Actually, they set a limit for drinking water. The limit is 4.0 parts per trillion. That is also the instrument detection limit, meaning essentially zero. Drinking water facilities do not add PFAS chemicals to the water. But they are responsible for removing it. At an extremely large cost. The cost will of course be passed onto the consumer. PFAS are suspected carcinogens, but nothing more definitive. In my opinion, the greatest health effect is a correlation to PFAS concentration and reduced in birth weight. PFAS manufacturing is no longer occurring in the US. It's uses are now extremely limited, except in small concentrations where no other chemical can be substituted. As a result, the EPA has reduced PFOS from 30 ng/L in the average citizen's bloodstream to about 5 ng/L since 2000. So it is in decline. PFAS is still being manufactured in China, as can be imagined. Most of the products containing PFAS, which are many, are also still being manufactured there. There is no easy solution to eliminating every last trace of PFAS chemicals, since it is everywhere. Even the removal is a problem, as the EPA has realized the issue with disposing of the spent carbon resins. While I don't want any of these chemicals in my body (it takes about 4 years to eliminate half the concentration of PFAS in ones body) I'm not so sure of the EPA's recent response But don't get me started on the issue.

NJ has a 0.4 ug/L limit in drinking water, while Alaska allows up to 77 ug/L. California's limit is 1.0 ug/L, while Delaware allows up to 6 ug/L. The main source is from fertilizers, but it is also in shampoos and skin products. That doesn't sound right. NY banned it, except for trace amounts, whatever that is.

Which one? Of course, legally, all chlorinated tap water contains a certain level of trihalomethanes, which are known carcinogens. I have a carbon filter on our kitchen sink just for that.

One would think there has to a "happy medium". Not sure if you can sue for not salting? Especially when the forecast is for 1/4" of dry powdery snow. Potable water is impacted from too much salt. Not just for residents, but industry as well. More potable water is used by many industries with high ionic/TDS content...

Nice try, but no. What about heat loss due to evaporative cooling over the waters?
-
It's a good theory, but show me the proof. There are many factors, including the general lack of cold(er) air. I'm probably most resistant due to someone blaming the Great Lakes on our night time temperatures, despite the high winds reducing the radiational cooling during that period. The effect of the Great Lakes on night time temperatures in NYC cannot be greater than 0.5 F degrees, if that. But since there are no calculations, it is only speculation...

California is a lot bigger, but their policy is hands off when it comes to clearing underbrush. There is no forest management there. They stopped that decades ago. Truth be told, I know nothing about fire prevention, but obviously the Fire Chief of LA didn't exude much confidence either, since she was recently demoted. Part scapegoat, I understand.

Down here in Garwood NJ, we had 10.3" of snow this winter...

although there is statistical reasoning, I find the 30 year temperature averages arbitrary. They don't base record highs or lows from it, nor do they base average seasonal snowfall on it.

Asking for some indoor humidity readings. Recently bought two mini hygrometers. It was reading 10%, then rose to 18% when I turned on a small humidifier right next to it.

Wow, and I though Hainseville was the icebox of New Jersey!

As much as I have been frustrated, snow amount-wise, I'll still take this winter.
-
So Central Union County NJ received two 29.5" snowstorms since 1996. Is it even possible that the greater NYC metro area can see a snowstorm >40", or a scenario of direct back to back storms totaling over that amount?

It seems the cold spots have been in either Siberia or Europe over the past 5 years or so. The Pacific jet didn't help during those years, just scouring out any cooler air in Canada. This year, we saw some of the cold pockets actually come up and over the poles, down into eastern Canada. I don't know if there is actually a why? Almost like a roulette wheel, a game of chance where the cold air will drop into to? Of course it will follow the path of least resistance, which some can explain better than myself...

Too far north to get hit with southeastern forming storms, to far south of the polar air source?
