We hired Environmental Works for our initial sewer scope and oil tank soil tests while inspecting this home that we purchased. They did a great job with the scope, so we hired them to decommission our oil tank as well. They scheduled the service for May 29th at 8am. Call me naive, but this gave me the impression that the oil tank would be completed that day. The service men showed up on time, got to work, and seemed to do a great job with removing the old crud from the tank. I was terribly surprised to show up the next morning, and see that a giant hole had been left in our yard where the oil tank is. The hole was covered with a flimsy, half-rotting piece of plywood, and some orange plastic fencing was rigged up around it. I called Enviro Works, and was told that there was no way that they would finish an oil decommission in one day. They always needed to inspect the bottom of the tank for leaks, and they would do additional soil sampling around the bottom of the tank to verify that no leaking had taken place. There's always a delay between draining the tank, doing the tests, getting the test results, and then finishing the work. This was all news, and all a surprise to me. We had a lot of contractors and a lot of work going on at this house, and we were trying to manage them so they didn't trip over each other. I asked Enviro Works when we could finish the job, and he said that all his technicians were busy for the near future, and scheduled the completion for June 4th, almost a full week later and we're wondering if it would have been scheduled if we didn't insist it get done soon. This aspect could have been remedied with clear communication when we set up the initial appointment, explaining that the decommission would have to be a two-step process. It all could have been disastrous in the period before they came to finish the job. Roofers were on the site replacing our roof. Since they had to work around this gaping hole right next to the house, they took down the orange fence. When they were done, they just left the flimsy plywood. We were hanging out in the front yard considering all the work, when my toddler ran over to the plywood and stood on it. Luckily, it didn't collapse. Luckily, my son didn't fall into a ~6 foot cavern filled with toxic oil product. This was terrifying, and I was just really upset with the whole process. You could say that this was not solely Environmental Works' fault: that the roofers didn't put the plasticky fence back up. Regardless, I was upset with the whole cascade of events.
