So many have sent me this report. As many of you know I am a Sr Industrial Hygienist and Environmental Specialist. 

I appreciate the robust detail on sampling and chain of custody, but as I said earlier this winter, when advising people not to eat snow, you will find viruses, bacteria, and a wide array of toxicants in fog, rain, and snow.  When using a PCR test, you can find almost anything if you look closely enough. It is difficult to determine what is naturally occurring and what could have been purposefully dispersed because, when sampling (whether grab samples or swipe samples), you must consider the sampling site's surroundings.  Different manufacturing industries and emissions, reported as PM2.5, factor into the results. This is called including background sampling data. For example, how far away was the sampling location from a wastewater treatment facility?
