Dye Tests Performed in Humboldt Bay
A water quality study being performed by the California Department of Public Health uses red dye. According to an earlier press release from Humboldt County,
Scientists, aboard boats and on the shore, will observe the colored water with instrumentation to see how the currents flow and how the dye is diluted. This will illustrate how water currents and transport of treated wastewater could be affected by proposed improvements to the Arcata Wastewater Treatment Plant, and a proposed move of the plant’s outfall. That information will help CDPH decide where commercial shellfishing can safely be allowed.
