The most common illness associated with swimming in water polluted by sewage is gastroenteritis. They require little or no treatment or get better quickly upon treatment, and they have no long-term health effects. Fortunately, while swimming-related illnesses are unpleasant, they are usually not very serious. In addition, pollution is created by people who leave trash or animal wastes at beaches.Ī sign recommending no swimming because of high bacteria levels.Ĭhildren, the elderly and people with weakened immune systems are the most likely populations to develop illnesses or infections after coming into contact with polluted water, usually while swimming. Pollution can also come from high concentrations of farm animals like pigs and chickens that can contaminate local waterways with runoff, which is then carried to beaches and swimming areas. Polluted runoff (water that drains after rainfall) and untreated sewage released into the water can expose swimmers to harmful microorganisms called “pathogens.” These pathogens can be present at or near the site where polluted discharges enter the water. In the event that beaches are closed or advisories are posted, it is most often because water samples for certain bacteria indicate that harmful bacteria, viruses, protozoa, or parasites are likely present in the waters. EPA also supports monitoring and notification efforts by local beach programs by providing grant money.
