Dear Drinking Water Inspectorate,

I read with interest, your report on approved chemicals that are permitted to be added to the drinking water.
I do NOT see arsenic, lead and mercury on this list. I have DEFINITIVE proof that these chemicals are added to the water as part of a toxic waste known as hexafluorosilicic acid.

I say again, these chemicals are actually ADDED to the water as the hexafluorosilicic acid (H2SI4) is not pharmaceutical grade. In other words, these chemicals are present in the drinking water after BEING ADDED in certain areas and their presence is clearly illegal.

I have FACTUAL evidence of this as I possess an information pack from Yara Industrial (the supplier) and it clearly states the presence of these chemicals and other unapproved substances in this toxic waste scrubbed from the phosphate process.

Now the ramifications of these facts are obvious. In order to comply with the Drinking Water Inspectorate, these chemicals MUST be removed from the hexafluorosilicic acid BEFORE it is added to the water. Failure to do so is a breach of the law. This would deem it necessary to produce hexafluorosilicic acid as a pharmaceutical grade product (which everyone, including most dentists and health professionals assumed incorrectly that it was anyway) which of course, would make the cost prohibitive.

So now, the rather weak evidence in support of water fluoridation is undermined YET AGAIN and even more relevantly, makes the process as it stands, illegal.

I would like to know WHY this waste is STILL being ADDED to our water when there are these dangerous UNAPPROVED chemicals being added with it?

If you require PROOF that what I say is true, I shall provide a copy of the PDF file straight from the suppliers of this toxic waste (euphemistically known as a co-product).

Yours faithfully,

Trevor Allport

Dear Mr Allport

Thank you for your email of 25 May to DWI.

You refer to the DWI report on approved chemicals that can be added to the water supply which I assume you mean the "List of Approved Products for use in Public Water Supply in the United Kingdom". You also ask why hexafluorosilicic acid is (still) permitted to be added to the water supply.

Some water companies, at the request of the local health authority, fluoridate water supplies, as described in http://dwi.defra.gov.uk/consumers/advice... Only two chemicals are permitted to be used for this purpose, hexa-fluorosilicic acid or sodium hexafluorosilcate. However these chemicals must conform to the specifications, including quality, of BS:EN 12175:2006 "chemicals used for treatment of water intended for human consumption" (in respect of hexa-fluorosilicic acid) or BS:EN 12174:2006 (in respect of sodium hexafluorosilicate). It is the responsibility of the water company to ensure that it uses the appropriate grade of treatment chemical.

As you acknowledge in your correspondence, with the Company and ourselves, Anglian Water use hexafluorosilicic acid to fluoridate some supplies in their area. They purchase this chemical from Yara and verify that it is compliant with the appropriate BS:EN. The chemical is therefore being used legally by Anglian Water.

Dear DWI Enquiries (DWI),

Thank you for your reply.

I am NOT referring to your consumer advice document on fluoridation of water. I am referring to your 'List of Approved Products for Use in Public Water Supply in the United Kingdom'. I enclose a link to said document.

http://dwi.defra.gov.uk/drinking-water-p...

Now the H2SIF6 may comply with BS:EN 12175:2006 but it certainly does not comply with the list of your approved products.

In manufacture of a chemical, every attempt must be made to eliminate hazardous impurities at time of manufacture.

As this is a WASTE product and cost prohibitive to do so, this elimination stage of the process is not performed.

So basically, the chemicals arsenic, lead and mercury are being DELIBERATELY added to the water.

If the hexafluorosilicic acid was a SPECIFICALLY MANUFACTURED CHEMICAL of pharmaceutical grade, this would not be the case. So a WASTE PRODUCT with known hazardous impurities is being dumped into our water.

So, to summarise.

1)The hazardous chemicals consisting of (but certainly not limited to) arsenic, lead and mercury are NOT on your approved list and yet are added.
This basically nullifies any information presented in your approved list. Any of the chemicals listed could have upteen impurities with your blessing which inevitably leads to shoddy chemical manufacture ( or even use of hazardous waste as a chemical to add).

2)It would be possible to ELIMINATE these dangerous impurities by modifying the production process of the chemical by manufacturing it pharmaceutically rather than extracting it as waste from another process.
I realise that the levels of these impurities are within limits but the arsenic limit, specifically, is taken from data prior to research showing it's links with cancer. We cannot justify ADDING these chemicals deliberately.

3)Dental and health professionals already ASSUME that the hexafluorosilicic acid is of pharmaceutical grade and not industrial waste and are therefore unaware of the existence of these impurities.

As a doctor, I hope you can help me understand the EXTREMELY powerful politics that is NOT backed up by equally powerful science as to why, in the 21st century, we are still adding this toxic nonsense to our water supply.

Yours sincerely,

Trevor Allport

Dear Mr Allport

Thank you for your reply to Dr White's email.

As Dr White explained when a treatment chemical conforms to a specification in a BS:EN, such as in this case BS:EN 12175:2006 for hexafluorosilicic acid, the treatment chemical is permitted to be used legally in water supplies in the UK (and in other European member states since BS:ENs are European Standards). The specification in the BS:EN places limits on, and therefore controls the levels, of impurities including the ones you refer to, that are permitted in the chemical.

Dear Drinking Water Inspectorate,

Please pass this on to the person who conducts Freedom of Information reviews.

I am writing to request an internal review of Drinking Water Inspectorate's handling of my FOI request 'Evidence of Unapproved Chemicals added to Drinking Water'.

The reply does NOT explain the omission of these chemicals in the list of aaproved chemicals added to water.
These chemicals are scientifically avoidable and as such, should not be added.
Also, if they are permissable, even at very low levels, they should be included on the list of approved chemicals added to drinking water.

A full history of my FOI request and all correspondence is available on the Internet at this address:

Dear Mr All port

Thank you for your request for an internal review by Defra of the DWI handling of your request “Evidence of unapproved chemicals added to drinking water” received on 16 June 2011.

The Defra Information Rights Team cannot carry out an internal review on the FOI handling of this request because it was dealt with as a routine enquiry, not as an FOI request.

Under European law, any treatment chemical with a European standard is permitted for use in drinking water in all member states. Control of level of impurities in a treatment chemical is determined by the body responsible for the standard, in the UK, this is the British Standards Institute (BSI). You are advised to put your questions to BSI. The contact details are: BSI, 389 Chiswick High Road, London W4 4AL, Tel: 020 8996 9001.

We will not be corresponding further with you on this matter.

It appears that the issue raised here is being side stepped, with a side salad of buck passing. I'd encourage people to engage their own GP's in such correspondance, they too are drinking the same water. It will be more difficult for them to ignore GP's.

BS EN 12175:2006 says this - "This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations."

And this - "In respect of potential adverse effects on the quality of water intended for human consumption, caused by the product covered by this document: a) this document provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA ;"

And this - "NOTE Users of this product should check the national regulations in order to clarify whether it is of appropriate purity for treatment of water intended for human consumption, taking into account raw water quality, required dosage, contents of other impurities and additives used in the products not stated in this document."

So - can anyone please tell me how is BS EN 12175:2006 to be relied upon as the sole legal regulation of fluoridation chemicals? Where is the law that says only this BSI must be used and is sufficient? It is not at all clear to me.
