| 摘要： | When the New Orleans Engineer District updated its salt water wedge tracker October 9, the leading edge-or toe-of the wedge intruding from the Gulf of Mexico had retreated back downriver an estimated 5.5 miles from its previous location near Mile 69.4 above Head of Passes (AHP). The Corps last surveyed the wedge October 5 and found the toe at Mile 65.3 AHP, and as of October 9, the district now estimates the toe to be at about Mile 63.9. The positive development follows an October 5 press conference where the New Orleans District announced an update to its projections for when the wedge could reach municipal water intakes in upper Plaquemines, St. Bernard, Orleans and Jefferson parishes. As of that October 5 update, the Corps said chloride levels at the region's largest water intakes in Orleans and Jefferson par- ishes would likely not exceed 250 parts per million after all. Lower Plaquemines Parish has been dealing with elevated chloride in the river since June. |
