Virginia Department of Health urges caution after heavy rains

Increased potential release of inadequately treated wastewater

RICHMOND, Va. – After heavy rain events in parts of the state this week, the Virginia Department of Health (VDH) urges people to take precautions to avoid flooded areas, and once the sun comes out, be aware of potential health risks.

The department says heavy rains can increase the risk of animal waste and the potential release of inadequately treated wastewater from sewage treatment plants.

Bacteria, debris, and other pollutants in rainwater runoff end up in rivers, lakes, and streams, which can pose risks to human health and safety. 

VDH says the most common illnesses from contaminated water are gastrointestinal illnesses. This may cause vomiting, diarrhea, nausea, abdominal pain or fever. 

VDH recommends the following safety tips for people planning to swim, wade, kayak, canoe or go rafting in Virginia natural waters after heavy rain:

  • Avoid getting water in your mouth. Never swallow water from an untreated water source
  • Don’t swim if you have broken skin. Bacteria, viruses and other organisms can infect wounds causing more serious illness
  • Shower with soap and water after recreating in natural waters
  • Don’t swim when you are ill
  • Avoid swimming if dead fish are present.
  • Use extreme caution and avoid unnecessary risks if you encounter covered roads or fast-moving waters. The water may be deeper and moving faster than you think.

Residents or facilities that provide water to the public including campgrounds, restaurants, summer camps, or daycares with private wells or septic systems submerged by flood waters should also take extra precautions.
