Assessment of Kalubihon Spring as a feasible water source for Iligan City

NAWASA

Noemi Angel S. CabardoJuliu Curr V. Maghinay

Rationale

Water has always been an important necessity for us humans. Water is used on many things but its main use is for drinking. A permanent water source should be maintained to provide all the water consumption of all the residents in a particular city. One water source cannot sustain the needs of a whole barangay that is why; Iligan City NAWASA (National Water and Sewerage Authority) must have an alternative water source to solve these kinds of problems.

Another water source is the Kalubihon Spring which is not yet considered by Iligan City NAWASA as an alternative source. This study was conducted to assess the feasibility of Kalubihon Spring as an alternative source for Iligan City NAWASA

Statement of the ProblemMain Problem: Is Kalubihon Spring a feasible water source

for NAWASA?Sub-problem:Does the Kalubihon water source pass the qualities of a

feasible water source for Iligan City NAWASA in terms of: turbidity pH level water pressure total dissolved solids (TDS) toxicity

Scope and Limitations of the Study

This study is limited to investigate only one local water source in Iligan City namely the Kalubihon Spring. Investigations of physical and chemical attributes were limited to the water’s turbidity, pH level, TDS, and toxicity. The determination of water pressure was improvised from the standard procedure which used a barometer to measure the atmospheric pressure and using a water pressure meter to measure the volume of water released in a given time.

Some tests actually underwent some laboratory processes such as the TDS and pH level. The experiment will be conducted during the school year 2011-2012

General Procedure

Collection of Water SamplesWater samples were collected directly

from the pipe. Ten 200 mL water containers were filled with water from the Kalubihon Spring. The turbidity test and water pressure test were done on site.

Turbidity Testing

Water samples were collected and the results were compared to the picture below.

Determination of water pressureThe water pressure of the Kalubihon

Spring was determined by using this formula:

Measuring the TDSThe TDS was measured using the TDS

meter.Measuring the pH level

The pH level was used using the pH meter.

Toxicity TestThe toxicity test was done using the

Brine Shrimp Test.

There is no significant difference in the pH level, TDS, toxicity and turbidity between the water from Kalubihon Spring and the standards from NAWASA.

There is a significant difference in the water pressure of the Kalubihon Spring and the standards from NAWASA.

If the water pressure of Kalubihon Spring will then be increased there will be a possibility that Kalubihon Spring can be a feasible water source for NAWASA.

Recommendations

Based on the findings and conclusion of the study, recommendations were then drawn. The sampling process should be done during the rainy season and also during the dry season. During the sampling process, temperature should also be taken into consideration. Methods on how to increase the water pressure must also be a part of the study.

Thank you for listening!!!!

Other factors that affect the quality of groundwater source must be taken into consideration such as the hardness of the water, salinity and the odor. The bacteriological content, such as the total coli form bacteria and E. coli content of the water source should be taken. Some minerals in the drinking water should also be evaluated.
