Groundwater radon levels of 83 Bq/L (2240 PC&) generated indoor radon levels >3300 Bq/m3 (89 pCi/L) at a commercial fish hatchery. Passive and active mitigation strategies to reduce the waterborne radon levels included a packed column, a waterfall through perforated grates, surface aeration, and bottom bubblers. Though waterborne co~centrations were reduced(More)

Abstracting the underlying graph yields a simpler problem whose solution can be used, by refinement, as a guide to a solution to the original problem. A fruitful way to view domain independent planning problems is(More)
