Groundwater monitoring/sampling procedures

GROUNDWATER MONITORING PROCEDURES
Required Notifications/Review

1. Prior conducting any field work, the client, regulatory agency, and property owner/manager are notified in writing via facsimile or email. If possible, a minimum of 48 hours notice will be provided prior to conducting the field work.

2. If available, construction details of all wells will be reviewed prior to field work being conducted. This will allow determination in the field of special conditions such as; groundwater levels above or below screened interval.

Water Level/LNAPL Measurements

1. During the groundwater monitoring phase of the fieldwork, all wells are monitored for light non-aqueous phase liquid (LNAPL) using a clear plastic bailer or interface probe.

All equipment is cleaned prior to and between locations via a steam cleaner or “three bucket wash” method.

2. Water level is measurements are taken in order from the historically “cleanest" wells to historically "most contaminated" wells.

3. Water levels are measured using an electronic measuring device (±0.01 foot) and are referenced to the surveyed datum (well cover or top of casing). If no survey mark is noted on the well cover, the well is marked with a permanent notch or marker on the north side of the cover for future consistent readings.

4. Recorded measurements include the depth to groundwater, depth to LNAPL and depth to bottom of well.

5. If possible, all wells are gauged on the same day to obtain accurate measurements of the potentiometric surface.

6. If LNAPL is encountered, the potentiometric surface elevation is calculated as:

DTWc = DTWm – (Tsph X SGsph)
Where: DTWc = Corrected Depth to Water
DTWm = Measured Depth to Water
Tsph = Thickness of LNAPL
SGsph = Specific Gravity of LNAPL

Page 850 of 1199 ends

Groundwater monitoring/sampling procedures
If SGsph is not known, the following will be assumed:

Gasoline 0.75 g/cm3

Diesel 0.81 g/cm3
Jet Fuel (JP-4) 0.79 g/cm3
#2 Fuel Oil 0.91 g/cm3
#6 Fuel Oil 0.96 g/cm3

7. All monitoring data is recorded on field data sheet, reviewed, transferred to a data base and incorporated in the final reporting.

Page 851 of 1199 ends

Groundwater monitoring/sampling procedures

GROUNDWATER SAMPLING PROCEDURES
Wells Exhibiting LNAPL
If a well exhibits measurable LNAPL thickness, sampling will not be conducted. Instead the LNAPL will be bailed from the well to the extent possible within the purging timeframe. Should a groundwater sample be required by the regulatory agency for the project, a sample is collected from the groundwater retained in a bailer lowered below the LNAPL. Wells containing LNAPL will not be purged.

Sample Collection - Purging Method

1. Wells are selected in order of increasing contaminants historically detected.

2. Integrity of the well cover, well cap and top of casing are established and noted for future reference.

3. Non-dedicated equipment is decontaminated using a steam cleaner or "three bucket" wash.

4. Depth to water, depth to LNAPL (if present) and total depth of well are determined using an electronic water level indicator or interface gauging probe in accordance with the monitoring procedures outlined.

5. Generally, well casing volume is calculated for estimating the total minimum purge volume required. The borehole volume will be used, as follows:

Bv = 7.48*[{3.14(Cd/2)2 +3.14P[(Bd/2) 2 – (Cd/2)2]}*(Dw-DTW)] Where: Bv = Boring volume in gallons

7.48 = gallons per cubic foot
Cd = casing diameter in feet
P = porosity of the sand/gravel pack
Bd = boring diameter in feet
Dw = depth of the well in feet
DTW = depth to water

6. Groundwater is removed from the well by bailing or pumping (using a diaphragm, down hole pump or vacuum truck) until it is determined that the well is beginning to dry or until at least four (4) well volumes have been purged and water quality parameters (pH, conductivity, turbidity and temperature) stabilized (within 10 percent of previous reading).

When purging via bailing or use of pumps, the purge water is discharged into DOT-approved

Page 852 of 1199 ends

Groundwater monitoring/sampling procedures
55-gallon drums and is stored onsite, temporarily, for subsequent proper disposal by the generator. Disposal methods used by the generator are either off-site disposal by subcontracting a certified waste transporter to remove the stored purge water and properly dispose of the purge water at a recycling facility or use of an on-site groundwater treatment system for the treatment and discharge into either the local storm drain in accordance with an NPDES permit, reinfiltrated in accordance with a WDR permit. If groundwater is removed using a vacuum truck, the vacuum truck will store the purged water and transport it off-site to a waste disposal facility for recycling. Waste manifest will be available once received from the recycling facility.

7. After the well has recovered at least 80 percent or within two hours of purging, a sample is collected just below the water surface using a bailer (teflon, stainless steel or disposable bottom emptying) and placed into laboratory supplied containers. The containers are completely filled and the cap immediately placed over the top and securely tightened. Vials are inverted and tapped to determine if air bubbles are present. Samples are labeled, and placed on ice in an ice chest until delivery to the laboratory.

8. The following equation is used to determine 80 percent recovery:

Rdtw = Dw – (WCl X0.8)
Where:

Rdtw = Recharge DTW (maximum for 80 % recovery)
Dw = Depth of well, in feet
DTW = Depth to water
WCl = Water column length (TDw – DTW)
Sample Collection – Micro-Purge Method

1. Wells are selected in order of increasing contaminants historically detected.

2. Integrity of the well cover, well cap and top of casing are established and noted for future reference.

3. Non-dedicated equipment is decontaminated using a steam cleaner or "three bucket" wash.

5. Groundwater is purged from the wells using a submersible, bladder or other downhole

Page 853 of 1199 ends

Groundwater monitoring/sampling procedures
pump at sufficiently low rates (about 0.05 to 0.5gal/min) of withdrawal that keep drawdown, aeration, and turbulence to a minimal.

6. Generally, the pump intake is positioned in the mid-point of the saturated screened interval, but a different position may be used based on hydrogeologic conditions and/or analyte properties. For petroleum hydrocarbon and oxygenate sample analysis, the pump intake is placed in theupper third of the saturated screened interval. The type of pump, flow rate, total volume of water removed, and depth of the pump intake are noted on the field log. Low-flow purging continues until temperature, pH, turbidity and conductivity stabilize. A sample is then collected from the purge water effluent stream or from a bailer.

7. For low-flow purging, water quality parameters are continuously monitored during purging as opposed to interval monitoring from standard purging. A flow through meter, Horiba 22 or equivalent, is incorporated.

Sample Collection - No Purge Method

1. Integrity of the well cover, well cap and top of casing are established and noted for future reference.

2. Non-dedicated equipment is decontaminated using a steam cleaner or "three bucket" wash.

3. Depth to water, depth to product (if present) and total depth of well are determined using an electronic water level indicator or interface gauging probe (0.01 accuracy).

4. A sample is collected just below the water surface using a bailer (Teflon, stainless steel or disposable, all bottom emptying) and placed into a laboratory supplied vial. The vial is completely filled, cap immediately placed over the top and securely tightened. The vial is inverted and tapped to determine if air bubbles are present. If none, the sample is labeled, and placed on ice in an ice chest until delivery to the laboratory.

Quality Control/Quality Assurance

1. The field data sheet is completed with all pertinent data such as; well integrity, purged water volume, pH, turbidity, temperature, and specific conductance, if available.

2. The samples are transported to the laboratory as soon as possible following chain-of-custody procedures. In the event a holding time of greater than 7 days is required, the laboratory will be requested to supply vials with the appropriate preservatives for the analyses requested.

3. Wells are sampled from the order of least to highest historic concentrations, if known.

Page 854 of 1199 ends

Groundwater monitoring/sampling procedures

4. Site conditions are noted which may potentially contaminate the sample i.e. smoke, vapors from running engines, etc.

5. If a single bailer is used for collection of all samples, an "equipment blank" sample will be collect following the same protocol of sample collection. The same water supply used to rinse the equipment will be used to collect the blank sample.

6. A trip blank, if required, supplied by the analytical laboratory will be stored and transported with the samples until their delivery back to the laboratory.

7. The blank samples will be analyzed for all constituents.

8. A duplicate sample will obtained and analyzed as requested.

Sample Shipment and Chain-of-Custody
Complete records are kept on each sample including sampling date, sample type, location, and other pertinent information. The sample containers are banded and sealed with chain-of-custody seals.

The samples are chilled in an ice chest using block or blue ice. Care is ensured not cause sample freezing which may result in container breakage during transport to the laboratory.

Chain-of-Custody procedures, generally described in Test Methods for Evaluating Solid Waste, SW846, U.S. EPA, 1982, are followed. A chain-of-custody form accompanies the sample from the place of collection to the laboratory, and through the completion of the analytical process. The chain-of-custody form includes project identification information, the sample type and number, the date and time of sampling, the chemical analyses requested, and the identity of the person taking possession at each change of custody.

Equipment Cleaning
When steam-cleaning is not available, the "three bucket" wash is used. The three bucket wash consists of an Alconox® solution cleaning, a tap water rinse and a distilled water rinse. No solvent (hexane) rinses will be used. For bailers, the Alconox® solution is flushed completely through the inside followed by flushing with tap and distilled water. When submersible, bladder or doublediaphragm pumps are used (non-dedicated), the solution of Alconox® is cycled through the pump body and hoses followed by similar water rinses.

Page 855 of 1199 ends

Groundwater monitoring/sampling procedures
Waste Storage and Disposal
The effluent and/or decontamination and/or purge water generated during the testing, equipment cleaning or groundwater sampling are placed in DOT-approved, 55-gallon, drums. The drums are sealed, labeled and stored on site pending subsequent proper disposal/treatment by the generator. As previously mentioned in the Sample Collection-Purge Method section, Disposal methods used by the generator are off-site disposal by contracting a certified waste transporter to remove the stored purge water and properly dispose of the purge water at a recycling facility or use of an on-site groundwater treatment system for the treatment and discharge into the NPDES, WDR or Industrial Waste Discharge permitted storm drains, re-infiltration wells or sewer, respectively. If groundwater is removed using a vacuum truck, the vacuum truck will store the purged water and transport it off-site to a waste disposal facility for recycling. Waste manifest will be available once received from the recycling facility.
