This scan is a great option for those who are concerned about the quality of their water and/or soil. A small soil sample (at least 2 tablespoons) can be collected from your yard or garden and placed in a ziplock bag. For the water sample, simply soak a cotton ball in your tap water and place it in a separate ziplock bag. The Environmental Toxicity Scan will test for resonating chemicals, heavy metals, and microbes. Some of the toxins we scan for include pesticides & herbicides, lead, arsenic, mercury, and aluminum.
