paragraph_text: Health issues due to low quality
  
  Contaminated water is estimated to result in more than half a million deaths per year. Contaminated water together with the lack of sanitation was estimated to cause about one percent of disability adjusted life years worldwide in 2010. According to the WHO, the most common diseases linked with poor water quality are cholera, diarrhea, dysentery, hepatitis A, typhoid, and polio.
  
  One of the main causes for contaminated drinking water in developing countries is lack of sanitation and poor hygiene. For this reason, the quantification of the burden of disease from consuming contaminated drinking water usually looks at water, sanitation and hygiene aspects together. The acronym for this is WASH - standing for water, sanitation and hygiene.
  
  The WHO has investigated which proportion of death and disease worldwide can be attributed to insufficient WASH services. In their analysis they focus on the following four health outcomes: diarrhea, acute respiratory infections, undernutrition, and soil-transmitted helminthiases (STHs). These health outcomes are also included as an indicator for achieving Sustainable Development Goal 3 ("Good Health and Wellbeing"): Indicator 3.9.2 reports on the "mortality rate attributed to unsafe water, sanitation, and lack of hygiene".
