Metolachlor
Metolachlor is a synthetic organic compound used as an herbicide to control grassy weeds on agricultural crops like corn and soybeans. It is known commercially as Bicep or Dual. It works by preventing the weeds from synthesizing long chain fatty acids that they need to survive. Metolachlor can bind to soil particles or leach through soil and enter groundwater depending on a variety of factors, including soil composition and precipitation. It has been detected in surface water and groundwater. Metolachlor and its degradates (metolachlor ESA and OXA) can remain in soil and water for months before they are fully broken down.

Health Effects
Health protective benchmarks for metolachlor are based on potential adverse developmental effects. The EPA classifies metolachlor as a possible human carcinogen.
Affected Organs & Systems:
Common Sources
- Metolachlor is not naturally occurring, so its detection in the environment and drinking water sources is a result of human activity. It may enter the environment through industrial effluent, runoff from places where it is discarded, manufactured, or stored, and runoff from places where it was used as an herbicide.
How to Remove It
Water filters certified under the following NSF standards are effective at removing Metolachlor:
EPA MCLG Level
The EPA MCLG represents the maximum level that poses minimal health risk based on the latest scientific research. It's often more protective than federal legal limits.
Contaminant Type
Metolachlor is classified as a Herbicides contaminant.
This contaminant primarily affects the developmental.
