POTENTIAL FOR USE OF EFFLUENT WASTEWATER TREATED BY SOIL AQUIFER TREATMENT IN BANNING, CALIFORNIA A Project Presented to the Faculty of California State University, San Bernardino In Partial Fulfillment of the Requirements for the Degree Master of Science in Earth and Environmental Sciences: Professional Sciences Masters by Arturo Castro Vela June 2015 POTENTIAL FOR USE OF EFFLUENT WASTEWATER TREATED BY SOIL AQUIFER TREATMENT IN BANNING, CALIFORNIA A Project Presented to the Faculty of California State University, San Bernardino by Arturo Castro Vela June 2015 Approved by: Dr. James A. Noblet, Committee Chair, Chemistry Dr. Brett Stanley, Committee Member Ann Marie Loconte, P.E., Committee Member © 2015 Arturo Castro Vela ABSTRACT With the ever increasing demand for potable water due to the continued increase in population coupled with the threat of California’s current drought, water will remain a limited resource that must be managed responsibly. In order to strategically plan and manage water use in the most beneficial manner, water providers must take into account all sources of water, including recycled water and their applications. Recycled water as a source for supplementing high quality potable water is a sustainable strategy that will prove to be an essential tactic in any water management plan. The purpose of this project is to emphasize the importance of supplementing potable water in the City of Banning by discussing the characteristics of California’s current water drought; evaluating the City of Banning’s available water supplies and current water demand; discussing the Soil Aquifer Treatment process; summarizing California’s regulations related to recycled water; and discussing the quality of recycled water available at NP-1, an unequipped City owned water well, by examining water quality testing on water samples taken from NP-1. Analysis of water available at NP-1 showed that with additional disinfection, the water pumped from NP-1 could meet the recycled water requirements in order to be used on a local golf course. The local golf course is currently being irrigated with potable water, which would be supplemented with the recycled water from NP-1. iii ACKNOWLEDGMENTS I wish to express my sincere gratitude to my committee members, Dr. James Noblet, Dr. Brett Stanley and Mrs. Ann Marie Loconte for being a part of this project and dedicating their time to its quality. I could not have completed this assignment without their knowledge. Additionally, I would like to thank my parents, Arturo M. Vela and Hilda C. Vela for their continued encouragement, support and guidance throughout my educational career. Without their work ethic that I attempted to emulate my accomplishments would have not been possible. I am deeply grateful for my beautiful, caring wife Amber Marie Vela for her love, patience, and motivation throughout this venture. Finally, I would like to say thank you to my baby boy Mateo Joren Joshua Vela who was born on March 9, 2015. He has renewed my dedication to self-improve all aspects of my life iv TABLE OF CONTENTS ABSTRACT .................................................................................................. iii ACKNOWLEDGMENTS ............................................................................... iv LIST OF TABLES ......................................................................................... vii CHAPTER ONE: INTRODUCTION .............................................................. 1 Summary and Purpose of the Project ................................................ 2 CHAPTER TWO: REVIEW OF LITERATURE 3 2014 California Drought ..................................................................... 3 City of Banning Water Supply and Demand ...................................... 8 Perennial Yield Estimates ....................................................... 9 Supply versus Demand ........................................................... 14 Well NP-1 .......................................................................................... 15 Soil Aquifer Treatment (SAT) ............................................................. 18 California Recycled Water Regulations ............................................. 20 Constituents of Concern ......................................................... 23 CHAPTER THREE: METHODOLOGY ......................................................... 25 CHAPTER FOUR: RESULTS ....................................................................... 28 CHAPTER FIVE: SUMMARY, CONCLUSIONS AND RECOMMENDATIONS 37 Summary ........................................................................................... 37 Conclusion ......................................................................................... 39 Tertiary Disinfected Recycled Water ....................................... 39 Disinfected Secondary – 2.2 Recycled Water ......................... 41 Disinfected Secondary – 23 Recycled Water .......................... 41 v Recommendations ............................................................................. 42 APPENDIX A: LETTER OF PERMISSION ................................................... 44 APPENDIX B: FIGURES .............................................................................. 46 APPENDIX C: TABLES ................................................................................ 52 APPENDIX D: ALLOWED RECYCLED WATER USES IN CALIFORNIA ......................................................................... 63 APPENDIX E: NP-1 WATER QUALITY ANALYSIS RESULTS .................... 66 REFERENCES ............................................................................................. 114 vi LIST OF TABLES Table 1.

Several identified factors contributing to the drought and the shortening of water supplies include statewide agricultural; urban and environmental demands at an all-time high; major reservoirs at half capacity and diminishing; a dwindling Sierra snowpack; and an increase in the use of water for fighting wildfires. Regional and local water suppliers are scrambling to conserve water and implement action plans for derailing the depletion of water supplies. This may be achieved by water resource managers who are tasked with analyzing their water portfolios to ensure that all available water supplies, such as recycled water, are used efficiently. Recycled water has, in some communities, not been widely accepted. Recycled water as a source of supplementing potable water can prove to be a sustainable water management strategy that can play an important role in building local self- reliance. The City of Banning currently treats approximately 2.1 million gallons a day of wastewater. The treated wastewater is then discharged into basins where it is percolated into the ground where it is treated further by a Soil Aquifer Treatment (SAT) process. It is believe that the final treated water can 1 be a potential source of recycled water for the City of Banning to be used for irrigation of golf courses, parks, school fields and other landscaped areas. Summary and Purpose of the Project The purpose of this project is to emphasize the importance of supplementing potable water with recycled water in the City of Banning by reviewing literature related to California’s current water drought; evaluating the City of Banning’s available water supplies and current water demand; discussing SAT; summarizing California’s regulations related to recycled
