AnchorageSampleLog.csv This file contains Information about the sites sampled for the Anchorage Water Quality Pilot Study and provides a join field to the “SiteLocations.csv” file, which provides the latitude and longitude for each site included in this data submission. SiteName---Descriptive name of the site. MOAMapNumber---Provides the location of the site on the Municipality of Anchorage Wetland Atlas, available at: http://anchoragestormwater.com/wetlands2008.html SiteLocation---This column provides a join field to the SiteLocations.csv file. NumberSedSamples---The number of sediment samples collected at each site. NumberWaterSamples---The number of water samples collected at each site. The study was designed to examine the effects on water quality of routing storm water into natural and constructed wetlands in the municipality of Anchorage. It was also designed to examine the efficacy of the constructed wetlands at improving water quality prior to discharge into local creeks. Not all wetlands had an inlet or outlet. In cases where they did, both were sampled. A few wetlands had two inlets. In these cases, both were sampled. All sample locations were measured with a handheld GPS unit. The links to the exact sample locations are contained in the “ANC_WQ_STUDY_2009.xlsx” worksheet on the “Sample_Coord” worksheet. WaterSampleLocations---A description of where the water sample locations. DateSampled---The date the samples were collected. SedimentID---The sediment sample ID. This provides a join field for the “AnchorageSediments.csv” file, which contains the lab results. WaterComposite---A sample that composited water from the 4 cardinal directions (N,S,E,W) was taken at each site. This field shows the sample ID for each of these samples. WaterInlet1---In cases where there was an inlet that routed road runoff into the wetland, this sample identified the Inlet sample. In some cases, there were two different inlets. In these cases both were sampled. WaterInlet2---In cases where there was an inlet that routed road runoff into the wetland, this sample identified the Inlet sample. In some cases, there were two different inlets. In these cases both were sampled. WaterOutlet---This sample was taken at the outlet of the wetland or constructed sedimentation pond to a creek. SampledBy---Describes who collected the sample. MP is Margaret Perdue (maragaret_perdue@fws.gov) and MR is Mari Reeves (mari_reeves@fws.gov) SiteType---Prospective wetlands in the Municipality of Anchorage (MOA) were stratified by their type prior to random selection. These sites included reference sites with no direct storm water runoff from roads “reference”, natural wetlands into which the MOA has routed storm water from road runoff, “non-constructed”, and artificial wetlands or storm water retention ponds, which were constructed by MOA to contain and treat storm water runoff “constructed”.
