Environmental engineers with the state and the city of Little Rock are still looking into the illegal dumping of restaurant grease that we first told you about last week.

The city's public works department has requested that a camera be put down into the pipes connected to a storm drain at the library.

That's all in an effort to see just how that grease is gumming up the works.

Last week's library surveillance video showed someone dumping where they shouldn't have been.

The tape also shows a woman walking nearby who fell on the slick substance left behind.

Value Stream is one company in the area that's committed to handling brown grease collected from clients in the right way.

On average, crews there haul away about 30 thousand gallons of it per week.

It gets stored in these tanks at a disposal site in Woodson, until that organic material can be re-used by being injected into the earth as a soil conditioner.

It's a natural fertilizer and Value Stream plows it back into the earth to reclaim land that's been farmed out.

It's also used an activator in compost.

As of yet, no one's claimed the reward the library's offering for information about last week's incident.
