Six  major  transboundary  wastewater  streams  in  the  West  Bank  were  monitored  for twenty one trace metals and other chemical content. Stream-wastewater samples were collected for the six streams over four month’s duration from September 2010, to February 2011 to cover dry and wet seasons. Each wastewater stream  was sampled six times from the same location. Results  indicate  that  samples  collected  were  spatially  different  in  quality  for  each  stream reflecting the nature of water use and waste generated and drained from the various locations. Temporarily, samples collected had three trend natures: decreasing, small or no changes, and increasing  from dry (fall) to wet (winter) season. Results are discussed separately relevant to each stream, to  the  monitoring season, to the spatial distribution, and to possible causative factors contributing to stream wastewater quality. A section on the way forward and the future of trace metals in wastewater streams in Palestine is included at the end of the paper.
