Safe Drinking Water Act Latino and African American populations are at higher risk of exposure to drinking water contaminants. Contaminants found in the drinking water of such communities include nitrates, coliform, and lead, which have been linked to cancer, reproductive health problems, gastrointestinal illness, and other health problems. One study found that levels of contaminants in the drinking water of two Nebraska Native American reservations were significantly higher than regional contaminant levels. Another study found that Latino residents in Tucson, Arizona, had higher than average levels of contaminants in their drinking water, which were linked to higher rates of cancer and neurological disorders among
Oil–water separator solids from the disposal fluid and thus avoids injectivity impairment caused by solids plugging. Simultaneous injection using DOWS minimizes the opportunity for the contamination of underground sources of drinking water (USDWs) through leaks in tubing and casing during the injection process. Bioremediation is the use of microorganisms to treat contaminated water. A carefully managed environment is needed for the microorganisms which includes nutrients and hydrocarbons such as oil or other contaminates, and oxygen. In pilot scale studies, bio-remediation was used as one stage in a multi-stage purification process involving a plate separator to remove the majority of the contaminants and
