What This Means for Growers
TRI facilities report annual chemical releases to air, water, and land. The primary pathway to gardens is airborne deposition — chemicals released to air settle on soil and plant surfaces, following Gaussian plume dispersion patterns. Risk is strongly wind-direction dependent: parcels downwind of a TRI facility face significantly higher exposure than those upwind or crosswind.
Leafy greens are most affected because they accumulate surface deposition on large leaf areas. Washing produce thoroughly reduces but does not eliminate airborne deposition risk. Crop selection (favoring fruiting crops over leafy greens) is an effective strategy near TRI facilities.
Crop Risk Assessment
Leafy greens
Large leaf surface area accumulates airborne chemical deposition; washing reduces but does not eliminate risk.
Root crops
Soil deposition from airborne releases can accumulate in topsoil over time, affecting root crops.
Fruiting crops
Fruit with peelable skins (tomatoes, peppers) have lower exposure — deposition stays on surface.
Tree fruits
Height above ground and bark barriers reduce exposure; wash all fruit before consuming.
Know Before You Grow — Mitigation Steps
- 1.Check prevailing wind direction — downwind parcels face higher exposure than upwind or crosswind locations.
- 2.Wash all produce thoroughly, especially leafy greens grown near TRI facilities.
- 3.Consider crop selection: fruiting crops (tomatoes, peppers) over leafy greens (lettuce, kale) in high-exposure areas.
- 4.Review specific chemicals released via EPA TRI Explorer — not all releases pose equal risk to gardens.
- 5.Row covers and hoop houses can reduce airborne deposition on crops.
