Some good news . . . and some bad

We have receive the results of tests run on samples taken from the lake on June 17th.  We tested the same five locations, and none contained more than 15  ppb (parts per billion) of triclopyr.  Therefore the “voluntary” restriction on drinking and cooking with water from the lake has been lifted.  Again we remind you that we recommend that you never drink lake water without treatment or filtration.

At the same time we have been informed that, because triclopyr was found at detectable levels at the downstream testing site, we are required to extend the restriction (again, voluntary) on irrigation an additional 1.5 miles downstream. In accordance with the terms of our permit, certified letters have been sent to property owners downstream as far as 621 Barker Road.

[the following is the opinion of the author, who is not an expert]  We believe that the State’s restriction on irrigation is overly broad.  Triclopyr is an effective herbicide for dicots.  It is not toxic to monocots (e.g. grasses) or Gymnosperms (e.g. conifers).  There is no danger from irrigation of lawns.  In addition, the requirement that the concentration of triclopyr be less than one ppb (part per billion) Before the restriction is lifted seems unnecessarily low.  We would welcome some quantitatidata justification.
