A Baraboo woman says chemicals from a car wash next door are running downhill into her yard and have killed several trees. Samantha Langer says she has asked Viking Car Wash to fix the problem.  The car wash owner says some dirt will be used to create a berm so the water flows away from Langer’s property.  Scientists will test the soil near Langer’s trees for phosphorus, sodium and salt.  While the testing is done, she says more trees will have to be taken down.
