It occurred on 26 April 1986 in the No.4 light water graphite moderated reactor at the Chernobyl Nuclear Power Plant near Pripyat, in what was then part of the Ukrainian Soviet Socialist Republic of the Soviet Union (USSR).The event occurred during a late-night safety test which simulated a station blackout power-failure and in which safety systems were deliberately turned off.A combination of inherent reactor design flaws and the reactor operators arranging the core in a manner contrary to the checklist for the test, eventually resulted in uncontrolled reaction conditions.It provides updated data and information related to exposure to lead in Canada, to analytical methods and to treatment approaches available at the municipal and residential scales. Based on these considerations, the document proposes a MAC of 0.005 mg/L for total lead in drinking water.
