- How Can Hanna Help with Your Water Quality Testing?
Water quality is a measure of water's suitability to be used for a specific purpose, such as swimming, farming, or power generation. Water that is considered unsuitable for one application may be perfectly acceptable for another purpose. Quality is a statement of the physical, biological, and chemical characteristics of water based on key condition...
Calibration is an essential step to getting accurate and repeatable results. Ideally, you should calibrate your testing equipment prior to use on the day of sampling. A post calibration check at the end of the day can be performed to determine if the instrument drifted out of calibration. Depending on the nature of your project, you may need to per...
There are a number of parameters that can be measured to indicate water quality. These parameters can be a measure of physical characteristics such as pH, conductivity, or temperature; a statement of the levels of various nutrients in water, such as nitrates and phosphates; or an indication of key elements and compounds in water, such as dissolved ...
What is pH?
pH is a measurement of the relative concentration of hydrogen ions and hydroxide ions in water. The scale ranges from 0 to 14, with 0 being a strong acidic solution and 14 being strongly basic.
Why is measuring pH important?
pH is a way to evaluate the suitability of water for living plant and animal organisms. If water has become too acidic or basic due to natural or man-made pollutants, there can be a profound negative impact on aquatic life. pH is considered normal in a body of water if it has a value of 5.0 to 9.0, but ideally it would fall in the range of 6.0 to 8.0.
How do we measure pH?
Common pH tests, like chemical test kits and pH strips, are simple and inexpensive. However, they come with some issues that could lead to inaccurate results. Both of these methods of testing pH give you results based on a chemical reaction that results in a color change. When your paper or liquid sample changes color, you match it to the color guide provided and get your pH reading. A more accurate means of testing pH is using a pH meter. When choosing a pH tester or meter, there are a numbe...
What istemperature?
Temperature is one of the most common measurements in our everyday life. In the context of water quality, temperature can provide an indication of the living conditions for aquatic plants and animals. Warm temperatures are generally considered beneficial for growth of aquatic populations. However, after a certain point temperature can have the opposite effect, contributing to a decline in the biological diversity in a water body.
Why is measuring temperature important?
Aquatic organisms such as fish and plankton are cold-blooded, so the temperature of water has a direct impact on their body temperature. These organisms have ranges of temperature in which they can survive, or thrive. As the temperature reaches the high limit of its range for an organism, biological activity will be at a peak. This activity will decrease at the bottom of the range. If the temperature exceeds the acceptable range for an organism, the available supply of oxygen may be too low t...
How do we measure temperature?
Many simple thermometers use thermistor technology. The thermistor is a semiconductor device whose resistance varies as a function of temperature. As the temperature rises, the resistance decreases. This resistance measured by the thermistor is then converted to a value displayed on the Celsius or Fahrenheit scale. Thermistor sensors are suitable for a temperature range of -50° to 150° C (-58° to 302° F).
What is conductivity?
Electrical conductivity (EC) measures how well a substance can transmit an electrical current. Small charged particles, called ions, help to carry the electrical charge through a substance. These ions can be positively or negatively charged. The more ions available, the higher the conductivity; fewer ions would result in lower conductivity. EC is typically reported in milliSiemans per centimeter (mS/cm). Total dissolved solids (TDS) is the amount of dissolved substances in solution. This meas...
Why is measuring conductivity important?
Electrical conductivity (EC) is another way to evaluate water quality, since the increased presence of total dissolved solids (TDS), as expressed by EC, may be an indicator of pollutants. EC can be impacted by carbonates from limestone, man-made point source pollutants such as sewage treatment plants, or man-made non-point source pollutants such as septic systems or agricultural runoff. High concentrations of TDS can lower water quality and cause water balance problems for individual organism...
How do we measure conductivity?
The best way to measure conductivity in with the use of an EC meter. Two electrodes with an applied AC voltage are placed in the solution. This creates a current dependent upon the conductive nature of the solution. The meter reads this current and displays in either conductivity (EC) or ppm (TDS).
What is dissolved oxygen?
The concentration of dissolved oxygen (DO) in water is extremely important in nature as well as in man’s environment. In the oceans, lakes, rivers, and other surface water bodies, dissolved oxygen is essential to the growth and development of aquatic life. Without oxygen, the water can become toxic due to the anaerobic decaying of organic matter. In an industrial environment, water must contain at least 2 mg/L of oxygen to protect water pipes from corrosion. However, boiler system water, in m...
Why is dissolved oxygen important?
DO levels can help indicate the relative health of a water body. If DO levels are normal or high, the water is a good environment for a variety of aquatic life to flourish. If DO levels are low, it may indicate the presence of pollutants in the water. Some aquatic life can exist in water with a wide range of DO, but others cannot survive in a low DO environment. DO measurements are expected to have large fluctuations if the water has significant plant life. This is due to the photosynthesis p...
How do we measure Dissolved Oxygen?
Dissolved oxygen concentrations are most often reported in units of milligrams of gas per liter of water, mg/L. (The unit mg/L is equivalent to parts per million = ppm). Measurements are usually taken in water using a DO probe and meter. It is important to measure DO levels at various times of the day, and at various water depths. These measurements will give an overall picture of the DO levels in the water body being investigated. As with all water quality parameters, these levels must be mo...
What isturbidity?
At its simplest form, turbidity is just the cloudiness of water. The cloudiness typically comes from particles that are suspended in the water that we can’t see individually. These particles could be algae, dirt, minerals, proteins, oils, or even bacteria. Turbidity is an optical measurement that indicates the presence of suspended particles. It's measured by shining light through a sample, and quantifying the suspended particle concentration. The more particles that are in a solution, the hi...
How do we measure turbidity?
One way to measure turbidity is using a Secchi disk. A Secchi disk provides an indication of the maximum depth at which plant life can grow by identifying the depth where light no longer penetrates the water. Photosynthesis cannot take place without light, so plants will not grow at depths below the level where the Secchi disk is visible when immersed. Because Secchi disk measurements are based upon the disk being lowered until it disappears, it cannot be used in rivers which are shallow or h...
Turbidity Calibration in the Field
Calibration is simple with the use of commercially available polymer primary standards (AMCO-AEPA-1). These pre-made standards are preferred but standards can be prepared using Formazin according to the EPA analytical Method 180.1. The cuvettes should be free of scratches or cracks and always handle the cuvette by touching only the cap or its top side so as not to dirty it. Any cuvette with visible scratches will be discarded. Calibration Procedure *If formazin standards are used, mix the cuv...
