On Monday, April 18th, representatives from the Environmental Protection Agency (EPA) visited Pop! Farm with Parks & People to announce new environmental justice grants and to celebrate the lead testing program they sponsored, performed together with Parks & People's Branches program. The EPA's program supported lead testing in urban sites, like Pop! Farm. Pop! Farm's lead levels were shown to be elevated, but below the limits set by the EPA, making it a safe place to grow fruit and vegetables.
Lead gets into the soil by the process of adsorption, which basically means that the lead atoms stick to the surface of soil particles. If someone breathes in this soil or eats food that is contaminated, the lead is able to get into their body. The main sources of lead, which are lead-based paint and gasoline, are no longer used, but lead can persist in the environment for 30 years or more. To learn more about the dangers of lead, visit the EPA's Lead page.
