Replication Data For: Hydraulic Fracturing Chemicals Reporting: Analysis of Available Data and Recommendations for Policymakers

The Level 0 (L0) through Level 4 (L4) data sets provided here track our process to eventually obtain a clean and standardized version of original data submitted to the FracFocus Chemical Disclosure Registry (http://fracfocus.org/data­download) by oil and gas well operators. Researchers at Harvard Law School and Harvard University, Earth & Planetary Sciences Department (Harvard) used these L0 through L4 data sets to conduct data quality and chemical disclosure analyses. The datasets provided here for public use will enable others to replicate our analysis.

本文提供的0级（L0）至4级（L4）数据集，完整追踪了我们从油气井运营商提交至压裂液化学品披露注册表（FracFocus Chemical Disclosure Registry，http://fracfocus.org/data-download）的原始数据中，最终获取洁净标准化版本的全流程。哈佛大学法学院与哈佛大学地球与行星科学系（下称哈佛）的研究人员依托上述数据集开展了数据质量评估与化学品披露情况分析。本次公开提供的数据集可支持其他研究者复现本团队的分析工作。
