Hello Wilbur, 
There is an outfit in Woburn, MA called Analytical Answers (781) 938-0300 that I have used before. 

Excess foam in an aqueous washer, running water only is usually the result of a heavy w/s flux load. This can be exagerated by running mis-print assemblies thru it.
I am down the road from you, call if you would like to discuss. 603-622-2900.
Regards

I am looking for a test lab in the New England area that can test for residue
left on a PCB after completing reflow. We have some of our product that causes
excessive foaming in our aqueous cleaner, and it appears to be excess solder
paste. Need to have these particular boards evaluated to determine if there
actually is excess paste or some other deposit causing this foam problem.
