Revisions for Making meaning of soil test results and reports

4 CURRENT	laurel_mire	June 30, 2021 23:42 \| almost 3 years ago If you’ve given soil samples to a lab for contaminant testing and received the results, one of the next steps is to interpret the results and make meaning of them. You might have a short document listing test results from the lab, or a longer report that includes some summarizing and recommended actions. Please contribute to the resources below by editing this page or adding and answering questions! You can also follow along and get updates on this topic by subscribing to the interpret-soil-tests tag What’s on this page: Guides and activities to try from the Public Lab community about interpreting the results of soil testing Activities Some notes on terminology Examples sources for health-based standards More background on technical documents and standard documents Questions about interpreting soil testing results Additional resources and guides Getting technical support Guides and activities to try Here are some resources and activities that can help you understand the kinds of information in soil test results and how to interpret them. Some of these activities explain how community members can work together on reviewing documents. Activities [notes:grid:activity:interpret-soil-tests] These activities involve comparing the measured amounts of chemicals reported in your results to health-based standards or screening levels set by a government agency. The standard level is the amount of chemical over which there might be concerns, and more detailed testing would probably be helpful. “Health-based” means that the standard considers potential impacts on human health. Some notes on terminology When looking for standards to compare your soil test results to, you might see words like screening levels, target levels, cleanup objectives, and others. Below is some information on how those terms can mean different things. In a survey of regulatory agencies in several states across the US, here’s how the states usually defined terms (paraphrased from pg. 44 of this document): Screening level: “a level that provides information on whether additional evaluation of a specific chemical in a medium is required.” Cleanup goal: “most states indicated that this related to the level at which no further remediation would be required.” Target level: “either a chemical level in a given medium that is protective of human health, or an acceptable risk level (e.g., a specific cancer risk and/or HQ [hazard quotient]).” From: ITRC (Interstate Technology & Regulatory Council). 2005. Examination of Risk-Based Screening Values and Approaches of Selected States. RISK-1. Washington, D.C.: Interstate Technology & Regulatory Council, Risk Assessment Resources Team. For more information about screening levels, this section) explains what screening levels are and how they relate to human health. Example sources for health-based standards As mentioned in the posts above, standard levels can vary by city, state, country, and agency. In “How to interpret soil test results,” you’ll find a table comparing standards from different regions and agencies for various contaminants. Your soil test results or report might already list local standard or screening levels next to your results. If not, here are some different sources for standards: New York State Soil Cleanup Objectives (SCOs) Brownfield Cleanup Program: Development of Soil Cleanup Objectives - Technical Support Document Soil cleanup objective levels for unrestricted land use start on pg. 345. Restricted land uses, including residential, start on pg. 349. US Environmental Protection Agency Regional Removal Management Levels (RMLs) User's Guide You can download tables of RML values here. Look for the concentrations in the “Removal Levels” column on the right for residential soil or industrial soil. ETOX: Information System Ecotoxicology and Environmental Quality Targets The ETOX database “contains information on various national and international environmental quality guidelines, targets, standards, criteria, and limit values.” Search by “Substance” on the left-hand menu to see entries for that chemical. Click on an entry and you’ll see on the right-hand menu “Quality targets,” which lists that chemical’s standard levels for soil and water in different countries. It’s not an exhaustive list, but it’s a source for some international standards. More background on technical documents and standard levels [notes:grid:interpret-results-intro] Questions Questions from the Public Lab community tagged with `interpret-soil-tests` will appear here [questions:interpret-soil-tests] Additional resources and guides Understanding Results, from the Healthy Soils, Healthy Communities project at Cornell University’s College of Agriculture and Life Sciences.

Comparison of International Risk-Based Screening Levels. Proceedings of the Annual International Conference on Soils, Sediments, Water and Energy. Vol. 15 , Article 24. See pg. 295 for a table comparing screening levels from different countries for various contaminants, including heavy metals (lead, arsenic) and organic pollutants (benzene, PCBs).
