Dear Mr Joyce

we the Cltiaena Advisor) CoDD1ttee for the Reaolve Inc Supershyfund alte bafl reviewed the EPA Peaa1b1lltJ Stu4J of remedial reshyaponata optlona for cleanup of the alte and otter the followllli conte on the proposal

We have orsanlud our ooaaenta into two cateamporha the tlrat being thoee relatinamp to the actual cleanup procedurea and the second beshying thoae relating to the presentation of tM report itself

Beoauae bullbull are dealing with clllllloal mixturebull or aolut1ona bullbull cannot laolate one contaminant from another We have to look at the IJU~trBbtlo ettecta eg interaction or metals with organic aolventa

1 Groundwater paplng and treatment should not be atarted bulllmtil tM boriaontal dhtribution ot all ot the contaminants are well defined heretore we would sugge1t that other welle be drilled down to bedrock but not into it

2 4re there aeparate pbaeea of denampe non-aqueoua-phaae liquida on top of the bedrock andor on top ot aem1-perMable aUt or clay layerbull above bedrookf We would like to aee more testing to deshyterwlne tbia

) The Feasibility Study 1e baaed on 1983 data What concentrashytions will there be when the work 1a begunf We would like to aee a continuum or the data up to the point of the final cleanup

4 Previoua experience haa ahown that during the excavation proceaathe eacape of VOCa will be a problem especially on a hot art1or windf da7 What meaaurea will be employed to control thia em1ashyaionf

) Will an encloaure be used above the lS x l S area being treated It one 1a not being used why notf

6 The report indioated high leYela ot oa4miID in aome placeaFurther anal7ah ahould be made to deteN1ne the 1nteraot1on of organic solvents and heavy me tale in particular cadmium and lead What remedial aot1on 1e planned tor theae heavy metalat

1 Dati from other sitea being treated with the dechlorination prooeaa ahould be available for review prior to the atert or the pilot study at the Resolve alta ihere abould be public review on this Data from the pilot study at the Resolve aite should also be made available for review (a public hearing) before continuing with thai dechlorination proeeaa Thla data ahould include not only the d1aappearance or the PCB a but the analyaia of all the products of the dechlorination proceae The data should also include updated coat figurea

8 Bven though the question of the POBbulla may require further s tudy ranoval of the VOC 1 a ahould proceed since that technologJ 11 not 1n question middot middot

To belp ua in our a tudy or the cleanup process would you pleaae arranae to turniah the following

1 A larger more legible version of the map Pig 4-6 Total VOCs Concentraion Overburden Aquifer

2 The laboratorJ reports ehowlng diatrfbution of contaminant ot each well and the concentration of eachbull

) What are the boundariea direction of movement and rate of aovement or the contaminldtaa and where are the wella in reshylation to the boundaries or contu1nat1ont

4bull We would like a more specific llat of all contaminanta in particular tbe VOCbull toun4 on the aite and an analyale or ~ which are ~ing removed and which are not baing removed The abaence or dJbenzoparadioxina and polychlorinated dishybensoturaiUI should be contirmed

S We reel that the testing ot privata welle on a regularlJ acheduled basia during the entire cleanup proceaa ahould be a prioritJ

~~r~~rd~t~~tnlhh~~~~ol~a~~~~t~~c~~~~~ PCBbull will be Wldertaken eimultaneoualy and will work in conjunction with eaoh other We feel atronglJ however that any lack or experishyence with the dechlorination proceas bullbould not be allowed to delaJ in any way the etartup of the known anqProven groundwater treatment

It it 1a poaaible to etart tlia pumpng and treating oothe VOCe in the groundwater befor~t ia poaaible to initiate the dechlorination ot the PCBbullbull we reel that the groundwater treatment should not be delayed Since the VOC 1 a are reaponaible tor the mobility or the PCBbullbull their early treatment will contribute to control or both preblebullbull bull

We are pleased to note that BPA 1 a preferred alternative tor PCB treatllent 18 dechlorination Although the proceaa is relatively unknown and unproven it 1a imperatill that auch new tecbnologiea be explored Since the 08 problem 1e a worldmiddotwide one every new experience with ita treatment or control provides an important aoishyentitic link

We look forward to continued cooperation with IPA in the 11J18ditioua cleanup ot the Resolve alta
