The modification was designed to address the long-term persistent effects of contact with low concentrations of As which includes been associated with several health results including malignancies of your skin bladder lung and kidney aswell as cardiovascular pulmonary and neurological results (USEPA 2001 The guideline went into impact in Feb 2002 and general public drinking AZ191 water systems received until January 2006 to comply (USEPA 2001 By 2011 ten years after adoption of the brand new regular the USEPA estimations that almost 800 drinking water systems offering 1.8 million individuals were still not in compliance (USEPA 2013 the majority of that are small rural systems offering significantly less than 3 300 individuals who cannot find the money to meet up the As standard while keeping water affordable.
