MiningAgricultural Pesticide Use in Nevada
In the 2019 federal survey estimates, Nevada's most-applied agricultural pesticides statewide were Glyphosate, 2,4-D and Chlorpyrifos. These estimates describe agricultural land use across the state — context for what's in use around the region, not a reading on any garden's soil.
Pesticide data: USGS NAWQA Pesticide National Synthesis Project (EPest county-level use estimates). Latest available county estimates: 2019.
County-Level Detail in Nevada
The federal record isn't uniform across a state. Here's what's documented around Nevada's counties with the densest records — each read from that county's own sites, not the state average. Proximity is information, not a diagnosis; a soil test settles any near neighbor.
Is It Safe to Grow Food in Carson City?
Federal record: HighWe checked the federal record around Carson City — 577 documented sites across 8 of the 9 source types we track, 27 of them high-severity.
The most significant on record: 8 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Carson City carries one of the heavier federal records we track — 577 documented sites, most of them nitrate. That's a record of the area's history, not a verdict on any one yard: proximity to a documented site is information, not a diagnosis. Before food beds go in, a professional soil test tells you exactly what you're working with — and raised beds with clean imported soil grow well almost anywhere in the meantime.
