STATIC WATER LEVEL

Static Water Level (SWL) refers to the water level in well under undisturbed and no pumping conditions. It gives information how much water is there in the well.
Monitoring the status of SWL will help determine an impending drought or water crisis is on its way, and formulate solutions and policies ahead of the possible crises.

pH

pH is the measure of how acidic or basic water is. An acidic water will have a sour taste (example: vinegar). A basic water will have a bitter and soapy taste (example: detergent).
For Class B waters, the recommended pH range is 6.5-8.5. Outside this range, the water may be unpalatable or not safe for drinking.

ELECTRICAL CONDUCTIVITY

Electrical Conductivity (EC) is the measure of the ability of the water to pass electricity. Any drastic change in electrical conductivity can be an indicator of stress or pollution. The normal electrical conductivity range for drinking water is 200-800 μS/cm. Above the range, the water may be unsafe for drinking since higher electrical conductivity will mean having more dissolved metals in the water. If these metals get into the human’s body, there can be serious health implications (ex: mercury poisoning or the Minamata disease).

TOTAL DISSOLVED SOLIDS

Total Dissolved Solids (TDS) is the overall concentration of metals, organic and inorganic matter in the water. According to USGS, concentrations above the recommended value for drinking water of 500 mg/L is deemed unsafe. Above this value, the water will have undesirable odor and taste that it will not be safe for drinking. The undesirable characteristics of water will be attributed to the dissolved matter in it.

SALINITY

Salinity is the measure of how salty water is. According to Australian Drinking Water Guidelines, the recommended range is 0-900 mg/L. Above 900 mg/L, the water will be too salty and unsafe to drink. Drinking salty water will dehydrate the human body. It will release more water than the volume of water that one drinks. Having too much salt in the body will interfere with the blood circulation, and will become deadly.

Dissolved Oxygen

Dissolved oxygen (DO) is the amount of oxygen that is present in water. Water bodies receive oxygen from the atmosphere and from aquatic plants. Running water, such as that of a swift moving stream, dissolves more oxygen than the still water of a pond or lake.

TEMPERATURE

Temperature is the measure of how hot or cold water is. Hotter waters are more unsafe because it makes toxic metals and pollutants more dissolved and reactive. Hotter waters contain lesser dissolved oxygen, which is essential for life. For Class B waters, the recommended pH is 26-30 Celcius.
