I have a deep well, should I care about water purification?
Having a deep well can provide you with a more protected water source compared to surface water, as the depth often shields the water from many contaminants. However, it is not completely immune to pollution. Here are some reasons why you might still consider water purification for a deep well:
- Groundwater Contaminants: While deep wells are less susceptible to contamination from surface activities, they can still be affected by substances like heavy metals (such as lead and arsenic), certain minerals (like fluoride and radon), and nitrates/nitrites, which can seep into groundwater.
- Microbial Pathogens: Bacteria, viruses, and parasites can sometimes find their way into a well, particularly if it’s been compromised by cracks, a faulty seal, or after flooding.
- Chemical Runoff: Agricultural runoff, industrial spills, or improper disposal of chemicals can lead to contamination of groundwater.
- Maintenance and Construction Issues: A well’s integrity can be compromised by poor construction, lack of proper maintenance, or damage over time, leading to contamination.
- Natural Disasters: Events like earthquakes and floods can introduce contaminants into well systems that were previously safe.
- Regulatory Standards: Private wells are not regulated by the Environmental Protection Agency (EPA), so it’s up to the well owner to regularly test and treat the water to ensure it meets health standards.
Are there tools to test my water?
Yes, there are several tools and kits available for testing your water, especially if you’re relying on a private well or another source that is not regulated by municipal authorities. Here’s a rundown of some common water testing options:
These kits are readily available at hardware stores or online and can test for a variety of common contaminants, such as:
- pH levels
- Nitrates and nitrites
- Chlorine levels
- Bacteria presence
They usually come with strips that change color according to the presence and concentration of specific contaminants. You compare the strip to a color chart provided with the kit to determine the levels of different substances.
These are electronic devices that can provide a more precise measurement of certain water quality indicators like pH, total dissolved solids (TDS), and sometimes even specific chemicals. They are typically more expensive than basic test kits but offer more accurate readings.
Mail-In Testing Services
For a comprehensive analysis, you can collect samples of your water and send them to a professional laboratory. They can test for a wide range of potential contaminants, including bacteria, heavy metals, organic compounds, and others that may require more sophisticated detection methods. This is often considered the most accurate way to test water quality.
Water Testing Meters
These meters are more advanced and can provide instant readings for specific contaminants. Some are designed for home use and can measure things like TDS, pH, and conductivity. Others are more specialized and may be used by professionals to detect specific chemicals.
County Extension Offices or Local Health Departments
Sometimes, these local resources offer water testing services or test kits for residents. They can also provide advice on what particular contaminants you should test for based on local water quality issues.
Test Strips for Specific Contaminants
If you’re concerned about a specific contaminant, such as lead or pesticides, you can purchase test strips designed to detect only that particular substance.
Radon Test Kits
Since radon is a radioactive gas that can contaminate water and is a risk factor for lung cancer, specific radon test kits are available for testing your water if you live in an area where radon is a known problem.
Bacteria Test Kits
These kits allow you to test for coliform bacteria, which are a common indicator of sanitary quality in drinking water.
I’m on city water and it got cut off, what now?
If your city water supply is interrupted, it can be due to various reasons such as maintenance work, infrastructure failure, natural disasters, or other emergencies. Here are steps you can take to ensure you have access to water:
- Check for Notices: Sometimes, the city will send out notices about planned interruptions. Check your local government or utility’s website or contact them for information.
- Use Your Reserve: If you’ve prepared for emergencies, you might have bottled water stored. The CDC recommends storing at least 1 gallon of water per person per day for at least three days for drinking and sanitation.
- Collect Water: If there’s advance notice, fill bathtubs, sinks, and other containers with water. This water can be used for flushing toilets or for sanitation purposes.
- Water Heater: Your home’s water heater can be a source of potable water. Turn off the power to the unit, close the incoming valve, and use the spigot at the bottom to collect water.
- Toilet Reserve: The tank (not the bowl) of your toilet often holds a couple of gallons of clean water that can be used in an emergency.
- Rainwater Collection: Setting up a rainwater collection system can provide a supplementary water source.
- Water Purification: Have on hand water purification methods found in this post.
- Portable Water Containers: Keep large water containers that you can use to transport water from a community center or emergency water distribution site back to your home.
- Alternative Sources: Identify alternative water sources nearby, such as rivers, lakes, or a neighbor’s well. Remember, water from these sources may need to be purified.
Primitive Water Purification Techniques for Survival Situations
In the face of an emergency or in a survival scenario, one of the most critical skills you can possess is the ability to purify water. Without access to modern infrastructure, knowing how to clean and purify water using primitive methods can mean the difference between life and death. Here are some time-tested, primitive water purification techniques that anyone can use in the wild or during a disaster.
Boiling: The Gold Standard of Water Purification
Boiling is the simplest and most effective method to purify water. When you boil water, you kill nearly all harmful pathogens present, including bacteria, viruses, and protozoa. The process is straightforward: bring the water to a rolling boil for at least one minute. If you’re at altitudes above 5,000 feet, extend the boiling time to three minutes due to the lower boiling point of water at higher elevations.
Solar Water Disinfection (SODIS): Harnessing the Power of the Sun
SODIS is a method that uses solar energy to disinfect water. Fill clear plastic bottles with water and place them under full sunlight for at least six hours. The ultraviolet radiation, along with the thermal treatment from the sun’s heat, works to eliminate pathogens. This method is ideal in sunny climates and requires minimal resources.
Sedimentation: The Art of Patience
Sometimes the simplest way to start purifying water is by letting nature take its course. Sedimentation involves letting heavy particles in the water settle to the bottom naturally. After some time, you can gently collect the clearer water from the top. This method is often used as a preliminary step before further purification.
Sand and Charcoal Filtration: A DIY Filtering Solution
Creating a makeshift filter using layers of sand and charcoal can significantly improve water quality. The sand acts as a physical filter, trapping particulates, while the charcoal helps in removing certain chemicals and pathogens. This method won’t make water completely safe for drinking on its own but can be used before boiling or chemical treatments.
Cloth Filtration: A Quick Pre-Filter Option
In situations where you need to remove large sediments quickly, a piece of cloth can serve as an effective pre-filter. Pouring water through a clean cloth can help eliminate larger particles and some pathogens. It’s a quick step to prepare water for finer purification methods.
Natural Plant Filtration: Living Filters
Certain aquatic plants, such as cattails and reeds, are natural water purifiers. These plants absorb contaminants from the water, acting as living filters. In a survival situation, funneling water through a dense patch of these plants can help reduce pollutants.
