be evaluated for a range of pollutants and these                  filter out and prevent pollutants from entering our waterways.

     peer reviewer and the results further peer reviewed and
     published in a credible scientific journal. Any potential

     within the published article.

     composition (e.g. soluble vs particulate for nitrogen)
     and the mean concentration of inflow and outflow to
     compare to local and or regional conditions.

 3   Performance evaluation undertaken in dry weather
     conditions or a method to take into account any
     potential leaching of nutrients that may occur in
     the system(s).

 4   Evaluation is conducted using full-scale systems
     with details of treatable flow rates sampled and how
     they correlate to discrete removal efficiencies and
     comparisons to the designed treatable flow rates of
     the device. A comparison should also be made to the
     climatic conditions especially where un-restricted filters
     are used.
