| Water Hardness | \n\t\t|
|---|---|
| The hardness of water in the Affinity Water area occurs naturally and is characterised by the presence of high levels of calcium and magnesium, which are good for healthy teeth and bones. | \n\t\t|
| Calcium | \n\t\t\t111 mg/l | \n\t\t
| Calcium is the principal constituent of hardness. | \n\t\t|
| Total Hardness | \n\t\t\t277 mg/l | \n\t\t
| \n\t\t\t\tTotal hardness is usually expressed in terms of calcium carbonate and is measured in milligrammes per litre (mg/l) which is the same as parts per million (ppm). The recognised classification scheme we are using is: 0-75 soft, 76-150 moderately hard, 151-300 hard, 300+ very hard. \n\t\t\t\t\t\tYour water is hard.\n\t\t\t | \n\t\t|
| Degrees English (or Clarke) | \n\t\t\t19.41 | \n\t\t
| phContent hardness measurement is used on some British appliances. | \n\t\t|
| Degrees German | \n\t\t\t15.53 | \n\t\t
| phContent is used on some German appliances. | \n\t\t|
| Degrees French | \n\t\t\t27.7 | \n\t\t
| phContent is used on some French appliances. | \n\t\t|
| Millimols | \n\t\t\t2.77 mmol/l | \n\t\t
| Millimols per litre. Some appliances refer to water hardness in millimols per litre (mmol/l). | \n\t\t|
| Fluoride | \n\t\t\t0.120 mg/l | \n\t\t
| Fluoride naturally occurs in the water in many areas. Affinity Water does not add any fluoride to your water. Fluoride is measured in milligrammes per litre (mg/l). | \n\t\t
