North Wildwood - Would anyone know what was in the water that was pumped from the ground at the house putting a swimming pool in North wildwood ? Why did the city have the curb pressure washed where the water ran to the storm sewer on NJ Ave. And who is paying for the clean up? It has to be something really bad and expensive because the city truck is sucking the water out of the sewer as it is pressured washed in to it so it does not go into the bay
