Thanks for the replies.

Morning Everyone,

I have periodontal disease and want to find a good periodontist in Bangkok.   Can anyone recommend the best place?

I was thinking of trying Bumrungrad?

Many thanks.

Have you considered using projector quality paint? 

 

Errr... No.

Morning Everyone,

I had a local company fit a 130" white screen (No doubt some Chinese brand...) but I'm not happy with it.  I'm using a high-end Epson projector and want to replace the current screen with something better. 

My friend in the USA recommends Elite Screens - but I can't find them here.  I've contacted many retailers, but none will post this thing to Thailand.

There must be members on here with high-end setups?  If so, just wondering where you got your projector screen from?

TIA.

The most concerning parts are the microbiological test results, especially the high number of total coliform bacteria. Coliform bacteria will not likely cause illness. However, their presence in drinking water indicates that disease-causing organisms, pathogens, could be in the water system. Since coliform bacteria usually persist in water longer than most disease-causing organisms, the absence of coliform bacteria leads to the assumption that the water supply is microbiologically safe to drink.

 

From the microbiological point of view the recommendation for sampling: "Buying drinking water bottles, then emptying them out and immediately refilling with water to be tested in their lab" is questionable. Basically for microbiological sampling always sterile containers should be used.

 

I'm going to send my filtered water to them again to have it tested to see how it is after the filter process.   I've been looking for sterile containers online, but can't find any larger enough to send them 3L.

Any idea how I could sterilize water bottles myself and not leave any contamination?   Wash them out with pure alcohol and leave in the sun for it to evaporate?

Yes I was able to finally contact them via LINE too... just this morning actually.

They wanted my home address so they could send me a quotation.

Unbelievable how backward thinking some organisations are.

And as soon as a falung was detected on the phone the line went dead so telephone contact and email contact is ignored.

 

Can you please advise how much your test cost?

And did you send the samples to them or did they collect them?

I think it was around 6000 baht.  I took the samples myself and sent them express courier.  They wanted 3L of water.

Agreed.

This is being one of the reasons why I question the validity of the Coliform bacteria count results on the test.

I'm going to test it again.  I've ordered three inline uv filters for the system to kill bacteria/viruses.  One will filter it before it goes in to the "clean water" tank and then two as it goes out to the house.  Just to be sure.

May I ask how you contacted TestTech and how you specified what you wanted in the test criteria?

 

The test report you have shows a lot more testing than those explained on their website, and I am interested in finding out how your test criteria was determined.

 

The reason why I ask is that I have tried to contact them myself (in English) via the email address on the Contact Us page on their website, but no answer.

 

My wife has also tried to contact them (in Thai) via the message facility on the Contact Us page on their website, but no answer.

Sorry for the late reply, I've been travelling.  They didn't respond to my emails.  The only way I could contact them was via LINE app.  This was their standard test, I didn't ask for any specific testing.

  Rainwater contains a lot of airborne and surface contaminates. Your 2-stage filter process might be okay for washing and cleaning, but I myself wouldn't drink it.

   I filter our well-water using a 3-stage system for our home and a separate 5-stage system for the drinking water. 

   Here's an article I read a couple of days ago.

Could you post some details of your filter systems?

Can you substantiate your claim?

In the UK we used Berkey filters for the tap water there to remove fluoride...

I think the better and cheaper option would be to install filters consisting of manganese dioxide, carbon and resin - no aeration tanks necessary.

UV won't hurt but I don't see much of a benefit, considering the cost if you intend on installing RO for drinking.

I would not pay that much of attention to the elevated bacterial count:

I don't particularly trust that metric on their report.

If your well bore is properly sealed from the surface water ingress then it shouldn't have any problem with bacteria at those depths.

 

Thanks again for the reply.  For Aeration, I was just going to install a compressor pump in the deep well reservoir tank to pump a load of air bubbles for it, it's not hard to do this, so can't hurt?  I'll also add an oxidation tray on the top from the deep well feed, they're easy to make from pipe.  ????   So plenty of oxygen in the water.

Regarding the bacterial count.

Wonder what containers were used to send the water samples to the lab?

The lab suggests buying drinking water bottles, then emptying them out and immediately refilling with water to be tested in their lab.

All done in order to prevent bacterial cross-contamination.

Thanks for taking the time to reply.   I used brand-new water bottles from 7/11 and emptied them out.

This is my plan for filtering...

For filtering, I'm going to look at building an aeration tank to oxidise the manganese/iron pre filter, then filters/water softeners for the iron/manganese/calcium carbonate, and finally a UV system to kill the bacteria.

For drinking an R/O system on the main kitchen tap.

Please also note, I make a mistake, the deep well is 190m

How about the arsenic content?  That has me worried...

I read online that the EPA sets a limit of 0.01 mg/l.   The reading from my well is 0.0069 milligram/mL.  

This seems to be well under the limit?  Or have I got my calculations wrong?

290M deep wow, ours is only 40ish

 

Edit: You should have gone with rain water storage

 

200k approx for this and stores around 50k Litres 

 

 

Edit: Only used for Dishes / Showers / Washing and NOT for drinking

Very cool, but I didn't want to take up so much space.  I have 4 x 5000L tanks for storing rain water.

The arsenic figure is high, as is the fluoride.

One cannot filter fluoride out, it would need an ion exchange column to do so.

I would not cook with it or drink it. Showering in it or washing dishes would be risky unless first sterilized.

The calcium hardness means one can expect a fair amount of scaling in pipes.

Thanks for the feedback. 

I didn't think the arsenic is high at 0.0069mg/L when it says maximum allowable 0.05mg/L ?  I guess I'll need to research this more...

I thought you could use PFA-2 filters for fluoride?

Anyway, no problem, we certainly won't drink it.   How about if we want to use it for showering/washing dishes?  How could we treat the water to make it OK for this?

I'll try and find out if there is a lab that could test trivalent and hexavalent chromium content.

One other thing about our well is the water coming out is hot.  The deep well company said they have never seen this before on Samui.

Hi There,

I would test it again after filtering to see how it is.  I guess that then brings the question, how often would you need to keep testing it due to possible changes?

It was around 400,000 baht for that well.  It was our only option as I wanted my own water source (not going to pay water trucks here) plus it's for a large 5-bedroom villa.  I also have storage tanks to collect our well water.

Maybe I'll just go with an R/O system for drinking.  (I'll test that as well!)

Thanks.
 

Evening Everyone,

I just got the results back from a test of my deep well water.  (290m deep well) To me, it all looks good - but I'm no expert.  I was wondering if anyone on here drinks their well water?

I'm going to install filters to filter iron/manganese/fluoride and a UV system to kill all bacteria.

I'm just wondering if you would drink it?   My other thought is to install an R/O system purely for our drinking water.

I really hate using plastic bottles here in Thailand and would much prefer to drink my own water.

Thanks in advance!

Thanks Guys.  I'm going to use them asap.

We've just had a 200m+ deep well dug and would like to test the water for contaminants like nitrates/voc's, etc.

Can anyone recommend a company that does a full analysis?
