ADEM: removing diesel from soil, groundwater “time consuming endeavor”

A FOX10 News investigation continues into what the state calls a “petroleum release” at  Mobile’s public bus system’s fueling site.

The Alabama Department of Environmental Management required The WAVE Transit System to investigate the source of the leak, fix the problem and clean it up. Tuesday, April 1, FOX10 News obtained the results of a preliminary investigation, conducted by an engineering company on behalf of the WAVE.

The report reveals wetlands behind the facility , Montlimar Creek and a canal behind the facility’s parking lot were all contaminated with an unknown amount of diesel fuel.

Tuesday, we told you ADEM said the petroleum leaked from a  broken oil/water separator and a underground pipe. According to the report, that equipment was fixed January 20th.

However, pictures, taken by ADEM Friday, show an oil sheen back in the creek and canal behind the facility.

We asked ADEM spokesperson Scott Hughes if the problem is fixed, why is the sheen showing up again?

Hughes response: “As we have noted and confirmed, petroleum products were released at this site and those petroleum products have impacted the soil and groundwater at this property. While fixing a pipe that is leaking is a fairly quick and easy process, removing these petroleum products from the soil and groundwater at the site is a complex and time consuming endeavor.”

Hughes added: “It is important to note that our geologists and scientists deal with these types of petroleum releases on a daily basis. We have overseen the cleanup of petroleum products from over 10,000 different underground storage tank locations across Alabama. This is not something new to us and our staff has a proven track record of ensuring the cleanup of these types of releases.”

The preliminary investigation recommended a second investigation to determine the extent of the contamination. We asked were the investigation stands now.

ADEM’s Spokesperson responded: “On March 17 the Department received the results of the soil/groundwater investigation that was conducted at the WAVE Transit facility. This investigation included the installation of six (6) groundwater monitoring wells to collect groundwater samples and numerous soil borings around the property to collect soil samples. In addition, a recovery trench has been installed to allow for the recovery of petroleum products (diesel fuel) that were released and are now in the soil/groundwater that is underneath the property. The results of this soil/groundwater investigation are currently being reviewed by one of our geologists.”

The WAVE Transit System refers FOX10 News will continue to track the latest developments  on this case.

adem went on to say this type of leak is nothing new to the agency and it has a proven track record of ensuring clean up.

a second investigation is underway to determine the how widespread the contamination is…we will continue to track the latest developments here and on fox10tv.com
