Toxins in WaterBy Florian Sever
May 24, 2019
In past years, both Ketchikan and Sitka supported "dissolving-sulfite" pulp mills, which generated large amounts of toxic fly-ash from their power-generating boilers. Both of these mills burned bark, wood waste and toxic waste-water treatment sludge.
In 1991 the USEPA determined that high levels of 2,3,7,8 TCDD DIOXIN were present in the sediments of Sitka's water supply (Blue Lake).
The dioxins in Sitka's Blue Lake sediments were determined by the USEPA to be caused by airborne fly-ash from Sitka's pulp mill. Ketchikan's pulp mill did the very same thing to the Ketchikan airshed.
In the interest of public safety, shouldn't the drinking water of BOTH communities be REQUIRED to be filtered to remove these toxic, dioxin-laden sediments? See: https://semspub.epa.gov/work/HQ/188446.pdf , page 8.
I came across this link on the internet. It outlines a newer form of water collection and analysis than the USEPA used in Sitka and Ketchikan, regarding 2378TCDD [dioxin] in both city's water supply lakes. See: https://acwi.gov/monitoring/conference/98proceedings/Papers/25-DINK.html
