Project Team Organization Budget Thetotalbudgetforthisprojectis$95,000.ThisincludesPCBanalysisbyAXYSAnalyticalServices, conventionalparameteranalysesbySVLAnalytical,fieldsamplingbyGravityEnvironmental,andoversight anddataanalysisbyLimnoTech. Background TheSpokaneRiverwatershedhasexistingPCBmonitoringdata,whichprovideanestimateoftheamountof PCBsenteringtheSpokaneRiverfromcontributingsourceareacategories(e.g.stormwater,WWTPs).Based ontheSpokaneRiverPCBSourceAssessment2004‐2007(Serdaretal,2011),only43%ofthePCBsource loadingtotheriverbetweenStateline(RM96.1)andLongLakeDam(RM33.9)couldbeidentified.Thisis dueinparttotheuncertaintyoftheanalysesandthehighvariabilityinthedata.Theexistingdataindicate thatsourcesofPCBsareverydiffusethroughoutthewatershed,suchthatmoredatawillbeneededto supportdevelopmentofamanagementplanwithtargetedcontrolactions(LimnoTech,2013).Twostudies wereconductedin2014,theConfidenceIntervalTestingandtheSynopticSurvey. Confidence Interval Testing ConfidenceIntervalTestingwasperformedinMay2014toprovideinformationforthe2014sampling program.TheConfidenceIntervalTestingwasperformedbyEcologyasaninitialtasktoconfirmthe appropriatesamplevolumesandfrequencies.Thisinitialsamplingeffortwasdesignedtogenerate 5 Spokane River Quality Assurance Project Plan – Addendum 1 August 11, 2015 informationbothonthetemporalvariabilityofPCBconcentrations,aswellasestimatesofmeasurement uncertaintyforthelowPCBconcentrationsoccurringintheSpokaneRiver. FivesamplingeventswereconductedinMay2014ontheSpokaneRiverattheStateParkParcelatRiverMile 87,locatedbetweenMirabeauandSullivanParks(referredtoastheMirabeauParksite)andthreesampling eventsattheLakeCoeurd’Aleneoutlet.Sampleswerecollectedforbothdiscreteandcompositeanalysesat MirabeauPark,whilediscretesampleswerecollectedattheLakeCoeurd’Aleneoutlet. TheresultsshowedthatPCBconcentrationswereverylowatbothstations,withlabblank‐corrected concentrationsrangingfrom7.7to54pg/lattheLakeCoeurd'AleneOutletand6.2to80pg/latMirabeau Park.Concentrationsobservedintripblanksandlaboratoryblankswereatsimilarlevelstothoseobserved infieldsamples,makingitdifficulttodistinguishanenvironmentalsignalfromthenoiseinlaboratory measurement.Basedontheseresults,itwasdeterminedthatthePCBconcentrationswerepredictedtobe significantlyhigherduringtheAugust2014SynopticSurveythantheywereduringtheMaysampling,dueto muchlowerriverflowsandconsequentlylowerdilutionofweather‐independentexternalPCBsources. Therefore,thedatawouldbesufficienttosupportasemi‐quantitativemassbalanceassessmentandbeable toidentifystreamreacheswhereincrementalloadsleadtoasignificantincreaseinriverconcentrations. 2014 Synoptic Survey The2014SynopticSurveyconsistedofdryweathersamplinginAugust2014,atmultiplelocationsinthe SpokaneRiverupstreamofLakeSpokane.Thesestationsconsistedofriverlocationswithgagingstations, NPDESpermittedsourcesandtheLatah(Hangman)Creekmouth.Multipleriversamplingeventswere conducted(withsomecompositingtoreduceanalyticalcosts)overatwoweeksamplingperiodtoreducethe uncertaintyinloadingestimatescausedbydaytodayvariabilityinconcentrations. TheresultsshowedthattotalPCBconcentrationsaremostlybelow50pg/lfromtheLakeCoeurd’Alene outlettotheBarkerRoadBridge.Concentrationsaregenerallybetween100and200pg/lfromtheTrent AvenueBridgedownstreamtoNineMileDam.Approximatelyonequarterofallsamplesexceedthe Washingtonwaterqualitystandardof170pg/l,whileallofthesamplesexceedthedownstreamSpokane TribeofIndians’waterqualitystandardof1.3pg/l. 2105 Dry Weather Survey Theobjectiveof2015DryWeatherSurveyistocollectthenecessarydatatorepeatthesemi‐quantitative massbalanceassessmentconductedusingthe2014SynopticSurveydata,focusingonthesectionofriver betweenBarkerRoadandtheSpokaneUSGSGage.The2015samplinglocationsarebasedontheresultsof 2014SynopticSurvey,whichshowedthestronglikelihoodofagroundwaterPCBsourcebetweenBarker RoadandtheTrentAvenueBridge,andthepotentialofanadditionalgroundwaterPCBsourcebetweenthe TrentAvenueBridgeandtheSpokaneUSGSgage(LimnoTech,2015).Thein‐streamsamplinglocationshave beenplacedinanarrowerspatialareatofurtheridentifypotentialgroundwatercontributions.

The use and setup of additional optional system components are detailed on other Quick Start Guides. For more detailed information, refer to the User Manual which can be found on the software CD or via Start | All Programs | SonTek Software after installation. What’s in the Case? P Q R S T RTK GPS Components and Accessories RTK Base Station with Tripod Adapter, GPS antenna, rod and mount Tripod Antenna cable for RTK Base Station Radio Antenna for RTK Base Station Battery Packs for RTK Base Station (x2) Battery Recharger for RTK Base Station Important RiverSurveyor Facts The specifications for the two available RiverSurveyor ADP models are below. Only one ADP is provided with each RiverSurveyor system: RiverSurveyor ADP Range Profiling: 0.06 to 5.0 m Depth: 15.0 m S5 OR What does the RiverSurveyor do? Profiling: 0.06 to 30.0 m Depth: 80.0 m M9 A Some important tips on the RiverSurveyor and its use: • The RiverSurveyor requires no calibration. • Data files are stored on the system and not the PC. They must be downloaded from the system. • Discharge calculation is internal, so measurement quality is unaffected by communications losses. B C E D The RiverSurveyor measures velocities in 3-D throughout the water column below the ADP. It combines tracking information (from Bottom-Track or optional GPS) to measure the total discharge across a river section. Assembling the System The following instructions apply to Standard configuration systems using the Serial Power/Communications cable directly connected to the system for communications and power. Make sure that the cable connector is flush with the ADP connector. Tighten the locking sleeve.

The Installation Menu should appear automatically. If not, double click on setup.exe in your CD-ROM drive menu. Install RiverSurveyor Live for PC. Measuring Discharge - Theory The total discharge through a measurement section is computed based on the mean water velocity in the water column and the cross-sectional area. For the purposes of a measurement, the section is broken into three key components: the Start Edge, the Transect and the End Edge. These components are summed together to calculate the total discharge as shown below: Start Edge End Edge Transect RiverSurveyor – Quick Start Guide: Getting started with the RiverSurveyor System Discharge Measurement Facts and Tips Updating and Changing Settings Site selection is an important part of a discharge measurement and can be fundamental in its success. Here are a few quick guidelines to aim for: • Avoid possible obstructions and immediately downstream of bridges, dates and weirs • Flow should be uniform with minimal turbulence • Consider the ADP’s profiling and depth specification (shown on the other side) Key factors when making a discharge measurement: • During the edge measurements, keep the vessel as stationary as possible. • During the transect, maintain a constant vessel speed and direction as is practical. • Ideally, any vessel movement should be slow relative to the flow velocity, and changes in heading should be gradual. These settings are typically specific to the site and should be reviewed prior to starting a measurement. Direct Connection to the System Connect to the system using the Windows software by pressing the Connect button or the Quick Link on the Start page. Connect button Quick Link Select the Serial Port that the ADP is connected to and press Connect The System page (shown to the right) will be displayed showing the system configuration, settings and utility functions. System Settings Enter the depth the vertical beam is below the water surface, Salinity and Magnetic Declination Windows Software Data Collection To collect discharge data using the Windows software: 1. Press the Start button (or F5) to start data collection, but this does not record any data. Instead it allows the data from the system to be viewed to make sure the system is operating correctly. Make sure that all indicators (shown in the top left) are all valid (not red). Position the vessel at the start edge of the transect. 2. Press the Start Edge button (or F5) and collect at least 10 edge samples. The Edge windows will be displayed showing both edges. Keep the vessel as stationary as possible during this time. Input the start edge information into the Edge dialog that pops up and press OK. 3. Press the Start Moving button (or F5) and the Transect window will be displayed. Keep the vessel speed and direction constant as you cross the river. Pre-Measurement Tests It is important to ensure the integrity of the system prior to any measurements and there are a series of tests that should be performed in this process: • Compass Calibration is necessary prior to all measurements and compensates for magnetic fields. In the Utilities section in the software select Compass Calibration. Press the Start button and rotate the ADP through two complete circles while varying pitch and roll. Magnetic Distortion (M) should be below 10. Keep your cell phone away from the system Site Information Enter all relevant information to the site and measurement. Note that more information is better that less. Calibration Score (Q) should be above 3 4. When the vessel reaches the end edge press the End Edge button (or F5). Follow the same instructions as for the Start Edge (Step 2). 5. Press the End Transect button on completion of the end edge. This automatically opens a new data collection window so you can start a new measurement. The system is still running, so if you need to keep making measurements repeat steps 2 to 5 again or press the Abort button (or F8) to stop. 6. On completion of all your measurements, it is recommended to go to the System tab and download all your collected data files.
