The appropriate selection and use of these methods can resul

20、t in increased spatial site information in less time and with fewer phases of assessment than is typical using conventional sampling methods and off-site laboratories. There is some reluctance to using field analytical methods because of the lack of regulatory acceptance and the perception that fiel

21、d methods do not provide data of adequate quality for making decisions. This report makes no recommendations, but presents a decision-tree approach for selecting and using field analytical methods. This approach will assist the user in the generation of higher- quality field analytical data by promp

22、ting selection of the appropriate method for the sites investigation goal. Quality assurance guidelines specific to the desired data quality level are also presented, to increase the credibility of the data by documenting method performance. The report also provides training suggestions and easy-to-

23、use checklists for field quality control and formal documentation. STD.API/PETRO PUBL Yb70-ENGL 1998 E 0732290 Ob3333755 791 9 TABLE OF CONTENTS EXECUTIVE SUMMARY . e5-1 1 . INTRODUCTION . 1-1 2 .

33、oughout the environmental remediation industry, there has been a drive to reconcile the time constraints and regimentation of “phased” investigations that occur in discrete steps, with a more fluid process of continuous sampling, analysis, and real-time decision making. This has been the case for pe

34、troleum product release sites, where a great deal is now known about the hydrocarbons involved and the specific indicator constituents of concern. This publication presents a different approach, through a Decision Tree, for the selection of appropriate field methods for the on-site testing of petrol

35、eum compounds in both soil and groundwater, which would be a key part of accelerated site characterizations (ASCs). The manual addresses the primary constituents of petroleum fuels benzene, toluene, ethylbenzene, and xylenes TEX); total petroleum hydrocarbons (TPH); polynuclear aromatic hydrocarbons

36、 (PAHs). The methods selected for inclusion in the flow charts are mature, off- the-shelf technologies that measure these constituents. There are other technologies more recently available for these constituents and for constituents not included (e.g., metals). However, alternative methods and other

37、 non-petroleum constituents can also be considered within the context of the Decision Tree approach. A unique decision process flow chart (Section 2) is designed with “decision steps,” to assist the site manager and regulatory remediation project managers with a tool to more efficiently manage the o

38、ptimization of analytical data in the field, and to help determine the appropriate level of data quality (LDQ) needed for the job at hand. The analytical field method selection process is, therefore, job oriented and incorporates practical factors such as investigative goals, regulatory requirements

39、, data quality needs, sampling media, and constituents of concern. The Decision Tree charts are supported by quality control packages (Appendix D and Section 5). These packages contain 1) suggested quality controls in a checklist form, and 2) documentation ES-1 STD.API/PETRO PUBL 4b70-ENGL 1998 0732

40、290 Ob11759 337 log sheets. This format is designed for ease-of-use in the field, and the forms can be attached to project reports. An important part of the data optimization process, and a key advantage of on-site testing, is the opportunity for an iterative, or constant feedback approach, i.e., to

41、 repeat the sampling - evaluation process in the effort to get successively closer to desired results or goals. A version of an iterative sampling approach is illustrated in Section 3. Finally, the minimum recommended training for personnel who will perform the testing in the field is described in S

42、ection 4. Overall, the best approach to maximize the usefulness of the investigative data produced on site is to use this manual in combination with NIS sister publication, Compilation of Field Analytical Methods, Publication No. 4635, and with other references noted in the Introduction of this manu

43、al. Additionally, the manufacturers are a worthwhile source of information on applications, background chemistry, and best practices for their products. ES-2 STD.API/PETRO PUBL 9670-ENGL 3998 W 0732290 0633760 059 = Section 1 INTRODUCTION OBJECTIVE This publication complements the API publication (D

44、ecember, 1 996), Compilation of Field Analytical Methods for Assessing Petroleum Product Releases, in which operation, practical applications, and limitations of the most widely used field analytical methods are discussed. In this publication, a Decision Tree is developed to assist project or site m

45、anagers with guidance for on-site investigations of suspected or confirmed hydrocarbon release sites, fiom an initial site assessment to site closure. The Decision Tree is complemented by method-specific quality assurance/quality control (QNQC) protocols designed for the evaluation of quality, viabi

46、lity, and defensibiliw of field analytical data. Briefly, the objectives for this technology selection guidance document are: 1. To provide guidelines for field analytical technology selection and use on-site, through a Decision Tree or “Decision Flow approach; 2. To assist in generating analytical

47、data of known and consistent quality through method- specific QNQC protocol packages; 3. To assure that the method sensitivity, accuracy, and precision meet the decision-making needs of the project or site manager, the client, and the regulatory agencies; and 4. To guide the regulated community in p

48、roducing consistent and defensible field documentation and training for field personnel. BACKGROUND The use of field analytical methods for investigations of petroleum hydrocarbon release sites has gained broader attention in recent years as part of more cost-effective, single mobilization site asse

49、ssments. This increasingly popular concept has been discussed as Expedited Site Assessment (ESA) by the U.S. Environmental Protection Agencys (EPAs) Office of Underground Storage Tanks (UST), as Accelerated Site Characterization for Confirmed or Suspected Petroleum Releases in the ASTM PS 3 guide, as Expedited Site Characterization by the Department of 1-1 STD.API/PETRO PUBL 4b70-ENGL 1994 0732290 Ob1L7bL T95 Energy, or as Expedited Site Closure Approach (ESCAB) by Land Tech Remedial, Inc. All of these single mobilization site assessment concepts have in commo
