10:00AM- There were 4 PBG workers and a PBG supervisor working on a solution to the silt-laden water problem. They had dug a hole about 12-to-15ft long by 6ft wide by 6ft deep and had placed the filter bag in the bottom of the hole. Two PVC pipes were placed just below the top of the hole to enable surface water to be discharged into the wetland. It looks like the plan is to use the hole as a secondary filter , enabling any silt-laden water that doesn't get entrapped by the filter bag to settle to the bottom of the hole. The (hopefully) clearer surface water will get discharged into the wetland via the two pipes. They had also placed filter fabric over the inlet side of the two pipes as an additional filter. They did a trial run while I was there but didn't seem happy with the results. When I left they were still tweaking the set-up. It will be interesting to see how well this works. I'm sure DHEC doesn't want silt-laden water discharged into wetland areas.
2:40PM- Pump is "off". No other activity. Apparently the solution mentioned above didn't quite work as well as expected. A load of gravel has been dropped off at the site.
