While there is little evidence that hydraulic fracturing is directly linked to widespread negative health and environmental effects, the data and record-keeping necessary to understand whether the practice is contaminating future drinking water supplies and injuring nearby residents are incomplete, according to an independent scientific report released Thursday by the California Council on Science and Technology. The state Senate commissioned the study in 2013.
