It is with heavy hearts that we announce the passing of our dear friend and Vice President, Veronica McNew. After a long, hard fight against cancer, she was called home on December 3, 2021. Veronica faithfully served EE USA for 25 years. She began her career at EE USA in the Effluents Testing Lab. Through her hard work, she quickly became Effluents Testing Lab Supervisor, then Marketing Manager and most recently, Vice President. Veronica was a self-starter with her father’s work ethic. When her responsibilities within EE USA changed, you could still find her assisting in the lab. She was always ready to lend a helping hand, even when her fight against cancer was very debilitating. Veronica is survived by her husband Trigg, mother, brother, and a host of family members. She will be greatly missed by the EE USA family. We ask that you pray for her husband, mother and family in the days and weeks ahead.
Common Names for these tests: Freshwater Toxicity or Water Toxicity
Freshwater Testing Methods
Whole Effluent Toxicity (WET) tests were developed as a tool to evaluate the potential harmful effects of effluent discharged into surface water. Carefully chosen indicator organisms are exposed to whole effluent and/or effluent dilutions for a specified period of time to observe the effluent's effect on the organisms and its potential to effect organisms in the receiving stream. Test methods and duration of the tests are specified in the discharger's permit.
Whether you are a waste water treatment plant, chemical plant, refinery, or product manufacturer, contact us to discuss your permit or research needs.
