What is homeland security water treatment?
Treatment of water related to the response to a homeland security incident can use some of the same technologies developed over the past 100 years for treatment in community water and wastewater system. Treatment for homeland security incidents differs, however, in the types of contaminants that can lead to a need to treat the water on-site. Such on-site treatment systems need to be compatible with potentially enormous volumes of contaminated water.
Why is drinking water contaminated?
Drinking water could become contaminated from breaks in pipes that allow contaminants to intrude, intentional tampering, or loss of electrical power and pressure resulting in water stagnation and bacterial growth. Contamination needs to be flushed from the drinking water distribution system and the resultant contaminated water treated. ...
How does stormwater get contaminated?
In addition to contaminated water finding its way into stormwater drainage systems as a result of contamination response activities, stormwater systems, such as detention basins, retention ponds, wetlands, and pipe networks, can become directly contaminated from tanker truck wrecks, train derailments, and pipeline ruptures as well as rain runoff coming from buildings and roads contaminated from a wide-area attack or accident. EPA research is addressing numerous stormwater assets found in urban and suburban areas that can be retrofitted or designed to provide flow control, spillcontainment, and treatment of contaminated water. These retrofit technologies can be used to improve water quality and aquatic habitats in urban areas on a daily basis as well as following an emergency. They do not require manned active operation or control of their operation and can be widely located across a watershed.
How does disposing of waste affect response activities?
Disposal of wastes can impact response activities, especially for types or amounts of contaminants resulting from homeland security incidents.

When were antibiotics invented?
Antibiotics used to be a magic bullet to cure a wide range of diseases. The discovery of penicillin in the late 1920s was a game-changer, as diseases that used to mean certain death suddenly became treatable. But just as humans have found ways to stave off disease, viruses and bacteria have been adapting, too.
How can antibiotic resistance be overcome?
One of the most important steps in combatting drug resistance is to change the way antibiotics are used and prescribed. According to the Centers for Disease Control and Prevention, as much as 50 percent of the time antibiotics are prescribed, they are prescribed incorrectly or in a way that's suboptimal—for example, prescribing antibiotics for what is really a viral infection, like the cold .

How many people die from waterborne diseases?
According to the World Health Organization, waterborne diseases account for an estimated 3.6% of the total DALY (disability- adjusted life year) global burden of disease, and cause about 1.5 million human deaths annually. The World Health Organization estimates that 58% of that burden, or 842,000 deaths per year, is attributable to a lack of safe drinking water supply, sanitation and hygiene (summarized as WASH ).
How does waterborne disease affect the economy?
People who are infected by a waterborne disease are usually confronted with related costs and often a huge financial burden. This is especially the case in less developed countries. The financial losses are mostly caused by e.g. costs for medical treatment and medication, costs for transport, special food, and by the loss of manpower. Many families must even sell their land to pay for treatment in a proper hospital. On average, a family spends about 10% of the monthly households income per person infected.
What is WBDOSS public health?
WBDOSS and the public health community work together to look into the causes of contaminated water leading to waterborne disease outbreaks and maintaining those outbreaks. They do so by having the public health community investigating the outbreaks and WBDOSS receiving the reports.
What is WBDOSS reporting?
WBDOSS relies on complete and accurate data from public health departments in individual states, territories, and other U.S. jurisdictions regarding waterborne disease and outbreak activity. In 2009, reporting to the WBDOSS transitioned from a paper form to the electronic National Outbreak Reporting System (NORS).
What is the WBDOSS system?
The Waterborne Disease and Outbreak Surveillance System ( WBDOSS) is the principal database used to identify the causative agents, deficiencies, water systems, and sources associated with waterborne disease and outbreaks in the United States. Since 1971, the Centers for Disease Control and Prevention (CDC), the Council of State and Territorial Epidemiologists (CSTE), and the US Environmental Protection Agency (EPA) have maintained this surveillance system for collecting and reporting data on "waterborne disease and outbreaks associated with recreational water, drinking water, environmental, and undetermined exposures to water." "Data from WBDOSS have supported EPA efforts to develop drinking water regulations and have provided guidance for CDC’s recreational water activities."
How does poverty affect waterborne diseases?
Poverty also increases the risk of communities to be affected by waterborne diseases. For example, the economic level of a community impacts their ability to have access to filtered water. There are South Asian communities that do not have the economic stability to provide clean water and sewage. Lower income correlates to families spending less money on water supply. Socio-economics correlates to less education, which correlates to less knowledge on waterborne diseases. Less developed areas such as Saggian do not have an existing or sufficient pipe to supply water or sewerage system. Less developed countries might be more at risk for potential outbreaks of waterborne diseases but more developed regions also are at risk to waterborne disease outbreaks. Water supply coming from private owned water supplies has a higher probability of a disease such as gastroenteritis spreading than a public (government regulated) water supply.
How are waterborne diseases transmitted?
Waterborne diseases. Waterborne diseases can be spread via groundwater which is contaminated with fecal pathogens from pit latrines. Waterborne diseases are conditions caused by pathogenic micro-organisms that are transmitted in water.
