Acquiring a sample from a discrete location without the active media transport induced by pumping or purge techniques (ITRC 2023). Passive sampling bypasses the stagnant casing water and acquires a representative groundwater sample from an interval in the saturated screen without purging the well. Are passive groundwater samplers more efficient than typical low flow or volumetric purge methods? Yes! Because you don’t have to purge the well or wait for parameters to stabilize, passive sampling is easier and much more efficient than active sampling methods. Consultants share their experiences with us and consistently refer to cutting their sampling time by 50-80%. Does passive groundwater sampling provide consistently accurate results? Yes! Numerous third-party field studies and lab-controlled bench studies have been conducted since passive sampling in groundwater began over 25 years ago. The overwhelming evidence is that passive sampling does provide accurate results for groundwater sampling. Click here to see studies How much money can passive groundwater samplers save on a project? Cost savings depend on many factors, including number of wells, frequency of sampling, type and amount of purge-water, and the sampling method that passive sampling will replace. A study conducted at McClellan AFB in 2005 showed that the sampling cost was ~$250 less expensive (80%) per well / per event when comparing passive sampling to pumping methods. A 30-year monitoring program with a 20 well network sampled semi-annually, will save $300,000 by converting to passive sampling! Click here to see study . What types of projects are passive samplers suited for? While passive samplers can be used in any groundwater monitoring project, they provide the most benefits when used on long term monitoring projects with two or more sampling events per year. Due to volume limitations within groundwater wells, the benefits of passive samplers are less practical if you need to sample more volume than is held within the saturated screen portion of the monitoring well. Do regulators approve passive sampling? Over the 25+ years since the USGS introduced passive groundwater sampling, regulators have approved passive sampling on projects at federal, state, and private sites in all USEPA regions including, Superfund, CERCLA, and DoD sites. There are many individual regulators, each with their own background and experience, and some regulators are unfamiliar with passive sampling or hesitant to change sampling methods without more information. EON always recommends approaching your regulator for a discussion about the project benefits of passive sampling, and we can provide technical information, case studies, and SOPs so that nobody feels like they are trying something new! What training is needed to learn to use passive samplers? Passive sampling is extremely easy and requires very little training! EON takes pride in our hands on approach to training new users. We provide free virtual training on all of our passive samplers: including how they work within the monitoring well and the deployment/recovery process for sampling. EON will partner with you to ensure you enter into your first passive sampling event prepared and confident. What are the different types of passive groundwater samplers? There are two main types of passive groundwater samplers that function differently but have the same general benefits of cost reduction, ease of use, and they do not produce purge water. Passive Grab Samplers, capture a whole-water sample at an interval in the saturated screen. The water and everything in the water (including PFAS) are recovered without inducing flow in the well that could cause mixing with stagnant well water. The HydraSleeve is the most-used passive grab sampler. See Video Here . Passive Diffusion Samplers collect a water sample containing contaminant molecules that have diffused through the pores of a semipermeable membrane filled with deionized water. The contaminant concentration in the sampler reaches and maintains the same concentration as the surrounding water.
