Our new home came with two wells on the property, so we have our own water supply. We had the wells tested and treated. The water is filtered and there is also a water softener that uses sodium tablets.
I have been a little concerned about the spots on our dishes, which tells me the salt makes its way into our drinking water… and I was in no position to evaluate the report showing the mineral content of the water, although someone said it was good.
Then tonight, I stumbled on information concerning this very issue… minerals and their association with cancer. Below is one study that shows that calcium and magnesium are necessary for those working their way to good health after breast cancer. J bought us a water dispenser so I will be using that water in my PUR filter and teapot from now on!
According to Nutritional Solutions (who guide my supplement and diet regimen):
“The risk of BREAST CANCER mortality may also be associated with water hardnesss. Age-adjusted mortality rate for breast cancer was compared among municipalities with different levels of magnesium and calcium in drinking water. After adjusting for fertility rates and urbanization, there was a significant inverse relationship between the levels of calcium and magnesium in drinking water and risk of death from breast cancer.
Risk of OVARIAN CANCER mortality was reduced, 29-43%, in those with higher magnesium levels in their drinking water.
Risk of ESOPHAGEAL CANCER mortality was 25-30% reduced in those with higher magnesium levels in their drinking water. “
Below are studies they refer to:

The relationship between mortality from breast cancer and the levels of calcium and magnesium in drinking water was examined using an ecological design. The study area consisted of 2.52 municipalities in Taiwan. Data on the levels of calcium and magnesium in drinking water were collected from the Taiwan Water Supply Corporation (TWSC). The age-standardized mortality rate (ASR) for breast cancer ( 1982-1991) was compared among municipalities with different levels of magnesium and calcium in drinking water. Weighted multivariate regression analysis was used, and after adjusting for fertility rates and urbanization, there was a significant inverse relationship between the levels of calcium and magnesium in drinking water and risk of death from breast cancer.

The possible association between the risk of rectal cancer and the levels of calcium and magnesium in drinking water from municipal supplies was investigated in a matched case-control study in Taiwan. All eligible rectal-cancer deaths (986 cases) of Taiwan residents from 1990 through 1994 were compared with a sample of deaths from other causes (986 controls), and the levels of calcium and magnesium in the drinking water of these residents were determined. Data on calcium and magnesium levels in drinking water throughout Taiwan were obtained from the Taiwan Water Supply Corporation (TWSC). The control group consisted of people who died from other causes, and the controls were pair-matched to the cases by gender, year of birth and year of death. Compared with those with calcium levels below 22.0 mg/liter, the adjusted odd ratios (95% confidence interval) were 0.72 (0.53-0.98) for the group with water calcium levels between 22.0 and 40.8 mg/liter and 0.63 (0.45-0.87) for the group with calcium levels of 40.9 mg/liter or more. The adjusted odd ratios were not statistically significant for the relationship between magnesium levels in drinking water and rectal cancer. The results of the present study show that there may be a significant protective effect of calcium intake from drinking water on the risk of rectal cancer.
