WASH is a collective term used to represent a growing sector that focuses on water, sanitation, and hygiene. While each of these areas are their own field of study and work, their connectivity and interdependence are widely understood, and therefore grouped together. Work on water and sanitation in this space focuses on access to safe drinking water and sanitation respectively – with the ultimate goal of improved public health and wellbeing. Hygiene-based work is more focused on good handwashing practices, and is less relevant to the immediate problem of ocean wastewater pollution; but is not unrelated, as sick people have the potential to lead to disease spread in the marine environment. Much of the work in this space is working to address an immediate need; for example, people must have access to safe drinking water immediately and consistently. So, rather than look at systemic causes of dirty water and addressing them, those in the WASH sector are more likely to provide a solution that produces immediate results, such as chlorine tablets for drinking water. The same goes for sanitation – a pit latrine is better than no toilet at all, despite the fact that the pit latrine is likely to pollute the environment in which people live, ultimately causing other illness somewhere down the line. Working with this sector to solve these problems at a more holistic level will be good for both the WASH sector and the environmental sector. Many times, nature can provide solutions to the problems the WASH sector is facing. Additionally, often the goal of separating people from their waste leads to the ocean or other aquatic habitat becoming the destination, and therefore the solution for that waste. Working with the WASH sector to avoid the unintended consequences of efforts to protect public health can result in better outcomes for both people and nature. Examples of sustainable sanitation groups and tools include:
