QUESTION ; Do Provinces surrounding North Bangkok have piped water treated with Chloramine [ Compound of "Chlorine" + "Ammonia" ] prior to entering public mains supply ?

[Our Man in the Tropics]

 

Dear Fellow Thaivisa.com Posters,

 

I would greatly appreciate yer earliest kind replies with convincingly authoritative answers to a particular question which through internet search I have not yet found decisive statement for to know "yay" or "nay" ;

 

Do the Provinces [ incl. Nonthoburi ] surrounding North of Bangkok have its piped water treated with Chloramine [ Compound of "Chlorine ( 3Cl2 )" + "Ammonia ( 8NH3 )" (  viz.  8NH3 + 3Cl2 --> N2 + 6NH4Cl ) ] prior to entering public mains supply ?

 

Apologies for any frustrations caused by recent thread basically asking same question ;

This version of thread begins with opening post having been necessarily corrected.

 

Thanking yee all in advance for yer positive constructive relevant replies anyway.

 

Regards,

 

Our Man in the Tropics

Any documentation you find from government sites like the PWA (Provincial Water Authority) or other local water companies are likely to be written in Thai. The filter/treatment method will vary by water source.

I believe our local plant (Pathum Thani Water Company) uses chlorine. Unfortunately my friend who worked there passed away some years back ????

 

For those who don't know, some information on chloramine water treatment https://www.epa.gov/dwreginfo/chloramines-drinking-water#

 

[tonray]

In Nonthaburi...the water is drinkable and safe..but we choose to get delivered bottled water because of the heavy taste and smell of chlorine...so my guess would be yes

[Lacessit]

Chloramines are not used in water treatment, they are the result of chlorine disinfection. Chlorine reacts with amines in water, such as those found in human and animal urine, bacteria and viruses, to form chloramine compounds.

If the presence of chloramines in tap water for drinking purposes bothers you, simply boil the water. Chlorine and chloramines are removed by steam distillation during boiling.

And in my research since about chlorination of public water,- I learn about chloramine.

I used "Find" function within those doc.s for terms "chloramine", & "NH4Cl" ;

This is most hopeful for concluding that chloramine is not [ yet ? ] purposely used in water supply of "these particular provincial water supply authorities" [ I still must uncover what respective provinces these doc.s refer to ].

Crossy's post -- post #3 -- through its link informs the reader that increasing numbers of public water supply authorities worldwide purposely use chloramine.

Also,- my research prior to creating this thread concludes that chloramine cannot be removed by boiling.

However,- the following portion of Lacessit's post is a gem resounding with penetrating logic [ because chloramine is a compound formed from reaction of chlorine + ammonia" ] that I add to my essential findings ;

"Chlorine reacts with amines in water, such as those found in human and animal urine, bacteria and viruses, to form chloramine compounds."

If chlorine but not chloramine is purposely within public water supply,- I believe that the chlorine is eminently removable by simply having a clean basin of the water -- with insect screen effectively completely covering its upper surface -- presented under the hot sun of Thailand for some hours whereby the chlorine evaporates.

The amount of chloramine in a water supply depends on the amount of pollution in the water prior to treatment. This is measured by the ratio between Free Available Chlorine ( FAC ) and Total Available Chlorine (TAC). Water authorities try to maintain FAC at 0.5 ppm, or mg/L if you prefer. A TAC measurement is a defacto statement of the amount of chloramine present; however, I am not aware of any standards or limits on the amount of chloramine allowed in drinking water.

Chlorinated organics can usually be detected by the human taste faculty at the part per billion level. I boil all my drinking water. I can't say I have ever detected an off-taste in the water I consume after boiling.

Both chlorine and chloramines result in a statistically higher level of bladder cancer after prolonged consumption. There is also some evidence chloramines are responsible for an increased incidence of soft tissue tumors.

Ammonium chloride ( NH4Cl ) is an inorganic compound. Chloramines are the reaction product of organic amines and chlorine. They are organic compounds. When chlorine oxidizes and hydrolyses the  protein present in bacteria, viruses and human waste into organic amines, they then combine with free residual chlorine.

There are alternatives to chlorine such as ozonation, boiling and UV disinfection. However, chlorine is the cheapest. It is ineffective in destroying larger oocysts such as giardia and cryptosporidia, only boiling does that.

Vitamin C and ascorbic acid are one and the same.

The invoice for this chemistry lesson will be sent to you by PM.

You're welcome.

There are carbon atoms in a chloramine. By definition, an amine is an organic compound with a nitrogen atom linked to a carbon alkyl or aromatic group. There are primary, secondary and tertiary amines, e.g. R-NH2, R-NH-R, R-N=R2.

Again by definition, organic chemistry is the chemistry of carbon compounds. Although simple compounds such as carbon dioxide or metal carbides are classed as inorganic.

You are helping me brush up on my second year degree level organic chemistry, where I had an excellent teacher who could communicate his love of the subject. I guess that level is now high school chemistry, with the passage of half a century.

What would otherwise scholars of chemistry be inclined to pursue prior to chemistry becoming a distinct science ?

[Lacessit]

Ammonium chloride is an inorganic compound. It is not a chloramine. Ammonia is not an amine.

I'm not sure when chemistry became a distinct science, one would have to go back to the Middle Ages. It's a very simple branch now, compared to the likes of biochemistry, molecular biology, and quantum physics. If my parents could have afforded it, I would have liked to have pursued a career in forensic pathology.

Metallic elements and alloys fall with in the realm of metallurgy. Chemical compounds of metals are in the field of inorganic chemistry, except when they are combined with organic carbon compounds, in which case they are organometallics. The electrochemistry of metals is otherwise known as corrosion science.

You've reminded me of an old joke. A chemical engineer is someone who is smarter than an engineer, but not smart enough to be a chemist.

_ _ _ my motivation for posing this enquiry ;

Thai technician working on my car has a skin condition claimed to be caused by chlorine in the water he uses to wash himself.

And in my research since about chlorination of public water,- I learn about chloramine.

https://en.wikipedia.org/wiki/Chloramines

 

http://www.wqa.org/learn-about-water/common-contaminants/chloramine

 

After reading this reference, I have to say I was not aware of the existence of these compounds or their nomenclature. I was always taught a chloramine is a compound of chlorine and an organic amine. I have never heard of of inorganic amines until now, so I guess my chemistry is out of date. The nomenclature I was taught would probably refer to monochloramine as nitrogen dihydrogen chloride.

Apparently monochloramine is used widely in the US as a supplemental disinfectant to chlorine itself. I don't know if Thailand has followed suit.

The water supply in Australia is derived mostly from rainfall, with a small percentage of bore water. In America, most water supply is groundwater. I understand 95% of mains drinking water to major US cities is actually recycled waste water after what is euphemistically described as tertiary treatment, so perhaps that is why I only ever drank bottled water any time I was there.

Presumably the water authorities in America feel extra disinfection is necessary, after all the water is recycled Number 1 and Number 2. Personally, I would be wary of such compounds as carcinogens, due to their potential to react further to nitrosamines, which are really bad actors.

Allergy is an immune response. As all our immune systems are different, we react differently.

There is also the issue of enhanced immune response, as the body reacts to repeated exposure with increased vehemence.

I once knew a health inspector who, as part of his job had to go into fish markets. His allergy got to the stage he only needed to stand at the door of a shed processing prawns, and his face would blow up like a pumpkin. Only a few molecules required to set him off.

I'd suggest the guy in the OP's post has probably developed an allergy to a chemical in the water, and it will only get worse with more exposure. Under those circumstances, the only viable solution is to find another occupation.

[Our Man in the Tropics]

Yet again,- all great replies ;

Thank yee.

 

I am currently far from that technician's location ;

It will be some weeks before I may be able to re-visit ;

Whence I will diligently elegantly relay what I have learnt here to him.

 

YES,- THE MAN'S IMMUNE SYSTEM HAS REACTED AGAINST SOME SUBSTANCE

I GUESS THAT WE CAN JUSTIFIABLY REFER TO HIS REACTION AS AN ALLERGY

And,- the allergic reaction could get worse.

 

I wonder myself if his skin condition is separately, or also, caused by a different factor ;

e.g.

engine coolants other than water

 

Still,- his boss did say in our presence that Chlorine is the culprit though ;

So,- I presume that medic have studied his personal condition & decided it is caused by Chlorine ;

But,- to what extent did they study his personal condition ?

 

Returning to other hazardous liquids that may, or may not, be staining too ;

 

QUESTION ;

What good + cheap Barrier Cream would yee recommend ?

 

And, not forgetting that a Barrier Cream may cause allergic reaction too.

 

And,- latex inspection glooves can.

And,- the internally-powdered version of latex inspection glooves can.

A possible reaction is hand becoming greasy, & with subsequent use of the offending glooves they become like a jelly.

Heart attack a final possibility I gather.

 

I suspect that condoms can cause similar allergies with some users.
