California Restricted Material

A pesticide subject to California restricted-material requirements, supported by a county permit or another official source.

Federal Restricted Use

Classified by the U.S. EPA for use by, or under the direct supervision of, a certified applicator.

DPR Water Protection List

On DPR’s official Groundwater Protection List, 3 CCR section 6800, effective July 1, 2026. DPR identifies these chemicals as having the potential to pollute groundwater. This current listing is shown alongside historical application records.

Environmental concern

A sourced finding about soil mobility, aquatic toxicity, runoff or persistence.

Label hazard

A product label’s DANGER or WARNING signal word, protective equipment requirement, buffer or aquatic-use restriction.

Aerial

Applied from a helicopter or aircraft. This describes the application method.

A groundwater listing is separate from restricted-material status and does not establish contamination or a violation at a particular site. An application with no flags has no recorded flag; that does not establish that it is harmless.
