This is a question I received on youtube. I wanted to address this question in front of the group so we can get some feed back.

Hi Keven my name is Shane i'm from Ireland, i just want to ask you a question or two.

There is an outbreak of cryptosporidium in Ireland and in the area in which i live has just been infected with it.

Will it be still safe to drink the tap water after boiling it because I have been told it has no effect on the cryptosporidium? I'm spending a fortune on bottled water at the moment.

And also is it safe to have a shower or a bath with this water or will you get infected?

Could you please write back if you have time to spare.

Thank you

Shane.
Shane - instead of telling you this or that from my opinion, I would like to quote some other websites on this matter.

http://en.wikipedia.org/wiki/Cryptosporidium
Cryptosporidium has a spore phase (oocyst) and in this state can survive for lengthy periods outside a host and also can resist many common disinfectants, notably chlorine based disinfectants.[3]

Because of this resistance, water purification to eliminate Cryptosporidium generally relies upon coagulation followed by filtration or boiling.

http://www.cdc.gov/NCIDOD/DPD/parasites/cryptosporidiosis/factsht_cryptosporidiosis.htm
Do not rely on chemicals to disinfect water and kill Cryptosporidium. Because it has a thick outer shell, this particular parasite is highly resistant to disinfectants such as chlorine and iodine.

http://www.cdc.gov/NCIDOD/DPD/parasites/cryptosporidiosis/factsht_crypto_prevent_water.htm
Filtering tap water: Many, but not all available home water filters remove Cryptosporidium. Some filter designs are more suitable for removal of Cryptosporidium than others. Filters that have the words "reverse osmosis" on the label protect against Cryptosporidium. Many other types of filters that work by micro-straining also work. Look for a filter that has a pore size of 1 micron or less. This will remove microbes 1 micron or greater in diameter (Cryptosporidium, Giardia). There are two types of these — "absolute 1 micron" filters and "nominal 1 micron" filters. The absolute 1 micron filter will more consistently remove Cryptosporidium than a nominal filter. Some nominal 1 micron filters will allow 20% to 30% of 1 micron particles to pass through.
If I were in your situation, I would go to the local store that sells tap water filters, look for one that says "reverse osmosis" on it. Get the model number, use your cell phone to call one of your buddies, get them to go to the website of that product, look up what it protects against. If the website of that product says it protects against Cryptosporidium, buy it, go home and put it on your water faucet. Also look at the micro size of the filter.

There are some ultra-violet pen lights that are supposed to kill any organisms in water. So that might be another item to look at.

Some hand held filters for hikers and campers are supposed to protect against Cryptosporidium as well.

Wow !
I am surprised this is in a city utility.
I use a Britta filter for my drinking water, but I never thought about a contamination, such as this, being in the public works.
I would be cautious about bathing in it for sure.
We all have orifaces that something like this could "Swim" into.
I agree with Kev !
Get a good filtration system, but I would also concider some sort of house type unit.
Does water "Softening" systems help in this area?
I need to do some research I think.
Thanks for the posting.

I wonder how many of us are ready for our water supply to be shut off? This is a very real condition, in a modern city with modern water quality control standards. This has made me look very seriously into a good water filter for at least one of my sinks.

Cryptosporidium outbreak discovered in Clonmel water supply

Saturday, August 04, 2007
Clonmel residents have been urged not to panic following the revelation that a strain of the cryptosporidium parasite was found in the water supply of the County Tipperary town.

The revelation was made during an emergency meeting of the town council last night.

A 'boil water' notice has been issued this morning to houses in the area as a precautionary measure. The warning is expected to remain in place over the coming weeks.

It's understood that the parasite is a different strain to that which has caused major problems for thousand of residents in Galway over the last months.

This article gore all the way back to September 2000

http://news.bbc.co.uk/2/hi/uk_news/northern_ireland/907683.stm
The head of the water service in Northern Ireland has defended his department's handling of the cryptosporidium outbreak on the outskirts of Belfast.

About 100,000 people have been advised to boil their water in the Dunmurry, Poleglass and Lisburn areas as a precaution against the bug.

The Poleglass reservoir which supplies the areas is now being flushed out.

Speaking on Saturday, the chief executive of the Water Service, Robert Martin, said they set up their outbreak control team quickly enough.
