Jenn, I work at an environmental testing lab. Yep, that's my new full time job. I'm a part time paint queen at Lowe's now
. If you like, I can check the cost of a test. We ship the bottles and instructions directly to you, you send them back and we do the rest. Let me know if you're interested - don't know why I didn't think of that before - probably because of the sleep depravation(2 jobs = 60-75 hrs/week, YIKES). We are Benchmark Analytics if you want to check it out online.
