"A politically driven theory" (Daily Camera Open Forum, Jan. 23) wants scientific evidence that "fracking is a major polluter." This request is surprising because scientific publications on fracking pollution are widespread and easily available. For an introduction to fracking's effects in the Front Range, I recommend Boulder County Commissioners' Resolution 2013-55 (available online). This summarizes the relevant science on toxic gases, dust and smoke from fracking, and on their ill effects on Front Range residents. For detailed, peer-reviewed scientific papers on fracking pollution, see, for example, http://dx.doi.org/10.1289/ehp.1307866, http://doi.10.1021/es404621d and doi: 10.1021./es4053472). These and other studies report that fracking releases hundreds of toxic gases, including volumes of the carcinogen benzene, into our air.

The letter also asserts that concerns about fracking are "politically driven." No, they are driven by a desire for a healthy, attractive environment and a good quality of life. These sometimes require political engagement (such as urging Rep. Jared Polis, 202- 225-2161, 303-484-9596, or polis.house.gov, to oppose the TPP, which could prevent regulation of fracking). Opposition to fracking, however, comes from many political directions, witness "Fracking: A battle of rights" (Open Forum, Feb. 4), by a writer with "strong libertarian leanings."
