Sand City Dump Reconfiguration Project Sample Collection and Screening Procedures

Purpose: To provide step-by-step procedures for sample collection and sample screening for the Sand City Dump reconfiguration project.

1. Before proceeding to sample collection location, check with site construction superintendent and let him know where, when and how long you will be sampling. Check sample grid map and annotate grid location on sample log.

2. Don appropriate personal protective equipment (PPE) as required by site PPE operating levels. Minimum PPE required is chemical resistant (PVC, nitrile, butyl rubber, etc.) gloves for sampling.

3. Determine if screening testing will be performed at a location other than the soil sample collection location, i.e. set-up a testing table near the Granite construction trailer.

4. Bring sample collection and screening materials and equipment as required. The equipment and materials will include as follows:

Sample Collection Only
5 ea	Sample collection containers with lids
5 ea	Screening test containers
2 ea	Stainless steel sampling spades or scoops
1 ea	Self-adhering labels for samples containers
2 ea	Indelible ink pens
1 ea	Ice chest with icepacks
1 roll	Tamper-proof sealing tape
Screening Equipment Only
1 ea	GasTech Combustible Gas Indicator (CGI)
1 ea	Organic Vapor Meter (OVM)
1 ea	pH/Conductivity/Temperature Instrument
1 ea	Draeger pumps and applicable Draeger Tubes (VC/TOL/BEN/H2S)
1 pack	pH indicator test paper
1 pack	Acidified Potassium Iodide Indicator Paper (KI)
1 pack	Acidified Lead-Acetate Indicator Paper
1 pack	Cyantesmo Test Indicator Paper
1 bottle	Lab Grade Sulfuric/Hydrochloric Acid Reagent
1 kit	CLOR-N-OIL
1 kit	CLOR-D-TECT
1 gal	Distilled or deionized water
1 ea	24 oz spray bottle
1 roll	paper towels

5. When at sampling location, observe soil to be sampled and determine if authoritative sampling will be performed based on conditions. Also determine if soil sample will be tested for laboratory analysis other than total lead concentrations (see sampling and analysis plan). If additional testing will be performed, annotate on sample screening log and annotate additional tests on analysis request form. Keep track of budget for number of samples analyzed for multiple tests (10 is limit).

6. Obtain sample, by scooping soil, waste material, etc. with stainless steel spade and place in sample container. Annotate soil or waste physical description on the sample log (solid, semisolid, liquid, gas, color, etc.). Also obtain samples in the 4 screening test containers (1 for OVA, 1 for CGI, 1 for oxidizer, sulfide, pH, 1 for cyanide).

7. For sample to be sent to laboratory for analysis (either lead or suite-testing), place self-adhering label on container and annotate sample collection identification number (grid number and waste layer designation and date, e.g. A01RE0316, which is grid A1, refuse layer taken on 03-16-96) name of site, sampler initials, time and date. Place tamper-proof sealing tape on lid and jar. Place jar in ice chest. Tape thermometer to lid of ice chest to verify that temperature is 4 degree Celsius.

8. Fill out chain-of-custody document and analysis request form. Package and send to laboratory as soon as possible or when designated.

9. Using the organic vapor analyzer (OVA) and sample screening container filled with sample, obtain a head-space gas concentration measurement by inserting OVA probe into hole in lid of container (or other method, i.e. plastic wrap). Record measurement on sample log. After completion of test, dump soil contents back on-site and decontaminate screening jar using distilled water and paper towel (do not use chemicals). If soil contaminates container with substance uncleanable by distilled water, discard container (possibly consider further tests).

10. Using the CGI, perform head space testing as described in No. 9. Record measurement on sample log. Follow same decontamination procedures described in No. 9.

11. If OVA or CGI measurements are greater than 10,000 ppm (1% gas), perform Draeger tube testing using vinyl chloride, benzene and toluene. Obtain additional samples as necessary. Annotate any Draeger tube test results in the sample log. Consider sending sample to laboratory for organochlorine/pesticides, total halocarbons, or 8240 suite etc.

12. If sample material has oily sheen or contains oily substance, consider running CLOR-N-OIL test for PCBs or CLOR-D-TECT test for Halocarbons. Consider sending sample to laboratory for total petroleum hydrocarbons (TPH) and organopesticides/PCBs.

13. To perform water reactivity test, place 4 oz or more of distilled water in designated screening container until sample is saturated. Gently agitate container for 10-20 seconds. Let stand for five minutes. Annotate any visible reactions (fuming, polymerization, etc.). Pour liquid content from container into small test container.

a) for pH test, place strip of pH indicator paper in test container, remove and observe any color change in the paper. Annotate pH indication in the sample log.

b) using a dropper, obtain liquid from sample container and place in test cup on EC/pH meter. Annotate electronic conductivity and pH measurements.

c) for oxidizer test, place acidified potassium iodide (KI) paper in test container and annotate color change indication (positive or negative for oxidizer) in sample log.

d) for sulfide test place acidified lead-acetate paper in test container and annotate color change indication (positive or negative for oxidizer) in sample log.

14. For Cyanide Indication Test, obtain small sample (4 oz) and place in small test container (4 oz), place distilled water in container (about half way). Apply drops of acid reagent unit pH is about 2 or less; check using pH paper the amount of acid required for the amount of distilled water and sample material. Using Cyantesmo indicator test paper, measure if sample is positive or negative for cyanide.
