1.0 INTRODUCFICMBased uj-on d r a f t result s of the recent remedial inve s t igat ion of the

F r e n c h L i m i t e d S i t e , several areas of interest have been i d e n t i f i e d whichshould be the subject of a s u p p l e m e n t a l inves t igat ion of the area. B r i e f l y ,the additional in format ion deemed de s irab l e to assess remedial opt ions forthe site are described as f o l l o w s :

1.1 Wast e Character iz aticn ~ A s i g n i f i c a n t quant i ty of data has beenco l l e c t ed over the years relat ive to soil contamination around the mainlagoon at the site. Ihe recent inve s t igat ion also included ul trasonic d e p t hmeasurements of the various strata within the lagoon, f o l l o w e d by somevibracore sampl ing of waste residues. Sel e c t ed samples of these wastes weresubjec ted to a p r i o r i t y p o l l u t a n t analysi s , and an estimate prepared of theto tal volume of waste in the lagoon and volume of surrounding contaminatedsoils. It would be h e l p f u l to have sane add i t i ona l in f ormat i on relat ive towaste quanti t i e s and characteri s t ic s:

1.1.1 Quantity - The LAN estimate of waste quanti ty current lyranges between 30,000 and 48,000 cubic yards of waste and contaminatedsub-soils wi th in the lagoon, with th i s increase over their previous estimateof 8,000 cubic yards based upon emulsion of heavily contaminated sandsbeneath the s ludge s . Since the avai lable geo log i c data indicate that the

sand layer into which the pit was excavated could have been as thick as 65f e e t , and since a f l o a t i n g barge was u t i l i z ed to .-nine the sands f r o m thispit in the early 60's, there is no conclusive evidence that the "one to *ourf e e t of heavily contaminated sands beneath the sludges" accounts for thei

j total d ep th of waste residue migration. As such, addit ional in format i onwil l be necessary to p r o p e r l y document the total waste quanti ty wi thin thepit to account for waste const i tuents which may have migrated into subgrade1 soils .

1.1.2 C o m p o s i t i o n - Ihe composi t ion of the waste s l udge s has notbeen comple t e ly d e t e rmined , in that only three samples were i n i t i a l l yanalyzed t y G C / f a S , with only base/neutral p r i o r i t y p o l l u t a n t s a n d P C B ' sreported as being present. She organic mater ia l s i d e n t i f i e d ranged f r a n atotal of 4,000 pgn to 8,000 p p n , with the range of the total extractableorganics (TOE) for those same samples ranging f r c m one to nine percent.Materia l balance is f u r t h e r conf irmed by the two supplemental samplesanalyzed by GC/ftS in Novsnber. It is, t h e r e f o r e , questionable whether muchof the organic content of the s ludge is composed of p r i o r i t y p o l l u t a n t s , andto evaluate remedial opt ions , the true composi t ion of the material should beknown.

1.1.3 Regulatory . . C l a s s i f i c a t i o n - Mo data have been reportedwhich would al low the characterization of the s ludge s under Federal or S t a t eguide l ine s . I n s u f f i c i e n t conposit ional data are avai lab l e to evaluate thep o s s i b i l i t y of l i s t ed wastes having entered the lagoon, and the RCRAcharacteri s t i c analyses were not conducted. Waste material t e s t ing underRCPA procedures is necessary to c l a r i f y c l a s s i f i c a t i o n ,

1.1.4 Other f f a s f c e s - Ihere is substantial evidence that municipalwastes have been l a n d f i l l e d in the area, including a large County operated

II municipal l a n d f i l l near the French Limited lagoon. Since municipall a n d f i l l s were not closely monitored prior to 1976, industrial wastes and/orhazardous municipal wastes may have been managed at that s i te, Hiepo t en t ia l . m u l t i p l e e f f e c t s of the County l a n d f i l l and the French Limi t edlagoon on area groundwater have not been considered.

1.2 PCS Considerations - The current s t u c f y has provided only f o u r PCBanalyses of the waste within the main p i t . Two of these values were below50 p p n , one at about 80 p p n , and the other near 500 ppm. Thes e data ares t a t i s t i c a l l y inadequate to evaluate a p p r o p r i a t e remedial actions.

1.3 Geohydrologi ca l Evaluation - Of the 17 ground*ater monitor w e l l sr e p o r t e d l y ins tal l ed in the upper water bearing zone during the LANinvest igations, most are not u s e fu l in evaluat ing the hydro logy of po t ent ia lsub sur face migration f r o m the French Limited lagoon- T h i s is due to am u l t i t u d e of problems observed in well location, pr imari ly due to thecomplex geology of the site. F o u r w e l l s are u s e fu l but they could bea f f e c t e d by the "mounding e f f e c t " of the lagoon. T h e r e f o r e , in order todeve lops a more comprehensive d e f i n i t i o n of the compl i ca t ed s i teh y d r o g e o l o g i c condit ions , addi t ional monitor we l l s within the shal low waterbearing s tratum would be necessary.

1.4 Conclusion - Based upon these observations, it is recotmended thatsome addi t ional f i e l d and laboratory e f f o r t be expended to c l a r i f y the aboveissues so that the f e a s i b i l i t y of avai lab le remedial opt ions for siteclosure may be p r o p e r l y assessed. S p e c i f i c a l l y , the f i e l d s a m p l i n g andanalytical programs outlined in Sec t i on s 2 and 3 of this report should beconducted to supplonent those data alreaoV available.

2.4 S a f e t y and Chain of Cus tody Procedures - The s a f e t y p l a n to bef o l l o w e d dur ing f i e l d s a m p l i n g programs, along with the Chain o f Custodyprotocol for documenting samples , is described as part of the f i e l d programprocedures in Attachment No. 2.

f ran shal low areas and two f r o m deep areas of the lagoon) will be pr eparedin the f i e l d for analysis. These waste samples along with onerepre sentat ive leachate sample f r o m the municipal l a n d f i l l will be analyzedas f o l l o w s :

3.1*1 Organic Evaluation - "Hie f i v e samples will be evaluated byGC/MS for a l l three p r i o r i t y p o l l u t a n t f r a c t i o n s , and an estimated f i f t yaddit ional organic peaks i d e n t i f i e d and q u a n t i f i e d . These data will then beu t i l i s e d to es tabli sh a "library" of organic consti tuents to be preservedw i t h i n the mass spec computer for f u t u r e correlat ion with otherenvironmental samples.

3.1.2 Inorganic Evaluation - The twelve TCWR "heavy metals* 1,along with sodium, calcium, potas s iun, magnesium, vanadium, molybdenum,iron, b e r y l l i u m , l i t h i u m , and cobalt will be evaluated by atomic absorpt ionanalysis o f acid diges ted samples.

I3.2 Subsoil Contamination . P r o f i l e - S a m p l e s of subgrade soil s beneath

; the lagoon and f r o m ad jac en t soil borings will be evaluated fori contamination based upon " f i n g e r p r i n t " parameters i d e n t i f i e d f r a n the abovei

I s ludge analyses. The probable analyses to be u t i l i z e d for this purpose arei

| TtX and phenol i c s to indicate organic contamination; zinc, chronium, andlead to indicate heavy metal contamination; and, ch lor ide and s u l f a t e toindicate inorganic migration. S u f f i c i e n t samples will be analyzed toevaluate soil attenuation of each of these classes of cons t i tuent s , bothver t i ca l ly and rad ia l ly f r o m the waste/soi l in t er fac e .

3.3 PCB_ .Concentrations - Ifce waste samples will be analyzed byelection capture GC/MS to determine the total P03 content, as well as theconcentration of the various Aroclor isomers. Total KB concentrations willthen be determined in selected soil samples chosen f r o m the migrationanalysis under 3.2. The primary ob j e c t iv e s of thi s eva lua t i on will be todetermine the Aroclor isomer ratios, and total concentrations re lat ive toregulatory levels.

3.4 H y d r o l o g i c . Gradient - S u f f i c i e n t g round/a t e r level measurementswill be conducted on some ex i s t ing w e l l s and the f o u r new w e l l s to evaluatethe hydraul i c gradient within the uppei water bearing stratun. W a t e r levelmeasurements w i th in the French Limi t ed lagoon, other adjacent ponds, and theSan J a c i n t o River will also be obtained s imultaneously to evaluate po t en t ia lmounding and di scharge e f f e c t s .

will be in s ta l l ed in the near vicinity of the French Limited site. Soi lborings wi th in t enni t t en s a m p l i n g will be advanced using rotary washd r i l l i n g techniques. F o l l o w i n g the c o m p l e t i o n of the soil bor ings , thee x i s t i n g soil boring hole will be reamed wi th an 8-inch diameter bit for i t s 'f il d e p t h . At the conclusion of the reaming o p e r a t i o n s , t hr eaded ,f l u s h - j o i n t schedule 40 PVC casing will be set wi th in the reamed hole. T h i s o

j'lush- j o i n t e d casing wil l be machine s l o t t ed at 0.20 inch wid th s t hroughou t 0 |J^he l ength of the bore hole to be monitored for groundwater. The screenedp o r t i o n of the casing wil l also be wrapped wi th a g e o t e x t i l e f i l t e r f a b r i c( F i b e r t e x , Grade 150) .

A f t e r s e t t i n g the casing to the des ired d e p t h , the bore hole wi l lbe f l u s h e d of d r i l l i n g f l u i d s by pumping clean water down through the casingand out through the screen and a spr ing- l oaded check valve at the bottom ofthe casing. F l u s h i n g of the bore hole wil l continue until the return f l o wof water is f r e e of d r i l l i n g mud a d d i t i v e s or natural mud. F o l l o w i n g thef l u s h i n g of the bore hole, the annulus of the casing wi l l be b a c k f i l l e d withclean f r e e dra in ing sand to a minimum of two f e e t above the top of thescreened p o r t i o n of the casing. A f t e r the sand b a c k f i l l has been p l a c e d ,

e rthe remaining p o r t i o n of the casing annulus will be f i l l e d with a cement/bentonite slurry mix. vented p l a s t i c cape will be placed on the WC casing,and l o c k i n g 5-foot long metal pro t e c tor casing wi l l be placed on top of thewells. Ttie protective casing will be concreted into place. Detail s of thewell c ons truc t i on are presented in the attached f i g u r e .

1.2 M o n i t o r Wel l Development - The monitor w e l l s will bedeveloped by removing approx imate ly 3 to 11 time the volime of water withinthe casing. As a minimum, the w e l l s w i l l be purged unti l the water c l a r i t y ,has s i g n i f i c a n t l y improved. As an additional aid in evaluat ing the w e l l ' s ^d eve lopment , the conduc t iv i ty , £ f l , and t empera tur e of the evacuated water0

Owill be measured. the amount of water in and purged f r o m the well as we l loas the physical p r o p e r t i e s measured dur ing the p u r g i n g of the well wi l l berecorded. The well s will be deve loped by evacuating the water f r o m themonitor w e l l s using a 175 cfm air compressor. A 3/4-inch air hose will belowered to the bottom of the well where it w i l l be maintained toa p p r o x i m a t e l y 85 to 100 psi d u r i n g the development process. W a t e r obtainedf r o n the w e l l s wil l be d i s charged into b a r r e l l s try using an invertedU-shaped d iver t er placed over the top of the casing. The volume of theevacuated water will be recorded and then placed into the main lagoon toprevent any p o t e n t i a l contaminat ion of the area.
