    ethanol Eight sites on the East Branch in the Avondale area were sampled in October 2005 by Avondale High School student Dylan Kee under the direction of Stroud Water Research Center Data was collected and processed in comparable way to other Stream Watch data with the exception of two composite samples instead of four individual samples In addition Trout Run Site 25 a tributary that joins the East Branch in Avondale was sampled a single time in March 2005 In the laboratory a microscope was used to remove 200 organisms from detritus material and these individuals were identified usually to family except in 1991 1993 when many taxa were identified to order counted and recorded In years when samples contained many individuals only a portion of each sample e g 50 was processed Sampling procedures were designed and described in a matter that volunteers with minimal training could collect and process the samples These protocols are available by contacting the education department at Stroud Water Research Center Water chemistry was examined in 1994 1997 2003 2005 and 2008 i e 8 of the 15 years Nitrate ammonium and soluble reactive phosphorus were measured in all 8 years but other variables were sampled less often Schedule indicating which water chemistry variables were measured Year Nitrate Ammonium Total Phosphorus SRP Sulfate Alkalinity pH Conductivity Dissolved Organic Carbon 1994 X X X X X 1995 X X X 1996 X X X X X X X 1997 X X X X X X 2003 X X X X X X X X 2004 X X X X X X X X 2005 X X X X X X X X 2008 X X X X X X X X Land Use Sampling sites were located with a handheld Garmin 60CS GPS unit and

    richness From 1991 to 1993 macroinvertebrates were in part only identified to order because volunteers were still learning identification skills Besides density of certain macroinvertebrate groups water quality conditions can also be described by various metrics that are commonly used in water quality monitoring programs Metrics take in to account diversity richness and or composition percentages of certain macroinvertebrate groups Many metrics can be combined to create an index e g Macroinvertebrate Aggregated Index for Streams MAIS a single value that rates water quality for that site Density Epeorus mayfly larvae The quantitative sampling method allowed macroinvertebrate counts to be expressed as a density e g individuals m 2 that was used to compare across sites and years We examined densities of pollution sensitive taxa e g many Ephemeroptera mayflies Plecoptera stoneflies Trichoptera caddisflies and pollution tolerant taxa e g many Diptera true flies Odonata dragonflies damselflies Coleoptera beetles In response to moderate exposure to pollution a decrease in density of pollution sensitive taxa accompanied by an increase in density of pollution tolerant taxa would be predicted Densities of Ephemeroptera Plecoptera and Trichoptera EPT are commonly pooled together and analyzed as a group to assess changes in water habitat quality in streams and rivers Species in this group are generally more pollution sensitive than other taxa thus a decrease in EPT density would be predicted in response to moderate exposure to pollution All density data were natural logarithm transformed a standard procedure to correct for the clumped spatial dispersion of invertebrate populations in rivers MAIS Index To classify stream condition using the macroinvertebrate data we calculated a Macroinvertebrate Aggregated Index for Streams MAIS that uses family level identification that integrates various types of information into a single number that can be used to compare streams It summarizes the values of
