Closure Analyses

As each site is judged not to require remediation or if it does, approaches the completion of the process, it is necessary to obtain "Closure Data" to document that the site requires No Further Action. ESN labs routinely generate data adequate for use as Closure Data. It is legally defensible, and incorporates sufficient QA/QC to meet any State or Federal guidelines and requirements. Such data are generated in both mobile and in-house laboratories.
