Occurrence:
- Most phosphates enter waterways through plants and rocks.
- They can also enter waterways through manmade sources, which include human sewage discharges, agricultural fertilizer runoff, manufacturing and detergents.
How do phosphates affect water quality?
Phosphates are chemicals containing the element phosphorous, and they affect water quality by causing excessive growth of algae. About 3 1/2 pounds of phosphates per person enter the environment in the United States annually from farms, yards, waste water and factory waste.
What are the effects of phosphate in water?
The Effects of Phosphate Pollution
- Algal Bloom Blankets. When phosphorus and nitrogen meet in freshwater ecosystems, algal blooms are likely to form. ...
- Water Nutrient Increase. Too many nutrients might not seem harmful, but an excess of anything can cause trouble in your lake or pond.
- Damaged Water Quality. Oxygen levels take a dive as a result of too much phosphorus. ...
Why is phosphate used in drinking water?
Water utilities treat drinking water by adding phosphate to prevent metal dissolution from water pipe work systems and particularly lead poisoning. Phosphate can be a limiting nutrient for microbial biofilms in DWDS, yet its effects on these microbial consortia are not well understood.
What foods have phosphates?

What are sources of phosphates?
A variety of foods naturally contain phosphorus, and the richest sources are dairy, red meat, poultry, seafood, legumes, and nuts. Phosphorus from these foods is called organic phosphorus. It is absorbed more efficiently from animal foods than plant foods.
What causes high levels of phosphate in water?
High phosphate levels can come from man-made sources such as septic systems, fertilizer runoff and improperly treated waste-water. The phosphates enter the water as the result of surface run-off and bank erosion. 2. Many detergents contained phosphates before manufacturers developed phosphate-free alternatives.
Is phosphate naturally in water?
Natural waters have a phosphorus concentration of approximately 0.02 parts per million (ppm) which is a limiting factor for plant growth. On the other hand, large concentrations of this nutrient can accelerate plant growth. Phosphates enter waterways through manmade sources also.
What does phosphate mean in water?
Phosphates are chemical compounds that contain phosphorous. Phosphorous is a key nutrient that both plants and animals use for growth and development. Whilst phosphate is essential for plant and animal life, too much of it can cause a form of water pollution known as eutrophication.
What removes phosphate from water?
Chemical treatment for phosphorus removal involves the addition of metal salts to react with soluble phosphate to form solid precipitates that are removed by solids separation processes including clarification and filtration.
How do you reduce phosphates in water?
Keeping organic materials, such as leaves and yard waste, out of your pool prevents phosphate buildup. As organic material breaks down, it releases phosphates into the water. Another option is to prevent algae buildup as much as possible.
Does tap water have phosphate?
The water running through the system came from the local drinking water supply, this water is treated with chlorine and has an average phosphate concentration of 1 mg/L.
Is phosphate bad in drinking water?
Phosphates are safe to ingest at reasonable levels. They are important complexed components of all plant and animal based foods that we consume because they are components of all cells.
Is phosphate good in drinking water?
Moderate drinking seems to be good for the heart and circulatory system, and probably protects against type 2 diabetes and gallstones. Heavy drinking is a major cause of preventable death in most countries.
What happens if there is too much phosphate in drinking water?
Phosphates are not toxic to people or animals unless they are present in very high levels, i.e., > 1000 mg/L. Digestive problems could occur from extremely high levels of phosphate, leading to Hyperphosphatemia.
What conditions cause high phosphate?
If your test shows you have high phosphate/phosphorus levels, it may mean you have: Kidney disease. Hypoparathyroidism, a condition in which your parathyroid gland doesn't make enough parathyroid hormone. Too much vitamin D in your body.
What happens when phosphorus is too high in water?
Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality, food resources and habitats, and decrease the oxygen that fish and other aquatic life need to survive.
Is it safe to drinking water with phosphate?
According to the FDA, phosphates are characterized as a food additive and “generally recognized as safe.” But given the fact that other government regulatory organizations, like the EPA, find there to be a safe limit of lead and other heavy metals in drinking water, “generally recognized as safe” isn't as comforting as ...
What is Phosphorus?
Phosphorus, one of the five main elements of living organisms, is essential to orgnanic life . Although elemental phosphorus rarely exists naturally, it does occur in several other forms, mainly as phosphates. Orthophosphate (PO43-) is the soluble form of phosphate and is a naturally occuring ion within water. This form is readily available for uptake by photosynthetic organisms but is most commonly found in low concentrations in natural waterways. Other typed of phosphate are bound in living or decaying organic material or within sediments and soils.
What is YSI Alyza PO4?

For maximum accuracy, the analyzer features automatic 2-point calibration and precise temperature control at each measurement stage.
How to remove phosphorus from water?
There are two primary mechanisms for removing phosphorus from wastewater, chemical removal, adn biological removal. Chemical phosphorus removal requires the addition of metal salt to the water. Soluble phosphorus (orthophosphate) reacts with the metal salt to form a solid precipitate and then removed from the water within clarifier or filtration processes. Alum (aluminum sulfate) or ferric (ferric chloride) are common chemicals dosed in wastewater to achieve this effect. A common method is to add alum or ferric to the process near the end of the aeration basins within an activated sludge plant, giving it ample time to react with the soluble phosphorus before entering the clarifier. The precipitated phosphorus is then removed by sludge wasting. Chemical dosing can be automated using an orthophosphate analyzer by proving a control setpoint and a feedback orthophosphate signal to the dosing pump.
Why use orthophosphate analyzer?
Orthophosphate analyzers are used to monitor phosphate levels throughout the distribution system and automate phosphate dosing. Due to eutrophication concerns in freshwater ecosystems, orthophosphate analyzers have been adapted for the environmental monitoring of lakes and rivers.
How does biological phosphorus removal work?
Biological phosphorus removal involves cultivating bacteria (phosphorus accumulating organisms, or PAOs) that take up phosphorus within their bodies. By providing the right environment, these PAOs will take up more phosphorus than usual to maximize removal.
How to monitor phosphorus removal in wastewater treatment?
Phosphorus removal in wastewater treatment can be monitored and controlled by measuring orthophosphate.
What are the sources of phosphorus in aquatic ecosystems?
There are several sources of phosphorus in our aquatic ecosystems. Non-point sources, such as fertilizer runoff, are the most significant contributor. However, municipal and industrial wastewater facilities (point sources) are another significant contributor of phosphorus. These facilities remove organics and solids from wastewater but, more recently, are required to remove nutrients like phosphorus and nitrogen. Phosphorus removal has become an essential priority for facilities discharging to freshwater systems or other at-risk environments. In the US, effluent limits for total phosphorus (TP) are commonly below 1 mg P/L, with critical regions implementing "ultra-low" limits below 0.1 mg P/L.
How is phosphorus transferred to runoff water?
A small amount of dissolved phosphorus exists naturally in soils. This may be transferred to runoff water by exchanges with the top layer of the soil. Recently applied fertilizer or manure still on the soil surface can be a particularly large source of dissolved phosphorus if runoff takes places.
Why is phosphorus important to plants?
Phosphorus is the plant nutrient most often responsible for impairment of surface water. It is essential for healthy, productive crops and most agronomic systems call for application of commercial fertilizer or animal manure to correct so il phosphorus deficiencies . For agronomic, economic and environmental reasons, application of phosphorus is not recommended, however, where soil tests show phosphorus reserves are adequate for the intended crop.
What is the condition of nutrient enrichment and high plant productivity called?
This condition of nutrient enrichment and high plant productivity is referred to as eutrophication.
What is phosphorus associated with?
Particulate phosphorus may be associated with soil particles and minerals containing aluminum, iron or calcium or with organic matter, like plant or animal materials. Particulate phosphorus moves primarily by soil erosion or wash off from the land surface.
What are the effects of eutrophication?
Another undesirable effect of eutrophication is the growth of blue-green algae. These algae gain a competitive advantage and tend to dominate the algal community where phosphorus is in excess. They are a particular concern because they release odiferous and even toxic compounds. Their presence at high concentration (called bloom conditions) generally results in odor and taste problems in drinking water and allergic and even toxic effects for those who come in contact with them. Blue-green algae blooms in Oklahoma ponds have caused cattle death.
Where does phosphorus come from?
Phosphorus comes from both point and nonpoint sources. Point sources include municipal waste treatment plants, industrial discharge, large confined livestock operations and urban stormwater. These sources are regulated by federal and state laws. They are generally required to have environmental controls, such as waste handling, treatment systems and nutrient management plans.
Why is it difficult to improve water quality in a lake?
Improving water quality in a lake impaired by excessive phosphorus is difficult because phosphorus accumulates in the sediments and biota in addition to the water body. Consequently, it may take years after phosphorus sources have been reduced or eliminated for conditions to improve. Therefore, it is important to take preventive steps to limit phosphorus movement into surface waters.
Why is phosphorus added to water?
It is added to effectively prevent any lead entering the water supply, which can come from the corrosion of old piping. Lead is a toxic metal and adding phosphate has proven to be very successful in reducing human exposure to it. But just what is the fate of this phosphate?
How much water does the UK lose to leakage?
Latest statistics show that the biggest UK water utilities lose around 25 per cent of drinking water to leakage – or around 40 litres per customer per day. Based on the amount of phosphate which is presently added to tap water, this is equivalent to around 1200 tonnes of phosphorus entering the environment every year.
Is phosphate harmful to humans?
Although phosphate is not harmful to humans, anthropogenic, or man-made, inputs of phosphorus are well known to have a significant impact on ecosystems, and can damage the health of rivers and lakes (known as eutrophication). What ultimately happens to phosphate after leakage is currently unknown. However, as the UK water industry focuses on lowering the amount of leakage that is acceptable, this may also cut down any negative effects on the environment of phosphate leaking from drinking water.
Is phosphorus in water a problem?
Whilst the addition of phosphorus to drinking water is beneficial to our health by reducing our exposure to lead from old pipes, its leakage can have a very damaging impact on the environment by affecting the ecology of streams, rivers and estuaries.”
Who is Ben Surridge?
Dr Ben Surridge, a lecturer who leads research with phosphate isotope analysis at Lancaster University, said: “Lancaster Environment Centre and the BGS are at the forefront of research that is developing this isotopic label for phosphate. The label provides new opportunities to understand the sources and the fate of phosphorus in the environment. These are important challenges and our work with phosphate in drinking water is one example of the highly novel research we are undertaking in this area.”

Why do phosphates pool in water?
Phosphates can pool in your lake, pond, or other body of water as a result of man-made and naturally occurring incidents. Here are the top factors that lead to phosphate pollution.
What happens when rain falls?
Over time, rainfall erodes rocks and similar compositions found in soul. As rain continues to fall and release sediments from erosion, it also causes phosphate runoff into adjacent waters.
What happens when you treat waste?
Human waste carries high levels of phosphates. When treatment plants and other industrial areas produce or try to treat waste, the remaining nutrients may easily leach into surrounding soil and, eventually, water.
Why does oxygen take a dive?
Oxygen levels take a dive as a result of too much phosphorus. In bodies of water with an incredibly dense population of plants, or eutrophic water, animals and even other plants suffer from the low supply of oxygen.
What Are Phosphates?
We’re so glad you asked! The quick answer is they’re chemical compounds that contain phosphorus. If you remember any of your high school chemistry, you’ll know this is a naturally occurring, non-metal element. In addition to phosphorus, phosphates contain oxygen and sometimes hydrogen, as well as other chemicals.
Why does algae store phosphates?
Algae stores phosphates to sustain itself. When it dies, algae sinks to the bottom of whatever body of water it’s in, and the phosphate it was retaining is released back into the water to serve as food for remaining algae, and for new growth.
How much phosphate can produce algae?
Just one pound of phosphate can produce 700 pounds of algae. All the phosphate being pumped into lakes, rivers, and streams from wastewater plants created huge algae blooms. By the late 1960s, thousands of lakes and rivers—including the Great Lakes and the Potomac River and its estuary—had been affected.
What is castile soap made of?
Soaps and detergents used to be made from natural ingredients such as wood ashes and animal fat, or tallow. And you’ve probably heard of Castile soap and know that it’s a vegetable-based cleanser, but you may not know why it’s called that.
What is the best sequestrant for pool?
The most effective metal sequestrants are phospha te-based. If you have metal in your pool, and you use a phosphate-based sequestrant, and then use a phosphate remover, you’re negating the effects of the sequestrant.
What is the active ingredient in phosphate remover?
Some of the most popular phosphate removers have an active ingredient—the substance that actually works on the phosphates—called lanthanum. It’s a soft metal element that’s classified as a rare earth element despite the fact that it’s almost three times more abundant than lead.
Why do mammals die in lakes?
In addition, the more algae in a source of drinking water, the less clean water there is to drink, so the mammals that depend on a lake or stream will also either begin to die, or they’ll be forced to move in order to find water.
