Sampling Resources

To ensure that the proper sample volumes are provided for laboratory analysis and that regulatory requirements are met regarding proper sample containers, preservation and temperature an Environmental Sampling Guide is available. The EPA method for each analysis is included for your use and EPA holding times are also included in the table for your reference.

PSS also has some consumable sampling supplies available for purchase including: gloves, pH buffer solutions, DI water, Alconox, single use bailers for groundwater sampling, pre-cleaned tubing for TO-15 sampling and other useful items. PDF’s and interactive chain of custody forms are available for your use.

In observance of the Thanksgiving holiday, the laboratory will be closed on Thursday, November 27th and Friday, November 28th 2025. We ask that all samples be submitted by 12pm on Wednesday November 26th. Please contact a PSS project manager prior to submitting samples with short holding times or that require a quick turnaround time, so that we have the opportunity to ensure your needs are met. If you have any questions, call 410-747-8770 or email info@phaseonline.com. Have a safe and happy Thanksgiving holiday! – Your Phase Team.
