In the United States, it is largely regulated by the Clean Water Act (CWA). [1] Among other things, the Act requires dischargers to obtain a National Pollutant Discharge Elimination System (NPDES) permit to ...
Cancer mortality rates are determined by the complex relationship of a population's health and lifestyle with their healthcare system. In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1]
The rates of certain types of cancer exceed that of the general population of the United States. For instance, in 2001–05 Native American males were twice as likely to have liver cancer than in white males. Women are 2.4 times as likely to contract and die from liver cancer as their white counterparts.
