Though many of us who have lived in the developed world take it for granted, access to clean and safe drinking water is vital to ensuring productive and healthy lives. Unfortunately, many of the poorest people in the world lack sufficient access to potable water and basic sanitation. Clean water and sanitation are linked because limited access to basic sanitation systems (latrines, waste disposal systems, clean water for bathing, etc.) directly affects the ability of individuals to obtain clean drinking water. Lack of sanitation facilities force people to defecate and urinate in rivers, streams, oceans, and other areas where they are also living, playing and preparing food. This significantly increases the risk of transmitting disease. According to the World Health Organization, one gram of feces in untreated water may contain 10 million viruses, one million bacteria, 1000 parasite cysts and 100 worm eggs. Here are some important facts about sanitation and drinking water in the developing world:
- Globally, around 2.6 billion people lack access to adequate sanitation (43% of the world´s population). In Panama, 70% of individuals living in indigenous areas do not have access to potable water in their homes. These individuals are often forced to travel long distances to small rivers and streams. The dry season frequently exacerbates the problem since many existing water systems run out of water.
- Examples of diseases transmitted through water contaminated by human waste include diarrhea, cholera, dysentery, typhoid, and hepatitis A. In Africa, 115 people die every hour from diseases linked to poor sanitation, poor hygiene and contaminated water.
- Diarrhea is a major killer in the developing world and is largely preventable. Diarrhea is responsible for 1.5 million deaths every year, mostly among children under the age of 5 living in developing countries. Hygiene interventions including personal hygiene education and promotion of hand washing leads to a reduction of diarrhea episodes by 45%. Improvements in drinking-water quality through household water treatment (such as chlorination at point of use and adequate domestic storage), leads to a reduction of diarrhea episodes by 39%.
- Every US $1 invested in improved sanitation shows an average of US $9 return in value. Those benefits are experienced specifically by poor children, and in the disadvantaged communities that need them most.
One of the project areas of Peace Corps Panama is Environmental Health. This program focuses on health education, building and promoting the use of latrines, and building and repairing rural water systems. EH volunteers do difficult but important work in some the most rural and isolated parts of the country.
In the recent past, many areas of Panama were negatively impacted by poor access to and quality of water and in many areas, these are still significant threats. We are very fortunate because our community was connected to an underground well system in the 1960s, which has ensured a safe and consistent supply of water ever since. The addition of this water system improved the health and welfare of our community and allowed for increased economic and other social developments. However, nearby communities in our region still rely on above ground aqueduct systems which provide water less consistently and are at greater risk for water contamination. While much progress has been made in Panama, there is still a lot of work that needs to be done to ensure equal access to this vital resource.
