What do you see on a water analysis report?
This article outlines some of the major parameters you may see on the analysis and assists you in understanding the numbers on a water test report. Whether your water causes illness, stains on plumbing, scaly deposits, or a bad taste, a water analysis identifies the problem and enables you to make knowledgeable decisions about water treatment.
What are the units used in a water test report?
Another unit found on some test reports is that used to measure radon--picocuries per liter. Some values like pH, hardness, conductance, and turbidity are reported in units specific to the test. In addition to the test results, a lab may make notes on any contaminants that exceeded the PA DEP drinking water standards.
What is included in the results of a drinking water test?
Some values like pH, hardness, conductance, and turbidity are reported in units specific to the test. In addition to the test results, a lab may make notes on any contaminants that exceeded the PA DEP drinking water standards. For example, in Figure 1 the lab noted that total coliform bacteria and iron both exceeded the standards.
What does hard water mean on a plumbing report?
Hardness is one contaminant you will also commonly see on the report. Hard water is a purely aesthetic problem that causes soap and scaly deposits in plumbing and decreased cleaning action of soaps and detergents. Hard water can also cause scale buildup in hot water heaters and reduce their effective lifetime.
What are the 3 parts of the water treatment process?
There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment.

What does turbidity indicate?
Turbidity is the measure of relative clarity of a liquid. It is an optical characteristic of water and is a measurement of the amount of light that is scattered by material in the water when a light is shined through the water sample. The higher the intensity of scattered light, the higher the turbidity.
What is screening and straining?
Screening and straining devices trap trash and coarse debris using smaller apertures such as grates or screens.
What is flocculation and coagulation?
Coagulation and flocculation are two separate processes, used in succession, to overcome the forces stabilising the suspended particles. While coagulation neutralises the charges on the particles, flocculation enables them to bind together, making them bigger, so that they can be more easily separated from the liquid.
What is aeration in water treatment?
Aeration is an in-line point-of-entry process that reduces the concentration of volatile organic compounds. Aeration also removes dissolved gases such as hydrogen sulfide, methane, and radon. Aeration oxidizes dissolved iron, although the resulting iron particles can foul the packing material in some aeration devices.
What is screening and straining in water treatment?
Screens or sieves are great for straining larger particles out of water and are a simple, but flexible technology for diverse configurations. These work well applied at (inlet of) central treatment facilities, but simple use makes it suitable for decentralized or rural applications.
How do you test the purity of water?
The purity of water can be tested by evaporating it (to dryness) on an evaporating dish or by measuring its boiling point.
What is flocculation in water treatment?
Flocculation is a water treatment process where solids form larger clusters, or flocs, to be removed from water. This process can happen spontaneously, or with the help of chemical agents. It is a common method of stormwater treatment, wastewater treatment, and in the purification of drinking water.
What is a CCR report?
Every community water supplier must provide an annual report, sometimes called a Consumer Confidence Report, or “CCR,” to its customers. The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water.
How does a water treatment unit work?
Even though EPA regulates and sets standards for public drinking water, many Americans use a home water treatment unit to: 1 Remove specific contaminants 2 Take extra precautions because a household member has a compromised immune system 3 Improve the taste of drinking water
What are the steps of water treatment?
Today, the most common steps in water treatment used by community water systems (mainly surface water treatment) include: Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water.
What is a water softener?
Water Softeners. A water softener is a device that reduces the hardness of the water. A water softener typically uses sodium or potassium ions to replace calcium and magnesium ions, the ions that create “hardness.”. Distillation Systems.
What is the most common type of water treatment system?
The most common types of household water treatment systems consist of: Filtration Systems. A water filter is a device which removes impurities from water by means of a physical barrier, chemical, and/or biological process. Water Softeners. A water softener is a device that reduces the hardness of the water.
Why do people use water treatment units?
Even though EPA regulates and sets standards for public drinking water, many Americans use a home water treatment unit to: Remove specific contaminants. Take extra precautions because a household member has a compromised immune system. Improve the taste of drinking water.
Is drinking water safe?
Drinking water supplies in the United States are among the safest in the world. However, even in the U.S., drinking water sources can become contaminated, causing sickness and disease from waterborne germs, such as Cryptosporidium, E. coli, Hepatitis A, Giardia intestinalis, and other pathogens.
What is the water industry's emergency preparedness?
In fact, a 2019 survey found that emergency preparedness is one of the top 10 issues facing the water industry. The America’s Water Infrastructure Act of 2018 required community water systems serving more than 3,300 people to develop or update risk assessments and emergency response plans (ERPs).
How many people rely on water?
About 13 million households in the nation rely on water from private wells. Our nation’s drinking water infrastructure is composed of 2.2 million miles of pipe, most of which is underground and unseen by the millions of consumers who rely on it every day; unfortunately, this often means that water infrastructure is out of sight and thus out of mind.
What is the EPA's water regulation?
Since 1974, the EPA has regulated the nation’s public drinking water supply through the Safe Drinking Water Act (SDWA). The EPA sets national health-based standards and determines the enforceable maximum levels for contaminants in drinking water. All water suppliers are required to notify consumers upon learning of a serious water quality problem, and states and the EPA are required to prepare annual summary reports of water system compliance that must be made available to the public. In 2019, the number of public water systems with health-based violations was 15% lower than in 2017, and public water systems that were returned to SDWA compliance increased nearly 7% compared to 2017.
How many miles of water pipes will be replaced by drinking water in 2020?
It is estimated that more than 12,000 miles of water pipes were planned to be replaced by drinking water utilities across the country in 2020. Drinking water systems currently lose at least 6 billion gallons of water, or 9,091 Olympic-size swimming pools, every day.
How many gallons of water are lost in a day?
There is a water main break every two minutes and an estimated 6 billion gallons of treated water lost each day in the U.S. enough to fill over 9,000 swimming pools. However, there are signs of progress as federal financing programs expand and water utilities raise rates to reinvest in their networks.
How much will the water infrastructure gap grow in 2029?
Economic Recovery” found that the annual drinking water and wastewater investment gap will grow to $434 billion by 2029.
Is there a federal requirement for water systems?
Some states have asset management requirements for drinking water systems, but there is no federal requirement. Other states give priority for DWSRF loans to water projects that have an asset management plan or provide funding for asset management plan development, training, and technical assistance.
What are the indicators of water quality?
General Water Quality Indicators are parameters used to indicate the presence of harmful contaminants. Testing for indicators can eliminate costly tests for specific contaminants. Generally, if the indicator is present, the supply may contain the contaminant as well. For example, turbidity or the lack of clarity in a water sample usually indicates that bacteria may be present. The pH value is also considered a general water quality indicator. High or low pHs can indicate how corrosive water is. Corrosive water may further indicate that metals like lead or copper are being dissolved in the water as it passes through distribution pipes. Table 2 shows some of the common general indicators.
What is hard water?
Hard water is a purely aesthetic problem that causes soap and scaly deposits in plumbing and decreased cleaning action of soaps and detergents. Hard water can also cause scale buildup in hot water heaters and reduce their effective lifetime.
What is the unit used to measure contaminant level in water?
An important feature of the report is the units used to measure the contaminant level in your water. Milligrams per liter (mg/l) of water are used for substances like metals and nitrates. A milligram per liter is also equal to one part per million (ppm)--that is one part contaminant to one million parts water.
Why is water analysis important?
Whether your water causes illness, stains on plumbing, scaly deposits, or a bad taste, a water analysis identifies the problem and enables you to make knowledgeable decisions about water treatment.
