A study that examined waterways in Accomack County has revealed the rapid expansion of poultry operations in the county has had no detectable effects on local water quality.
The research was conducted in response to concerns that the proximity of commercial poultry houses and the increased use of poultry litter as fertilizer would contaminate Eastern Shore waterways.
However, after examining data from 86 streams in Accomack, the Virginia Institute of Marine Science determined there was no correlation between water nutrient levels and the presence of poultry operations.
“The goal of the study was to find out if there was any measurable impact from these poultry operations,” said VIMS director Richard Snyder, who helped conduct the research. “The basic conclusion of the report is that there is no significant difference between watersheds that have poultry operations and those that do not.”
The study monitored dissolved ammonia, liquefied nitrates and nitrites, dissolved oxygen, total phosphorus and nitrogen levels, temperature, salinity and turbidity in Accomack County streams. Values were collected during two 1-inch rainfall events and over an extended period of drought in 2020.
