We introduce the VacuSIP, a simple, non-intrusive, and reliable method for clean and accurate point sampling of water. The system was developed and evaluated for the simultaneous collection of the water inhaled and exhaled by benthic suspension feeders in situ, to cleanly measure removal and excretion of particulate and dissolved compounds.

This protocol describes the use of a tangential flow hollow-fiber ultrafiltration sample concentration system and a heat dissociation as alternative steps for the detection of waterborne Cryptosporidium and Giardia species using EPA Method 1623.
FAQs
Minimizing headspace reduces the volume available for volatile compounds to leave the sample and accumulate outside the liquid portion. That helps limit evaporation before laboratory analysis, preserving a specimen that more closely represents the collected environmental material. This control is particularly important when measurements target volatile organic compounds, where sample loss could affect reported concentrations.
Chemically resistant glass provides the primary container surface, while the cap and septum create a tight closure. Together, these components help limit contamination, evaporation, and chemical reactions during storage and transport. Their combined function matters because preserving the sample requires both a suitable container material and a seal that remains secure through the laboratory workflow.
Temperature control is one part of maintaining sample integrity between collection and analysis. Keeping the sample under appropriate temperature conditions, along with proper filling and sealing, helps preserve the specimen during transport and storage. This matters because laboratory results are intended to represent the collected sample, not changes that occurred before testing.
Vial selection is part of matching the container to the sample and the intended laboratory analysis. Using an unsuitable container can undermine the preservation strategy even when labeling and transport are correct. In environmental monitoring, appropriate selection supports reliable measurements across drinking water, wastewater, soil, and hazardous-site specimens.
A reliable workflow includes selecting the appropriate vial, filling it correctly, minimizing headspace when volatile organic compounds are involved, sealing it tightly, labeling it, and maintaining temperature control during transport. Each step supports sample integrity at a different stage, reducing the chance that handling conditions will compromise the laboratory measurement.
These containers support testing of drinking water, wastewater, soil, and samples from hazardous sites. Their use allows laboratories to analyze pollutants from different environmental settings while applying consistent collection and preservation practices. That consistency helps monitoring programs compare measurements with environmental quality standards and supports defensible regulatory assessments.
By helping preserve samples until laboratory analysis, EPA vials support measurements that are more representative of the collected material. Reliable pollutant measurements allow results from drinking water, wastewater, soil, and hazardous sites to be compared with environmental quality standards. Proper selection, sealing, labeling, and temperature control strengthen the defensibility of those comparisons.
