Tepco has fixed the problem and is cleaning the water, but is still investigating what caused the leak

The earthquake that rocked Japan this past March was an event that would have lasting effects, and Japan's nuclear watchdog is still working to clean up the mess almost four months later. Just this morning, tons of radioactive water was found absorbing into the ground from Fukushima Daiichi's nuclear power plant. 

On March 11, 2011, a 9.0-magnitude earthquake struck Japan causing tsunamis and problems for the Fukushima Daiichi nuclear power plant. Such problems include contaminated food, a nuclear meltdown, and radioactive water

Now, the Nuclear and Industrial Safety Agency has reported that 15 metric tons of radioactive water has leaked from a storage tank at Fukushima Daiichi on the Pacific Coast. The level of radiation in the water is low. 

Large amounts of water have accumulated in the storage tanks because it was used to cool the damaged reactors after the cooling systems were destroyed. The leak was discovered Monday, and the system was shut down an hour and a half after it started. 

Tokyo Electric Power Co. (Tepco) has fixed the problem and restarted the system, but is still investigating the cause of the leak. Tepco is also using a decontamination system to clean the water so it can be recycled and continue cooling the reactors.

I was about to say.

Depending on the water temperature, 1 metric tonne has around the same mass as 1 cubic meter of water or around 1000 litres.

So we are talking about around 15 thousand litres or around 4 thousand gallons.

As you stated, its a fraction of an Olympic sized pool, which usually at a minimum measure in at 500 million gallons (as far as I know this of course is not a hard number as there is no hard depth requirement for Olympic sized pools, merely length and width).

So we are talking less than a percent of a small Olympic sized pool.. (or assuming 500 gallons, 125 times smaller)

Thats a very small amount of water, especially if most of it is going out to sea where it will be diluted into pretty much nothing pretty quickly.

Sure, but 15 metric tons sounds better than 4,000 gallons. Hard to make a point when the subject matter doesn't lend itself well to sensationalism.

Thanks for making the exact point I thought of when I read the title of the article.

Yup. 4000 gallons is about how much water is in the inflatable-ring pool in my backyard. Not a lot by any stretch.

I think that if we don't know how much and with which isotope the water is contaminated there is no news to comment.
