We utilize a variety of low-flow purging methods to sample groundwater at PCB-impacted sites. The method used depends on the demands of the site and the requirements of the client. Our personnel will purge groundwater from monitoring wells and determine its characteristics (temperature, conductivity, dissolved oxygen, oxygen reduction potential, pH, and turbidity) to determine the proper course of action for PCB-impacted groundwater remediation.
To preserve sample integrity, our equipment will be decontaminated between sampling locations using approved detergents and decontamination procedures. Furthermore, samples collected onsite will be immersed in an ice bath immediately after collection. Afterwards, our samples will be shipped to an approved laboratory at 40 C in properly labeled, approved containers under chain of custody.
All wastes generated during sampling and monitoring will be properly handled onsite before offsite transport. Wastewater can be stored in 55-gallon drums or polytanks of varying volumes. We will also manage wastewaters generated onsite and determine the proper disposal method for bulk product and miscellaneous wastes. All wastes will be properly labeled both onsite and during offsite transport in accordance with DOT requirements.
