Microarrays also obtain genetic information from microbes in soil or water, and while less quantitative than qPCR, this method can analyze tens of thousands of genes at once.

An environmental remediation team could use qPCR to count the population of specific contaminant degrading microbes, or to assess the genetic biochemical pathways (e.g. microbial cellular machinery) that cause the degradation of environmental contaminants.
