Proposed points are subject to change due to dynamic decision making in the field based on live HRSC data. O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 911 of 36 P a g e | 10 TECHNICAL APPROACH AND SCOPE OF WORK Technical Approach Eagle Synergistic will supply a team of HRSC specialists and a command center vehicle, which will house all applicable technologies and equipment. Eagle Synergistic command center vehicles will come equipped with multiple backup probes, trunklines and replacement parts. Two probes, trunklines and tool strings will be prepared at all times, allowing for efficient equipment changes. Subsurface imaging will begin using the membrane interface probe (MIP) coupled with an electrical conductivity dipole (EC) and a hydraulic profiling tool (HPT) system, collectively known as the MIHPT. This probe is a logging tool that indicates volatile hydrocarbon and solvent contamination in addition to soil electrical conductance and indicators of formation permeability. An inert carrier gas is continually swept behind a heated membrane in the probe, delivering diffused VOC’s to a series of detectors at the surface. The detectors each respond to different analyte properties, which allow Eagle Synergistic specialists to discern the contaminant to its family group, as well as provide the ability to map out the contaminant plume from source to extent. Obtaining an understanding of lithological and hydrogeological data, along with the contaminant information, allows us to determine if contamination is near to prominent migration pathways or bound up in a storage zone. Eagle Synergistic exceeds Geoprobe's guidelines and SOPs for quality control before and after every boring. For the MIHPT, we will perform response tests using a site-specific contaminant with a range of concentrations to demonstrate detector, probe, and trunkline effectiveness and accuracy. Additionally, we will test the EC sensor using a current resistor with known high and low values. The HPT sensor and screen are tested using the HPT reference tube which confirms the sensors ability to accurately measure pressure differentials. These tests can be printed out and are available as part of the final data package if requested. Eagle Synergistic Optimizing Technologies plans to work with a reputable and approved direct push provider. The DPT Provider will be responsible for advancing Eagle Synergistic’s subsurface imaging probes, as well as for confirmation sampling. Scope of Work Eagle Synergistic will mobilize to Austin, TX from our location in Austin. Eagle Synergistic specialists will perform QC checks on all equipment prior to the project start date to ensure that applicable equipment is ready for advancement. We will begin using our MIHPT system at predetermined locations. Subsequent HRSC borings will be placed at planned locations, or at a new location based on real-time HRSC data. This dissolved phase contamination, lithology, and hydraulic conductivity data can be instantly utilized by field personnel in order to determine the next boring locations. This approach to HRSC investigations allows a high level of dynamic decision making, leading to the most efficient characterization of the site. • Proposed approximately 15 MIHPT borings to 20’ bgs. • Proposed scope will take approximately 3 days of onsite operations. • Client goals are to investigate near MW-6 and delineate the southeastern side of the site. • Our first borings will be near the MW-6 as identified by client’s previous groundwater and soil sampling data. • Client will work with HRSC team to dynamically make decisions on subsequent HRSC borings to assist with delineating the plume and/or source. O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 912 of 36 P a g e | 11 • MIHPT borings placement will be determined based on the historical data per client and dynamic decision making between client and Eagle Synergistic. • Client will notify Eagle Synergistic if potholing and/or concrete coring will be required for each boring. • Eagle Synergistic will collect GPS coordinates for HRSC borings only if requested by client. • If applicable, Eagle Synergistic will work with client and DPT Provider to select discrete, confirmatory soil and/or groundwater sample locations and intervals. Lab analytical data is handled entirely via the client. Eagle Synergistic anticipates that we will have the ability to complete approximately 150-200 feet of MIP borings per day. These estimations are lithology and site dependent. This also assumes that weather conditions and other factors are favorable. Eagle Synergistic’s goal is to assist in understanding the HRSC data gathered. Our field specialists will work with field scientists to understand the live data as it is acquired. We will also be working virtually with CR Solutions to assist with interpretation and making important decisions regarding the placement of further points. Our clients not only receive consistent daily communication, but also receive detailed daily reports. This report will include all preliminary data, including footage, field notes, boring locations completed, and individual logs. Final logs and a comprehensive report, which will include overlays and cross section views, will be provided after project completion. After receiving the final comprehensive report, our technical team will contact you to discuss and/or present the HRSC data. If 3D modeling is requested, Eagle Synergistic will begin processing the data once HRSC activities are completed. We are always available to answer any questions that may arise.

If requested, Eagle Synergistic will develop a site-specific health and safety plan (HASP) before the scheduled start of the project. CR Solutions and/or DPT Provider are responsible for obtaining and verifying utility locates. Eagle Synergistic may request copies of locates from CR Solutions and DPT Provider. All Eagle Synergistic employees assigned to the project will be thoroughly informed regarding the scope of work and site-specific hazards. Daily tailgate meetings will be held to discuss and inform all personnel of job-related hazards. If applicable, the finalized HASP will be sent to CR Solutions for approval upon request. Thorough SOP’s for the safe use of HRSC technologies have been developed, and all field personnel have been trained on their use. Copies of these SOP’s are in all field vehicles for employee reference. SDS’s for all utilized chemicals are also located in field vehicles, and Eagle Synergistic personnel will be thoroughly trained on the health risks of contaminants specific to the site prior to the commencement of work. Our employees receive regular, industry-leading safety trainings. Without exception, all employees have up-to-date HAZWOPER 40-hour certifications. Red Cross First Aid, CPR, Basic Safety Plus, and site- specific safety trainings have been completed by key HRSC specialists. Eagle Synergistic also conducts in-house monthly safety training meetings. At a minimum, Eagle Synergistic employees are always required to wear Level D PPE on-site. Eagle Synergistic field employees are trained on the proper use of PPE and these items are regularly inspected to ensure that they are in good condition. PPE can be added for sites requiring greater protection than Level D. On sites requiring the use of respirators, all field employees will have active respirator fit tests. Eagle Synergistic participates in and complies with safety and risk management programs such as Avetta® and ISN® Networld. All employees are randomly tested under the DISA program. Copies of all Eagle Synergistic safety documents and programs are available to our clients upon request.

A heated probe carrying a semi-permeable membrane is advanced to depth in the soil. VOCs in the subsurface diffuse across the membrane, enter a carrier gas stream, and are swept to gas phase detectors within the HRSC Command Centers for measurement. MIP Principles of Operation The MIP is a screening tool with semiquantitative capabilities acting as an interface between volatile contaminates at depth in the soil and gas phase detectors at the surface. The MIP membrane is semipermeable and is comprised of a thin film polymer impregnated into a stainless steel screen for support. The membrane is approximately 6.35mm in diameter and can be easily replaced. The membrane is placed in a heated block attached to the probe. This block is heated to approximately 100-120 degrees Celsius as the probe is advanced into the soil. Heating the block accelerates analyte diffusion across the membrane while at the same time minimizing membrane absorption. Diffusion across the membrane is driven by the concentration gradient between the contaminated soil and the clean carrier gas behind the membrane. A constant gas flow of 35-45 mL/min sweeps behind the membrane and carries the contaminants to the gas phase detectors at the surface. Travel time from the membrane interface to the detector(s) is approximately 30-60sec (depending on the length of trunkline and flow rate). O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 916 of 36 Detector Array P a g e | 15 Our MIP detector system utilizes three detectors: an XSD (halogen specific detector, A), FID (flame ionization detector, B), and a PID (photoionization detector, C). Each of these detectors respond to different traits of an analyte and the combination of all three provides the investigator with the ability to discern between typical contaminant types such as hydrocarbons and chlorinated solvents, even when comingled. Halogen Specific Detector (XSD) The XSD operates in an oxidative state that converts halogenated organics into free halogen atoms. These halogen (X) atoms are adsorbed onto the activated platinum surface of the detector probe assembly resulting in an increase thermionic emission. This emission current is comprised of free electrons, and negative and positive ions which provide a corresponding voltage that is measured via an electrometer circuit in the detector controller. The XSD is a destructive detector used for the detection of total halogenated VOCs in the MIP system. O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 917 of 36 P a g e | 16 Flame Ionization Detector (FID) The FID uses a hydrogen/air flame to produce ions and electrons that can conduct electricity through the flame. A potential is applied across the burner tip and the collector electrode. The resulting current is then amplified and recorded. The FID will respond to any VOCs at a high enough concentration. The FID has a lower sensitivity to common VOC analytes than other detectors and typically serves as a confirmation detector run in tandem with the PID and XSD however it is the primary detector for mapping methane impacts since it does not show up on the other detectors. Photo Ionization Detector (PID) The PID uses ultraviolet radiation to ionize molecules in the effluent of the MIP carrier gas stream for analyte detection. The PID is a non-destructive detector and can therefore be used in series with other detector types. For a compound to be detected by a PID the chemical must have an ionization potential below the electron voltage of the PID lamp. The most common PID lamp used with the MIP is 10.6eV. The PID is generally used for detection of aromatic hydrocarbons such as benzene and toluene and double bonded chlorinated compounds such as trichloroethylene and perchloroethylene. O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 918 of 36 P a g e | 17 EC Principles of Operation The electrical conductivity measurement is accomplished by using a dipole measurement arrangement at the end of the MIP and the OIP probe. The field instrument induces a current across the electrical dipole and probe shell as it penetrates the soil. The system measures electrical current and voltage and from these parameters can calculate electrical conductivity. Higher electrical conductivity is typically representative of finer grained sediments, such as silts and clays, while sands have distinctively lower conductivities. Ionic contaminants in the soil or pore fluids will increase the measured conductivity. This enables mapping of salt and brine contaminant plumes. Interpretation of electrical conductivity (EC) logs comes with field experience. It is very important that soil core samples are taken to confirm lithologic changes as each EC log is unique per site. As a generalization, a high conductivity reading indicates a smaller grain size, and a low conductivity reading indicates a larger grain size When possible, it is recommended to run the EC in conjunction with the HPT. In general, both detectors should trend together, confirming the collected lithological and hydrogeological data. An additional benefit of running both detectors together is that if one of the two is rendered ineffective due to site-specific geological conditions the other detector can still be used to gain valuable subsurface information.

Measurement of the injection pressure in the HPT system is made using a downhole pressure transducer (E). Use of a transducer in the downhole position allows measurement of the injection pressure at the HPT screen only and excludes frictional the HPT losses through the trunkline. The downhole transducer position is also necessary for making hydrostatic pressure measurements at the probe. The HPT system can: flow tube of • Produce a detailed log of relative formation permeability • Be used to estimate hydraulic conductivity in the saturated zone • Logs HPT injection pressure, flow rate and electrical conductivity • Use pressure dissipation tests to measure hydrostatic pressure • Determine piezometric profile and water table depth EC (Grain Size Indicator) HPT Pressure HPT Line Pressure HPT Flow Abs. Piez. Pressure Tight clay interval Sandy interval Silty sands High permeability Groundwater table Dissipation test High transmissivity zones Est. K The HPT system adds the following datasets, from left to right: electrical conductivity, HPT pressure, HPT line pressure, HPT flow, absolute piezometric pressure and estimated K values. The HRSC signatures are helpful indicators for contaminants, lithology, and hydrogeological properties. O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 920 of 36 P a g e | 19 CONFIRMATION & CORRELATION (OPTIONAL) Pending client discussion, Eagle Synergistic recommends collection of physical confirmation soil and/or ground water samples from 10-20% of HRSC borings. High resolution sampling at numerous borings enhances the ability to make the HRSC data semi-quantitative. At each offset boring, our HRSC Specialists will make recommendations for vertical, high resolution, physical sampling, correlated with HRSC signatures. If desired, discrete groundwater sampling can be performed using the Discrete Groundwater Sampling Profiler, Groundwater Sampler, or the Screen Point 16 Groundwater Sampler (SP16) probe. 1.75” Ground Water Sampler This tool utilizes 1.75” rods to advance the probe into the subsurface. Attached to the probe are two .25” water lines, (specialized tubing for PFAS sites). One tubing line is an injection line providing a consistent flow of DI water in order to provide the HPT data. The other line is a sample line which has a mechanical bladder pump attached to it that will pump the discrete water samples to the surface. DI water is then utilized to purge the sample line before advancing further to obtain additional samples. Specific conductance meters are utilized to confirm formation water or DI water. In addition to sample collection, this tool has the ability to: • Produce a detailed log of relative formation permeability • Log HPT injection pressure, and flow rate HPT Pressure HPT Flow Low permeability, resulting in low yields -High permeability -Within groundwater table -Resulting in high yields O: 303-305-7783 | www.EagleSynergistic.com | D: 720-475-0022 13 C14-2025-0090 - West Martin Luther King Jr Blvd and Nueces Street; District 921 of 36 Project Assumptions P a g e | 20 All affiliated parties on site will abide by established safety protocols. • • Work can be completed during daylight working hours, unless otherwise specified. • • • • • • • • • • • • • • • • • • • • • Eagle Synergistic will directly contract the DPT provider specifically for advancing HRSC tooling; and will assist with communications and logistics. Eagle Synergistic will directly contact the DPT provider for necessary materials and ancillary items only within the attached/included quote. All necessary permits and licenses will be completed by client and/or DPT provider, unless specified for Eagle Synergistic. If necessary, traffic control will be organized with surrounding businesses and provided by DPT provider or client. Utility locates will be completed and verified by DPT provider and/or client prior to work beginning on site. DPT providers are able to push Eagle Synergistic’s HRSC probes to depth. Additional hours/charges may apply due to refusal or slower penetration rates. Eagle Synergistic will not be held responsible for any damage or liabilities caused by other subcontractors, including DPT providers. Eagle Synergistic will not be held responsible for normal impact to terrain, landscaping, etc., resulting from the track rig or the HRSC Command Center Units. Eagle Synergistic will take dissipation tests with client’s approval at recommended depths, when feasible, to calculate estimated K values. Individual sensors are not prorated. Running systems with or without the integrated HPT port, when applicable, does not affect pricing. Running systems with or without the EC, when applicable, does not affect pricing. Eagle Synergistic will provide ancillary items related to HRSC tools that the DPT operator will use during probe advancement and retrieval. DPT provider will follow state and site standards for drilling, coring, borehole abandonment, decontamination, and more. All applicable supplies and rentals will be handled by the DPT provider and/or the client. DPT Provider and clients will be responsible for all utility locates and any issues that arise from locates and utilities. Eagle Synergistic will direct DPT operator on the rate of push. Eagle Synergistic will decontaminate rods, if requested. Decontamination in between each boring will decrease production rates. If the lithological conditions encountered become potentially damaging to the probes and/or tool string, the HRSC operator will call refusal. Should the client insist that Eagle Synergistic continues the boring, the client will be held responsible for applicable tool damage or loss. If tooling is stuck or loss, retrieval of tools is a priority within the scope of the project. Due to the nature of this technology, and the process of hammering sensitive equipment into varying lithology, some downtime is expected. Downtime is accounted for within Eagle Synergistic’s HRSC day rate. If refusal is hit early due to lithology, Eagle Synergistic’s HRSC day rates still apply. • • • While Eagle Synergistic may make suggestions regarding confirmation sampling, the client will be solely responsible for • • • • • the collection, storage, and transportation of any samples. All costs associated with lab and sampling are the responsibility of the client. Eagle Synergistic holds the ability to charge a standby rate for delays to the project due to client, other parties, weather, or DPT provider. Elevation or GIS data will be provided via client for cross sections and 3D modeling service (if applicable). If requested, Eagle Synergistic has the ability to collect gps location and elevation data with the Emlid Reach RS+ or Trimble Geo7x. Additional time will be added to the scope for gps collection. Client is responsible for mapping of HRSC points; locations provided by Eagle Synergistic are field estimates, unless stated otherwise. Normal daily footage will be decreased with Low-Level MIP operations. Normal daily footage may be decreased with dissipation tests. • • • Multiple dissipation tests will reduce footage per day. • Eagle Synergistic field personnel are equipped to work in most weather conditions, to include rain and snow. If a project is delayed or called off by our client due to weather or issues outside of Eagle Synergistic’s control, a standby time fee may apply.

This interactive simulation can allow the client to simultaneously visualize the contamination plume(s), source(s), lithology intervals, high transmissivity zones, aquitards, topography, water tables, and migration pathways. Previously obtained groundwater and soil data can also be integrated into our models. Clients will receive a comprehensive 3D report which includes multiple views and descriptions of each 3D visualization. Eagle Synergistic will provide education on how to use the 3D viewer which allows the client to zoom, rotate, and change the isolevels, indicating different sensitivities of the contaminant plume and other properties. To assist the client in designing the remediation phase, Eagle Synergistic will also supply multiple videos and a condensed report specifically for remediation vendors to better understand the HRSC data.

The OIP system uses an UV or green light source to induce fluorescence of the polyaromatic hydrocarbons (PAHs) of the fuels, oils, and tars present in the soil. A down hole camera captures an image of the induced fluorescence. The captured image is then analyzed to determine the area of fluorescence. The NAPL hydrocarbon fuel, oil, or tar is measured as the percent area within the image that contains fluorescence. An OIHPT log includes (from left to right) an EC, fluorescence graph, along with actual fluorescence and visual images, HPT injection pressure (top axis) with HPT flow rate (bottom axis) and Estimated Hydraulic Conductivity (K) (top axis) with Absolute Piezometric Pressure (bottom axis) with a line showing where a dissipation test was taken (red triangle), and where DI Viewer calculated the groundwater depth based on the dissipation test (red circle). .

Tip resistance is a measurement of soil hardness, sleeve friction is an indication of the soil cohesive strength commonly seen with clays, and pore pressure is related to the pressure generated as the cone is advanced as well as an indication to the amount of clay in the formation. HPT-GWS — The HPT-GWS has the capabilities to obtain numerous discrete groundwater samples, while collecting EC and HPT pressure data for lithological and hydrogeological properties. DI water is used to purge the sampling line in between every sample which allows multiple samples to be taken every borehole. With a downhole transducer, we are able to detect zones of high yield. This is an excellent insitu profiling tool to target discrete groundwater samples on PFAS sites.
