IS IT TRUE the CCO believes the following assessment of the toxic spill headed our way by John Blair of Valley Watch is worthy of publishing for this Saturday’s version of IIT?
I had a discussion with someone this morning about the chemical spill headed our way. The worry expressed gave me reason to write this.
I told the person that I thought the stress that was being experienced was likely a greater threat to human health and the relatively low concentrations of the chemical that will be seen in Evansville by the time it gets here and assuming that Wendy’s discussion with Alan Mounts at the Water utility was valid and that the leak has been stopped and is not on going. Frankly, I was concerned with the seeming dismissive attitude of Wendy’s questions by Mr. Mounts
It is also true that activated carbon is a great way to remove hydrocarbons from water, although I am left to wonder what happens to the waste activated carbon that is now tainted with the chemicals it has removed. But if Mounts is right and the concentration of the chemical is below 35 PPB, I see little reason for stressful worry and the best thing to do is to simply not drink local water or take long showers or baths until the slug has passed.
I have more to say but do not have time right now to write a broader thesis on this subject. However, we would all realize that we are routinely exposed to a wide array of toxic substances every day. Each year, the polluters around us emit upwards of 58 million pound of toxic air pollution, some of which reaches us EVERY DAY regardless of the direction of the wind. Once while on the river I discovered about a dozen empty herbicide containers afloat.
When I first started dealing with these issues, there had been a study done that revealed that 450 different chemicals had been identified in Ohio River water. Around that time, too, we had a huge carbon tetrachloride spill from the FMC Corp way up river and a couple of nasty hydrocarbon chemicals call hexa and octa that were not only a threat to our water but closed down Louisville’s Morris Foreman Treatment plant for nearly a year forcing Louisville to dump more than 100 million gallons each and every day for more than a year.
As a result of those problems ORSANCO developed a great “early warning system” to track this sort of problem and I am confident it will be used effectively in the days to come as this slug of nastiness moves down river.
Last, our drinking water source is the Ohio River. When Valley Watch first formed there was little but non sport fish in it. Today, there are many more species that seem to be thriving. We are making progress due to regulations and technology. We are fortunate here to have a system of activated carbon treatment that can remove most of these nasty hydrocarbons and I reiterate: stress about this is likely to cause you and your loved ones more health issues than a rather limited concentration of a toxic chemical passing us by, especially with good treatment.
