Edgecomb, Maine-based Fluid Imaging Technologies offers a free service for evaluating water samples to identify contaminants. The service counts, determines the size and takes digital pictures of waterborne organic contaminants such as anthrax, cryptosporidium and cyanobacteria, as well as inorganic contaminants. The results of the tests and analysis, including a scatter diagram and a data spreadsheet documenting every particle or cell detected, are provided on a CD. For more information, contact Kent Peterson at (207) 882-1100 or kent@fluidimaging.com.
