We’ve been hearing a lot of mixed results on pesticide remediation, mostly anecdotal, so we decided to run controlled tests on some of the most commonly flagged pesticides and see how different media actually performed.
We ran spiked samples through Media Bros’ G-CRAC, CRAC, Magsil (Magnesium Silicate that has a lower activation temperature than Magsil-PR®), and Carbon Chemistry’s Magsil-PR®, testing them in n-heptane, 190-proof ethanol, and 200-proof ethanol, and then sent everything to a 3rd-party lab for validated analysis. A few takeaways:
-
Carbaryl (super common failure): Media Bros’ CRAC and G-CRAC both showed solid reduction when paired with hydrocarbons.
-
Chlorfenapyr: Tough one. Media Bros’ G-CRAC in n-heptane gave the best numbers — better than we expected.
-
Pyrethrins: More responsive to ethanol systems. 200-proof EtOH with CRAC or G-CRAC dropped it under state limits in some tests.
-
Myclobutanil: Carbon alone didn’t cut it — solvent choice mattered way more than media type.
We also broke it all down by state (AZ, CA, CO, MA, MI, MT, NV, NY, OR, WA), since each one’s pesticide panel and allowable limits are different. So if you’re in Oregon, Colorado, or Michigan, etc.., you can literally find a table that shows the results for your specific testing range.
This isn’t “trust the process” talk — it’s real data from controlled remediation runs.
