A �Frack Film Festival� slated for Saturday in Wichita will explore the effects of horizontal fracturing in Kansas.



The festival, slated from 11 a.m. to 7 p.m. Saturday, is at the Peace and Social Justice Center, 1407 N. Topeka, Wichita.



Kansas Climate Action, a group whose Facebook site posts are against hydraulic fracturing, is putting on the event.



Hydraulic fracturing � or fracking � begins by drilling vertically down to the desired geologic zone, and then horizontally through the rock layer.



Producers then pump hundreds of thousands, sometimes up to a few million gallons, of chemically treated water and sand into the well at high pressure to fracture the underlying rock layer and release the oil and gas trapped there.



While the concept has spurred an economic boom the past few years in south-central Kansas and Oklahoma, it has also raised concerns from environmentalists that the process is causing earthquakes felt across Kansas, as well as groundwater contamination.



According to a press release, the film series is aimed at educating people about �fracking� so they can talk to lawmakers during the upcoming session.



Film schedule:



11 a.m. to 12:45 p.m � "Gasland"1:15 to 3:15 p.m � "Gasland II"3:45 to 5 p.m � "Groundswell Rising"5:30 to 6:30 p.m. � "Oklahoma Shakedown"



A 30-minute slot is designated after each film for discussion. Experts on the issue are invited to come. Dakota Raynes, who appeared in "Oklahoma Shakedown," will be present for the final film and discussion. A free-will offering is requested for the Peace Center but is not necessary to see the films.



Refreshments will be provided, but organizers said participants can also bring snacks to share.
