The EPA’s current drinking water standards are specifically designed to protect children and adults. The standards take into account the potential effects of contaminants on segments of the population that are most at risk. When the EPA sets each standard, the agency conducts a risk assessment, in which scientists evaluate whether fetuses, infants, children, or other groups are more vulnerable to a contaminant than the general population. The standard is set to protect the most vulnerable group.
Often, children are not the most vulnerable group. For example, even though children may be more vulnerable to microbial contaminants than the general public, people with weakened immune systems are even more at risk. People with weakened immune systems include those who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, such as lupus or Crohn’s disease, or those under-going chemotherapy. If the EPA finds that children are the most vulnerable, their risk becomes the most important factor considered in developing the standard. Standards for lead, nitrates, and nitrites are specifically based on risk to children because they are the most vulnerable to these contaminants. If a group other than children is the most sensitive, children are automatically protected.
For most drinking water contaminants the EPA regulates, there is little data to indicate whether children are more sensitive than the general public. However, the EPA is undertaking research to address this important issue. Children, especially infants, drink more fluid per pound of body weight than adults. Very young children’s immune systems are not yet fully developed, making them less able than healthy adults to fight microbes in drinking water. These microbes may induce diarrhea and vomiting, which may cause children to become dehydrated more quickly than adults. Children may also be more susceptible to chemical contaminants that affect learning, motor skills, and sex hormones during important stages of growth.
Despite high confidence in existing standards, the EPA is conducting additional research regarding possible impacts of various contaminants on children and other vulnerable populations, and on new and emerging contaminants. For example, EPA is conducting risk assessments that will consider infants’ and children’s sensitivity and exposure to certain pesticides. The EPA is committed to using the best available, peer-reviewed science and data in developing new standards and reevaluating existing ones. Also, the EPA continues to monitor localized health problems, including outbreaks caused by microbial contaminants in drinking water and other health problems that may be associated with other contaminants (e.g., solvents and other industrial chemicals).
Although the EPA makes every effort to ensure that the drinking water for both adults and children is a safe as possible, many families have opted to take their own steps to make sure the water they drink is the healthiest available. More and more homes now use one type or another of water filtration system or water purifier. From basic filtration pitchers to highly efficient reverse osmosis units, products for filtering drinking water are being purchased by homeowners who have decided to take matters into their own hands.

Installing a drinking water filter in your home may be common practice, but what about a 



The acronym “RV” stands for recreational vehicle, usually defined as a piece of enclosed equipment that can be used both as a vehicle and a temporary travel home. RVs are also commonly referred to as motor homes or sometimes just as a brand name like “Winnebagos”. They are designed for everything from vacations to camping to part- or full-time living, for which they are often parked in special parks designated specifically for them. RVs are available to rent in most major cities and popular tourist destinations.
