A dose of lead that would have little effect on an adult can have a significant effect on a child. Lead pipes are the main contributor to high lead levels in tap water. Water filters can remove most lead from your drinking water. Rather, it is intended to let you know about the most significant and probable health effects associated with lead in drinking water.The Safe Drinking Water Act requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur with an adequate margin of safety. Residents in some homes in Montreal and Regina, in the western prairies, are among those drinking and cooking with tap water with lead levels that exceed Canada’s federal guidelines.
Human skin does not absorb lead in water. It is much more likely to be tiny air bubbles from a bit of trapped air in your water supply. As a result, the amount of lead in our blood now is much less than it was 30 years ago.First, try to identify and remove the lead source.
Private wells more than 20 years old may contain lead in the “packer” element that is used to help seal the well above the well screen. EPA has set the maximum contaminant level goal for lead in drinking water at zero because lead is a toxic metal that can be harmful to human health even at low exposure levels.
Do not use hot tap water to make cereals, drinks or mix baby formula. Water that's safe to drink should ideally be clear with no odor or funny taste. Running water: In older properties with lead pipes or fittings, run the cold water for at least 1 minute before use. The degree of exposure depends on the concentration of lead, route of exposure (air, water, food), current medical condition, and age. If it is not possible or cost-effective to remove the lead source, flushing the water system before using the water for drinking or cooking may be an option. Infants who consume mostly mixed formula can receive 40 percent to 60 percent of their exposure to lead from drinking water.EPA issued the Lead and Copper Rule in 1991 and revised the regulation in 2000 and 2007. Lead is persistent, and it can bioaccumulate in the body over time.Young children, infants, and fetuses are particularly vulnerable to lead because the physical and behavioral effects of lead occur at lower exposure levels in children than in adults. For the past year and a half, citizens of Flint, Michigan have struggled to find clean, safe water to drink--it appears to contain high levels of lead.
This can result in serious effects to the mother and her developing fetus, including:Corrosion is a dissolving or wearing away of metal caused by a chemical reaction between water and your plumbing. These non-enforceable health goals, based solely on possible health risks, are called maximum contaminant level goals (MCLGs). Any time a particular faucet has not been used for several hours (approximately 6 or more), you can flush the system by running the water for about 1-2 minutes or until the water becomes as cold as it will get. States may set more stringent drinking water regulations than EPA.Lead is also harmful to adults. Lead pipes are more likely to be found in older cities and homes built before 1986. Ironically, this is a common occurrence in tap water, and it is not likely a sign of contamination. Corrosion of pipes and fixture parts can cause the lead to get into tap water.Lead is found in many different materials. When this gas is exposed to certain bacteria, it converts into sulfate, which can cause dehydration or diarrhea. Signs of Drinking Water Contamination.
One way to tell if water is contaminated is to look for turbidity, or cloudiness.
