DEQ to conduct dye study on Bayou Lafourche from Donaldsonville to Thibodaux

Tuesday, March 19, 2013 - 6:00am

The Louisiana Department of Environmental Quality will be performing a series of dye studies on Bayou Lafourche in Ascension, Assumption, and Lafourche Parishes. The studies will begin the week of March 18 and will include a series of dye injections in the weeks following, while conditions allow.

During each study, bright red, non-toxic dye will be injected into the water. Citizens who notice the red coloration of the water should not be alarmed. The water body will return to its normal state and color by the end of the day. The survey is being conducted to gather information on flow patterns in the bayou with the influence of the varying pump stations. The data collected will help establish better procedures to maintain the water quality during natural disasters, such as flooding during hurricanes.
