community filters have been installed under the DART programme alone. Through the programme, individuals can buy the filters for between 3,500 and 5,000 takas (US$50–70). For the very poorest, the filters are available at 10 per cent of the full price. Nevertheless, some people cannot afford filters and continue to drink arsenic-contaminated water. Other programs distribute filters for free. For example, of 32,500 Sono filters installed until 2008, two-thirds were distributed for free. In 2016 a report by Human Rights Watch noted that the government has failed to address the issue of arsenic contamination adequately due to "nepotism and neglect" so that 20 million people still drink water with higher than permissible arsenic levels.
