Scientific water testing assesses the composition and quality of water to determine whether it is safe to use or to discharge. Regular testing is essential for individuals and communities and for organizations that use water as part of their manufacturing process or other daily operations. This testing will help you determine whether or not your water sources are safe to work with and how they will affect your local community.
RespirTek can assist with your water testing needs.. Here’s why water chemical tests are so important, how to check water quality, and different types of testing options available.
The Importance of Water Contamination Testing
Many manufacturing processes use large volumes of water daily. Water that is contaminated or polluted will negatively affect these processes.
For example, food, beverages, and medication made with contaminated water could be dangerous to consumers. Additionally, water with chemical or mineral imbalances could damage industrial equipment by causing metal to corrode. On top of that, any polluted wastewater could interfere with local wildlife and even contaminate drinking water in your community.
Using proven water analysis methods helps organizations better understand the makeup of their water supply. This information also informs effective water treatment processes and can also help you stay compliant with sustainability regulations and guidelines.
What Industries Require Water Testing?
There are many industries that require water testing for safe and successful operations. These include:
- Agriculture: Farms and other agricultural businesses use large volumes of water to grow and process their crops. Water testing is necessary to ensure that runoff from irrigation systems isn’t contaminated.
- Pharmaceutical manufacturing: Water used to make pharmaceuticals needs to be completely free of pollutants or viruses. Regular testing ensures that the water supply meets the stringent purity requirements necessary for safe pharmaceutical development.
- Food and beverage: Water is a key ingredient in many food and beverage products. It’s also used to clean manufacturing equipment. Regular testing protects consumers and makes for a safer, cleaner manufacturing process.
- Energy: Water is used in the energy industry for steam generation, cooling systems, and hydroelectric power generation. Testing helps prevent corrosion and other water damage to your systems.
- Tech manufacturing: The process of creating semiconductors and other computer components requires pure water. If water isn’t properly tested and treated, it could prevent these products from working properly.
3 Types of Water Testing Methods
There are three primary methods for water testing analysis. The right approach for your organization will depend on your industry, your water source, and your sustainability goals.
Physical Water Testing Methods
Physical water testing measures the water’s physical features and characteristics. These physical tests provide insights about how the water could affect your manufacturing processes. Here are some key components of physical water testing.
- Color: Visually assessing the water’s color can help you determine if there are suspended or dissolved solids present. Specific colors are associated with common contaminants, so a visual test can help you determine whether or not future treatment is necessary.
- Temperature: The temperature of a water source will affect the way that water behaves in industrial environments.
- Odor: When contaminants are introduced to water, they can change the way that water smells. This physical parameter is often an indication that further testing is needed.
- Conductivity: This test measures the water’s ability to conduct an electrical current. If the water is conductive, it likely contains minerals or other contaminants, as pure water is not typically able to hold an electrical current.
- Turbidity: This test measures the way that light penetrates the water. High turbidity means that the water is very cloudy and blocks light, indicating the presence of solids or contaminants.
Chemical Water Testing Methods
Chemical water testing parameters measure the water’s chemical makeup. High levels of certain chemicals can make water unsafe to consume or can require industrial wastewater treatment before the water can be discharged. Chemicals can also cause buildup and damage to systems.
Here are some key chemical parameters for water testing. Note that chemical tests can be customized depending on your industry and the specific chemicals you are concerned about.
- Chlorine: Water that has been through previous disinfecting processes may contain high levels of chlorine. Excess chlorine could make water too dangerous to consume, although it is safe to consume in mild to moderate levels. Additionally, excess chlorine can cause metal equipment to corrode.
- pH levels: pH tests examine whether water is acidic or basic, and to what degree. This is particularly important when testing wastewater, as water that is too acidic or too basic could harm local wildlife.
- Hardness: These tests measure the mineral levels in the water. Hard water has a high mineral content, and specifically contains high levels of calcium and magnesium. While hard water is safe to consume, it can leave a scaly residue on industrial equipment, which means that it is not ideal for manufacturing.
- Ammonia: Ammonia is a chemical compound that can be dangerous when consumed in large quantities. It is also known for its distinct odor. Ammonia is often present in water that has already been disinfected, or in water where organic matter has previously decomposed.
- Phosphate: Phosphate is a chemical element that is often present in water in many different forms. Although phosphate is not dangerous, it can cause eutrophication, which leads to excess algae growth.
- Nitrogen: Nitrogen in water typically takes the form of nitrite or nitrate. Both forms are dangerous to consume, particularly in high volumes. Nitrate also causes eutrophication and aquatic plant growth.
- Dissolved oxygen: Quality water contains high levels of dissolved oxygen (DO). DO is key for environmental sustainability, especially in wastewater, as it supports healthy aquatic wildlife.
Biological Water Testing Methods
Water pollution tests also involve biological testing. Biological tests look for the presence of specific microorganisms in the water to determine whether it is safe to consume. These tests focus on:
- Bacteria: Bacteria in water results in the transmission of a variety of illnesses. In particular, some strains of the bacteria E. coli are very dangerous to consume. E. coli testing is also often used as an indicator of other bacterial contamination. Bacteria levels are highly dependent on factors like temperature and pH levels, which is why comprehensive testing is necessary.
- Viruses: These tests search for the presence of waterborne viruses, which can cause serious health issues. If viruses are present, water will need to undergo disinfection before it can be used safely. Testing wastewater for viral loads can also be a valuable tool when implemented as part of a public health strategy. Monitoring wastewater for the presence of viruses can be instrumental in the early detection of disease outbreaks and can help public officials ensure that resources are properly allocated.
- Plant life: Biological tests measure algae levels, which can affect the water’s taste and smell. Some algae species are also dangerous to consume.
How to Test Water for Contaminants
If your organization uses water as part of your operations, you may be wondering how to do a water test and learn more about what’s in your water supply.
While there are at-home water testing kits available, they are generally not accurate enough for commercial or industrial use. Field testing, using simple instruments or field test kits, can be an effective way of monitoring some water characteristics, such as temperature, pH, and DO. Laboratory testing is the most effective way to identify contaminants in your water when a high degree of precision and accuracy are required. Working with an experienced testing center will give you the data and analysis you need to implement successful water monitoring and treatment strategies.
A laboratory will help you select the appropriate tests for your needs based on where your water is coming from and your sustainability goals. Testing typically starts with visual and physical assessment. Then, the laboratory conducts biological or chemical tests based on the specific parameters requested.
Key Parameters to Measure in a Water Pollution Test
When determining how to test water for purity, you’ll need to consider which parameters are most important to your operations. Consider local standards for drinking water and sustainability, as well as operational concerns you may have. For example, organizations that rely heavily on metal machinery will want to test for minerals that could cause corrosion or buildup.
When deciding which parameters to test for, you’ll also need to consider where your water is coming from. For example, if your water has already been disinfected, may need to test for chlorine, ammonia, and other chemical byproducts of the disinfection process. Additionally, water sources in some regions are more prone to hardness or algae growth than others, and this could inform your water testing decisions.
Interpretation of Test Results
When you have your water source professionally tested, you will receive a wealth of data and information about the characteristics of your water and what’s in it. This information and data can be compared to suggested levels, regulatory requirements, or historical data to track the quality of your water.
