When rain falls or snow melts in Washington County, did you ever wonder where the water goes? Does it soak into the ground? Does it sit in puddles until it disappears? If you think the answer is yes, you are partially right. Some water does soak into the ground through pervious areas such as lawns, gardens, forests, and meadows, and some evaporates off hard surfaces and through plants. But not all rainwater is able to soak into the ground or evaporate.
