It was a long haul, but worth it in the end.

AIS recently completed a big chunk of dredging work for CH2MHILL in the Spring Creek Arm of Keswick Reservoir.  Our dredge Corrin removed approximately 150,000 cubic yards of contaminated sediment from this tributary of the Sacramento River.  CH2MHILL and the US EPA have been working together to clean up acid mine drainage from the former Iron Mountain Mine.  AIS worked closely with AHTNA Government Services on this job.  They operated the mud treatment facility.  Dredging work goes on 24 hours a day and seven days a week, so it is very tiring.  Most of us plan to rest for about a year after this one.
