RE: Environmental Covenant for Resurrection Mining Company's Zone B Properties 

Dear Carl, 

The enclosed Environmental Covenant for Resurrection Mining Company's Zone B properties has now 

been executed by all parties and filed with the Lake Coimty Recorder. 

As you know, the Colorado Environmental Covenant statute, C.R.S. § 25-15-321 to 327, requires that 

local govemments notify the CDPHE when they receive applications affecting land use or development 

of land that is subject to an environmental covenant. In tunij the CDPHE must review the proposed 

application and provide timely advice to the local govemment as to whether the application is consistent 

with the terms ofthe covenant or restrictive notice. 

Therefore, we respectfully request that you forward the enclosed environmental covenant to appropriate 

Lake County Departments to assist them in identifying applications that affect the land use or 

development ofthe parcels described in the covenant. 

Please don't hesitate to contact me or Doug Jamison with any questions or comments.

SOIL SAMPLING PROCEDURES 

Soil Sampling and Analysis Plan 

This attachment specifies the soil sampling procedures for purposes of terminating an 

Environmental Covenant restricting Residential Uses or other uses specified in paragraphs A.2.a 

or A.3.a of Appendix Fl. Those restricted uses are collectively referred to herein as "Uses." For 

purposes of this protocol, a "property" is defined as a portion of a claim, an individual claim or 

contiguous claims on which an Environmental Covenant restricting Uses is proposed to be 

terminated. A portion of the subject property proposed for Uses may also be subdivided for 

purposes of terminating or modifying an Environmental Covenant for only the subdivided 

portion of the property. The following sections describe the soil sampling requirements, 

methods, sample analysis, and quality assurance to support termination of the Environmental 

Covenant. Altemate soil sampling protocols and analysis methods may be proposed in a sitespecific sampling plan for the property, subject to approval by the State. 

1.1 Soil Sampling Requirements and Protocols 

Soil samples will be collected to a total depth of six inches, except in areas that are covered or 

will be covered with a minimum 2-inch thick layer of asphalt or concrete or other stmctures that 

prevent human exposure to soil, or will be covered within a minimum thickness of six inches of 

imported clean soil. Soil samples will be collected at two depth intervals: one from 0-2 inches 

deep and one from 2-6 inches deep. Each of these two soil samples will consist of a composite 

collected from three subsamples firom the same depth interval, as described in Section 1.2 below. 

Composite samples for each depth interval (0-2 inches and 2-6 inches) will be collected at four 

locations per acre, with not less than four composite samples collected for each depth interval a 

property. The composite samples will be equally spaced within the property. Each composite 

sample will consist of three subsamples of approximately equal amounts of soil collected firom 

the same depth interval. At each composite sample location, the subsamples will be collected in 

a triangular pattem with the subsamples spaced approximately five feet apart. The composite 

sample will consist of the three subsamples collected fi-om the same depth interval. 

If any deposits of mining, milling, or smelting related materials (waste rock, tailing, or slag) are 

known or suspected to be present within the property, the footprint of these areas will be defined 

as separate sampling areas not to exceed 10,000 square feet each (100 feet by 100 feet). A 

composite sample (minimum of three subsamples) will collected from the materials within each 

sampling area to a single sampling depth of 0-6 inches, or less, if the materials are shallower. 

Imported soil shall be sampled as defined below to demonstrate that the imported soil has lead 

and arsenic concentrations less than 3,500 mg/Kg and 340 mg/Kg, respectively, for Residential 

Use. 

11 
3 59747 10/1/2012 11:01 .AM Patricia Beiser 

12 of 36 COV R$202.00 DSO.OO Lake County Recorder 

Prior to soil sampling, a site sampling plan will be developed and the sampling areas and 

sampling locations will be plotted on a site plan. The site sampling plan will show the property 

boundaries and any existing residential stmctures, commercial facilities, or improvements. The 

sampling areas and sampling locations will be identified on the site sampling plan. In addition, 

any known or suspected deposits of mine, mill or smelter related materials (tailing, waste rock, 

or slag) will also be delineated on the site sampling plan with sampling locations identified. 

1.2 Soil Sample Collection and Handling Procedures 

Soil samples will be collected using a plastic or stainless steel trowel, soil probe, hand auger, 

spade or drive sampler. A pick or spade may be utilized, as necessary, to loosen the soil for 

sample collection. The specific sampling tool utilized will be dependent on the soil composition 

and density. Additional sampling equipment may include stainless steel bowls, measuring tape, 

hand-held GPS, plastic sample bags, camera, log book, pen, pencil, and marker. 

At each composite sample location, a subsample will be collected at each apex of a triangle 

spaced approximately five feet apart. At each subsample location, any loose debris and any sod 

or dense vegetation will be removed firom an area approximately six inches in diameter. Samples 

will not be collected under or immediately adjacent to trees, shmbs and or stmctures. A soil 

sample will be collected at the same subsample location to a depth of 0-2 inches and then 2-6 

inches using the sampling tool. Approximately the same volume of soil should be collected at 

each subsample location for each depth. The soil from each subsample will be collected into a 

separate clean plastic bag or stainless steel bowl for each sample depth interval. For each 

composite sample, combine the subsamples from the same depth interval together in a sealed 

plastic bag and mix by hand in the sealed bag. Label the plastic bag with the property 

identification, sampling area, depth interval, and date of collection. A chain of custody form will 

be maintained for all soil samples fi-om the time of collection until its final deposition. 

All equipment used for soil sampling will be dedicated or will be decontaminated prior to sample 

collection. Decontamination equipment will include, pump sprayers, spray bottles, deionized 

water, phosphate free soap solution, scmb bmshes, buckets, disposable gloves, etc. Field 

personnel will wear disposable polyethylene gloves to avoid sample cross contamination during 

the collection of soil samples. 

1.3 Imported Soil 

Soil imported to a property for use within the upper six inches of the final ground surface will be 

sampled to demonstrate that the lead and arsenic concentrations achieve acceptable 

concentrations for residential use and that the lead concentrations achieve acceptable 

concentrations for commercial use, as defined in Appendix Fl . For up to 1,000 cubic yards of 

imported soil delivered to a property, a sample will be collected every 250 cubic yards. For 

volumes greater than 1,000 cubic yards, a sample of the imported soil will be collected for every 

500 cubic yards. 

1.4 Equipment Decontamination 

Sampling equipment will be decontaminated between sample collection points, if the equipment 

is not disposable, in order to avoid cross contamination between samples. Field personnel will 

12 
3 5 9747 10/1/201211:01 AM Patricia Berger 

13 of 36 COV RS202.00 DSO.OO Lake County Recorder 

wear disposable gloves while decontaminating equipment. The following procedures will be 

followed to ensure that sampling equipment is decontaminated: 

1) Visually inspect sampling equipment for soil; a stiff bmsh will be used to remove 

any visible material 

2) " Wash the field equipment with phosphate free soap and water, rinse with distilled 

water, and air dry or wipe with disposable paper towels 

3) Water used for decontamination will be disposed of on site. All disposable items 

such as, paper towels, disposable gloves and wash cloths, will be deposited into a 

garbage bag and disposed of in a solid waste landfill 

1.5 Soil Sample Documentation 

Field sampling information will be recorded in a field logbook or field sampling forms. 

Information that will be recorded at each composite soil sampling location will include the 

location (e.g. determined by hand-held GPS or measured to a defined reference point) and 

sarapling depth interval. The documents to be completed for each composite sample in each 

sampling area are: 

Site Plan (Plot Plan) 

Chain-of-Custody transmittal form 

Sample tag and/or label 

Sample master log 

All pertinent sampling information will be recorded on a field logbook. Entries will be raade in 

the field documents in indelible ink, with all corrections consisting of initialed line-out deletions. 

Each day's entries will be initialed and dated at the end of each day by the field sampling crew. 

At minimum, entries in the field log shall include: 

Date and time

1.6 Soil Sample Packaging and Shipping 

Each sample container will be properly labeled in the field. All containers will be checked for 

proper seal and entered by sample number on the chain of custody form. After collection, 

composite samples will be placed in an insulated cooler for storage in the field. Samples will be 

shipped to the laboratory in a cooler with ice. The ice in the cooler will be double-bagged. One 

copy of the chain of custody form will be enclosed in a plastic bag in each cooler containing the 

samples identified on the form. The cooler will be taped shut and custody seals will be attached 

to the outside of the cooler to ensure that the cooler cannot be opened without breaking the seal. 

The cooler will be shipped using an authorized shipping service to the laboratory for analysis. 

1.7 Soil Sampling Quality Control 

Duplicate samples will be collected and subrriitted to the laboratory to evaluate the precision and 

reproducibility of sampling and analysis procedures. Duplicate samples will be collected at a 

minimum of one for every 10 soil composite samples. The duplicate samples will be collected, 

preserved, packaged, and handled in the same manner as the soil samples. No equipment blanks 

or field blanks will be collected. 

1.8 Laboratory Analytical Protocols 

The soil samples will be analyzed by the laboratory using methods detailed in Test Methods for 

Evaluating Solid Waste, Revised Methods, SW-846. The laboratory shall be accredited by the 

Colorado Certification Program. For Residential Development, samples will be analyzed for 

arsenic and lead. For Comraercial Development, soil samples will be analyzed for lead. Soil 

samples will be digested in accordance with SW-846 EPA Method 3050. After digestion, all 

samples will be analyzed by EPA Method 601 OB. 

The report of analytical results will include a cover letter from the laboratory identifying the 

sample group and any non-complaint quality control results together with the affected samples. 

Attached to the cover letter will be a summary of sample results and a summary of quality 

control results. The sumraary of quality control results will include instmment performance 

results such as standard recoveries and blanks results; matrix QC results such as spikes, 

duplicates and procedural blanks; and laboratory control standard recoveries.

TO ENVIRONMENTAL COVENANT 

GROUNDWATER SAMPLING PROTOCOLS 

Groundwater Sampling and Analysis Plan 

This attachment specifies the groundwater sampling procedures for purposes of terminating or 

modifying an Environmental Covenant for groundwater use restrictions, as specified in 

Appendix Fl . For purposes ofthe protocol, a "property" is defined as a portion of a claim, an 

individual claim or contiguous claims not exceeding 35 acres in total area for which the 

groundwater use restrictions of an aquifer are to be terminated. The followings sections describe 

the groundwater sampling requirements, methods, saraple analysis, and quality assurance that 

will support such termination or modification. Altemate groundwater sampling procedures and 

analysis raethods for a property may be proposed in a site-specific sampling plan for the 

property, subject to approval by the State. 

1.9 Groundwater Sampling Requirements 

One groundwater sample will be collected fi-om a well completed in the aquifer of the 

hydrogeologic unit (alluvial, unconsolidated sedimentary deposits, or bedrock) proposed for 

beneficial use underlying each property. For alluvial or unconsolidated sedimentary deposits, the 

hydrogeologic unit is defined as the aquifer with the same lithology and within the same surface 

water hydrologic divide. The bedrock hydrogeologic unit is defined as the aquifer within the 

same geologic formation and stmcture. The groundwater use restrictions will be terminated or 

modified for a property for only that aquifer of the hydrologic unit in which the well is 

completed. 

The groundwater saraple firom the well will be analyzed for constituents that are relevant to the 

Califomia Gulch Superfund Site for which numeric groundwater quality standards have been 

established by the State for the proposed beneficial use at the time of the application for 

termination or modification of the Environmental Covenant, ,hereafter referred to as the Numeric 

Standards. The constituents that are relevant to the Califomia Gulch Superfund Site and the 

current Numeric Standards are presented in Table 1 for drinking/domestic or agricultural uses. 

The groundwater in the aquifer will be deterrained acceptable for the proposed use, and the 

Environmental Covenant restricting groundwater will be terminated for the property or modified 

to allow a particular beneficial use, if the constituent concentrations of the sample from the well 

are less than the Nuraeric Standards for all beneficial uses (in the event of terraination) or the 

particular beneficial use (in the event of modification). 

1.10 Groundwater Sampling Methods 

The groundwater sample from the well will be collected according to the methods described in 

SOP No. 4-Ground Water Well Sampling. Non-dedicated or non-disposable sampling 

equipment will be decontaminated prior to collection of the sample according to the methods 

described in SOP No. 1-Decontamination. Sample collection documentation, sample

containment, preservation, identification, labeling and shipping will be performed according to 

the procedures described in SOP No. 7- Sample Handling, Documentation, and Analysis. 

1.11 Laboratory Analytical Methods 

Samples will be analyzed for the parameters for which Nuraeric Standards have been established 

for the proposed benefici^il use. Sample container, preservation, and holding times are provided 

in SOP No. 7-Sample Handling, Documentation, and Analysis. The laboratory will be required 

to process all samples submitted according to the specific protocols for sample custody, holding 

times, analysis, reporting and associated laboratory quality assurance. Laboratory quality 

assurance checks will include the use of blank, spiked, split, and duplicate samples, calibration 

checks, and intemal standards. Designated laboratory personnel will be required to ensure that 

QA/QC procedures are achieved. The laboratory or laboratories for constituent analysis must be 

accredited by the Colorado Certification Program. Laboratory calculations and data review will 

be performed by the laboratory in accordemce with the procedures described by the analytical 

method. The laboratory will review the results of the laboratory QC analyses, instrument 

calibration and maintenance records, calculations, and the record of sample custody (including 

holding times) within the laboratory.

DECONTAMINATION 

1.0 INTRODUCTION AND TYPES OF CONTAMINATION 

The purpose ofthis document is to define the standard procedure for decontamination associated 

with environmental investigation for the California Gulch Superfund Site. This procedure is 

intended to be used with other SOPs. 

1.1 Site and/or Sample Cross-Contamination 

The overall objective of multiraedia sampling programs is to obtain samples which accurately 

depict the chemical, physical, and/or biological conditions at the sampling site. Extraneous 

contaminant materials can be brought onto the sampling location and/or introduced into the 

mediura of interest during the sampling program (e.g., by contacting water with equipment 

previously contaminated at another sarapling site). Trace quantities of these contarainant 

raaterials can thus be captured in a sample and lead to false positive analytical results and, 

ultimately, to an incorrect assessment of the contaminant conditions associated with the site. 

Decontamination of non-dedicated or non-disposable sarapling equipraent (e.g., bailers, puraps, 

and tubing) and field support equipment (e.g., drill rigs, vehicles) is required. To ensure that 

sampling cross-contamination is prevented, and that on site contaminants are not carried off site. 

2.0 PROCEDURES 

2.1 Equipment List 

The following is a list of equipment that may be needed to perform decontamination: 

Bmshes 

Wash tubs 

Buckets 

Scrapers 

Steam cleaner or high-pressure washer 

Paper towels 

Alconox detergent (or equivalent) 

Potable water 

Deionized or distilled water 

Garden type water sprayers 

Clean plastic sheeting and/or trash bags 

2.2 Decontamination

19 of 36 COV RS202.00 DSO.OO Lake County Recorder 

2.2.1 Sampling Equipment 

The following steps will be used to decontaminate non-dedicated or non-disposable sampling 

equipment (including reusable filter apparatus): 

Personnel will dress in suitable safety equipment to reduce personal exposure (e.g., latex 

gloves, safety glasses, etc.). 

Gross contamination on equipment will be scraped off at the sampling or constmction site. 

Equipment that will not be damaged by water will be washed with an Alconox solution or 

low-sudsing detergent and potable water and scmbbed with a bristle bmsh or similar 

utensil (if possible). Equipment will be triple rinsed with potable water followed by a 

triple rinse with deionized or distilled water. 

Following decontamination, equipment will be placed in a clean area, on or in clean plastic 

sheeting to prevent contact with contaminated soil. If the equipment is not used imraediately, the 

equipment will be covered or wrapped in plastic sheeting or heavy duty trash bags to minimize 

potential airbome contamination. 

2.2.2 Submersible Pumps 

If non-dedicated submersible pumps are used they will be decontaminated between wells. The 

outside of the pump and hose will be tripled rinsed with deionized or distilled water. Deionized 

or distilled water will be pumped through the pump and hose. The volume of deionized or 

distilled water pumped through will be at a rainiraura equal to three times the volume of fluid 

that could be contained by the pump and hose. 

2,23 Water Level Probes 

Electric water level probes will be decontarainated by rinsing with deionized or distilled water or 

by wiping the probe during removal with paper towels wetted with deionized or distilled water. 

The water level probe will be placed in a plastic bag after decontamination. 

2.2.4 Sensitive Equipment 

Sensitive equipment that may be daraaged by water will be carefully wiped clean using paper 

towels and detergent water or spray bottle and towel and rinsed with deionized or distilled water. 

Care will be taken to prevent any equipment damage. 

2.2.5 Drilling and Heavy Equipment 

Drilling and heavy equipment will be decontarainated at a designated decontamination area for 

large equipment. The following steps will be used to decontaminate drilling and heavy 

equipment: 

Personnel will dress in suitable safety equipment to reduce personal exposure (e.g., gloves, 

safety glasses or splash shields, etc.).

Equipment showing gross contamination or having drill cuttings caked on will be scraped off 

with a flat-bladed scraper at the sampling or constmction site. 

Equipraent, such as drill rigs, augers, drill bits, and shovels will be sprayed with potable 

water by a high-pressure washer. Care should be taken to adequately clean the insides of 

the hollow-stera augers and backhoe buckets. 

Following decontamination, drilling equipraent will be placed on the clean drill rig and moved to ' 

a clean area. If the equipment is not used immediately, it should be stored in a designated clean 

area. 

2.2.6 Equipment Leaving the Site 

Vehicles used for non-intrusive activities shall be cleaned on an as needed basis. Constmction 

equipment such as earth moving equipment, tmcks, drilling rigs, backhoes, trailers, etc., will be 

pressure washed at the designated decontamination area before the equipraent is reraoved from 

the site. 

2.2.7 Wastewater 

Used wash and rinse solutions maybe discharged to the ground at the sampling site 

2.2.8 Other Wastes 

Solid wastes such as paper towels and used filters will be sealed in plastic garbage bags and 

disposed of in a sanitary landfill. 

2.3 Documentation 

Sampling personnel will be responsible for documenting the decontamination of sampling and 

drilling equipraent. The documentation will be recordwl with waterproof ink in the sampler's 

field notebook with consecutively numbered pages. The information entered in the field book 

conceming decontamination should include the following:

2.2 Sampling Procedures 

This section gives the step-by-step procedures for collecting samples in the field. Observations 

made during sample collection should be recorded in the field notebook and field data sheet as 

specified in Section 2.4 of this SOP. 

2.2.1 Decontaminate Equipment 

22 
359747 10/1 /2012 11:01 AM Patricia Beiger 

23 of 36 COV R$202.00 DSO.OO Lake County Recorder 

Before any evacuation or sampling begins, all well probes, bailers, and other sampling devices 

shall be decontaminated. If dedicated equipment is used, it should be rinsed with deionized 

water. Dedicated downhole pumps will not be decontaminated. A discussion of equipraent and 

personnel decontaraination is contained in SOP No. 1, Decontarainarion, and in the site Health 

and Safety Plan. 

2.2.2 Instrument Calibration 

Electronic equipraent used during sampling includes a pH meter with temperature scale, a 

conductivity meter and a turbidity meter. Before going into the field, the sampler shall verify 

that all of these are operating properly. The pH and conductivity meters require calibration and 

calibration checks every day prior to use. The turbidity meter requires a calibration check by 

reading measureraents cells of a known value. Calibration times and readings will be recorded in 

a notebook and/or on Calibration Data Sheet, which are to be kept by the field sampler. 

2.2.3 Evacuate Well 

The purpose of well purging is to remove stagnant water from the well to obtain representative 

water from the geologic formation being sampled while miniraizing disturbance to the collected 

samples. Before a seunple is taken, the well will be purged until a minimum of three well casing 

volumes have been removed and field parameters have stabilized, or until a maximum of five 

well volumes have been removed. Purging will be considered completed if the well is pumped 

or bailed dry. A well should be pumped at a rate no faster than approximately 1 gallon per 

minute if it has a tendency to dry up prior to evacuating three casing volumes. Evacuated well 

water may be disposed of at the well site in a manner that does not cause mnoff. 

Before well purging begins, the following procedures are to be performed at each well: 

Note the condition of the outer well casing, concrete well pad, protective posts (if present), 

and any other unusual conditions in the area around the well. 

If bailing place clean plastic sheeting around the well. 

Open the well. 

Note the condition of the inner well cap and casing. 

Meeisure (to nearest 0.01 foot) and record depth of static water level fi-om the measuring 

point on the well casing and indicate time. Record what the measuring point is (i.e., 

notch on north side, top of PVC well casing). 

Calculate volume of water in the well casing in gallons based on feet of water and casing 

diameter. (See Section 2.4.3 for calculation of volumes.) 

From the above calculation, calculate the three casing volumes to be evacuated. 

Obtain an initial sample (which is not retained) from the bailer or purge pump for field 

measureraents (teraperature, conductivity, and pH raeasureraents) and observation of 

water quality. 

23 
3 5 9747 10/1/201211:01 AM Patricia Berger 

24 of 36 COV R$202.00 DSO.OO Lake County Recorder 

Evacuate three volumes of water in casing with a bailer or pump. Take temperature, specific 

conductance, and pH measurements after evacuation of each well volume to confinn that 

the water chemistry has stabilized. Generally, pH values within ±0.2 pH unit and 

conductivity and teraperature readings within ±10 percent between consecutive readings 

indicate good stability of the water chemistry. If the chemistry is not stable, continue 

purging up to a maximum of five well volumes, measuring pH and specific conductance 

after each one half well volume. 

When evacuating a well using a purap, the pump intake should be placed: 

for low recovery wells (wells that can be pumped dry), place pump intake at bottom of 

screened interval. 

for high recovery wells (little drawdown with pumping), place pump at or slightly 

above the middle of the screened interval to ensure the removal of stagnant water from 

the well bore. 

If the well is bailed or pumped dry during evacuation, it can be assumed that the purpose of 

removing 3 well volumes of water has been accomplished, that is, removing all stagnant 

water that had prolonged contact with the well casing or air. If recovery is very slow, 

samples may be obtained as soon as sufficient water is available. 

2.2.4 Obtain Water Samples 

Obtain samples for chemical analysis within 2 hours after purging is completed, if possible. For 

slow recovering wells, the sample shall be collected imraediately after a sufficient volurae is 

available (water has recovered to screened interval). The water quality samples shall be taken 

firom within the well screen interval. 

The following sampling procedure is to be used at each well: 

1. Assemble decontaminated sarapling equipment. If bailers are used, new nylon or 

polypropylene rope will be used for each well for each sampling event. Assemble 

the filtering apparatus. 

2. Make sure that saraple labels have been filled out for each well. 

3. Lower the bailer slowly and gently into contact with the water in the well. Lower 

the bailer to the same depth in the well each time, within the screened interval. 

Retrieve the bailer smoothly and empty the water in a slow steady stream into the 

contaraers. If submersible or bladder pumps are utilized to collect samples, start 

the pump and fill the saraple bottles as described below. 

4. Triple rinse the saraple containers with sample water and then fill the sample 

bottles. If not enough sample water is available to perform the triple rinse, then at 

a miniraum a single rinse will be perforraed and will be recorded in the field 

logbook and/or data sheet. Cap the sample containers quickly. If sample bottles 

are pre-preserved, fill the sample bottles without rinsing. Add preservative if the 

bottle is not pre-preserved. Do not cdlow the sample containers with preservatives 

to overflow. See Section 2.2.5 for details on field filtering. 

24 
3 5 9747 10/1/2012 11:01 m Patricia Berger 

25 of 36 COV R$202.00 DSO.OO Lake County Recorder 

5. Slowly pour an unfiltered portion into the sample container for field parameter 

(pH, specific conductance, temperature, and turbidity) analyses and perform the 

in-field analyses and record. 

6. Place samples on ice in a cooler. 

7. Record time of sampling. 

8. Replace and lock well cap. 

9. Complete field documentation. 

2.2.5 Filtering Samples 

Samples for metals analyses will be filtered during the field sarapling event by using a 

disposable filter apparatus and peristaltic or hand vacuura pump. 

The following procedure is to be used for filtering: 

Assemble filter device according to manufacturer's instmctions. 

Prior to the collection of aliquots, flush the filter with approximately 100 to 200 

milliliters of groundwater. Filter saraple either by pouring saraple in the top portion of 

filter unit or pumping through an in line filter using a peristaltic purap. Saraple raay also 

be filtered by attaching the in-line filter to the submersible pump discharge. 

Triple rinse the sample containers with filtered sample water and then fill the sample 

bottles. If not enough sample water is available to perform the triple rinse, then at a 

minimum a single rinse will be performed and will be recorded in the field logbook 

and/or data sheet. Cap the sample containers quickly. If sample bottles are prepreserved, fill the sample bottles without rinsing. Add preservative if the bottle is not 

pre-preserved. Do not allow the sample containers with preservatives to overflow. 

Place the used filter merabrane or disposable filter equipment in a Ziploc® bag for 

disposal with the personal protective equipment. 

Any reusable filtering equipment will be decontaminated in accordance with SOP No. 1. 

23 Sample Handling 

Sample containers and preservatives are specified in SOP No. 7, Sample Handling, 

Docuraentation and Analysis. Saraples will be labeled and handled as described in SOP No. 7. 

2.4 Documentation 

2.4.1 Groundwater Data Sheet 

A groundwater data sheet for groundwater samples (Appendix A) will be completed at each 

sampling location. The data sheet will be completely filled in. If items on the sheet do not apply

SAMPLE HANDLING, DOCUMENTATION, AND ANALYSIS 

1.0 PURPOSE AND SCOPE 

The purpose of this document is to define the standard protocols for sample handling, 

documentation, and analysis for the Califomia Gulch Superfund Site. This procedure is 

intended to be used together with other SOPs and is referenced in all SOPs that apply to 

sarapling. 

2.0 PROCEDURES FOR SAMPLE HANDLING, DOCUMENTATION, AND ANALYSIS 

2.1 Sample Identification and Labeling 

Saraples collected during monitoring, investigations, or remediation activities will be as^gned 

unique sample identiftcation numbers. Each sample identification number will identify the 

organization collecting the sample or the program under which it is collected, sampling location, 

type of sample, and sampling sequence for each saraple. These numbers are required for 

tracking the handling, analysis, and verification or validation status of all saraples collected 

during monitoring. In addition, the sample identification numbers will be input into the project 

database to identify analj^ical results received fi-om the laboratory. 

Sample identification numbers that are assigned will be divided into four fields as shown in the 

following example: 

M-CGW 1-01-900423 

The first field is one character in length and identifies the company conducting the sampling. 

The second field is an alphanumeric code identifying the location of the sample and the last letter 

of this field indicates the matrix (e.g., CGMl indicates Califomia Gulch Well No. 1, the second 

W indicates a water matrix). The next field identified is the type of sample being collected; this 

is used to identify whether the sample is a primary or grab sample, a composite saraple, field 

duplicate, field blank, or equipment rinsate. The final field contains the date in a year-month-day 

format. For example, the sample identified above was collected on April 23, 1990. 

Each sample that is collected in the field will be labeled for future identification. Sample labels 

will be filled out as completely as possible by a member ofthe sampling team prior to the start of 

the day's field sampling activities. The date, time, sampler's signature, and the last field of the 

saraple identification number should not be completed until the sample is actually collected. All 

sample labels will be filled out using waterproof ink. At a minimum, each label will contain the 

following information:

Sampler's company affiliation; 

Site location; 

Sample identification; 

Date and time of sample collection; 

Method of preservation used; 

Sample matrix; and 

Sampler's initials. 

2.2 Sample Containers, Preservatives, and Holding Times 

2.2.1 Sample Containers 

Proper sample preparation practices will be observed to minimize sample contamination and 

potential repeat analyses due to anomalous analytical results. Prior to sampling, commerciallycleaned saraple containers will be obtained from the analytical laboratory. The bottles will be 

labeled as described in the previous section to indicate the type of sample and sample matrix to 

be collected. Sample bottles can be either pre-preserved fi-om the laboratory or preservatives can 

be added in the field during sample collection. 

2.2.2 Sample Preservation 

Saraples are preserved in order to prevent or minimize chemical changes that could occur during 

transit and storage. Sample preservation should be perforraed iramediately upon sample 

collection to ensure that laboratory results are not coraproraised by improper coordination of 

preservation requirements and holding times. Samples will be preserved immediately and stored 

on ice in coolers prior to shipping. Sample preservation requirements are based on the most 

current publication of 40 CFR, Part 136.3 and are provided in Table 1. 

2.2.3 Sample Holding Times and Analyses 

Sample holding times are established to minimize chemical changes in a sample prior to analysis 

and/or extraction. A holding time is defined as the maximum allowable time between sample 

collection and analysis and/or extraction, based on the nature of the analyte of interest and 

chemical stability factors. Holding times applicable for analytes are listed in Table 1. Saraples 

should be sent to the laboratory as soon as possible after collection by hand delivery or an 

ovemight courier service to miniraize the possibility of exceeding holding tiraes. 

For most samples, preservation by cooling to 4°C is required iramediately after collection while 

the saraples are held for shipraent and during shipment to the laboratory. 

2.3 Sample Preparation and Shipping 

After collection, samples will be labeled and prepared as described in the previous discussion, 

and placed on ice in an insulated cooler. The saraple containers will be placed in re-closeable 

plastic storage bags. Saraples will then be placed right side up in a cooler with ice for delivery to 

the laboratory. The ice in the cooler will be double-bagged. The coolers will be taped shut and 

32

.33 of 36 COV R$202.00 DSO.OO Lake Count}-Recorder 

chain-of-custody seals will be attached to the outside of the cooler to ensure that the cooler 

cannot be opened without breaking the seal. Final packaging and shipping will be conducted in i 

compliance with current lATA Resolution 618 and DOT 49 CFR Part 171 Regulations. 

All samples will be shipped for laboratory receipt and analysis within the holding times specified 

in Table 2. This may require daily shipment of samples with short holding times. 

2.4 Sample Documentation and Tracking 

This section describes the information that should be provided in field notes and saraple Chainof-Custody docuraentation. 

2.4.1 Field Notes 

Documentation of observations Emd data acquired in the field provide information on sample 

acquisition, field conditions at the time of sampling, and a permanent record of field activities. 

Field observations and data collected during routine monitoring activities will be recorded with 

waterproof ink in a permanently bound weatherproof field log book with consecutively 

numbered pages or on field data sheets as specified in the project SOPs. 

Field notebook and/or data sheet entries will, at a minimum, include the information listed 

below. Relevant SOPs should be consulted to supplement this list. 

Project name; 

Location of sample; 

Data and time of sample collection; 

Sample identification numbers; 

Description of sample (matrix sampled); 

Sample depth (if applicable); 

Sample methods, or reference to the appropriate SOP; 

Field observations; 

Results of any field measurements, such £is depth to water, pH, temperature, specific 

conductance; and 

Personnel present. 

Changes or deletions in the field book or on the data sheets should be recorded with a single 

strike mark, and remain legible. Sufficient information should be recorded to allow the sampling 

event to be reconstructed without having to rely on the collector's memory. 

All field books will be signed on a daily basis by the person who has made the entries. Anyone 

making entries in another person's field book will sign and date those entries. 

2.4.2 Sample Chain-Of-Custody 

During field sarapling activities, traceability of the saraple must be maintained from the time the 

samples are collected until laboratory data are issued. Establishment of traceability of data is 

33 
359747 10/1/201211:01 .AM Patricia Berger 

34 of 36 COV R$202.00 DSO.OO Lake County Recorder 

cmcial for resolving future problems if analytical results are called into question and for 

miniraizing the possibility of sample mix-up. Initial information conceming collection of the 

samples will be recorded in the field log book or on data sheets as described above. Information 

on the custody, transfer, handling and shipping of samples will be recorded on a Chain-ofCustody (COC) form. 

The sarapler is responsible for initiating and filling out the COC form. The COC will be signed 

by the sampler when he or she relinquishes the samples to anyone else. A COC form will be 

completed for each set of water quality samplies collected, and will contain the following 

information: 

Sampler's signature and affiliation 

Project number 

Date and time of collection 

Sample identification number 

Sample type 

Analyses requested 

Number of containers 

Signature of persons relinquishing custody, dates, and times 

Signature of persons accepting custody, dates, and times 

Method of shipment 

Shipping air bill number (if the samples are shipped) 

Any additional instmctions to the laboratory. 

The person responsible for delivery of the saraples to the laboratory will sign the COC form, 

retain the third copy of the form, document the method of shipment, and send the original and 

the second copy of the form with the samples. Upon arrival at the laboratory, the person 

receiving the samples will sign the COC form and retum the second copy to the Project 

Manager. Copies of all COC documentation will be compiled and maintained in the central files. 

The original COC forms will remain with the samples until the time of final disposition. After 

retuming saraples for disposal, the laboratory will send a copy of the original COC to the 

Operator. This will then be incorporated into the central files.

Samples requiring filtration must be filtered in the field using a 0.45 pm membrane filter before preservative is added. 

Holding times start at date of sample collection. 

Sample pH and alkalinity should be analyzed as soon as possible after collection. However, for practical purposes, the holding times have been set at seven 

days. The 14 day holding time specified In 40 CFR 136.3, Table II, is considered to be Inappropriate for the high carbonate waters ofthe system.
