Environmental Compatibility
Synthetic Precipitation Leach Procedure (SPLP)
    - pH of 4.2 and pH 7.0 (modified SPLP)
    - Testing for metals, volatiles, suffactants, base/neutral
       extractables, acid extractables

Rubber Fill Material Results
    - No adverse levels of any constituents have been extracted
      (relative to human exposure and aquatic toxicity)

Synthetic Fibers (nylon, PP, PET)
    - No adverse levels of any constituents have been extracted
      (relative to human exposure and aquatic toxicity)

 *7 of every 10 trenched silt fence installations have no backfill or compaction*
 *4 out of every 10 trenched silt fence installation will experience undermining*
 *Only 1 out of every 4 trenched silt fence installations effectively pond water*
