The arrival of the monsoon brings welcome rainfall, but it also increases the risk of contaminated drinking water. Floodwater, overflowing drains and damaged pipelines may allow harmful microorganisms to enter water sources.
Many illnesses that occur during the rainy season can be prevented by ensuring safe drinking water and maintaining good hygiene practices at home.
Why drinking water becomes unsafe during the monsoon
Heavy rainfall and flooding may contaminate wells, water storage tanks and public water supplies with bacteria, viruses and parasites.
Open wells, damaged pipelines and poor sanitation increase the possibility of contaminated drinking water during the rainy season.
Common diseases linked to unsafe drinking water
Unsafe drinking water may spread illnesses such as acute diarrhea, typhoid fever, hepatitis A, shigellosis and other intestinal infections.
These illnesses can affect people of all ages but may become more serious in children, elderly individuals and those with weakened immunity.
Can contaminated water always be identified
Not always. Water that looks clear, has no unusual smell and tastes normal may still contain harmful microorganisms.
Visual appearance alone cannot confirm that drinking water is safe.
Simple ways to make drinking water safer
Boiling drinking water adequately before consumption remains one of the most reliable methods for reducing many infectious organisms.
Use clean containers with tightly fitting lids for storage and avoid dipping unclean utensils or hands into stored drinking water.
Protecting household wells
Keep wells properly covered and prevent surface water from entering after heavy rainfall. Clean the surrounding area regularly to reduce contamination.
If flooding has affected the well, appropriate cleaning and disinfection should be carried out before using the water again.
Safe food preparation
Use safe drinking water for cooking, preparing beverages and washing fruits and vegetables.
Food prepared with contaminated water may also transmit water borne infections.
Symptoms that may suggest a water borne illness
Diarrhea, vomiting, stomach pain, fever, nausea and loss of appetite are common symptoms of many water borne infections.
Some illnesses may also cause jaundice, bloody diarrhea or severe dehydration.
Who needs extra protection
Infants, young children, elderly individuals, pregnant women and people with chronic illnesses are more vulnerable to complications from water borne diseases.
Extra care should be taken to ensure these individuals receive safe drinking water throughout the monsoon.
When should medical advice be sought
Medical evaluation is recommended if diarrhea becomes severe, persists for several days or is associated with blood in the stool, repeated vomiting, high fever or signs of dehydration.
Prompt medical attention is particularly important for children, elderly individuals and people with weakened immunity.
Safe water is the first step toward a healthy monsoon
Most water borne diseases can be prevented through safe drinking water, proper sanitation, regular hand washing and hygienic food preparation.
Taking simple precautions every day can greatly reduce the risk of illness and help keep families healthy throughout the rainy season.
