Caption:  The Chart Table "wq_pesticides_sheep_mbpc_1997_chart.db" was derived from the Source Table "wq_pesticides_sheep_mbpc_1997_source.db." It contains a summary of the results of pesticide monitoring in surface water samples taken in seven of Maine's salmon-bearing rivers and their tributaries in late September 1997 by the Maine Board of Pesticides Control (MBCP). Samples were analyzed for 33 pesticide chemicals and degradation (metabolic breakdown) products. Hexazinone, the only chemical detected, was present in 19 (29.4%) of the 64 samples collected. Data are from Chizmas (1999). See Info Links for more information and a link to the Chizmas (1999) document. A key to column headings: Shortname = A shortname used for labelling, Water_Body = The river or brook sampled; Sampled_Sites = The total number of site sampled in the Water_Body, Sites_Detect_Num = The number of sites sampled in the Water_Body where Hexazinone was detected, Sites_NoDetect_Num = The number of sites sampled in the Water_Body where Hexazinone was not detected, Minimum_ppb = Minimum Hexazinone concentration measured in parts per billion (left blank for sites with no Hexazinone detected), Maximum_ppb = Maximum Hexazinone concentration measured in parts per billion (left blank for sites with no Hexazinone detected).

 50 rows of a possible 64 have been displayed.
