Any trees ok to plant near a well casing?

My front yard is not very big and I wanted to plant a small tree but the well is located in the front yard. I have read that maples and weeping willows could harm your well and septic. Is it safe to plant a tree near the well? I was looking at something like a dogwood, weeping cherry, flowering crab apple or forest pansy. Would any of these be safe? Is there something else that would be better? I am open to any suggestions. Thank you for your info!
