The Acadian Group of the Sierra Club and the WaterMark Alliance sent a letter to LCG leaders with 10 recommended actions to remedy the recently discovered contamination of the Chicot Aquifer.

The Acadian Group of the Sierra Club and the WaterMark Alliance sent a letter to Lafayette Consolidated Government leaders outlining suggested actions to remedy the recently discovered contamination of the Chicot Aquifer near the Lafayette North Water Treatment Plant.

The letter was sent to Mayor-President Joel Robideaux, LUS Director Terry Huval, LUS Water and Wastewater Operations Manager Craig Gautreaux and all nine Lafayette City-Parish Council members, according to a press release issued jointly by the organizations.

The letter, dated March 22, lists 10 recommendations that the organizations want to see their local leaders pursue, including:

Evidence of contamination appearing in LUS drinking water wells was presented in January at a Y49 meeting organized by the Sierra Club.

The measured concentrations are below EPA Designated Contaminant Levels and are measured before treatment. However, contaminants reaching local water wells “present a warning to the public and our civic leaders that action is needed,” says Harold Schoeffler, chair of the Sierra Club Acadian Group, in the release.

According to the local blog Lafayette Connector Comments, which seeks to collect, archive and make available public comments on the I-49 Lafayette Connector project, a summary of the post titled “More Evidence of Chicot Aquifer Contamination: USGS Monitoring,” says:

The United States Geological Survey (USGS) established a monitoring well at the Lafayette North Water Treatment Plant in 2001. This well was drilled to a depth to sample the top of the Chicot Aquifer. The water plant and monitoring well are located near known surface contamination. Data collected from this well since 2001 demonstrate that in spite of the existence of a clay confining layer above the Chicot Aquifer, contaminants flowed down into the aquifer, which is the sole source for drinking water in Lafayette Parish. These findings are consistent with other evidence, and support the recommendation that action is urgently needed to protect the Chicot Aquifer.

Attention has been focused on the abandoned railyard in Downtown Lafayette since DOTD has revived their plan to construct I-49 over the railyard site, which is known to be contaminated with toxic substances including some of those being monitored in nearby LUS wells.

“Both property and public health require protection,” says Schoeffler in the release, adding that he hopes to see a response to these recommendations at future meetings of the council and utility board.
