Skaggs, P.E. Dee Jaspar and Associates, Inc. 2730 Unicorn Road, Bldg A Bakersfield, CA 93308 DATE: February 6, 2018 SUBJECT: Allensworth Community Services District Drilling of a Casing Hammer Test Well INTRODUCTION The Allensworth Community Services District (ACSD) contracted with Cascade Drilling, LP (Cascade) to construct a casing hammer test well. This letter summarizes the test well construction, water quality, and recommendations. The test well is located on APN 333-252-020 approximately 2.5 miles east of Hwy 43 in Section 13, T.24S., R.24E., M.D.B.&M. in the City of Allensworth and is approximately 575-ft east of the existing ACSD Well No. 1. The test well was drilled and constructed between January 8, 2018 and January 31, 2018. DRILLING Cascade began by hand augering a 16-inch diameter well hole to approximately 8-inches below ground surface using small shovels and hand trowels under the supervision of the project biologist as outlined in the Mitigated Negative Declaration. The project biologist was on-site full-time from mobilization, test well drilling, and demobilization to ensure compliance with the Mitigated Negative Declaration. An 8-inch diameter casing hammer test well was drilled to a depth of approximately 439feet below ground surface for purposes of finding water producing formations and testing water quality. Composite soil samples were collected across 10-ft intervals during the test well drilling 1 Page for visual description of the formation in the field. All samples were logged visually in the field under the direction of a California Professional Geologist in accordance with the Unified Soil Classification System. A detailed lithologic log is provided in Appendix A. The Corcoran Clay was encountered at an approximate depth of 377-ft to 437-ft. As the test well was drilled Cascade Drilling pushed an 8-inch steel casing pipe behind the drill bit. The casing pipe was landed in a clay formation when encountered and the hole drilled below the casing pipe into water producing formations. Cascade then airlifted the water for approximately 15 minutes and then installed a submersible pump. Cascade pumped each water sample for approximately 2 hours and then collected water quality samples. Water producing formations were identified at the following depths and selected for water quality zone testing: Zone 1: 97’ to 135’ Zone 2: 196’ to 228’ Zone 3: 237’ to 248’ Zone 4: 296’ to 307’ Zone 5: 337’ to 350’ Zone 6: 437’ to 439’ ZONE TESTING A total of six zone tests were constructed at the depths noted above and water quality data obtained for each zone. A water quality summary is provided below in Table 1. Zone 1 2 3 4 5 6 Flow 25 gpm 41 gpm 40 gpm 16 gpm 8 gpm 35 gpm TDS 460 220 150 150 160 230 Table 1 Zone Testing – Water Quality Summary EC pH GA As 681 7.8 11.1 3.0 275 8.1 4.6 8.0 230 8.2 2.8 18.0 216 6.2 1.3 32.0 234 7.0 5.9 160.0 229 8.8 4.7 91.0 NO3 22.4 6.0 7.0 <0.4 <0.4 0.6 Fe <30.0 <30.0 <30.0 <30.0 <30.0 40.0 Mn 3.1 6.0 6.2 20.5 14.5 11.3 Flow = Pumping Rate for that particular zone. TDS = Total Dissolved Solids EC = Electrical Conductivity in umhos/cm GA = Gross Alpha in pCi/L As = Arsenic in ppb NO3 = Nitrate in ppm as Nitrate Fe = Iron in ppb Mn = Manganese in ppb DBCP, EDB, and 1,2,3-TCP were below the detectable limits in all zones. Hexavalent Chromium ranged from about 3 ppb to 5 ppb which is below the proposed MCL of 10 ppb. Please refer to Appendix B for details on water quality data. 2 Page The gross alpha ranged from 3 to 11 picocuries per liter which is below the MCL of 15 picocuries per liter. The Nitrate concentration ranged from 0.6 ppm to 22.4 ppm which is below the MCL of 45 ppm as Nitrate. Iron and Manganese concentrations in all samples were less than the respective MCL’s of 300 ppb and 50 ppb. Arsenic was the primary constituent of concern and was present in all samples. The Arsenic was above the MCL of 10 ppb in all samples below a depth of 237-ft. The Arsenic ranged from 3 ppb to 8 ppb in samples above 228-ft. WELL RECOMMENDATION The proposed production well design is based on the water quality zone testing and the lithologic log in an effort to maximize yield and produce the best blended discharge water quality possible. Sieve analyses by Roscoe Moss for two fine sand samples recommend a slot size of 0.06 inch for the perforated interval and an 8x16 gravel gradation. It is recommended to construct a well at the site that is perforated from 110-ft to 215-ft. Blank casing would be installed from ground surface to 110-ft and from 215-ft to 225-ft below ground surface. The gravel feed tube would be installed from ground surface to 90-ft and the sounding tube from ground surface to 105-ft below ground surface. The gravel pack would be installed from 225-ft up to 85-ft below ground surface and then a cement annular seal from that depth up to ground surface. See the attached well casing diagram in Appendix C. It is estimated that a properly constructed well as described above would produce approximately 500 gpm. CONCLUSION A hydrogeologic summary from Ken Schmidt & Associates, Inc. is attached in Appendix D. Cascade destroyed the test well by filling with cement slurry from the bottom of the well up to 6-ft below ground surface in accordance with the County of Tulare standards. The area was then backfilled and compacted to natural grade and the project area cleaned up and restored to its original conditions. All site work, soils disposal, and water disposal was performed in accordance with the Contract Documents and under the oversight of the project biologist. A Well Completion Report for the Test Well and a Well Completion Report for the Test Well Destruction are attached in Appendix E. The environmental aspect of drilling a municipal well in this location is going to be a major obstacle and will need to be prepared for. It is recommended that BNLL surveys be performed at the appropriate times and efforts made to isolate areas that are clear from the migration of habitat into those areas. In addition meetings with CDFW and the project biologist are recommended to develop guidelines for drilling and construction that will be acceptable to CDFW. 3 Page APPENDIX A TEST WELL LITHOLOGIC LOG 4 GEOLOGIC LOG FOR ALLENSWORTH CSD TEST WELL NO. 1 Depth (feet) Description 0-60 Brown silty and clay 60?70 Brown medium sand with gravel 70?80 Brown clay and gravel with coarse sand 80-135 Brown gravel with coarse sand 135-136 Brown clay 136-150 Brown gravel with coarse sand 150-160 Brown clay 160?205 Brown clay with some coarse sand and gravel 205?210 Brown fine sand 210~220 Brown coarse sand and gravel 220-228 Brown coarse sand 228-230 Brown clay 230-248 Brown fine sand 248?257 Brown clay 257?263 Gray-brown coarse sand and gravel 263?265 Gray-brown clay 265-276 Gray-brown clayey fine to coarse sand with gravel 276?280 Gray-brown clay with some coarse sand and gravel 280m302 Gray?brown clay 302~310 Gray clay 310-320 Gray fine to coarse sand with gravel 320?325 Gray medium to coarse sand with gravel 325-327 Gray clay 327?340 Dark gray fine to medium sand with clay 340?352 Dark purple-gray clay with fine to medium sand 352-360 Purple-gray clay 360-376 Brown?gray clay 376?377 Brown?gray clay with coarse sand 377?400 Gray clay (Corcoran Clay) 400?437 Black clay (Corcoran Clay) 437-439 Sand APPENDIX TEST WELL WATER QUALITY DATA 5 DEE JASPAR ASSOCIATES, INC.

Water Amendments Application Notes: The Amendments recommended on the previous pages include: Gypsum: This should be applied at least once a year to the irrigated soil surface area. Gypsum can also be applied in smaller quantities in the irrigation water. Apply the smaller (bracketed) amount of gypsum when also applying the recommended amount of Sulfuric Acid and the larger amount when applying only Gypsum. Sulfuric Acid: These products should be applied as needed to prevent emitter plugging in micro irrigation systems and/or as a soil amendment to adjust soil pH to improve nutrient availability and to facilitate leaching of salts. Please exercise caution when using this material as excesses may be harmful to the system and/or the plants being irrigated. The reported Acid requirement is intended to remove approximately 80 of the alkalinity. The ?nal pH should range from 5.4 to 6.7. We recommend a ?eld pH determination to con?rm that the pH you designate is being achieved. This application is based upon the use of a 98% Sulfuric Acid product. The application of Urea Sulfuric Acid is based upon the use of a product that contains 15 Urea (1.89 Nitrogen), 49% Sulfuric Acid and has a speci?c gravity of 1.52 at 68 Guidelines for the above interpretations are sourced from USDA U.C.

Water Amendments Application Notes: The Amendments recommended on the previous pages include: Note: Cloor coded bar zg?rhaphs?hwave bee" Gypsum: This should be applied at least once a year to the irrigated soil surface area. Gypsum can also be applied in smaller quantities in the irrigation water. Apply the smaller (bracketed) amount of gypsum when also applying the recommended amount of Sulfuric Acid and the larger amount when applying only Gypsum. Sulfuric Acid: These products should be applied as needed to prevent emitter plugging in micro irrigation systems and/ or as a soil amendment to adjust soil pH to improve nutrient availability and to facilitate leaching of salts. Please exercise caution when using this material as excesses may be harmful to the system and/or the plants being irrigated. The reported Acid requirement is intended to remove approximately 80 of the alkalinity. The ?nal pH should range from 5.4 to 6.7. We recommend a ?eld pH determination to con?rm that the pH you designate is being achieved. This application is based upon the use of a 98 Sulfuric Acid product. The application of Urea Sulfuric Acid is based upon the use of a product that contains 15% Urea (1.89 Nitrogen), 49% Sulfuric Acid and has a speci?c gravity of 1.52 at 68 Guidelines for the above interpretations are sourced from USDA U.C.

Water Amendments Application Notes: The Amendments recommended on the previous pages include: Gypsum: This should be applied at least once a year to the irrigated soil surface area. Gypsum can also be applied in smaller quantities in the irrigation water. Apply the smaller (bracketed) amount of gypsum when also applying the amount of Sulfuric Acid and the larger amount when applying only Gypsum. Sulfuric Acid: These products should be applied as needed to prevent emitter plugging in micro irrigation systems and/or as a soil amendment to adjust soil pH to improve nutrient availability and to facilitate leaching of salts. Please exercise caution when using this material as excesses may be harmful to the system and/or the plants being irrigated. The reported Acid requirement is intended to remove approximately 80 of the alkalinity. The ?nal pH should range from 5.4 to 6.7. We recommend a ?eld pH determination to con?rm that the pH you designate is being achieved. This application is based upon the use of a 98 Sulfuric Acid product. The application of Urea Sulfuric Acid is based upon the use of a product that contains 15% Urea (1.89 Nitrogen), 49% Sulfuric Acid and has a speci?c gravity of 1.52 at 68 Guidelines for the above interpretations are sourced from USDA U.C.
