find out what items in your home or business may trigger a detection.
• The device will be placed in the lowest livable space in your home. The technicians will work with you to find a suitable place. Make sure the sampling team has access to your basement or lowest livable space.
• While the sampling device will be placed out of the way, try to avoid contact with the device.

The device will remain in your home or business for approximately 26 days. After it is retrieved from the location and sent for analysis at an off-site laboratory, results will be mailed within eight weeks.
