This research program directly supports the Agency's Sustainable Water Infrastructure Initiative (www.epa.gov/waterinfrastructure). The outputs from this program will assist EPA's program and regional offices, states and tribes to meet their programmatic requirements and utilities to more effectively implement comprehensive asset management, provide reliable service to their customers, and meet their Clean Water Act and Safe Drinking Water Act requirements. The plan proposes, in part, work relating to demonstration and verification of condition assessment, system rehabilitation, advanced concepts and innovative treatment technologies. Proposed activities to be conducted as part of this task order address the field verification of condition assessment and rehabilitation technologies for drinking water distribution systems and wastewater collection systems. Condition assessment encompasses the collection of data and information through direct inspection, observation and investigation and in-direct monitoring and reporting (soil conditions and historical data), and the analysis of the data and information to make a determination of the structural, operational and performance status of capital infrastructure assets. Research issues in this area relate to the collection of reliable data and information and the ability of utilities to make technically sound judgments as to the condition of their assets. Condition assessment also includes the practice of failure analysis which seeks to determine the causes of infrastructure failures in order to prevent future failures. System rehabilitation is the application of infrastructure repair, renewal and replacement technologies in an effort to return functionality to a drinking water or wastewater system or sub- system. The decision-making process for determining the proper balance of repair, renewal and replacement is a function of the condition assessment, the life-cycle cost of the various rehabilitation options, and the related risk reductions.

Grouts can be used for controlling leaks in th e wastewater facilities and repairing the cracked concrete. T he CIGMAT studies have been focused on (1) testing and ch aracterizing the fl ow properties and setting tim e of cement and polymer grouts, (2) behavior under various chem ical exposure, and (3) bonding strength of concrete repairing grout materials. 1.2 Technical Approach The overall objective of this test plan is to develop a testing program to systematically evaluate grouts for controlling infiltration to wastewater systems and leaks in concrete structures. Specific test plan objectives are to: • Evaluate properties (working, physical, mechanical, durability, and leaching) of grouts; • Characterize the bonding properties of the grout-substrate interaction; and • Verify the perform ance of grouted joints a nd repaired concrete cracks under hydrostatic pressure up to 5 psi (about 10 feet of wate r) and wet/dry cycles over a period of one month. Testing will use relevant ASTM and CIGMAT st andards. A total of 10 different tests will characterize the g routs (Table 3 -1), and sev eral addition al tes ts will evalua te g rout-substrate interaction (Table 3-2). Model test will be used to evaluate grout effectiveness for concrete repair for leak control. All CIGMAT standard methods referenced herein are included in Appendix A. 1.3 Test Plan Schedule and Milestones The tests described herein will be completed within six months from the start date.

Grout viscosity will be evaluated using a procedure outlined in CIGMAT GR 6-02. Using a cylindrical spind le- type viscom eter (Brookfield Viscom eter with 8 speeds, LVT m odel with four spindles or equivalent), the initial viscosit y and changes in viscosity duri ng the gelling pr ocess shall b e measured at room temperature at selected strain rates (up to 180 sec "1). The specific strain rates at which viscosity will be measured shall be determined in advance of testing by the TO, with the consent of the vendor. Once the material perform s consistently at differe nt viscometer speeds, the test shall be complete. A minimum of three replicate tests shall be conducted. 3.1.2.2 Setting (Gel) Time Grout setting or gel time will be ev aluated using the procedures described in this s ection. The gel time for the grouts s hall be determined by the elapsed time from grout preparation until the grout no longer flows from a plastic cup or beaker inclined slowly (so that if the cup/beaker were filled with liquid, the surface of the liquid would remain level) to 45 degrees. Approximately 50 mL of freshly prepared grout shall be poured into a container. The analyst shall tilt the cup to 45° to horizontal and record the tim e for the grout to gel, as indicated by it no longer exhibiting liquid flow properties and no longer flows from the container. A total of six replicates of each grout shall be analyzed. 3.1.3 Physical and Mechanical Properties To obtain initial ch aracterization infor mation on the grout speci mens, all specimens shall be weighed to 0.1 g using a calibrate d digital balance and m easured (diameter and height) using a vernier caliper with a least count of 0.1 mm. Measurements shall be taken at the top, middle, and bottom oft he specimen, with two m easurements taken at 90 degrees from each other at each location to obtain consistent data. 3.1.3.1 Unit Weight (Density) Solidified grout specimens shall be used to determine the unit weight (density) of the grout. The determination shall be com pleted per CIGM AT GR 1-00 for both grout and grouted sand specimens. Unit weight shall be calculated us ing the weight and volum e of the specim ens. A minimum of three rep licates will b e evaluate d for unit weight. Based on the unit weight, the grout shall be reported as lighter or heavier than water. 3.1.3.2 Water Absorption Water absorption characteristics shall be evalua ted on grout specim ens as outlin ed in standa rd procedure CIGMAT 3-00. A m inimum of three solidified grout specimens shall be immersed i n tap water (initial pH in the range of 7 to 8) and changes in weight and volum e (determined by measuring specimen diameter and height) of the specimens shall be recorded a minimum of once Warren Environmental Grout Test Plan - v3.2 Page 20 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION every working day (Monday through Friday, excluding holidays) until the changes in weight and volume become negligible (less than 0.5 percent of the previous weight and volum e), or for one week, whichever occurs first. The report for this testing shall include the tim e of immersion, the initial cha racteristics of the spec imens, the weight and volum e change with tim e, water absorption as a percentage of the initial weight, and volume of grout. 3.1.3.3 Shrinkage The Vendor selected 23°C for this test to be com pleted, representing a clim ate between the extremes indicated in the Protocol (10°C and 27°C) . At the onset of the test, specimens shall b e prepared in a mold with inner dimensions of 1.5 in. (38 mm) in diameter and 3.5 in. (90 mm ) in length. Three specimens shall be tested under the selected test conditions. The specimens shall be placed in zip lock bags and kept at conditions indicated in Table 3-3. Humidity will be measured using a dig ital humidity meter. The weight and dimensions of the specim ens shall be reported before and after 28 days of conditioning. Table 3-3. Shrinkage Test Conditions Parts Temperature, Duration, and storage condition PartC 23°C ± 2°C for 28 days in zip lock bags (RH = 90%+ 5%) 3.1.3.4 Permeability Solidified g rout spe cimens shall be used to determine their perm eability. Specim ens shall b e prepared in 1.5-in. diam eter Plexiglas/gla ss cylinders and perm eated with water under a hydraulic gradient of 100, per C IGMAT GR 7- 02. Testing shall be com pleted at room temperature and hum idity. A m inimum of three replicate tests shall be run on the grout specimens. The report for this testing shall include the temperature and humidity at which testing was completed, any changes in the specim ens during the testing, and th e permeability obtained during the testing. 3.1.3.5 Unconfined Compressive Strength and Stress/Strain Relationship CIGMAT GR 2-02 has been developed for test ing grouts in com pression under m onotonically increasing load (load increasing linearly). Compression tests shall be performed using screw-type machines with capacities up to 5,000 Ibs. Specim ens shall be loaded at sp ecified rates based on the type of grout and the loading rate may be determined based on trial tests conducted outside of this tes ting. Specim ens shall be te sted in dup licates at intervals of 3 and 28 days following specimen preparation, as described in CIGMAT GR 2-02. The reported data shall include compressive strength, modulus and failure strain, where the m odulus is determ ined from the initial slope of the stress/strain relationship and the failure strain is the m aximum loading point before the specimen fails. Warren Environmental Grout Test Plan - v3.2 Page 21 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION 3.1.3.6 Tension Tests The tension test indicated in the Protocol will not be completed during this verification, as the bonding test (described in Section 3.2) will prov ide the information regarding the grout's ability to withstand tensile loading. The key perfor mance indicator for the grout m aterial under tension is to show it does not fail before the bond with the substrate, which will be determined during the bonding test. Since this test can be done on som e grouts and no t the others, we should delete it from the test protocol to be fair to all the materials being tested. 3.1.4 Durability Properties 3.1.4.1 Wet/Dry Cycle During its service life, the grout could be subjecte d to a nu mber of wet/dry eye les. This tes t is designed to determine the impact of repeated wetting and drying on the performance of grouts. A minimum of three replicate specim ens shall be used for this tes t. The specim ens shall b e subjected to 10 wet/dry cycles for a total test ti me of 140 days, or until failure (uncon solidation). One wet/dry cycle shall be 14 days in duration, consisting of 7 days of water exposure followed by 7 days of dry conditions at ro om temperature and humidity (23 + 2°C and 50% + 5% RH). The water exposures shall be com pleted as described in Section 11 of CIGMAT GR 3-00, using tap water having a pH between 7 and 8. Change s in length, diameter, weight, and volume of the specimens shall be measured daily per Sections 9 and 11 of CIGMAT GR 3-00. At the end of the 10-wet/dry cycles, specimens shall be tested to determine the compressive strengths of the grout, as described in sections 3.1.3.5. T he reported data sh all include weight and dim ension data collected for the specimens, as well as the data to be reported described in sections 3.1.3.5. 3.1.4.2 Chemical Resistance This test will evaluate the resistance of grouts when exposed to chemical conditions representing various sand and groundwater environm ents. The te st results will help when selecting suitab le grouts for use in various chem ical environments. Cylindrical grout specimens shall be prep ared as described in Section 3.1.1.1, and the initial wei ght, dimensions, color, and surface appearance of the specim ens shall be recorded . Three specim ens at each pH shall be fully immersed in solutions with pH 2, 7, and 10 maintained at room temperature (23 + 2°C) for the entire exposure period. The solutions shall consist of tap wate r with hydrochlo ric acid or sodium hydroxide added to achieve the pH required for the test s. The weight, volum e, color, and surface appearance of the specim ens shall be determ ined and reco rded for three specim ens at each p H after 30, 90, and 180 days, as described in Se ction 7.3 in CIGMAT CH 2-01. The pH, clarity, and color of the exposure solution shall also b e recorded at each evaluation tim e. During the evaluation, if the pH ch anges by more than ± 2 units, addition al hydrochloric acid or sodium hydroxide shall be added to the solution to return it to its original pH. Th e analyst shall note in the project logbook the quantity of chem ical and revised pH during each adjustm ent. After each evaluation, compression testing shall be completed for the specimens in accordance with Section 7.4 of CIGMAT CH 2-01. All data and observa tions shall be reported, along with the Warren Environmental Grout Test Plan - v3.2 Page 22 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION calculations described in sec tions 8.1, 8.3, and 8.4 of CIGMAT CH 2-01. The appearance of specimens and immersion solutions shall be re ported as described in sections 9.2 and 9.3 of CIGMAT CH 2-01. 3.1.5 Environmental Properties—Leaching Test Potential co ntaminant leaching fro m solidified grout shall be determ ined by analyzing water exposed to the grout. T he protocol calls for an alysis of the exposure water for total organic carbon (TOC) and lead. Lead is an issue only with inorganic materials, which is not the case with the epoxy grout in this test. Subsequently, the exposure water will be evaluated only for TOC. A minimum of three test replicates, using cylindrical grout spec imens, will b e prepar ed a s described in Section 3.1.1.1. The specimens will be immersed in three individual exposure jars, each containing tap water (pH = 8 ± 0.5; TOC < 1 mg/L). One blank container con taining only the exposure water shall be prepared and he Id under the sam e condi tions as the specim en exposure jars. The exposure jars and blank jar will be held at room temperature for seven days. The test shall be conducted with grout specim ens and water volume so that there is an adequate volume of e xposure water to conduct the required analyses. A liquid-to-s olid ratio of 1:1 (by volume) will be usedj. If a d ifferent liquid -to-solid ratio is used, it shall be reported in th e verification report. At the beginning and end of the exposure period, samples of the exposure water will be analyzed to determine the presence of organic com pounds that have leached from the grout. The samples will be analyzed for TOC. The water in the blank container shall be sa mpled at the beginning a nd end of the exposure period, and analyzed for the sam e constituents as the grout specimen exposure water. This will provide a baseline concentration of constituents in the tap water. Details of the analytical m ethods, required sample volumes, and sample holding are provided in Section 4. 3.2 Grout-Substrate Bonding Strength Interaction between the grout and a concrete su bstrate shall be evaluated by testing the bonding strength and type of failure (bond ing failure, substrate failure, or a combination) under different service conditions, as specified in sections 3.2.1 through 3.2.3. Testing of wet grout/concrete substrate specimens shall be conducted over a period of six months in accordance with CIGMAT GR 5-00 (where two cylinders are bonded with grout) or CIGMAT CT 3-00 (where the area between concrete prisms is grouted), as select ed by the vendor prior to the ETV verification. In addition, bonded configurations prepared according to either CIGMAT GR 5-00 or CIGMAT CT 3-00 shall be subjected to wet/dry cycle testing, as described in Section 3.1.4.1. Warren Environmental Grout Test Plan - v3.2 Page 23 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION 3.2.1 Cylinder Bonding (CIGMAT GR 5-00) This test configuration may be used to determine the bonding strength of various grout materials (15,23). The test consists of sandwiching a layer of grout between flat surfaces of concrete (the ends of concrete cylinders) a nd then loading the test specim en in tension. Details of specim en preparation are in CIGMAT GR 5-00. The Grout-Rock Test outlined in Section 7.2 of CIGMAT GR 5-00 will not be conducted as part of this testing. The reported data shall include all collected data, the bonding strength, and the type of bonding failure. 3.2.2 Concrete Prism Bonding (CIGMAT CT 3-00) Although CIGMAT CT 3-00 was developed for coatin g materials, it may be adopted for grouts. As described in CIGMAT CT 3-00 , the grout shall be sandwiched between a pair of rectangular concrete prism specimens and then tested for bo nding strength and type of failure. Even though CIGMAT CT 3-00 specifies the use of dry prism s, for the purposes of ETV t esting, wet specimens shall be used to sim ulate extr erne grouting conditions. The bonded wet specim ens shall be imm ersed in water until testing begins. The reported da ta shall include the num ber of specimens tested, age of specim en at time of test, average bond strength, st andard deviation and type of failure. 3.2.3 Wet/Dry Cycle During its service life, a grouted concrete joint could be subjected to a number of wet/dry cycles. Hence, each bonded configuration will be tested for performance by subjecting it to 10 wet and dry cycles, where one wet/dry cycle takes 14 days , for a total test tim e of 140 days, or until failure. Following the wet/dry cycles, a m inimum of three test specim ens shall be re tested to determine the bonding strength, per Section 3.2.2. 3.3 Model Tests The model test is to simulate field conditions. Vendor has selected Model Test 4 for Concrete Repair for this verification. 3.3.1 Model Test 4: Concrete Leak Repair In order to simulate a leak in a concrete structure, this model test (Figure 3-2) shall use 10 in (25 cm) diameter circular concrete disks with 6 in (15 cm) openings at the center (so that each disk is donut shaped). As a default, the two disks shall be placed 1 inch apart and grouted by the vendor. The vendor m ay, however, select the opening size. The grouted joint shall be subjected to hydrostatic pressure testing to determine the leak rate, as detailed in 3.3.5. Procedure for preparing the concrete leak repair joint for Model Test 4: • The gap between the concrete rings on the testing rig shall be one inch. • The vendor shall apply the grout in the gap in accordance with the vendor's standard procedures. Warren Environmental Grout Test Plan - v3.2 Page 24 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION After the grout has cured, testing will commence using the procedures outlined in Section Supporter Concrete Ring steel Pipe a) Elevation View Grout 10' b) Plan View Figure 3-2.

Warren Environmental Grout Test Plan - v3.2 9/14/2009 Page 25 of 42 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION 3.3.2 Model Test Procedures The testing procedure will b e conducted in duplicate. The grout shall b e applied by the vendor. CIGMAT personnel shall supervise the grouting procedures and pict ures shall be taken of the joint/concrete disks prior to and after grouti ng. The tim e elapsed and volum e of grout used during the grouting process shall be recorded. During the grouting of the simulated crack, at least ten grout samples shall be collected to test the setting time (Section 3.1.2.2), unit weight (Section 3.1.3.1), and com pressive properties (Section 3.1.3.5) of the grouts. These analyses are in addition to those specified in Section 3.1. Once the grouted crack is cured per the manufacturer's instructions, they shall be subjected to the following regimen: 1. Apply hydrostatic pressure of 3 psi and hold for 5 m inutes; then m easure the leak rate using a graduated cylinder and a stopwatch. 2. Repeat Step 1 at a hydrostatic pressure of 4 psi. 3. Repeat Step 1 at a hydrostatic pressure of 5 psi. 4. Maintain saturated conditions for a period of one week. In model test 4, soak the joint with water for a week. 5. Drain all water from the test chambers and allow them to stand for one week. 6. Repeat Step 4. 7. Repeat Step 5. 8. Determine leak rates as described in steps 1 through 3 after a month of test.

Careful adherence to these proce dures will ensure that th e data generated from the testing will p rovide sound analytical results th at will indicate th e true p erformance of the grout, and form the basis for the report on the testing. 5.1 Quality Assurance Responsibilities The TO, in preparing the test pi an, shall be responsible for ensu ring that the test plan and the QAPP properly implement the requirements of this test plan. The VO is responsible for review of the test plan to assure that all elements required by this test plan are properly addressed. During testing, the TO shall be responsible for a ssuring that the elem ents contained in the test plan are complied with. Written or electronic records shall be maintained for calibrations, sample collection, and data m anipulation. In grout testing, sources of e rror may include instrum entation drift or m iscalibration; variatio ns in the grout, sand, and/or s ubstrate; system atic bias of measurements; and /or intr insically inac curate ins truments. The quality of ref erence measurements is ensured by frequent ins trumentation calib ration in accordan ce with th e manufacturer's instructions. The TO shall maintain documentation of instrument calibration. 5.2 Data Quality Indicators The data obtained during verification testing must be sound for accurate conclusions to be drawn. For all m easurement and monitoring activ ities conducted for grout verification, the VO and EPA require that the data quality parameters be established based on the proposed end-users of the da ta. Data qua lity parameters include four indicators of data qua lity: representativeness, completeness, precision, and accuracy. 5.2.1 Representativeness Representativeness refers to th e degree to which data accurate ly and prec isely r eflect th e conditions or characteristics of the parameters and will be ensured by consistent data acquisition and sam pie collection (including sam pie numb ering, tim ing of sa mple collection, sa mpling procedures, sample preservation, sample packaging, and sample shipping). Using each method at its optimal capability to provide the most accurate and precise m easurements possible will als o ensure representativeness. Representativeness also implies collecting sufficient data during each operation to be able to detect changes in ope ration. The following actions will be taken to achieve this: Test Materials: • Test Concrete: The test concrete batch shall be rejected if the unit we ight and/or water absorption properties exceed ±20% of the mean values. Warren Environmental Grout Test Plan - v3.2 Page 28 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION Laboratory Conditions: • Temperature and Humidity : For those tes ts where te mperature and hum idity requirements are specified, tern perature and humidity readin gs shall be recorded daily to ensure that laboratory conditions have not changed. Equipment: • Proper operation: This shall be verified every morning of active testing. 5.2.2 Completeness Completeness refers to the am ount of data coll ected from a m easurement process com pared to the expected amount to be obtained. For this te st plan, completeness refers to the proportion of valid, accep table data generated using each method. The com pleteness objective for data generated following this test plan is 85%, as calculated by Equation 5-1. (n \ Completeness = vaM and acceptMe x 100 (5-1) I "total ) 5.2.3 Precision Precision refers to the degree of mutual agreement among individual measurements and provides an estim ate of random error. An alytical precision is a m easurement of how far an individual measurement may deviate from a mean of repli cate measurements. Precision is ev aluated from analysis of field and laboratory duplicates and spiked duplicates. Duplicates will be collected at a frequency of one duplicate for every ten sam pies collected for the laboratory analys es discussed in Chapter 4. The labo ratory will r un duplicate samples as part of its QA program. The data quality objective for precision is based on the type of analysis performed. The stand ard devia tion (SD), r elative stand ard deviation (RSD), and/ or relative percent difference (RPD) recorded from sample analyses are ways to quantify precision. SD is calculated by: Standard Deviation = , Where: x = sample mean x; = /'th data point n = number of data points Warren Environmental Grout Test Plan - v3.2 Page 29 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION Relative percent difference (RPD) is calculated by: C -C *~i *-: RPD = =-^- x 100% (5-3) C \ / Where: Cv = Concentration of the compound or element in the sample C2 = Concentration of the compound or element in the duplicate C = Arithmetic mean of the sample and the duplicate As specified in Standard Methods (Method 1030-C), precision is specified by the standard deviation of the results of replicate analyses. For the various tests to be conducted by CIGMAT at its testing facility, precision will be measured by performing duplicate tests and evaluating the resultant data by calculating the SD, RSD, and RPD. Ta bles 3-1, 3-2 and 4-1 provide the required number of duplicate tests for the various testing methods. In situation s where th e tes ting procedures sp ecify precision objective s (such as ASTM or Standard Methods), the specific precision objectives must be achieved in order for the test to be considered valid. For o ther situations where sp ecific precision objectives are not required, the precision values shall be reported in the verification report. 5.2.4 Accuracy For measurements that will be reco rded as part of this study, accuracy refers to the difference between the m easured reading and an establish ed reference. In order to report accuracy, the instruments used during testing shall be calibrate d as required by the analytical m ethod, and the calibration records, which are m aintained as a ha rd copy m aintained in the laboratory, shall be made available. Spiking a sam pie m atrix with a known am ount of a con stituent and m easuring the recov ery obtained in the analysis is a m ethod of dete rmining accuracy. Using laboratory perform ance samples with a known concentratio n in a specific m atrix can also m onitor the accuracy of an analytical method for m easuring a constituent in a given matrix. Accuracy is usually expressed as the percent recovery of a com pound from a sample. The following equation will be used to calculate percent recovery: Percent Recovery = [(AT - A;) / As ] x 100 (5-4) Where: AT = Total amount measured in the spiked sample A; = Amount measured in the un-spiked sample As = Spiked amount added to the sample Warren Environmental Grout Test Plan - v3.2 Page 30 of 42 9/14/2009 ------- EPA STREAMS 61/ETV WATER QUALITY PROTECTION CENTER VERIFICATION During verification testing, the labo ratory will run matrix spike samples at a f requency of one spiked sample for every 10 samples analyzed. The laboratory will also analyze liquid and solid samples of known concentration as lab control samples. 5.2.5 Measurements Leaks in the model tests will be measured accurate to ± 2 mL. The weight and dim ension during the grout te sts will be m easured to an accurac y of 0.1 g and 0.1 mm, respectively. The unit weight and strength will be measured to an accuracy of 0.5 Ib/ft3 and 2 psi, respectively. 5.2.6 Analytical Quality Control The quality control procedures for blanks, spikes, duplicates, calibration of equipment, standards, reference ch eck sam pies and other quality cont rol m easurements will f ollow the guidance of EPA methods and CIGMAT SOPs. Table 5-1 s hows the quality control lim its that will be used by the laboratory for th ese analyses to ensu re compliance with the data quality in dicators for accuracy and precision. Field and laboratory duplicate analyses will be performed at a frequency of one duplicate per ten samples collected. Samples will be spiked for accuracy determination at a frequency of one per 10 sam pies analyzed by the laboratory. Accuracy and precision will be calculated for all data using the equations presented in sections 5.2.2 and 5.2.3. Table 5-1. Summary of Analytical Accuracy and Precision Limits Analysis Accuracy (% recovery) Precision (RPD) TOC 80-120 0-20 Note: If a dditional analytical parameters are adde d to the testing procedures, accuracy and precision limits shall be specified in the test plan.
