Research Papers On Drinking Water Treatment
Groundwater is cheaper to treat, but aquifers usually have limited output and can take thousands of years to recharge.
Surface water sources should be carefully monitored for the presence of unusual types or levels of microbial/disease causing contaminants.
Many environmental and cost considerations affect the location and design of water purification plants.
In past decades, awareness and advancement in water treatment and distribution had allowed many to gain access to improved drinking water sources.
From 1990 to 2005, more than 1.1 billion people worldwide had gained access to improved drinking source, with 83% of people worldwide having access to improved drinking water source.
The use of unimproved water source will cause users to be susceptible to waterborne diseases.
Poor sanitation and hygiene cause pathogens to contaminate surface water and groundwater.
