Nygren Draw — Data for sites SW -N213 (up gradient) and SW -N214 (down gradient) have been <br />complied and are shown on the summary tables below and graphically. Summary tables for <br />indicator parameters are provide below for each site and include data from 2008 to the end of <br />September of 2017 if available. <br />`: .z±i^+;E'9w+:,'{�.#•%s.. 9.G}YM"''•1', r.i^ ne- a't1"' ..7' �a2ly .,:h.i -s v ,....,j+e ` 7.k:&;-. <br />Mean <br />;:" <br />Range. <br />�` ,.moi. <br />Min. <br />�i1'" i. <br />y``� <br />Min at <br />Std <br />Range <br />Max. <br />Min. <br />Max at <br />Min at <br />- <br />xv Mfr. <br />` <br />8.4 <br />{%1 <br />0.2 <br />8.5 ' . <br />8.3 <br />`? <br />5/22/14 <br />Leib.
