The chemical properties of organics of health concern – hydrophobic and not water soluble - results in a low bioavailability to plants. Plant growth is dependent on the water solubility of nutrients and minerals and water is the transporting vector. Organics with a low water solubility will therefore not be taken up by plants. The presence of organic environmental pollutants, like dioxins and PCBs in agricultural crops is more the result of atmospheric deposition than direct absorption from contaminated soil. The analytical procedures for many organics are complicated and expensive – dioxins are a good example – which is an. | NJ@AT Corporation for Advancer Advanced Technology and ivision of xiente New Jersey Department of Environmental Protection Division of Science Research Technology ethnology Evaluation and Assessment OF Organic Chemical Removal technologies for New jersey drinking Water Ground Water Report January 2007 BLACK VEATCH building a uv rid I i Here nee ENERGT WATER - INFORMATION GOVERNMENT TABLE OF CONTENTS CHAPTER 1 - INTRODUCTION. 1 BACKGROUND. 1 PURPOSE AND SCOPE. 2 LITERATURE REVIEW. 2 CHAPTER 2 - OCCURRENCE OF UOCs IN NJ GROUND WATERS. 4 NJDEP STUDIES. . . 4 ORGANIC CHEMICALS DETECTED IN NJ GROUND WATERS. 5 CATEGORIZATION OF DETECTED UOCs. 7 CHAPTER 3 - AVAILABLE TREATMENT TECHNIQUES. 10 INTRODUCTION. 10 ADSORPTION PROCESSES. 11 General Process Description. 11 Factors Affecting Process Efficiency. 12 Applicability to UOC oxidatiOn General Process Description. 14 Factors Affecting Process Efficiency. 16 Applicability to UOC AIR STRIPPING processes. 19 General Process Description. 19 Factors Affecting Process Efficiency. 19 Applicability to UOC membrAne General Process Description. 22 Factors Affecting Process Efficiency. 24 Applicability to UOC BIOLOGICAL General Process Description. 26 Factors Affecting Process Efficiency. 26 Applicability to UOC summaRy of available treatment CHAPTER 4 - APPLICABLE TECHNOLOGIES FOR INTRODUCTION. 33 ACTIVATED CARBON General. 33 Process Description. 34 Operational Regulatory Considerations. 36 Estimated AIR STRIPPING. 39 General. 39 Process Description. 39 Operational Regulatory Considerations. 42 Estimated Costs. 43 i OXIDATION PROCESSES. 45 General. 45 Process Description. 45 Operational Regulatory Considerations. 48 Estimated COMBINATIONS OF PROCESSES AND SUMMARY. 51 SUMMARY OF APPLICABLE TREATMENT CHAPTER 5 - SUMMARY OF FINDINGS AND conclusions. 53 BACKGROUND. 53 FINDINGS. .
