In 1988 the last time it happened it didn't get to Carrollton station. Currently it's expected to impact Carrollton station week 3 of October.

The plan right now is to truck in water to keep chloride levels below 200ppm.
But from what it understand the water will taste funky above 20ppm.
It'll be safe to use and drink but taste off. Which we can deal with.
I don't think we need to hoard water bottles. But I would still shut off water to my fridge.

Do you know how much water would have to be barged in per day to blend it to and aesthetic level? Algiers maybe feasible but EB of NO is a pipe dream.

The current levels of chloride are above 20 and have been that way for years. 30-50 is normal.

Just think of all the turds and piss in the river, thousand miles worth - salt would be the least of my concerns.

Thank God your plumber knows. Does he have any crypto recommendations?

The goal is to bring in 1mm gals a day to the intakes downriver, of course you would need to double or triple that at Carrolton.

Link to when the local water supply was over 200ppm chloride?



Did I say anything about the water supply being over 200ppm chloride? (The correct answer is No.)

I was just trying to point out that the salt water wedge has caused issues befote, but I don't ever remember any catastrophic problems. I know the USACE has built their sill in previous low water events, but I don't remember any severe effects.

I think I read that the "safe" salinity level for drinking water is 250ppm. I have no idea what "normal" levels are, but I suspect they're somewhere above 0ppm. I could be wrong.

1MGD wont work for Algiers water plant much less Carrolton. You would have to bring in 60 MGD at Carrolton. 4ish MGD at Algiers.

You do realize the water doesn’t go straight to your house straight from the river correct? You realize that it goes to a treatment facility first before it going to your home?


You do realize if there were a cost effective way to desalinate water the world would be a much more prosperous place?

I had my plumber at my house yesterday working on something and I asked him about the saltwater approaching New Orleans. He said the media has the story all wrong; drinking water is not going to be an issue, the real issue is exposing saltwater to the systems inside of your house. Dishwasher, fridge, washer, hot water heater, etc.

What says the OT?


I say if your plumber referred to your water heater as a HOT WATER HEATER then I would tell him to get THE frickK OUT OF MY HOUSE!!!

I said down river

Jefferson Parish sent something out a few days ago that the current Cloride level in JP was 40 milligrams per liter(mpl) and that the safe limit was 250 mpl

I bet he sold you an whole home filtration system too didnt he?

If the water coming into your house is safe enough to drink it is safe enough for your appliances.

I don't think it will get to that point.

This is going to be solved by multiple solutions, occuring simultaneously.

1) Reverse osmosis what they can

2) Dillution via mixing in barged water from upriver

3) Chemical treatment as necessary

The above will treat a good amount of water but won't treat enough water to account for normal every day use. So...

4) free bottled water distribution

5) Water restrictions (water lawns on only certain days of week, restrict car washes, etc)

I do beleive that before they allowed too-salty corrosive water to enter the system, they would shut down / major restrict the system. Of course that creates a massive fire risk.

All that is fine and dandy for private residences and retail stores but hotels and restaurants and some medical facilities will have to shut down or bring in a shitload of potable water in those Rain for Rent trailers
