I’m currently trying to build hugelkultur mounds and have random areas of dirt in my woods. Me and my spouse were planning to dig in the dirt and apply this dirt to my mound. I’ve been warned that these mounds may be from them making creosote poles on my property. I’m sure it’s been at least 40+ years but should I get this dirt tested for contamination and if so where? I’ve contacted my county extension agent and they don’t test for contamination. Btw I live in NC where there is a big presence for agricultural education.
