QuantArray®-Chlor: Actionable Data for Remedy Selection

• Site managers were considering monitored natural attenuation (MNA), biostimulation, and bioaugmentation as remediation strategies at a site impacted by a complex mixture of chlorinated hydrocarbons including PCE, TCE, 1,1,2-TCA, 1,2-DCA, cis-DCE, and VC along with high concentrations of sulfate.

• QuantArray®-Chlor analysis provided actionable data for remedy selection allowing timely decisions and significant cost savings in site management.

SIP: Evaluating MNA at a Manufactured Gas Plant

– Site stakeholders needed conclusive evidence that biodegradation of benzene and naphthalene was occurring under existing site conditions to accept MNA instead of a more aggressive strategy.

– Stable isotope probing (SIP) studies using Bio-Traps® amended with 13C benzene or 13C naphthalene conclusively demonstrated in situ biodegradation occurred under existing site conditions.
