Groundwater is the lifeblood of our nation. Everyone can and should do something to protect groundwater. Why? We all have a stake in maintaining its quality and quantity. The quality of our groundwater affects every aspect of our lives now and long into the future.
- For starters, 99 percent of all available freshwater comes from aquifers underground. Being a good steward of groundwater just makes sense.
- Not only that, most surface water bodies are connected to groundwater so how you impact groundwater matters.
- Furthermore, many public water systems draw all or part of their supply from groundwater, so protecting the resource protects the public water supply and impacts treatment costs.
- If you own a well to provide water for your family, farm, or business, groundwater protection is doubly important. As a well owner, you are the manager of your own water system. Protecting groundwater will help reduce risks to your water supply.
There are two fundamental categories of groundwater protection:
Before examining what you can do to protect groundwater, however, you should know that sometimes the quality and safety of groundwater is affected by substances that occur naturally in the environment.
Naturally occurring contamination
The chemistry of the groundwater flowing into a well reflects what’s in the environment. If the natural quality of groundwater to be used for human consumption presents a health risk, water treatment will be necessary.
Examples of naturally occurring substances that can present health risk are:
- Microorganisms ( bacteria, viruses, and parasites; these tend to be more common in shallow groundwater)
- Radionuclides ( radium, radon, and uranium)
- Heavy metals ( arsenic, cadmium, chromium, lead, and selenium).
Human activities can pollute groundwater, and this is where every person can help protect groundwater — both in terms of groundwater quality and quantity. Some common human causes of groundwater contamination are:
- Improper storage or disposal of hazardous substances
- Improper use of fertilizers, animal manures, herbicides, insecticides, and pesticides
- Chemical spills
- Improperly built and/or maintained septic systems
- Improperly abandoned wells (these include water wells, groundwater monitoring wells, and wells used in cleaning contaminated groundwater)
- Poorly sited or constructed water wells.
An emerging concern in recent years is the occurrence of pharmaceuticals and personal care products in water. Much research remains to be done to assess the health risks of trace amounts of these items. Learn more about this issue here
Americans are the largest water users, per capita, in the world. In terms of groundwater, Americans use 79.6 billion gallons per day
— the equivalent of 2,923 12-oz. cans for every man, woman, and child in the nation.
is far and away the largest user of groundwater in America at 53.5 billion gallons a day followed by public use via public water systems or private household wells at a combined total of 18.3 billion gallons per day. More efficient use
of water in either of these areas could save a huge amount.
At the household level, the greatest amount of water used inside the home occurs in the bathroom. The remainder of indoor water use is divided between clothes washing and kitchen use, including dish washing, according to the U.S. EPA. Calculate your household water use here
. Depending on where in the country you live, outdoor water use can vary widely. If you want to get an ever better idea how much water you use, find out your “water footprint” by calculating
the amount of water it takes to produce some of the food you consume.
ACT — acknowledge, consider, take action
On Protect Your Groundwater Day, NGWA urges you to ACT. Use this day to begin doing your part for protecting one of our most important natural resources — groundwater
1. Acknowledge the causes of preventable groundwater contamination
- If you own a water well
2. Consider which apply to you
- If you own a water well
3. Take action to prevent groundwater contamination
If you own a water well
- When it comes to hazardous household substances:
- Store them properly in a secure place
- Use them according to the manufacturer’s recommendations
- Dispose of them safely.
- When it comes to water conservation:
