As previously reported, flowing springs were observed in the bottom of the pool and the holding tank. Although the depth of the warm water well was reported 1 to be up to 700 feet below ground surface (bgs), the total depth that was monitored in this assessment was only 21.1 feet bgs, which would be more typical of an older well that was likely hand-dug. The temperature of the well water was almost constant, ranging from 80.4 degrees Fahrenheit (OP) at the surface of the water table to 81.43 OP at the bottom ofthe well. Water quality from the warm water well was compared to water quality from two other springs, one seep, and groundwater encountered in two test pits. With the exception of one test pit (TP-4) (Figure 2) located in the southeast comer of the Site near Otis Street, the water-quality signatures of the all samples are very similar to the warm water well, and indicative of geothermal origin. Due to the shallow depth, low temperature, and relatively poor water quality, the warm water well is not a viable geothermal resource, or a good water source for irrigation needs. The sample from test pit TP-4 is markedly different from all other samples, and appears to be influenced by nearby surface water infiltration from a nearby source in the southeast (upgradient) comer of the Site. Spring-l and Seep-3 (Figure 2) are emanating from man-made structures. Groundwater was encountered at 7 feet bgs to the south of these features, and was not encountered in test pits advanced to a depth over 10 feet bgs north of the structures. This implies that shallow groundwater daylighting at the ground surface is not the source of the springs in the wetland areas. Therefore, the source of the wetland water may be eliminated if the man-made structures are removed. Details supporting the conclusions summarized above are presented for each task below. 1 Verbal introductory discussions with Sage Cascade Earth Sciences -Medford, OR PN: 2624019/ Doc: 2624019 GeoThermal Assessment Geothermal Assessment October 24, 2006/Page v I" I I I I I I I I I I I I I I I I I I I I 1.0 Task 1. Investigation of Pool and Holding Tank During Maintenance Draining On Tuesday, August 1,2006, a CES Staff Engineer visited the Site while the pool and holding tank were being drained for maintenance. The purpose of the visit was to investigate the springs that reportedly existed within the pool bottom. Two spring vents, both approximately 16 inches in diameter, were observed in the bottom of the pool (Photograph 1, Appendix A). One opening is bordered by a wooden frame and the other is an opening in the concrete. The two openings are spaced approximately two feet apart (Photograph 2). The close proximity of the openings may suggest a single spring. In order to determine whether the two vents are from one or two springs, a geotechnical assessment of the subsurface, including water chemistry, would be necessary. A geotechical assessment of the subsurface was beyond the scope of work for this project. However based on the observations discussed below, for all intent and purposes, it is reasonable to assume that the two vents represent one spring. The water from the pool empties into a drain located near the two spring vents. The pool was empty at the time of inspection. The water from the spring vents in the bottom of the pool was flowing to the drain (Photograph 3). A small bucket with I-quart gradation marks and a wrist watch were used to measure the flow rate from the spring vents. At the time of inspection, the flow rate was estimated to be 2.25 gallons per minute (gpm). The temperature of the water was measured at the vents using a digital thermometer, and was 78 degrees Fahrenheit (0 F) for both spring openings. In addition to the two observed spring vents, water was observed to be flowing through the walls on the south and east sides of the pool (Photograph 4). The concrete surfaces of the pool are weathered, showing signs of abrasion and cracking. The cracks and surfaces have been maintained with a patchwork of epoxies and sealants. The deepest part of the pool is approximately eight feet. The water flowing through the pool walls suggests a shallow water table and high pore pressures along the southern margin of the pool (Photograph 5). The presence and build-up of water in the soil applies increased stress against the walls of the pool and forces water to flow through them. The pool is also filled from an artesian warm water well located approximately 500 feet southeast of the pool-house. The temperature of the water of the artesian well was measured using a digital thermometer. The temperature of the water was 820 F at the time of inspection. The flow rate of the artesian well was not measured. Water from the artesian well is conveyed to the pool holding tank (Figure 2) via a subsurface pipe. The holding tank is constructed of stone and is approximately 10 feet long, 10 feet wide and 10 feet deep and can hold approximately 7,480 gallons of water. The holding tank was empty at the time of inspection. In addition to the water flowing into the holding tank from the artesian well, water was observed to be emanating from a spring in the bottom of the holding tank (Photographs 6 & 7). Therefore the holding tank also serves as a spring box.

Down Hole Logging of the Warm Water Well The purpose of the temperature profile was to measure the depth of the well and to characterize the water temperature variation by depth. It was suggested by persons familiar with the artesian warm water well that the depth of the well approached 700 feet below ground surface (bgs). Prior to measuring the temperature profile, CES researched the well log database of the Oregon Department of Water Resources. CES was unable to locate any documentation for the artesian warm water well located on the Helman Springs Subdivision. Therefore, CES prepared to measure the water temperature at one foot intervals up to a depth of 700 feet bgs. 2.1 Methods CES performed the down-hole field work on August 16, 2006. The temperature and depth data were measured with an In-Situ Inc., Leve1lROLL 700 sensor (herein referred to as the sensor). The sensor contains a pressure transducer (water level sensor), a thermistor (temperature sensor), a data logger and an internal power source. The sensor was connected to 700 feet of RS-232 cable and integrated with a laptop computer. The top of the well housing is comprised of a 6' wide x 6' wide x 3' tall concrete tank, similar to a Jacuzzi pool. The actual top of the steel well casing is located at the bottom of the well housing pool at ground level. A wooden plank was placed over the well housing pool. The spool of RS-232 cable, along with the sensor, was mounted to the plank and suspended over the opening of the well casing (Photograph 8). The sensor was calibrated for both depth and temperature parameters in the field prior to collecting data measurements. Once the sensor was calibrated and the results verified, the sensor was lowered into the well at one foot increments. Water level and temperature data was measured for 50 seconds at each one foot interval. The data was logged at a frequency of one measurement every 250 milliseconds, resulting in a total of 250 measurements for each one foot interval. A final set of measurements were collected at the bottom of the well. The sensor was placed at the bottom of the well and allowed to collect measurements for thirty minutes to verify that the system was in equilibrium. 2.2 Results Verification of the sensor was confirmed by comparing depth and temperature measurements from several instruments. The results of these measurements are presented in Table 1.

The results of the temperature profile for the well are presented in Figure 3. The minimum temperature of the well water is 80.4 OP at the surface of the well housing pool, rising slightly, to a maximum temperature of 81.45 OP at the bottom of the well. The temperature at the opening of the well casing, starts at 80.4 OP and increases over the measurement interval to 80.8 OP. The next measurement interval, collected at a depth of 3.25 feet, is located 1.14 feet bgs. The temperature at this depth, starts at 80.8 OP and gradually increases over the measurement interval to 81.2 <>Po Review of Figure 3 shows that the water temperature remains relatively constant from about 4 feet bgs to the bottom of the well. 2.3 Discussion The precision of the sensor was more than satisfactory for this assessment. Therefore, the results of this study are presented with enough detail to provide specific conclusions. The depth of the well is 21.1 feet bgs- significantly less than the anticipated 700 feet bgs. The temperature of the water increases by approximately one degree from 80.4 OP at the top of the water column to 81.45 OP at the bottom. Due to the relatively low water temperature in a short water column, the well is not a viable resource for geothermal potential. The increase in temperature with depth suggests a hotter water resource at a greater depth, but the exiting well would have to be deepened or another new well would have to be installed. 3.0 Task 3. Water Quality Comparison of Warm Water Well to Other Waters The objective of this task was to compare the water-quality signature of the warm water well to other water sources at the Site in order to assess differences and/or similarities. 3.1 Methods Three springs in wetland areas were identified for sampling (Figure 2). In addition, Sage retained a geotechnical engineer to install test holes using a backhoe at the Site on August 16, 2006 (Photograph 9). Groundwater was encountered in two of the seven test pits, and CBS collected water samples from both test pits. CBS collected six water samples from the areas identified below and shown on Figure 2. · warm water well (W -1) . spring in the open space on lot 19 (Spring-I) . spring near the west wall of the pool house on proposed lot 18 (Spring-2) . seep2 on proposed lot 10 (Seep-3) . groundwater encountered in test pit near the southwest comer of the Site (TP-2) . groundwater encountered in the test pit in the southeast comer of the Site (TP-4) 2 For purposes of this report, a seep is a spring with no discernable flow. Cascade Earth Sciences -Medford, OR PN: 2624019/ Doc: 2624019 GeoThermal Assessment Geothermal Assessment October 24, 2006/Page 3 I I I I I I I I I I I I I I I I I I I The analyte suite consisted of: · major ions (calcium, magnesium, sodium, potassium, lithium, carbonates, sulfate, chloride, fluoride), . nutrients (nitrate, nitrite), · trace metals (aluminum, antimony, arsenic, barium, beryllium, boron, cadmium, chromium, copper, iron, lead, manganese, nickel, selenium, silver, thallium, and zinc), · oxidation/reduction potential (redox) and . field parameters (temperature, conductivity, and pH). Field work was performed on August 16 and 22, 2006. Spring-l appears to be developed. Though the edges are covered with thick vegetation, there is an open water area approximately 4.6 feet deep and 6 feet wide. Exploration of the bottom revealed a hard, flat layer. The hard material was not identified. Water was sampled from the spring's open area. Flow was measured from a temporary weir several feet downstream from the spring using a bucket and stopwatch (Photographs 10 and 11). Small clearing basins were hand dug at Spring-2 and Seep-3 in order to collect water samples. The basins were left several hours to allow the spring flow to come back into equilibrium prior to collecting water samples (Photographs 12 and 13). During the placement of the clearing basins field staff encountered a man made structure at Seep-3 (Photograph 14). Further exploration following sampling revealed the intact edge of a buried wooden-stave barrel with open water under the mass of overgrown roots on the inside edge of the staves, and soil on the outside edge. The seep is emanating from a wooden barrel of some kind. No discernable flow was observed at Seep- 3. Flow from Spring-2 was measured several feet downstream of the clearing basin by creating a temporary weir, and using a bucket and stopwatch. 3.2 Results Water quality results are shown in Table 2. Parameters that were not significant in comparing water quality signatures are not shown in Table 2. For example, silver, beryllium, and cadmium were not detected in any of the water samples, and are therefore not shown. Copies of all laboratory results are included as Appendix B. Nitrate was not detected in any sample, with the exception of TP-4 where it was measured at 3.94 milligrams per liter (mgIL). The presence of nitrate in groundwater is very often associated with human activities at the land surface from fertilizers, livestock, septic systems, etc. With the exception of TP-4, the pH measurements in all samples were relatively high (or basic), ranging from 8.75 standard units (Seep-3) to 9.64 (Well-I). As a comparison, the Oregon Department of Environmental Quality secondary standard for pH is between 6.5 and 8.5. The pH at TP-4 was 6.48, similar to precipitation and surface water. With the exception of TP-4, the conductivity in all samples was similar, ranging from 603 micro Siemens (uS) (Spring-2) to 754 uS (TP-2). Conductivity at TP-4 was lower at 431 uS. Cascade Earth Sciences -Medford, OR PN: 2624019/ Doc: 2624019 GeoThermal Assessment Geothermal Assessment October 24, 2006/Page 4 I I I I I I I I I I I I I I I I I I I With the exception of TP-4, the oxidation/reduction potential (redox) for all samples was negative, ranging from -138 (Spring-2) to -215 (Spring-I). The redox ofTP-4 was positive 64.6, indication a more oxidized environment. A trilinear diagram is a useful way to look at similarities and differences in the basic chemical makeup of water from different sources. The major positively charged ions (cations), and negatively charged ions (anions) that are found in virtually all natural water sources are plotted on the diagram. Where they plot on the diagram is a result of the relative concentration of one ion in the sample to other ions in the sample. The size of the point that is plotted is relative to the total dissolved solids in the sample. Trilinear analysis of all water samples is shown in Figure 4. With the exception of TP-4, all samples are clumped together in the anion triangle due to the relatively high chloride concentrations. In comparison, TP-4 is relatively high in carbonates, with almost no chloride. The well, springs and seep all plot together in the cation triangle as well, comprised almost entirely by sodium. TP-2 has the highest total dissolved solids (IDS) of all samples. The higher IDS and the location of TP-2 relative to the clumped points and TP-4 may indicate mixing of the groundwater at TP-4 and the geothermal waters in the well and springs. Concentrations of several metals, including aluminum, iron, and manganese were higher in the test pit samples. This is not surprising since the samples in the test pits were collected immediately after excavation, and the water was turbid with suspended sediments. However, with the exception ofTP-4, boron concentrations for all samples were similar, ranging from 3.73 mgIL (W-I) to 4.73 mgIL (TP-2). Boron was markedly lower in TP-4 at 0.70 mgIL. Flow measured at the two springs was 0.42 gallons per minute at Spring-I, and 0.33 gallons per minute at Spring-2. Discemable flow was not observed at Seep-3. These flows are relatively low in comparison to the artesian flow of the warm water well. 3.3 Discussion With the exception of the groundwater encountered in the test pit in the southeast comer of the Site near Otis Street (TP-4), there is a marked similarity in water quality from the different sources. The water quality is indicative of geothermal origin, as evidenced by high pH, reduced conditions, high sodium and chloride concentrations. Groundwater at TP-4 is different from all other samples, and shows contribution of surface water as evidenced by the presence of nitrate, and neutral pH. The source of groundwater at TP-4 is likely the inftltration of nearby surface water south of Otis Street. Groundwater at TP-2 is likely a combination of mixing between the surface-water derived groundwater in TP-4 and the geothermal-derived water in the other locations. Spring-l and Seep-3 are emanating from man-made structures. Groundwater was encountered at 7.3 feet bgs to the south of these features, and was not encountered in test pits advanced to a depth of over 10 feet bgs north of the structures. This implies that shallow groundwater daylighting at the ground surface is not the source of the springs in the wetland areas. Therefore, the source of the wetland water may be removed if the man-made structures are removed.

For example, though boron is an essential plant nutrient at low concentrations, it can be toxic to many plant species, especially trees, when concentrations in water exceed approximately 0.5 to 0.75 mgIL. The boron concentration in the warm water well is over five times greater than these values. Prepared by: CASCADE EART Robert A.

J Analyte detected below the Minimum Reporting Limit (MRL) and above the Method Detection Limit (MOL). MI Surrogate or Matrix Spike recovery is out of control limits due to matrix interference. N See Case Narrative. NI Some QA criteria may be outside control limits. Insufficient sample remains for reanalysis. R RPD outside accepted recovery limits. R1 Analyses are not controlled on RPD values from sample concentration less than 10 times the reporting limit. . R2 Analyses are not controlled on RPD values from samples concentrations less than 5 times the reporting limit. R3 The RPD and/or % recovery for the OUP or QC spike sample cannot be accurately calculated due to the high concentration of analyte already present In the sample. R4 Duplicate analysis failed due to result being at or near method reporting limit. RPD Relative percent difference. Reporting Limits: Report limits (MDLs & MRLs) are adjusted based on variatiqns in sample preparation amounts, analytical dilutions, and percent solids, where applicable. S 81 Spike recovery outside accepted recovery limits. Surrogate or Matrix Spike recovery is outside of control limits due to dilution necessary for analysis. Sub-contracted to another laboratory for analysis. Toxicity Characteristic Leaching Procedure - Sample submitted contained < 0.5% solids. The motor oil elution pattern for the sample is not typical. The sample'appears to be a heavier hydrocarbon range than motor oil. The sample appears to be a lighter hydrocarbon range than motor oil.
