A water quality parameter defining the concentration of dissolved organic and inorganic chemicals in water. After suspended solids are filtered from water and water is evaporated, dissolved solids are the remaining residue. Dissolved solids may include calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride and silica. Total dissolved solid concentrations depend on the geologic material water passes through in the saturated and unsaturated zone, and the quality of the infiltrating water. High total dissolved solids may effect the aesthetic quality of the water, interfere with washing clothes and corroding plumbing fixtures. For aesthetic reasons, a limit of 500 mg dissolved solids/L is typically recommended for potable water supplies.
Dissolved and suspended solids in water; material left behind after a water sample is filtered and evaporated. Rainwater will have TDS less than 10ppm; municipal water systems will have TDS less than 500 ppm.
Concentration of all substances dissolved in water (solids remaining after evaporation of a water sample).
See TDS. Toxic Means that a substance has an adverse physiological effect on human beings or other living organisms if the substance is contacted, ingested or inhaled.
a measure of the concentration of solids dissolved in water
The sum of all the dissolved minerals in the water expressed in milligrams per litre (mg/L).
Total Dissolved Solids (TDS) - A water quality parameter defining the concentration of dissolved organic and inorganic chemicals in water. After suspended solids are filtered from water and water is evaporated, dissolved solids are the remaining residue.
In potable waters, most matter is in the dissolved form and consists mainly of inorganic salts, small amounts of organic matter, and dissolved gases. As waters become polluted, the amount of undissolved and suspended solids increase, and the dissolved fraction is usually not considered an important effluent parameter.
(TDS) - The concentration of dissolved inorganic chemical constituents in water. Measured in mg/L or ppm.
(TDS) is the amount of dissolved matter in the water.
a measurement of the total PPM of all dissolved minerals and compounds. High TDS can lead to water clarity problems, loss of sanitizer effectiveness and other issues. Click here for some ordering information about TDS PockeTesters.
TDS is the sum of all solids dissolved in water. The components that make up TDS vary, but usually include minerals, metals and salts.

An aggregate of carbonates, bicarbonates, chlorides, sulfates, phosphates, nitrates, etc., of calcium, magnesium, manganese, sodium, potassium, and other cations which form salts. High TDS concentrations exert varying degrees of osmotic pressures and often become lethal to the biological inhabitants of an aquatic environment. The common and synonymously used term for TDS is "salt".
The sum of all inorganic and organic particulate; TDS is an indicator test usually reserved for wastewater analysis, but is also a measure of the mineral content of bottled water and groundwater.
Compare? The quantity of dissolved material in a given volume of water.
Total salt and calcium carbonate concentration in a sample of water. The state recommended Maximum Contaminant Level (MCL) drinking water standard for total dissolved solids is 500 ppm. The upper MCL is 1,000 ppm, and the short-term permitted level is 1,500 ppm.
All material that passes the standard glass river filter; now called total filterable residue. Term is used to reflect salinity.
The amount of dissolved materials in water including chemicals added as well as minerals naturally found in water. Maximum amount in pools is 2500 and in spas is 1500 over the starting TDS. To lower high levels water must be drained and replaced.
A measure of the total amount of dissolved matter in water, such as calcium, magnesium, carbonates, bicarbonates, metallic compounds, etc.
(TDS) - (3) salt - an aggregate of carbonates, bicarbonates, chlorides, sulfates, and nitrates of calcium, magnesium, manganese, sodium, potassium, and other cations that form salts. High TDS solutions can change the chemical nature of water, exert varying degrees of osmotic pressure, and often become lethal to aquatic life.
The total amount of solid material dissolved in one liter of water.
The weight per unit volume of filtered water. The liquid passing the filter are evaporated to dryness. The filter pore diameter and evaporation temperature are frequently specified.
The total inorganic and organic materials dissolved in water. The total dissolved solids in water can be determined after water is filtered through a 0.45 µm filter and evaporated to dryness at 103°C to 105°C, or it can be estimated from concentrations of major ions (calculated).
All material that passes a filter of a specified size.
The amount of dissolved solids, usually fertilizer salts, that are measured in water in parts per million.
The amount of dissolved constituents present in water or wastewater, usually expressed in milligrams per liter and analyzed as filterable residue, as determined using approved methods.
The concentration of dissolved solids in water. TDS is measured on a sample of water that has passed through a very fine mesh filter to remove suspended solids. The water passing through the filter is evaporated and the residue represents the dissolved solids.
The dissolved solids found in water that consist of organic and inorganic matter.
A measure of everything that has ever dissolved in the water; all the matter that is in solution. High TDS levels can oversaturate your water, causing all sorts of reactions.
(TDS) - the measure of all of the dissolved matter in the water. TDS over 1500 ppm may interfere with the pool sanitizer's ability to control bacteria & algae.
The weight of solids per unit volume of water which are in true solution; usually determined by the evaporation of a measured volume of filtered water and determination of the residue weight. Total Dissolved Solids is a measurement of any minerals or salts in the water. Bicarbonate, Chloride, Sulfate, Calcium, Magnesium, Sodium are the major components of dissolved solids in water. High amounts of these salts provide the major cause of water taste problems. High TDS can cause the water to appear inappropriate to drink, and spotting of glassware, fixtures, or painted surfaces such as automobiles. Also high dissolved solids can diminish the life of home appliances. The EPA has set a maximum contaminant level of 500 ppm.
A measure of the total amount of dissolved matter in water, e.g. calcium, magnesium, carbonates, bicarbonates, metallic compounds, etc.
Total amount of dissolved material, organic or inorganic, contained in a sample of water.
Total Dissolved solids are not visible to the naked eye. However, when water is frozen, ice cubes may look cloudy.
The total weight of all solids (organic and inorganic) dissolved in water, in parts per million (ppm) or milligrams per litre (mg/L) of water.
Total Dissolved Solids - Also called TDS - A measure of the total amount of dissolved material in the water. It is comprised of the spent or carrier chemicals added every time chemicals are added, as well as the hardness, alkalinity, chlorides, sodium, magnesium, calcium, etc. Maximum amount in pools is 2500 ppm. Maximum in spas is 1500 over starting TDS. The only way to effectively lower TDS is to drain part or all of the water and replace it.

Dry weight of dissolved material, organic and inorganic, contained in water that will not be removed by a 0.45 micron filter; usually described in units of mg/1.
A measure of all solids dissolved in the water. It can cause dull, flat, salty water if too high.
TDS. The total dissolved mineral matter in water (e.g., formation water). Usually measured in mg/litre and often reported in parts per million, sometimes in grains per gallon.
The total weight of the solids that are dissolved in the water, give in ppm per unit volume of water. TDS is determined by filtering a given volume of water (usually through a 0.45 micron filter), evaporating it at a defined temperature (usually 103-105 degrees Celsius), and then weighing the residue. Note: A test measuring the electrical conductivity of the water provides only an estimate of the TDS present, as conductivity is not precisely proportional to the weight of an ion and nonconductive substances cannot be measured by electrical tests.
Total dissolved solids is an expression for the combined content of all inorganic and organic substances contained in a liquid which are present in a molecular, ionized or micro-granular (colloidal sol) suspended form. Generally the operational definition is that the solids (often abbreviated TDS) must be small enough to survive filtration through a sieve size of two micrometres. Total dissolved solids are normally only discussed for freshwater systems, since salinity comprises some of the ions constituting the definition of TDS.
