Average Ph Of Well Water

Decent water companies should produce tap water from ph 7 8 but it is never.

Average ph of well water.

In general a water with a ph 7 is considered acidic and with a ph 7 is considered basic. Why 6 8 5 ph is ideal for drinking water. 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. 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.

The ph of pure water is 7. 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. Alkalinity is a measure of the capacity of the water to resist a change in ph. The ph in well water is determined by the dissolved salts and minerals it contains.

In general water with a ph lower than 7 is considered acidic and with a ph greater than 7 is considered basic. These leach out of the surrounding rocks and soil. One of the most convenient methods to raise well water ph hardness and alkalinity is to use a calcite neutralizer filter. Water with a very low or high ph can be a sign of chemical or heavy metal pollution.

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. The normal range for ph in surface water systems is 6 5 to 8 5 and for groundwater systems 6 to 8 5. Water with a ph of less than 6 can be corrosive and filled with toxic metals. Alkalinity is a measure of the capacity of the water to resists a change in ph that would tend to make the water more acidic.

Freshwater ph varies across the world depending on weather patterns human activity and natural processes. Acidic well water below ph 7 is caused by dissolved carbon dioxide a lack of calcium or mining or industrial runoff.
