Ability to Meet Performance Metrics
:
Pay-For-Performance contracts require achievement of groundwater Cleanup Target Levels (CTLs) for BTEX, MTBE, PAHs and TRPHs (Residential CTLs - Chapter 62-777 F.A.C) and, importantly, maintenance of CTLs for 1 year with NFA recommendation.
Ability to Manage Rebound
:
In order to meet Maintenance of CTLs criteria, proper site characterization is important, but it is also critical to manage COI rebound (

Conventional ISCO technologies typically exhibit contaminant rebound, with one study showing that 75% of the conventional ISCO sites evaluated had no significant effect on benzene removal beyond that associated with natural attenuation (

In Situ
Chemical Oxidation at Colorado Sites). Fortunately, Provect-OX
® is specifically designed to support sustained bioremediation processes and therefore prevent rebound as iron will remain in place and active for many years (

Ability to Safely Implement at an Active Facility
:
Provect-OX
®
has fewer health and safety concerns as compared to use of traditional activation methods such as heat, chelated metals, hydrogen peroxide or pH extremes using NaOH. It will not generate excessive heat / off-gases. Single component product - all in one bag - with integrated buffer, ferrate-stabilizer and activator results in simplified logistics and application.
Performance
:
Promotes multiple oxidation reactions such as ferrate, superoxide and persulfate-based free radicals yielding more extensive
In Situ oxidation of a wider-range of organic contaminants (

Cost Efficiency
:
Local management and regional implementation plus significantly lower chemical costs due to utilization of multiple oxidants with combined secondary treatment processes. Use of ferric oxide conserves oxidant when compared to organo-iron or chelated iron activation.
