Agricultural contaminants
33. Agricultural contaminants
Exposure to herbicides, pesticides and fertilizers that enter the water supply from agricultural and stormwater runoff has been linked to kidney, liver, gastrointestinal and reproductive health issues. While these are typically not found in high enough concentrations to cause acute health problems, they can be difficult to contain and remediation strategies often require action at the municipal and industrial level.
This feature calls for the responsible management of herbicide, pesticide and fertilizer usage to help limit leaching into water sources. This feature also sets maximum safety limits for common pesticides and herbicides detected in indoor drinking water. If detected, these contaminants can be removed with carbon filters.
