SciCheck spills the scientific T on water quality data – and schools Rep. Steve King on his recent claims (including the snarky, but hilarious point that ‘bison’ is more scientifically accurate than ‘buffalo’).

During a recent congressional hearing, Rep. Steve King of Iowa underestimated what scientists know about the relationship between farming practices and water quality.

  • King said scientists don’t know about the quality of water in the U.S. “when the buffalo roamed” because there were “no water quality tests then.” Pre-1900 water quality data is relatively scarce, but experts can use techniques from paleolimnology to evaluate past water quality.
  • He implied that this lack of “baseline” data prevents scientists from knowing whether applications of crop fertilizer are “too much.” But experts say they don’t need 19th century data to know fertilizers have negatively impacted water quality. The 20th century provides plenty of evidence.

To start, the term “bison” is scientifically more accurate than “buffalo” when referring to North American populations.
