Mineral character
Calcium is 22.5 mg/L, magnesium 11.5 mg/L, sodium 22 mg/L, sulphate 3.7 mg/L, chloride 14 mg/L, and bicarbonate 116 mg/L. Hardness is 104 mg/L as CaCO₃. The profile is soft with moderate bicarbonate. Sulphate is very low at 3.7 mg/L, reflecting the siliceous Cambrian terrain. The balance of calcium and magnesium is closer than in most chalk or limestone waters.
