Should You Be Concerned?
Every day Americans drink more than one billion glasses of water! We also depend on water in our homes to clean, cook, fix baby food and formula, and bathe. If you are like most people, you trust that your water is safe. This is mostly true. Public drinking water in the US is safe for most healthy people. If you have a well or other private water supply, its up to you to keep your drinking water safe. Whether your water comes from a public or private source, you can take steps to make sure its safe for you and your children.
There are times when your home water supply may not be safe. Using unsafe water to drink or prepare food can make you sick. Children may have more problems than adults because:
What May be in Drinking Water that is Not Safe?
Bacteria and viruses can cause diseases. Drinking water with these germs may cause upset stomachs, diarrhea, or more serious illnesses. It can be worse for children, pregnant women, and sick or older people. Just one drink of water with these germs can make you sick.
Nitrate gets into water from animal and human waste, and from fertilizer. Too much nitrate in your drinking water can cause blue baby syndrome in babies under 6 months old. Babies with this problem often have blue or purple-colored faces because they do not get enough oxygen in their blood. They need to see a doctor right away. Some experts believe nitrate may also result in birth defects and miscarriages. Baby food or formula made with your drinking water needs to be safe.
Lead and copper are metals that can get into water from your pipes. Too much lead can cause children to have learning and behavior problems, and other illnesses. (Click here for more information on lead.) Babies who get too much copper can have colic and spit up their formula more than normal. Older children and adults may have upset stomachs or diarrhea from copper.
Other harmful chemicals can get into drinking water. Pesticides may get into your water supply by washing off lawns and fields or leaking from storage containers. Gas or oil can seep into the ground and get into drinking water. Even very small amounts of some chemicals can cause problems, such as damage to kidneys, liver, or other organs. Some cause cancer and others can cause problems if you are pregnant.
Answer the questions below to find out if your water is safe and what you can do to cut down on risks to your family.
Questions to ask?
Where Does Your Water Come From?
Does your water come from a public water supply, such as the water utility in your city or town? Or do you have a private water supply, such as a well or a spring? The questions to ask yourself are different depending on where your water comes from.
Public Water Supplies
Before reaching your house, water from a public water supply is tested for over 80 different kinds of chemicals. If there are problems, the company has to treat the water to make it safe or tell you that the water is unsafe to drink.
Every year, water companies give the results of these water tests to customers. They mail reports or print them in a local newspaper. You can also call your water company to ask what chemicals are found in the water and how they treat it to make it safe.
Public water can become unsafe after it gets to your home from lead or copper pipes. What kind of pipes do you have?
Clear the Pipes -- Follow this simple step if lead or copper are problems in your home.
When you haven't used your water for a while (like when you wake up in the morning or when you get home from work), you need to clear out the pipes. Let the cold water run for two or three minutes or until you feel the temperature change, before you drink it or use it for cooking. This will flush out water that has sat in the pipes and picked up lead or copper. Never use hot water from the tap for cooking, drinking, or making formula because the heat helps dissolve the metals faster. Use cold water and heat it on the stove or microwave.
Help protect water supplies
You may not know it, but the public water supply is local. Your water may come from the groundwater under your home. It may be the river or lake nearby. What you can do to help keep it clean pollute it.
Private Water Supplies
You may have a private water supply, such as a well, for your drinking water. Your well is your responsibility. You need to make sure it is clean and safe.
Test your well water
Has it been more than two years since your water was tested? You cannot see, smell, or taste most problems so you need to have your water tested at a laboratory. Well water is usually tested for bacteria and nitrate. You may want to have your water tested more often, or for other pollutants, like pesticides, if you have had problems in the past. Call your local or state health department to find out how to have your water tested.
Protect Your Water Supply
You need to take care of your well, especially if it is old.
Do you know where your water well is? Find your well. Is it uphill from animal pens, manure, pet waste, septic systems, dumps and places where chemicals are stored?
What kind of well do you have?
If you do not know what kind of well you have, contact a local well driller. You can find one in the telephone book.
Do you know how old your well is? If it is more than 20 years old, it may need a checkup. You may need to test your water more often.
Is your well in good shape? You want to keep things from above ground out of your water supply.
Do you have unused wells on your property? Unused wells that have not been properly filled and capped can let pollution into groundwater and make your drinking water unsafe. If you have an unused well, ask your local or state health department how to seal it.
Use devices on the ends of faucets to keep water from flowing back into your water supply. These are called back flow prevention devices. They help keep pollutants from washing back into the hose and into your drinking water.
What kind of pipes do you have? See the section on "Clear the Pipes" to find out how to make sure harmful metals are not getting into your drinking water from your pipes.
