ISO 11504 has been updated. It’s titled Soil quality – Assessment of impact from soil contaminated with petroleum hydrocarbons. The new 2nd Edition is a technical update and replaces the previous 1st Edition from 2012. Both editions are available from Document Center Inc. in either paper format or for pdf download. They can also be provided as part of our enterprise custom collection subscription service.
ISO 11504 is a technical guideline for choosing the percentage and the types of petroleum compounds to look for when analyzing contamination of soils. This is the type of standard that will be used to determine if there has been soil contamination from the hurricanes in the southern U.S. Since petroleum hydrocarbons can be hazardous to human health, proper soil analysis is paramount.
Spotting these compounds can be a challenge when soil samples are taken to the lab. So this standard reviews how to make a number of critical choices for measurement and risk assessment. The ISO 11504 starts out with the usual scope, referenced documents, and definitions sections. Section 4 discusses the principles affecting this type of assessment – Time and distance, for example, can degrade the samples. So there are a number of factors that have to go into planning your testing.
Section 5 is on the relevant fractions and individual compounds. This is important since petroleum is composed of various components. And the types and percentage of hydrocarbons in a sample is the critical issue. Tables and text provide you with the detail needed.
Section 6 specifically addresses petroleum hydrocarbons in soil. Discussion on the composition and characteristics of crude and processed oils is enhanced by tables with information on the various petroleum mixtures, compounds, and their attributes. Section 7 then reviews the exposure element that affects hydrocarbons when present in soil.
ISO 11504 Section 8 covers additional issues related to the sampling and investigation. These issues range from preventing the loss of these volatile compounds in your samples to their proper storage and transportation. The document is completed by the addition of 3 informative Annexes. They discuss various physico-chemical properties of petroleum compounds, hazard level information, and an overview of suggested fractionations in various countries. A 38-item bibliography is also included.
