Subject: Re: Fwd: McIntosh Run, Spryfield- "HRM's-funded' very recent sampling work , as reported to HRM Council as an Info Item on September 17, 2002 and , related aspects
Dear Mr. Mandaville:
Thanks for your note of Sept. 23, 2002 (reproduced below) regarding recent sampling work done in McIntosh Run, in which you point out the inadequacy of the phosphorus data for assessing trophic status of surface waters, and the lack of biological trophic data. The intent of this sampling program was to test for sewage leaks or overflows into the McIntosh Run system from municipal sewer pipes, rather than to assess trophic status. As such, the focus was concentrated on bacteriological parameters.
However, as you have pointed out, if phosphorus data is to be collected for natural surface waters, then analysis methods of adquate sensitivity should be employed. As a result of your suggestion, appropriate HRM staff will be notified to ensure that, when HRM contracts water sampling work which includes phosphorus, the appropriate high-sensitivity (1 microgram/liter detection limit) methodology is specified.
