ABSTRACT
Landfills are the most widely used method for garbage disposal. They are filled with different types of garbage including residential and industrial.
Landfills are mostly composed of leachate which is composed of components reportedly harmful to the environment. Leachate is created as rainfall lands on an incapped landfill and percolates through the wastes.
This study aimed to determine and compare the toxicity of leachate collected from Calajunan Dumpsite and water collected from the Calajunan Creek on two months. The leached and water samples were randomly collected for two months and dissolve oxygen.
The PH of the samples gathered on January was higher than that of the samples of September. The DO and alkalinity of the leachate samples gathered on January was higher than that of the leachate samples gathered on September. However, the DO and alkalinity of the water samples gathered on January was lower than that of September’s All parameter fall with in the different water quality standards.
