The RFC Lab has working groups to continually update, improve and expand on our lab testing procedures.  Working groups meet once every two months, and actively discuss new methods or changes to methods through the forum. Changes to our methods are version controlled so that older data can be referenced to the method used at the time.

We are currently looking for experts in each of the focus areas – Soil, Food, and Human Health.  While there is a small commitment, your input will help direct our results for potentially thousands of samples.  While expertise is critical, we also are looking for people who take an active role in the discussions both on the web, and in the meetings.

If you are interested, please go to the forums and introduce yourself, or contact us directly at
