You will find these codes used throughout the report in headers and in note <br /> sections to designate a unique fact about the data to which they are associated <br /> The Case Narrative gives a"story" about the analysis and results. Here you will find greater elaboration on relevant qualifiers as well as an <br /> explanation of anything of particular note in the data. This is a discussion of the data in terms of quality control and chemistry. It is a summary of <br /> any deviations that could affect the usefulness of the data. This is not an interpretation as to how this information relates to regulatory compliance, <br /> toxicity,or hazardous characterization. These items are beyond the scope of this report <br /> The Sample Summary provides detail on sample receipt The association between Client sample ID and the Laboratory sample ID aze defined here; <br /> this information is valuable to have when discussing results with your project manager. Sample collection and receipt dates and times are provided <br /> here as well. General notes regarding the work order aze also documented here. This is a mini "case narrative"that describes any anomalies <br /> regatding the condition of the samples upon azrival to the laboratory or special circumstances regazding the work ordea <br /> The Conditions Upon Receipt summazizes the results of specific checks that have been performed at sample receipt. This includes items like <br /> custody documentation,sample condition,and temperature at receipt Each"cooler"is identified and the conditions associated with that cooler are <br /> documented. A"cooler"is defined as the larger container used to transport the individual samples. In most cases this is a standard recreational <br /> cooler but it can be a box,plastic bag,or other container. <br /> The laboratory results are summarized in the following sections. Data is broken down into major categories for convenience. An example of such <br /> a category would be "Total Petroleum Hydrocarbons." Here you would find data that references the testing of such pazameters as diesel range <br /> organics and gasoline range organics. Other categories are similarly mapped The batch number is associated wiffi each sample. This is important <br /> to evaluate Quality Control (QC) data. Surrogate results samples aze provided with each sample. Laboratory control limits are provided for <br /> comparison(see below). The reference method is also identified. If a method is denoted with an"M"(e.g.EPA 1234(1�)this means that it has <br /> been modified An explanation of the modification will be found in the Case Narrative. A result is given with appropriate units. If a soil sample is <br /> dry-weight corrected then the word"dry"will appear next to the units. If the word"dry"does not appear then the result is "as received." <br /> T'he Method Reporting Limit(MRL)is provided. It is important to understand this term. The MRL is a level that has been empirically verified to <br /> provide reliable quantification of results. Results that are equal to or greatet than this value will show up as bolded They are considered"hits." If <br /> a result is less than the MRL,the result is given as less than the MRL(e.g.if the MRL=10 then a less than would be given as"<10"). <br /> The Quality Control (QC) samples are documented in the following section. Here you will find the preparation batches associated with each <br /> sample from the results section. T'he sample preparation method is also defined here. Accuracy is represented in terms of a percent recovery as <br /> compazed to a known value. Precision is represented as a relative percent'difference between two duplicate sample atiquots. The laboratory <br /> control limits are provided as a means to evaluate the quality control data. If the result fa11s outside the laboratory control limits this simply means <br /> that it is ouEside what is typical for the laboratory and is noted accordingly. This does not mean that the data is invalid. Laboratory control iimits <br /> are generally tighter than most program limits. This is a very important distinction. How the data is ultimately used determines its validity. <br /> Program requirements are defined in the Quality Assurance Project Plan(QAPP)governing the project. If your project manager is aware of your <br /> specific program requirements then a note will be made in the case narrative if the data fails to meet any of these requirements <br /> 'I'he last section contains copies of important documents and/or instrument printouts relevant to the report. 'This includes the chain of custody. It <br /> also may include items like chromatograzns or spectra <br /> Please note that this report is paginated and must be reproduced in its entirety. <br /> EPA Lab ID:MN00063 The results in this report apply onTy to the samples analyzed in accordance with the � <br /> chain of custody document.This analytical report must be reproduced in its entirety.
