A summary of the field activity and recommendations is contained within the following executive summary. Detailed supporting data and information are contained within the remaining sections of the report and appendices. 1.2 Findings h Drilling commenced on October 18, 2002 and was completed on November 3, 2002. • A nominal 12-inch borehole was drilled to a total depth of 1,132 feet below ground surface. • Based on geologic drill cuttings and geophysical logs, a decision was made to complete a - cased well to a total depth of 1,120 feet. • Alluvial material was encountered during the drilling from ground surface to a depth of 135 feet below ground surface. This material was made up of interbedded layers of sands, gravels, and clays. From 246 feet to total depth of 1,132 feet the geologic material encountered was interbedded layers of fractured and non-fractured Basalt. • Nominal six-inch diameter blank and perforated steel casing was installed into the borehole from ground surface to 1,120 feet Quad-row, 80-slot size casing was placed throughout the borehole starting at a depth of 160 to 380 feet, from 460 to 540 feet, from 700 to 880 feet, from 940 to 1,020 feet, and from 1,080 to 1,120 feet. The remaining sections of the well were completed with nominal six-inch diameter blank steel casing. • After the well was constructed, an air-lift and pump development program removed excess drilling fluid and formation fines from the annular space and borehole face. • Water quality samples were collected from the perforated sections of the well casing using a double swab air-lift device. A total of eleven water quality samples were collected and submitted for laboratory analysis. Results of the sample analysis indicated all samples exceeded drinking water standards for arsenic, iron, and manganese. • A 17-hour constant-discharge test was conducted on the test well with the discharge rate held constant at 250 gallons pet' minute (gpm). A specific capacity of 2.0 gpm/ftdd. was calculated from the drawdown data. An average transmissivity value of 3,081gal/day/ft. was calculated from the drawdown and recovery data. 1 • A greater thickness of basalt was encountered at this location than what was expected. -.- Based on local geology found at the school site borehole, proximity to the Prosser Heights production well, and the geophysical survey conducted by Cooksely Geophysical, a geologic strata composed of alluvial material (ground surface to 200 feet), s underlined by basalt (Lousetown Formation - 200 to 600 feet), and finally by alluvial material (Truckee Formation - 600 to 1,000 feet) was expected. What was encountered was alluvial material from ground surface to 134 feet followed by basalt from 134 feet to total depth of 1,132 feet. The Truckee Formation was never encountered. 1.3 Recommendations The following are the proposed recommendations based on data analysis of the information collected during the dolling, testing, and water quality analysis of the Alder Drive exploration test well. • Because of the poor water quality which was encountered in the test well from ground .. surface to a depth of 1,132 feet completing a production well to this depth is not recommended. • Utilize the Alder Drive well as a monitoring well to measure water levels on a quarterly basis. • Drill an exploration well approximately 500 feet due west of the school site test borehole. Given the favorable results encountered at the school site test borehole and the proximity to the Prosser Heights production well, it is anticipated that a production well at this location may yield upwards to 1,000 -pm. 2.0 INTRODUCTION This report presents the results of a ground water exploration drilling program conducted at the Alder Drive exploration test well site in Truckee, California. The location of the test well is shown on Figure 1. Truckee Donner Public Utility District contracted with AquA Hydrogeologic Consulting, Reno, Nevada to provide on-site supervision for the drilling, construction, development, and testing of the Alder Drive exploration test well. This report summarizes all field activity and includes pumping test analysis, water quality analysis, and recommendations. 3 3.0 GEOLOGIC AND HYDROGEOLOGIC SETTING 3.1 Geologic Settinf4 The geologic setting found within the area of Alder Drive exploration test well is one of alluvial material comprised mostly of interbedded layers of sand, clay, and gravel of varying sizes and thicknesses from ground surface to an approximate depth of 135 feet. Below this depth to total depth drilled of 1,132 feet, basalt was encountered. In some cases where the basalt was fractured, the fractures were clean, while in other areas, the fractures contained clay. The basalt material was identified as the Lousetown Formation which contains olivine basalts, sediments, and cinders. All three of these materials were encountered during the drilling of the Alder Drive borehole. The Lousetown basalt is comprised of massive flows with vesicular zones. The flows are massive with vesicular zones at the top and bottom. In between the top and bottom zones, volcanic cinders and some sediment were encountered. The sediment material found within the Lousetown Formation are usually poorly to moderately sorted angular to silty sands. Underneath the Lousetown Formation is the Truckee Formation which is composed of lake and stream sediments. Within the Truckee Formation two predominant rock types are identified, one is fine-grained lake sediments containing siltstone and the second is fine to coarse-grained ,. sandstone and gravel of su-cam origin. Due to the faulting activity which resulted in the Truckee Formation being down thrusted in the vicinity of the Alder Drive Test Well, the Truckee Formation was not encountered during the borehole drilling. '#3 A geologic map of the area surrounding the Alder Drive exploration test well is shown on Figure 2. The seismic geophysical survey conducted by Cooksley Geophysical fire., Redding, i California that was completed through this area in May-June, 2002 provided both geologic and E `s =j structural information regarding the area geology.

Appendix A contains a full description of the material encountered in the Alder Drive borehole. 3_2 Hydrogeologic Setting The hydrogeologic setting for this area is one of a 100 to 200 foot thick sequence of alluvial material made up of sands, some gravel, and clays. This alluvial material at depth is under laid s by basalt, which is typically identified as the Lousetown Formation. Underneath the Lousetown Formation is the Truckee Formation which is composed of lake and stream sediments. The basalt which contained interbedded layers of sediments usually comprised of cinders with some 1 clay. A significant amount of fractures were recorded by drill rig response and by the downhole geophysical survey. These fractures where they are clean and not containing clay conveyed the ground water. Just west of the borehole and possibility encountered at depth in the borehole was sj a fault. The fault trend is north, northwest by south, southeast. t Throughout the Martis Valley groundwater basin, the ground water is derived both from the Lousetown basalt and the underlying sediments of the Truckee Formation. At the Alder Drive $ exploration test well location the ground water aquifer is contained within the basalt and associated fractures (Lousetown Formation), while the Truckee Formation was not encountered. The water level at the test well was measured at 165 feet below ground surface.

A cement seal was then placed from 50 feet to ground surface. t 4.4 Air-Lift Well Development Chemical well development was initiated by adding calcium hypochlorite to the borehole fluid during the installation of the filter pack. Upon completion of the filter pack installation and setting of the cement seal, the well bore and filter pack were cleared of drilling fluid by stage air- lifting starting at the well bottom. After the well was air-lifted from the bottom of the well-bore additional air-lift development was conducted as the drill steel was being removed from the well- bore. After this was completed, a second mud dispersant (Aqua Clear) was placed into the well bore. This chemical was swabbed into place opposite each of the 20-foot perforated sections. After allowing the chemical to remain in the well-bore for approximately two hours air-lift development using a double swab commenced. A total of 24 hours and 36 minutes was spent developing the well using the air-lift double swab. s, Because of a time constraint imposed by the Lahontan waiver permit requirement for completion is of the project, some of the perforated zones were not completely sand and silt free when the #;= decision was made to move to a new section and continue the development process. This did not affect the well's yield potential. However if this were a production well additional time would have been spent on each section it make it sand and silt free before moving onto a new screen/perforated section. 4.5 Water Quality Sampling and Analysis Upon completion of the air-lift development program water quality samples were collected at specified intervals. A total of 11 samples were collected, Figure 4 shows the results in graphical form, while Table 1, contains the laboratory results of each sample collected. All I of the samples collected and analyzed exceed the drinking water standards for arsenic (proposed), iron, and manganese. 10 A complete record of the water quality sampling analysis is included in Appendix B.

This pump was capable of producing approximately 250 gPm with a pumping water level of approximately 300 feet. The production of the pump was less than what the contract called for, but due to the Lahontan waiver permit deadline, it was necessary to use this pump instead of requiring the contractor to replace it with what was specified in the signed a.- contract. Development commenced on November 12, 2002 at 3:03 p.m. The well was surged at progressively higher pumping rates for 5 hours and 30 minutes. At the end of pump development, discharge from the well contained some sand and silt, but because of the permit X'. deadline the decision was made to allow the water level to recover for approximately 10 hours and then proceed with the scheduled constant-discharge test. 12 5.0 PUMPING TEST AND ANALYSIS The pumping test program on the Alder Drive exploration test well was conducted November 13-14, 2002. The pumping rate was held constant at 250 gpm. The main purpose of the pumping test was to provide aquifer parameters and to collect a water quality sample at the end of the testing period. Both of these tasks were accomplished. A complete set of drawdown and recovery data are included in Appendix B. _ 5.1 Constant-Discharge Test A constant-discharge pumping test commenced on November 13, 2002 at 8:00 a.m. and ended on November 14, 2002 at 1:30 a.m. A minimum 24-hour pumping test was originally scheduled; however after 17 hours and 30 minutes at a pumping rate of 250 gpm, the pump could no longer 0 produce the 250 gpm flow-rate as the water level continued to drop. At this time the decision 1V was made to terminate the test. Water levels were measured throughout the testing period by using a pressure transducer. The discharge was held constant at 250 gpm. A pre-constant water level was measured at 179.414 feet below top of casing. At the end of the pumping period, the water level was measured at 288.44 feet below top of casing. This resulted in a calculated drawdown of 119.74 feet. A specific capacity of 2.08 gpm/ftdd. was then calculated. 5_2 Pumping Test Analysis Analysis of the pumping test drawdown and recovery data involved using analytical software which incorporates type curves of the Theis (confined analysis) and the Cooper-Jacob (straight- line approximation) analytical methods. These methods produced similar results analysis using the Cooper-Jacob method produced a transmissivity value of 2,265 gpolft. (figure 5). The Theis s analytical method for confined aquifers produced a transmissivity value of 4,122 gpolft (figure 's 6). Recovery data utilizing the Theis Recovery method produced a transmissivity value of' 2,857.03 gpd/ft. (figure 7). f? Because an observation well was not available for monitoring water levels during the pumping and recovery periods, calculation of an aquifer storage coefficient value was not possible. However, given the fractured aquifer system that was encountered during the drilling of the borehole, a semi-confined to confined aquifer could be assumed. Normal storage coefficient values for these aquifer conditions would be in the range of 0.001 to 0.00001. A specific capacity value of approximately 2 gpm/ft.dd, was calculated from the pumping rate verses the drawdown data. This value means a limited ground water resource for this area. Depending on well design, construction, and total depth drilled, this ground water resource may ' have the potential of yielding approximately 400 to 500 gpm at the present location. � 13 Figure 5 Cooper-Jacob Straight Line Analysis [ 120.0 oO 96.0 .._ . :�r'i ... _... .
