Cost-effective cyanobacteria treatment is a key topic at western states water meeting

Earth Science Laboratories will discuss controlling cyanobacteria with ionic copper at joint meeting of water experts from Arizona, California and Nevada.

LAS VEGAS – Summer is cyanobacteria season, especially in the dry, arid states of the West. As potentially toxic blooms have increased in recent decades, so too has the need for effective treatment. Cost-effective cyanobacteria treatment will be a key topic when water experts from Arizona, California and Nevada meet next month.

The Tri-State Seminar convenes in Las Vegas, Aug. 6-8. This year’s event will take place at the height of summer, when cyanobacteria blooms are most frequent. Sixty such blooms have been reported in California in the past month alone. Left unchecked, these green, slimy blooms can produce toxins that are harmful to animals and humans.

Rapid and cost-effective control of cyanobacteria blooms is critical for water treatment plants. This is especially true for plants that draw water from the many artificial reservoirs in the West. These reservoirs are vulnerable to cyanobacteria because they receive high nutrient loads from large rivers such as the Colorado and its tributaries.

Ionic copper is an effective and cost-effective solution according to Dr. David Hammond, Senior Scientist at Earth Science Laboratories and a scheduled speaker at the Tri-State Seminar. “Ionic copper stays in solution rather than settling to accumulate in the sediments,” Hammond said. “This is one reason it performs at unprecedentedly low dose rates that have minimal impact on fish and other non-target organisms.”

Hammond is scheduled to present case studies and data at the Tri-State Seminar on an ionic copper algaecide called EarthTec®. The presentation entitled “Smart Water Treatment” will take place on Wednesday, Aug. 7 at 10:40 a.m. More information on the Tri-State Seminar is available at
