Water Testing

Almost, any natural water that is drinkable can be used as mixing water for making concrete. However, some waters that do not fit drinking criteria may be suitable for use in concrete.

TQP can test water physically and chemically to check its compliance with the criteria mentioned in ASTM C94 and AASHTO T26.

TQP can also test other water parameters indicating its quality or having impact on the environment; such parameters are BOD, COD, heavy metals (mercury, chromium, Zinc, Boron, etc), Turbidity level, Sulfides, Sulfites, etc.

Waste water is also tested for all parameters needed for studying compliance with national and international regulations.


Water Tests

Water Test Method Description Date
Aluminum in water Standard test methods for water Aluminum is the third most common element in the earth’s crust, which accounts for its wide appearance in many water supplies. Properly treated drinking water should have an aluminum concentration below 0.2 mg/L. Jan. 2017
Ammonium in water Standard test methods for water Ammonia in water is an indicator of possible bacterial, sewage and animal waste pollution. The limit of Ammonia according to the WHO guidelines of drinking water quality is <1.5 ppm. Jan. 2017
Arsenic in water ISO 11885 Arsenic in drinking-water is a significant cause of health effects in some areas, and arsenic is considered to be a high-priority substance for screening in drinking-water sources. The limit of arsenic according to the WHO guidelines of drinking water quality is < 0.01 ppm. Jan. 2017
Bacteriological Analysis of Water Standard test methods for water The most common and widespread danger associated with drinking water is contamination, either directly or indirectly, by sewage, other wastes or human and animal excrement. The water sample is tested for the presence of Total Coliformes, Fecal Coliformes, Fecal Streptocoques and Pseudomonas aeruginosa. The water sample conforms to the National and International norms concerning bacteria in drinking water when there is absence of any of the above mentioned bacteria in drinking water. Jan. 2017
Barium content in Water ASTM D3651 Although barium is relatively abundant in nature, usually only trace amounts are found in water. Barium concentrations average about 0.05 mg/L in potable waters, but may range as high as 0.9 mg/L in some natural waters. More than 1 mg/L of barium implies that the water is not suitable for drinking and is polluted by industrial wastes. The limit of barium according to the WHO guidelines of drinking water quality is 0.7 ppm. Jan. 2017
Biological Oxygen Demand of water (BOD) Standard test methods for water Biochemical oxygen demand represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions at a specified temperature. Generally, when BOD levels are high, there is a decline in DO levels. This is because the demand for oxygen by the bacteria is high and they are taking that oxygen from the oxygen dissolved in the water. If there is no organic waste present in the water, there won't be as many bacteria present to decompose it and thus the BOD will tend to be lower and the DO level will tend to be higher. There is no guidelines for the limits of BOD in the WHO guidelines of drinking water quality. Feb. 2017
Boron content of water Standard test methods for water Small amounts of boron are necessary for plant growth but large amounts can be toxic. In humans, boron aids in the uptake of calcium and the production of strong bones. An excess of boron can affect the central nervous system resulting in a syndrome known as borism. Some natural waters may contain small amounts of boron. Large concentrations may be due to industrial effluent entering waterways. The limit of boron according to the WHO guidelines of drinking water quality is 0.3 ppm. Feb. 2017
Cadmium in water Standard test methods for water The solubility of cadmium in natural water is proportional to the hardness or alkalinity of the water. Cadmium is not an essential nutrient for plants and animals. It is extremely toxic and can accumulate in the kidneys and liver. The limit of cadmium according to the WHO guidelines of drinking water quality is 0.003 ppm. Feb. 2017
Calcium in water ASTM D511 Calcium occurs in water naturally. Seawater contains approximately 400 ppm calcium. Calcium is largely responsible for water hardness, and may negatively influence toxicity of other compounds. The limit of calcium as calcium carbonate according to the WHO guidelines of drinking water quality is less than 300 ppm. Feb. 2017
Chemical analysis of water for use in concrete AASHTO-T26 Water to be used in concrete mixing shall satisfy standard requirements mentioned in AASHTO T26 concerning the following parameters: pH, Chloride, Sulfate, Total dissolved salts and total alkalies. March 2017
Chemical analysis of water for use in irrigation Standard test methods for water "Water to be used for irrigation shall satisfy international standard requirements concerning some constituents like chloride, sulfate, nitrate, heavy metals, etc. Please note: “This test is not priced, please contact us for more details” March 2017
Chemical Oxygen Demand of water (COD) Standard test methods for water The chemical oxygen demand test procedure is based on the chemical decomposition of organic and inorganic contaminants, dissolved or suspended in water.COD is an essential criterion in evaluating the pollution level in water. The higher the COD, the higher the amount of pollution in the test sample. March 2017
Chlorides content of water ASTM D512 Chloride in drinking-water originates from natural sources, sewage and industrial effluents, urban runoff containing de-icing salt and saline intrusion. It is highly detrimental to high-pressure boiler systems and to stainless steel, so monitoring is essential for prevention of damage. Excessive chloride concentrations increase rates of corrosion of metals. The limit of chloride according to the WHO guidelines of drinking water quality is 250 ppm. March 2017
Chromium (VI) in water Standard test methods for water Chromium is considered to be a toxic chemical and, if present in an amount of over 0.5 ppm, is evidence of contamination from untreated or incompletely treated industrial waste. The limit of chromium according to the WHO guidelines of drinking water quality is 0.05 ppm. March 2017
Color of water Standard test methods for Water Color in water may be attributed to humus, peat, plankton, vegetation, and natural metallic ions, such as iron and manganese, or industrial waste. Color is removed to make water suitable for domestic and industrial use. The limit for color of water according to the WHO guidelines of drinking water quality is 15 TCU. March 2017
Conductivity of water ASTM D1125 TQP uses chemical and physical testing, either destructive or non-destructive, to verify the quality of your product. March 2017
Copper in water Standard test methods for water Copper is both an essential nutrient and a drinking-water contaminant. Copper concentrations in drinking-water vary widely, with the primary source most often being the corrosion of interior copper plumbing. The limit for copper of water according to the WHO guidelines of drinking water quality is <2 ppm. March 2017
