There have also been studies that suggest that chemicals used during fracking, such as methanol, formaldehyde, sodium hydroxide etc., are carcinogens 2. When fracking occurs in a specific site, the chance for contamination is low but as the number of sites increase, the chance for contamination increases 4. It is suggested that advanced testing should be used to trace chemicals used in water during fracking to groundwater and determine if there is a correlation 4. It is projected that many shale productions around the country will have an increase in water usage and it is very important to determine if this will be harmful to public health
