The cartridgewas firsetlutedwith5 mL of 40% methanol inwater solution.The eluatewas discardedand the SPE column was then elutedwith 100% methanol. A 5 ml portionof methanol was collectedforanalysisby LC/MS/MS. This treatmentresultedinan eight-fold concentrationofthe samples priorto analysis.

In HPLC, an aliquotof extractisinjectedand passed through a liquid-phasechromatographic column. Based on the affinitoyf the analyteforthe stationarpyhase inthe column relafivteo
theliquidmobile phase, the analytiesretainfeodra charactedsfiacmount of time. Following
HPLC separation,ES/MS providesa rapidand accurate means for analyzinga wide range of organic compounds, includingfluorochemicals.Electrosprayisgenerallyoperated at relafively mild temperatures;molecules are ionized,fragmented,and detected. Ions characteristiocf known fluorochemicalsare observed and quantitatedagainststandards.
A Hewlett-PackardHP1 100 HPLC system coupled toa Micromass Ulfima MS/MS was used to analyze the sample extracts.Analysiswas performed using selected reactionmonitoring (SRM). Samples were extractedon 5/18/00and analyzed by MS/MS between 5/20/00 and 5121/00.The HPLC and MS/MS methods used foranalysisand instrumentparameters can be found inattachment D.

Calibration
A 7-pointcalibratiocnurve was analyzed at the beginningpnd end of the analyticaslequence forthe compounds of interestT.he calibratiopnointswere prepared at 0, 25, 50, 100, 250, 500, and 1000 ng/L (ppt)The response of the quantitabonion versus the concentrationwas plottedforeach point. Using linearregressionwith 1/xweighfing,the slope,y-intercepatnd correlatiocnoefficien(tr)and coefficienotf detenninabon(r2)were determined. A calibration curve isacceptableffr> 0.985 (r2> 0.970).
Calibrationstandardsare prepared usingthe same SPE procedure used forsamples.

MONITORING:
MULTI-CITY STUDY
SURFACE WATER
August 2000
As fullydescribedintheMay 4,2000 submittaltoEPA, themulti-citsytudywas designedtoobtainpreliminarydata about dispersioonffluorochemicalisnthe environment,uptake intofoods,and presenceindrinkingwater tounderstand the potentiaslourcesofhuman and environmentalexposuresthatmight resultfrom this typeofdispersionT.he multi-citsytudypaireda cityhavingmanufacturingor commercial use offluorochemicalproductsbased on customer saleswith a citythat doesnot.Initiallsyixcities(,threepairs)are beingexamined. The studymay be expanded depending on furtherresults.
Based on furtherreviewand analysisofinformationpertainingto manufacturingor commercial use offluorochemicalsi,thas been learnedthatfiveofthe sixcity locationfsallintothatcategoryofsupplylocationsT.hus, thesix-citsytudyprogram shouldbe consideredasa broad based environmentalmonitoringprogram only, withouttheabilittyodifferentiastuepplychainfrom non-supplychaincities.
The multi-citsytudywillyieldenvironmentaldistributiodnata aswellas dataon potentiaslourcesof human exposure.The citiewsere selectedtorepresenturban locationwsith variouslevelsoffluorochemicalreleasesand varioustypesof municipalwater supplies.The samples tobe obtained,where possiblei,nclude: urban air,surfacewater column and surfacemicrolayer,sediment,riverfish, drinkingwater intake,treateddrinkingwater,tapwater,theinfluentoand effluenftrom publicly-ownedwaste treatmentworks,sludge,and municipallandfill leachate.Additionallya, "market basket"ofseveralfoodproductswillbe sampled. These include:beef,pork,chicken,hot dogs,catfishe,ggs,milk,bread,green beans, applesfrom grocerystoresand,ifpossiblep,roduce from localfarmers'markets.
The May 4,2000 data provided detailon thedesignand structureofthestudyand representtshefirstresultsfrom themulti-citsytudy.Incl" udedinthatsubmittal were reportson thequalityassuranceplan and fieldsampling proceduresused and theresultosfthedrinkingwater samples takenfrom thesixcitiesT.he results indicatethatdrinkingwater infourcitie(sDecatur,Alabama; Cleveland, Tennessee;Mobile,Alabama; and Port St.Lucie,Florida)did not containdetectable levelosffluorochemicals.Only two citie(sColumbus, Georgia,and Pensacola, Florida)containeddetectablelevelsof sulfonatedfluorochemicalisn the drinking water. See theMay 4,2000 submittalformore detailregardingthesedrinking water resultsI.ncludedagaininthissubmittalarethefieldreportsforuse in reviewingthesurfacewater data.
Subsequenttothe originalsubmittalofinformationfortheMulti-citsytudy, additionaalnalyticadlata has been obtainedforvariouswater column samplesfrom thesixcitiesS.amples were collectefdrom surfacewater sources,both flowing
streamsand inareasofquietwater.Analyseswere performed forPFOS, PFOA,
and PFOSA. Maps of the sample locationsand the data are presented in the
attacheddata sheets.
In summary, the data indicatesthat in most samples ofthe water column in flowing streams, the levelofPFOS was eitherbelow the detectionlimitof25 ppt or at levels ranging from 25ppt to 83ppt. Analyses of samples collectedfrom quietwaters in three citiesM,obile, Al, Decatur, Al, and Port St.Lucie Fl,showed the presence of PFOS in varying concentrations.There are two setsofdata and reportsfor the quietwater samples in the Port St.Lucie location.The firstsetof data, May 2000, showed anomalous results.Thus, a second setof samples were collectedand analyzed, and summarized in the report dated August 2000.
The analysesof samples of the quietwater for Mobile, Decatur, and Port St.Lucie showed levelsof approximately 30ppt, 110ppt, and 2900ppt, respectively.In general,the levelsfound in allsamples are well below the chronic No Observable EffectLevel for PFOS in both fathead minnows, and daphnia magna, both ofwhich have been determined to be 0.30 ppm. This would yielda safetyfactorsof 100 to 10,000.Itisunclear the reason for the findingin the Port St.Lucie quietwater samples, other than to note thatthe sample locationindicatedthe presence of considerablemanmade debris.
The concentrationsof the other analytes,PFOA and PFOSA, are very low,with most resultsator below the levelsof quantificationof 25ppt. At three citylocations, PFOA was found in levelslessthan 100ppt. There are no environmental effects expected at these levels.
The overallmulti-citystudy iscontinuing.Samples of the leachateand publicly owned treatment works (POTW) plantinfluentand effluentare being analyzed. Validated analyticalprocedures have been developed recentlyforvarious food stuffs,and the market basket sampling program willcommence shortly.
