“Drinking water contains complex mixtures of contaminants, yet government agencies currently assess the health hazards of tap water pollutants one by one,” said Sydney Evans, lead author of the paper and a science analyst at EWG. “In the real world, people are exposed to combinations of chemicals, so it is important that we start to assess health impacts by looking at the combined effects of multiple pollutants.” This cumulative approach is common in assessing the health impacts of exposure to air pollutants but has never before been applied to a national dataset of drinking water contaminants. This model builds on a cumulative cancer risk assessment of water contaminants in the state of California and offers a deeper insight into national drinking water quality. As defined by US government agencies, the calculated cancer risk applies to a statistical lifetime, or approximately 70 years.
Understand hormones. Recent research suggests that short-term (less than five years) use of HRT is not associated with an increase in the risk of breast cancer, but that using it for more than ten years might be. Breast cancer is detected earlier in women using HRT, as they are more alert to the disease than other women.
Most of the increased cancer risk is due to contamination with arsenic, the byproducts of chemical disinfectants and radioactive elements such as uranium and radium. Water systems with the highest risk tend to serve smaller communities and rely on groundwater. These communities often need improved infrastructure and resources to provide safe drinking water to their residents. However, large surface water systems contribute a significant share of the overall risk due to the greater population served and the consistent presence of disinfection byproducts.
The number of cancer cases from water contamination is small compared with the total number of cancer cases in the US. Nevertheless these are cancers that could be prevented with better regulation,“The vast majority of community water systems meet legal standards,” said Olga Naidenko, Ph.D., EWG’s vice president for science investigations. “Yet the latest research shows that contaminants present in the water at those concentrations – perfectly legal – can still harm human health.” “We need to prioritize source water protection, to make sure that these contaminants don’t get into the drinking water supplies to begin with,” Naidenko added.
Make A Natural Beauty Mask To Restore And Hydrate Tired Dull Skin. Oats have moisturizing, anti-inflammatory, and healing properties. Avocado is hydrating and nourishing, with naturally occurring vitamins A and E. And, Yogurt contains nutrients, enzymes and active cultures that help reduce inflammation and balance the pH of your skin for a healthy skin microbiome. In a bowl, blend together 1/4 cup oat flour (ground uncooked oats), 2 Tablespoons unsweetened yogurt and ¼ of an avocado. Mix well and then apply enough to cover your clean, dry face. Leave on face for 10 to 20 minutes and then remove with warm, wet washcloth, and then rinse face with water and pat dry. Use the mask once per day as needed.
Those who are concerned about chemicals in their tap water can install a water filter to help reduce their exposure to contaminants. Filters should be targeted to the specific contaminants detected in the tap water.
