121,000 tonnes of highly contaminated water alone as of June 29, according to TEPCO, an increase of about 16,000 tonnes since the end of May.

From Asahi Shinbun (1:07AM JST 6/30/2011):

東京電力は29日、福島第一原子力発電所1~4号機などにたまった高濃度の放射能汚染水が28日現在で約12万1千トンに上ると発表した。5月末時 点から1万6千トン増えた。内訳は1~4号機の原子炉建屋やタービン建屋などに計約9万9440トン、汚染水を一時保管している集中廃棄物処理施設に計約 2万1730トン。

TEPCO announced on June 29 that the highly contaminated water in the buildings of Reactors 1 through 4 was about 121,000 tonnes as of June 28. It is an increase of 16,000 tonnes since the end of May. There are 99,440 tonnes of water in the reactor buildings and turbine buildings of the Reactors 1 through 4, and 21,730 tonnes in the Central Waste Processing Facility that temporarily stores the highly contaminated water.

 東電は浄化処理を続けることによって、6月29日からの1週間で汚染水を現状から3千トン減らせるとしている。ただし、浄化処理施設の稼働率80%が前提。17日から28日までの実績は約55%で、処理量は約7230トンだった。

TEPCO thinks it will be able to reduce the amount of the water by 3,000 tonnes in one week starting June 29. However, that schedule assumes the water treatment system to run at the operating rate of 80%. From June 17 to 28, the system ran at about 55%, processing 7,230 tonnes of water.

By the way, the water treatment system is stopped again, for yet another unknown reason. On June 29 alone, the system had to be stopped at least twice for water leakage in different parts of the system before the alarm that sounded in the evening shut down the entire system again. TEPCO is investigating.
