Passive Sampler for Water-Soluble Compounds

The ideal passive sampler for determining concentrations of many analytes, including metals, dissolved organic carbon, phosphorus, major anions, and other water quality parameters.

Breathing New Life into a Mature Technology

SiREM’s SPeeper is a comprehensive, passive sampler and interpretation service for measuring water-soluble compounds in sediment porewater, surface water, and stormwater. It is the ideal tool for determining concentrations of many analytes, including metals, dissolved organic carbon, phosphorus, major anions, and other water quality parameters.

Dialysis passive samplers (peepers) were developed over 45 years ago to address the complications associated with mechanical porewater sampling protocols for dissolved inorganics. SiREM’s SPeeper™ sampler can be scaled to measure several analyte classes at various sediment depths with a customized 3D printed frame to make deployment and retrieval easy while keeping the impact on the surrounding geochemistry of sediment and porewater to a minimum.

SPeeper Samplers Provide Off-theShelf, Comprehensive Solutions

  • Durable, field tested, ready-to-use onsite.

  • Diverless deployment and retrieval options to reduce costs and speed up field deployments and retrieval.

  • A reverse tracer for determining equilibrium conditions of each individual sampler.

SPeeper Samplers Are a Cost-Effective Solution

  • Measures only dissolved analytes (not precipitated or adsorbed species), offering an improved understanding of compound mobility and environmental risk.

  • Reduces risk of contamination and overestimation compared to other traditional sampling techniques.

  • Saves money by reducing unnecessary investigation, remediation, and management costs.

SPeeper Samplers Are a Decision-Making Tool

  • Passive sampling provides critical data to help decision makers design remediation strategies. Data provided via passive sampling informs the following: 

    • Better understandings of fate and transport of chemicals 
    • More accurate identification of toxicity 
    • Better decisions about monitoring, including enhanced stormwater and effluent monitoring 
  • SPeeper is accepted by USEPA and state regulatory agencies.

  • SiREM is listed as a service provider in USEPA passive sampling guidance.  

  • Results on a dissolved-phase basis (e.g., nanograms per liter [ng/L] porewater) in an easy-to-interpret reporting format
