I reached out to the NSF and got this reply:
Mr. XXXX, The performance of the IWS System during the ETV evaluation is available at the EPA ETV web site (http://www.epa.gov/etv/pubs/600r06130.pdf). The system operated quite well during the evaluation for organics (BOD), solids, nitrogen and phosphorus. There really are no standards for decentralized systems for nutrients, but the IWS system performed well, with TN reduction of 83 to 88% and TP reduction of 56 to 76%. As a measure, the requirements for certification for nitrogen reduction under NSF/ANSI Standard 245 is 50% reduction of TN.
I hope this information is helpful. Please let me know if you have any further questions. Best regards. Tom Stevens

I also spoke with with a couple of people there (independent conversations) and both spoke very highly of IWS and RCC (in particular Claude Smith). That was encouraging to hear.
You might want to call over there and see if they describe any new projects that they know about as well.
