A system, method, and devices for remediating soil of an area of land. The devices are partially inserted into the soil within the area. The devices have vent holes fluidically coupling each device to the soil. A hot fluid is circulated through the devices to heat the soil in the area to a temperature sufficient to cause a transformation in the soil. The transformation may transform an environmental contaminant in the soil such that a gas is generated from the transformation, and the gas is sucked from the soil into the devices via the vent holes and the out of the devices away from the soil. The transformation may cause a bioremediation of an environmental contaminant in the soil such that a product is generated from the bioremediation, and a bioremediation fluid is injected into the devices and into the soil via the vent holes to facilitate the bioremediation.
