MEMORANDUM

TO: All Vertac Personnel

FROM: Kathy Weinel ,;J.t(./

DATE: July 14, 1994

SUBJECT: Ash and Salt Residue Composite Procedures

The procedures for sampling, compositing and decontamination outlined in this memorandum are to be used m when preparing ash and salt residues for analysis of target inorganic and organic compounds and geotechnical analyses. The procedures outlined in this memo do not effect the implementation of the procedures outlined in Appendix F to the Work Plan. Sampling and Analysis Plan for Ash and Salt as amended May 4, 1992. Sample Selection

Table l shows the ash and salt residues that will be composited and sent for analysis·. Each group of residues, listed by URS number, will be composited to form one sample that will be sent for analysis.

Sample Cottection

After retrieving all of the appropriate to be used to form a given composite, pour the contents of several jars into a stainless steel bucket and crush the larger pieces with a geologists hammer until all pieces are smaller than 3/4 • 1 inch in diameter. Pour the contents of the metal pan into the cement mixer and repeat this procedure until all of the sample jars to be used for a given composite have been emptied into the cement mixer. Cover the cement mixer opening with plastic and tape and mix the samples until the mixture appears homogeneous. Weigh one of each type of sample (1 Liter amber and 16 oz. plastic only) to obtain an average tare weight. Fill the appropriate number of sample jars using a stainless steel scoop or spoon. Reweigh the filled sample and subtract the tare weight. This is the weight of the sample container contents. The contents of the 16 oz. plastic sample container must be at least 500 grams and the contents of the l Liter amber glass sample container must be at least 200 grams. If the contents of the container does not meet the minimum requirements stated above continue to fill the same type of sample container until the combined weight of the sample

ASH&:SAl. T .:0.1E.Vl:Kalhy6 meets or exceeds the minimum requirements. Decontaminate the exterior of the composite sample containers as described below. Place the excess composite material in 5-gallon bucketsOO and the buckets with URS . The excess composite material will be retained as an~ archive sample for future analyses. : 0 Sample Containers

Table 2 shows the sample containers that should be filled for each composite.

QA/OC

Duplicates

Samples A6 and S6 are duplicate samples of A4 and S4 respectively. Duplicate samples should be collected after compositing the residues. When forming the composites for samples A4 and S4, remember that extra volume will be needed to fill the jars that will be labeled A6 and S6. Duplicate samples will be submitted to the laboratory blind, in other words they should not be labeled as duplicates.

~1S/MSD

Extra volume of samples AS and S5 will be collected and submitted to the laboratory to ensure that the laboratory will have sufficient volume to complete their internal quality control. The extra volumes will be collected for organic and inorganic analyses only and will be labeled the same as the sample. Laboratory QC is designated on the Chain of Custody Form.

Decontamination

Sample Jars

All sample jars containing composite samples will be decontaminated as follows:

Wash the outside of the jars (make sure the is tight) with deionized water/laboratory­ grade soap solution.

Rinse the outside of the jars thoroughly.

Dry the outside of the jars with towels.

Sampling Equipment

Sampling equipment need not be decontaminated after each and every sample is composited. ~ After all of the composite samples are made sampling equipment will be decontaminated as ~ described below. If disposable sampling equipment is used, decontamination is not necessary. ~ Larger pieces of equipment such as the cement mixer will be decontaminated using a high 0 pressure washer. All decontamination fluids will be containerized and disposed of with waste l...... from other sampling efforts. ·

Wash with a deionized water/laboratory-grade soap solution.

Rinse thoroughly with deionized water.

Dry with paper towels.

• If disposable sampling equipment is used, decontamination is not necessary. Sample Labelin~

All samples will be labeled using URS labels and Chain of Custody Forms. Examples of completed Chain of Custody Forms and labels arc shown in Figures 1 and 2.

If you have any questions, please call me in the Denver office.
