How Science Works and How the Press Thinks Science Works.
EPA’s recent report on hydraulic fracturing is an example of how science works and how the press focuses on other aspects that mislead the public.
Research Summary: Organic Contaminants in Portland Cement
USEPA uses glycol is an indicator of hydraulic fracturing chemical migration. Recent research has shown that glycol is present in portland cement and that it leaches from the cement at concentrations in the thousands of parts per billion. Therefore glycol alone shouldn’t be used to demonstrate hydraulic fracturing contamination in aquifers.
