Aim
Compare the quality of water along the water channel in Zeeland, Netherlands using direct and indirect methods of monitoring pollution.
Research Question
How does the water quality of water channel in Zeeland change with increasing distance from its source (Lake Vroonplas), as measured using direct and indirect water quality monitoring methods?
Environmental Issue: Degradation of water quality due to the increasing numbers of water pollutants Water is an essential element for all living organisms on the Earth. However, out of 2.66% of fresh water covering the Earth, only 0.6% is usable for drinking.1 Yet, humans continue to contaminate the limited water sources by releasing the harmful pollutants without proper management. Water is known as “universal solvent”, due to its ability to dissolve more substances than any other liquid on the planet.2 As a result, water is particularly vulnerable to the pollution as the toxic substances easily dissolve into it.
Nevertheless, 80% of global wastewater is dumped untreated into our waterways.3
According to a report published by the Food and Agriculture Organization, unsustainable agricultural practice is a leading cause of the water pollution worldwide.4 Researchers argue that a range of agricultural activities from livestock productions, expansion of irrigations to the overuse of fertilizers and pesticides have considerable impact on water pollution. For instance, the rain washes away the animal wastes and fertilizers into our waterways, resulting in the nutrient pollution due to excessive inputs of nitrogen or phosphorus. Such water pollution can have harmful impacts on human-beings, livestocks and the environment. In fact, the waterborne diseases are responsible for more than 2 million deaths every
year according to the World Health Organization.5
