Excerpt: Engineers who removed certain data from spreadsheets used for groundwater monitoring at the time of the 2008 Kingston coal fly ash spill did so because they thought it would confuse the results for others, including upper-level TVA management, a TVA engineer testified Monday as the second week of trial in the fly ash lawsuit began.
About 230 plaintiffs are suing TVA, claiming damage to property and health when a holding cell and dike collapsed in the early morning hours of Dec. 22, 2008, spilling 5.4 million cubic yards of coal fly ash into the Emory River and surrounding property.
Under questioning by plaintiffs lawyer David Byrne, Jamey Dotson said he and other TVA engineers left out data collected from de-watering well points because they believed it might confuse data from piezometers.
