This application note describes a fast and reliable way to extract organochlorine pesticides (OCP) from soil with the SpeedExtractor E-916. After reducing the volume with the Syncore Analyst the extracts were cleaned by using Florisil. The cleaned extracts were concentrated again and quantified by GC-ECD. The measurements are within the prediction interval (P.I.) at least 19 out of 20 times. Out of the 22 quantified values only one value was above the P.I. All pesticide values in the blanks were below the limit of quantification.

`Standards are desperately needed for plastic and pesticide contamination in soil´
In addition to plastic in the oceans, plastic contamination in arable land throughout Europe and other parts of the world is a growing problem. No standards exist for these types of soil pollutants, nor for pesticide residues or their degradation products. For this reason, Professor Violette Geissen is calling for standards to be implemented. On 15 June, Geissen will deliver her inaugural address as professor holding a personal chair at Wageningen University & Research. Plastic covers are used in agriculture...
How To Complete A Soil Test The Right Way
A soil test should be one of the first steps you take in your landscape plan. Many of us never take this important first step, which contributes, to wasted resources and wasted time. The U.S. Department of Agriculture says soil testing is an “essential” tool that provides information on fertility and pH. Testing also indicates what amendments you should add to increase productivity of your soil. Without a soil test you may be spending money and time on adding the wrong or too much of a specific...
Soil and Ground Water Remediation Case Study
On this State Funded Clean-Up project, Global was the project engineer and was responsible for the design of an air sparging/soil vapor extraction remediation system. The system included five soil vapor extraction wells and twelve sparging wells that operated on a rotating schedule. One of the soil vapor extraction wells and nine of the sparging wells were installed as horizontal wells beneath M-72 usingdirectional drilling method. Global designed the system, prepared the plans and specifications, oversaw bidding...
White Paper: Soil Data Quality Control
Why it is essential during a contaminated soil study? Before starting an evaluation of the contamination leading to decision-making tools for site clean-up, it is essential to ensure data quality. Thus, based on solid and reliable foundations, uncertainties occurring during the different steps of the decision process will be better controlled and the final quality of the project improved. The objective of this white paper is to assess at best the validity of the data through visual, statistical and geostatistical...
