RE: Third Quarter 1996 Groundwater Monitoring Data Report
Dear Marshall:
This report presents groundwater monitoring data collected during August 1996. Collection
of data and preparation of this report was completed in accordance with the Phase III Monitoring
Plan for the Former Waste Disposal Site (Geraghty & Miller, Inc. 1989) and revisions to the plan
made over the last several years. During the third quarter, fluid-level measurements were collected
from site-wide bedrock wells and unconsolidated wells at the Former Waste Disposal Site shown on
Figure 1 and Figure 2, respectively.
Groundwater samples were collected from bedrock well LI and residential well BE236
located along South Bellingham Street and analyzed for VOCs by Method 8260 to achieve the
lowest possible detection limits. Quarterly monitoring data reports prepared during 1996 will be
summarized in an annual report for 1996 groundwater monitoring activities at the Alcoa-Davenport
Works. The annual report will discuss trends observed during 1996 with respect to water and
product elevations and the results of groundwater quality sampling.
SITE-WIDE WATER-LEVEL MEASUREMENTS
Water-level elevations were measured from site-wide bedrock wells on August 20, 1996 and
are summarized in Table 1. Figure 3 illustrates the distribution of groundwater elevations and
groundwater contours depicting flow measured from intermediate-depth bedrock wells. Figure 4

illustrates the distribution of groundwater elevations and groundwater contours depicting flow
measured from deep bedrock monitor wells.
Flow meter readings from plant production well PW-06 indicated that 9,317,875 gallons
were pumped July 1996 through August 1996. No groundwater was pumped from PW-06 from July
16, through July 29, 1996; however, average pumpage from PW-06 was maintained at an
approximate rate of 87 gallons per minute (gpm) during July 1996 and 121 gpm during August 1996.
Increased pumpage from PW-06 during August 1996 resulted in a more pronounced cone of
depression than was seen during the first and second quarters of 1996. Site-wide groundwater flow
conditions observed during the third quarter continue to show site-wide groundwater capture.
FORMER WASTE DISPOSAL SITE
Water-level and product-level measurements were collected at the Former Waste Disposal
Site on August 20, 1996 using a product/water interface probe. Water-level elevations, adjusted
water-level elevations, and product thicknesses are summarized on Tables 2 and 3. The distribution
of adjusted water-level elevations at the Former Waste Disposal Site are shown on Figure 5. The
distributions of product thicknesses in monitor wells at the Former Waste Disposal Site are
illustrated on Figure 6. Contours of groundwater elevations and arrows depicting groundwater flow
direction near the Former Waste Disposal Site are presented on Figure 7. The contours and flow
directions indicate that flow conditions are similar to previous quarterly and semi-annual
groundwater monitoring events.
GROUNDWATER-QUALITY SAMPLING AND ANALYSES
Groundwater samples collected from bedrock well LI and residential well BE236 were
analyzed for VOCs by SW-846 Method 8260. A trip blank (used to determine if any cross-
contamination has occurred during sample collection, handling, and laboratory analysis) accompanied

the samples during collection and shipment. All samples were submitted to Quanterra Environmental
Services at 4101 Shuffel Drive NW, North Canton, Ohio 44720. Results of VOC analyses for
groundwater samples are summarized in Table 4. The laboratory analytical report is provided in
Attachment A.
VOCs 1,2-dichloroethene (total) and trichloroethene were detected in bedrock well LI at
concentrations of 10 |j,g/L and 1.8 u.g/L, respectively. Methylene chloride was validated as not
detected in bedrock well LI, residential well BE236, and Trip Blank TB-1 due to method blank
contaminations. No other VOCs were detected in LI or BE236 during the third quarter.
If you have questions or comments about this data report, do not hesitate to contact us.

CM - Collection manhole.
Where free-phase product is present in monitoring wells, the water table is depressed due to the mass of the product.To determine the elevation of the water table in absence of product, the following equation is used:
ADTW = DTW - SpG (PT)
Where: ADTW = Corrected depth to water (feet).DTW = Measured depth to water (feet).SpG = Specific gravity of hydraulic oil or used electrical insulating oil (0.87).PT = Product thickness (feet).

CASE NARRATIVE
The following report contains the analytical results for two water samples and one quality controlsample submitted to Quanterra-North Canton by Geraghty & Miller from the ALCOA 3rdQuarter Groundwater Monitoring Site, project number OH0900.085 Task 1. The samples werereceived August 22, 1996, according to documented sample acceptance procedures.
Quanterra utilizes only USEPA approved methods and instrumentation in all analytical work. Thesamples presented in this report were analyzed for the parameter listed on the following page inaccordance with the method indicated. Results were provided by facsimile transmission to AliceWaldhauer on September 3, 1996. A summary of QC data for these analyses is included at therear of the report.
The results included in this report have been reviewed for compliance with the laboratory QA/QCplan. All data have been found to be compliant with the exception of those items noted.
Methylene chloride, a common laboratory contaminant, is present in the GC/MS Volatiles MethodBlanks associated with QC batches 6243137 and 6247165. This commonly detected laboratorycontaminant may be present if the concentration of the analyte is less than five times the reportinglimit.
The volatile organics MS/MSD associated with QC batch 6243137 exhibited percent recoveriesoutside laboratory acceptance criteria for Chlorobenzene. The laboratory performs MATRIXSPIKES (MS) and MATRIX SPIKE DUPLICATES (MSD) to indicate any matrix effects withina given sample. They also allow the laboratory to gather precision and bias data for a specificmethod and matrix. Since matrix effects may bias percent recovery, the laboratory performscorrective action if the precision (RPD) criteria of the MS/MSD is not met.

Quanterra Incorporated conducts a quality assurance/quality control (QA/QC) program designed to providescientifically valid and legally defensible data. Toward this end, several types of quality control indicators areincorporated into the QA/QC program. These indicators are introduced into the sample testing process to providea mechanism for the assessment of the analytical data.
PC BATCHEnvironmental samples are taken through the testing process in groups called QUALITY CONTROL BATCHES(QC batches). A QC batch contains up to twenty environmental samples of a similar matrix (water, soil) that areprocessed using the same reagents and standards. Quanterra requires that each environmental sample beassociated with a QC batch.
Several quality control samples are included in each QC batch and are processed identically to the twentyenvironmental samples. These QC samples include a METHOD BLANK (MB), a LABORATORY CONTROLSAMPLE (LCS) and, where appropriate, a MATRIX SPIKE/MATRIX SPIKE DUPLICATE (MS/MSD) pair or aMATRIX SPIKE/SAMPLE DUPLICATE (MS/DU) pair. If there is insufficient sample to perform an MS/MSD oran MS/DU, then a LABORATORY CONTROL SAMPLE DUPLICATE (LCSD) is included in the QC batch.
LABORATORY CONTROL SAMPLEThe Laboratory Control Sample is a QC sample that is created by adding known concentrations of a full or partialset of target analytes to a matrix similar to that of the environmental samples in the QC batch. The LCS analyterecovery results are used to monitor the analytical process and provide evidence that the laboratory is performingthe method within acceptable guidelines. Failure to meet the established recovery guidelines requires therepreparalion and reanalysis of all samples in the QC batch. The only exception is that if the LCS recoveries arebiased high and the associated sample is ND for the parameter(s) of interest, the batch is acceptable. Consultationwith the client should take place.
At times, a Laboratory Control Sample Duplicate (LCSD) is also included in the QC batch. An LCSD is a QCsample that is created and handled identically to the LCS. Analyte recovery data from the LCSD is assessed in thesame way as that of the LCS. The LCSD recoveries, together with the LCS recoveries, are used to determine thereproducibility (precision) of the analytical system. Precision data are expressed as relative percent differences(RPDs). Failure of the RPDs to fall within the laboratory-generated acceptance windows requires the repreparationand reanalysis of all samples in the QC batch.
METHOD BLANKThe Method Blank is a QC sample consisting of all the reagents used in analyzing the environmental samplescontained in the QC batch. Method Blank results are used to determine if interference or contamination in theanalytical system could lead to the reporting of false positive data or elevated analyte concentrations. All targetanalytes must be below the reporting limits (RL) except for the common laboratory contaminants indicated below.
Volatile (GC or GC/MS) Semivolatile (GC/MS) Metals
Methylene chloride Phthalate Esters CopperAcetone Iron2-Butanone Zinc
Lead*
* for analyses run on TJA Trace ICP or GFAA only
The listed volatile and semivolatile compounds may be present in concentrations up to 5 times the reporting limits.All other organic analyte concentrations must be below the reporting limits. The listed metals may be present inconcentrations up to 2 times the reporting limit or must be twenty fold less than the results of the environmentalsamples. Failure to meet these Method Blank criteria requires the repreparation and reanalysis of all samples inthe QC batch.

QUALITY CONTROL ELEMENTS OF SW-846 METHODS
MATRIX SPIKE/MATRIX SPIKE DUPLICATEA Matrix Spike and a Matrix Spike Duplicate are a pair of environmental samples to which known concentrationsof a full or partial set of target analytes are added. The MS/MSD results are determined in the same manner as theresults of the environmental sample used to prepare the MS/MSD. The analyte recoveries and the relative percentdifferences (RPDs) of the recoveries are calculated and used to evaluate the effect of the sample matrix on theanalytical results. When evaluating the MS/MSD data, special attention is given to the RPD values. When thesevalues fail to meet acceptance criteria, the data is reviewed to determine the cause. If, in the analyst's judgment,sample matrix effects are indicated, no corrective action is performed. Otherwise, the MS/MSD and theenvironmental sample used to prepare them are reprepared and reanalyzed.
For certain methods, a Matrix Spike/Sample Duplicate (MS/DU) may be included in the QC batch in place of theMS/MSD. For the parameters (i.e. pH, ignitability) where it is not possible to prepare a spiked sample, a SampleDuplicate may be included in the QC batch.
SURROGATE COMPOUNDSIn addition to these batch-related QC indicators, each organic environmental and QC sample are spiked withsurrogate compounds. Surrogates are organic chemicals that behave similarly to the analytes of interest and thatare rarely present in the environment. Surrogate recoveries are used to monitor the individual performance of asample in the analytical system.
The Pesticide/PCB, PAH, TPH and Herbicide analytical methods require that one of two surrogate compoundsmeet acceptance criteria. All other organic analytical methods require every surrogate recovery to be within theestablished control limit. The acceptance criteria does not apply to samples that are diluted. If the dilution is morethan 5X. the recoveries will be reported as diluted out. All other surrogate recoveries will be reported. If the LCSor the Method Blank surrogates fail to meet recovery criteria (except for dilutions), the enure batch of samples isreprepared and reanalyzed. If the surrogates in an environmental sample do not meet the recovery criteria, onlythe sample is reprepared and reanalyzed to confirm the matrix effect.
