Bench Tests

Not sure where to begin with bioremediation? For the process to be effective, it’s vital to know which bacterial species (or bioremediating agent) to use at your site – and whether bioremediation will work at all. That takes unambiguous testing results.

At Novorem, we can test the response of your contaminated groundwater and soil samples to different stimuli before you make any decisions and commit to on-site injections for in-situ bioremediation.

How does bench testing work?

Essentially, bench testing is an analysis of your contaminated samples. Testing determines if the naturally occurring microbes in your sample are able to catalyse reactions that help or hinder bioremediation. You gain insight into whether a desired biological activity (such as hydrocarbon degradation) is naturally occurring, or if something present is inhibitory to it. We can test:

  • The addition of electron donors, acceptors or nutrients to your sample, and whether it results in a drop in harmful contaminants – a biostimulation test.
  • The effectiveness of commercially available hydrocarbon-degrading cultures and chlorinated-solvent-respiring cultures – a bioaugmentation test.
  • The results of different amendments when applied to a contaminated sample – a comparison test.

What the process looks like

  1. 01

    Testing chlorinated-solvent-contaminated groundwater

    Samples are incubated with candidate electron donors and organochlorine-respiring cultures, and monitored for dechlorination products and microbial abundance.

  2. 02

    Testing hydrocarbon-contaminated groundwater

    Samples are incubated with oxygen or nitrate as electron acceptor and nutrient amendments, and monitored for hydrocarbon loss and microbial growth.
