How to Get Rid of Roundup in Soil – Glyphosate Removal

We’ve gotten a lot of interest lately in how to get rid of roundup in soil. Roundup has an active ingredient of glyphosate and has been in the news a lot of late.

Let’s remember that Roundup is used as a weed killer or herbicide. It is one of the most widely used weed control chemicals on the market today. It’s used on farms and on residential yards.

The Problems with Roundup

Well there are a bunch of problems with Roundup. Here’s one of the best summation of the problems that I have seen from the Ecology Center website.

  • Glyphosate, the active ingredient in Roundup, is the third most commonly-reported cause of pesticide illness among agricultural workers in California.

  • Glyphosate is the most commonly reported cause of pesticide illness among landscape maintenance workers in California.

  • The surfactant ingredient in Roundup is more acutely toxic than glyphosate itself and the combination of the two is yet more toxic.

  • Glyphosate is suspected of causing genetic damage.

  • Glyphosate is acutely toxic to fish and birds and can kill beneficial insects and soil organisms that maintain ecological balance.

  • Laboratory studies have identified adverse effects of glyphosate-containing products in all standard categories of toxicological testing.

  • Glyphosate residues in soil can persist over a year.

  • Glyphosate residues has been found in strawberries, wild blueberries and raspberries, lettuce, carrots and barley.

  • Glyphosate has been measured 1,300 – 2,600 feet away from its application site.

  • This year Monsanto, manufacturer of Roundup, agreed with the New York Attorney General’s office to discontinue their use of the terms “biodegradable” and “environmentally friendly” in ads promoting glyphosate-based products, including Roundup.

Roundup in Soil

Since roundup ends up in the soil, that where we need to take care of the problem. It turns out that microorganisms, our soil heroes, are quite good at breaking up and degrading Glyphosate.

However, if you do not have a thriving microbial soil population or if you suspect that the natural microbes have been killed by Roundup, you should consider adding them. The addition of soil microorganisms will prove beneficial to your soil.

How to Get Rid of Roundup in Soil

Roundup can be removed from soil by use of microorganisms. Removal of soil contaminants by using microorganisms is called bioremediation. 

Below is a test using Custom FM, a bioremediation product of Custom Biologicals.

Here’s a bench scale test of the biotreatability(bioremediation) of Roundup, glyphosate, using Custom FM. We used Custom FM because in this instance we were treating contaminated water.

Laboratory Results

Client: Wastewater Plant Manufacturer

Description: Bench scale bioremediation evaluation and biotreatability testing of Custom FM

Chemical: Glyphosate

Class: Herbicide

Brand name: RoundUp

Manufacturer: Monsanto


  • Active ingredient is 0.96% (less than 1%).
  • Wash water wells are 1000 gallons average.
  • A spill of 1 gallon into the water well would equal 9.6 ppm
  • 9.6 ppm (parts per million) = 9,600 ppb (parts per billion)
  • Initial contamination was calculated at 9,600 ppb.

Detectable Limits: 10 ppb

Test Duration: 21 days

 Results Before and After Treatment 

Before                                                            After

Sample #1 9,600                                         BDL

Sample #2 9,600                                         BDL

Sample #3 9,600                                         BDL

units are in ppb (parts per billion)

BDL is Below Detectable Limits
