Average Ph Of Well Water

Freshwater ph varies across the world depending on weather patterns human activity and natural processes.

Average ph of well water.

In general a water with a ph 7 is considered acidic and with a ph 7 is considered basic. The ph of pure water is 7. The normal range for ph in surface water systems is 6 5 to 8 5 and the ph range for groundwater systems is between 6 and 8 5. The normal range for ph in surface water systems is 6 5 to 8 5 and for groundwater systems 6 to 8 5.

Decent water companies should produce tap water from ph 7 8 but it is never. For example a 2012 study found that drinking naturally carbonated artesian well alkaline water with a ph of 8 8 may help deactivate pepsin the main enzyme that causes acid reflux. In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic. These filters will typically raise the ph of the well water from 7 0 to 8 0 and add 30 to 100 ppm of hardness depending on the alkalinity and water hardness.

Water with a very low or high ph can be a sign of chemical or heavy metal pollution. Water with a ph of higher than 8 5 can be hard which poses less of a health risk than acidic water but can taste bad and leave. Water with a ph level between 6 and 8 5 is safe to drink because it is neither acidic nor alkaline enough to be dangerous in the human body. One of the most convenient methods to raise well water ph hardness and alkalinity is to use a calcite neutralizer filter.

Acidic well water below ph 7 is caused by dissolved carbon dioxide a lack of calcium or mining or industrial runoff. The ph in well water is determined by the dissolved salts and minerals it contains. Water with a ph of less than 6 can be corrosive and filled with toxic metals. Drinking water must have a ph value of 6 5 8 5 to fall within epa standards and they further note that even within the acceptable ph range slightly high or low ph water can be unappealing for.

These leach out of the surrounding rocks and soil. Alkalinity is a measure of the capacity of the water to resist a change in ph.
