Drinking Water Testing
Safe drinking water and fresh air are the unavoidable needs of any living being. More than 70% of the human body is composed of water. But unfortunately, only 3% of water across the globe is fresh water and only half of that is available for human consumptions. In developing countries like India, population growth combined with industrial development is hard pressing on water demand resulting in the shrinkage of the water table.
The shrinking water table, bad industrial waste management practices, and improper sanitation are responsible for the deteriorating quality of drinking water. The most essential requirement to ensure good quality drinking water testing availability is, conduct regular testing of drinking water.

Construction Water Testing
Water is one of the vital elements used in construction. As it has a direct impact on the strength of the cement concrete and mortar. Hence for the construction the quality and quantity of water should be optimized. There are various tests to determine its suitability for construction. It is tested under the cl. 5.4 of Indian Standards 456 (2000). It covers the following parameters.
Water for Construction purpose (As per IS: 456 2000):
| Sr no. | Tests & Parameters | Test Method |
|---|---|---|
| 1 | Acidity of water | IS 3025 Part-22 |
| 2 | Alkalinity of Water | IS 3025 Part-23 |
| 3 | Chloride of Water | IS 3025 Part-32 |
| 4 | Inorganic matter of Water | IS 3025 Part-18 |
| 5 | Organic Matter of Water | IS 3025 Part-18 |
| 6 | pH Value | IS 3025 Part-11 |
| 7 | Sulphate | IS 3025 Part-24 |
Swimming Water Testing
The pool water needs to balance to achieve proper water chemistry. A pool that is balance has proper levels of pH, Alkalinity and chlorine. A few basic maintenance steps will make your pool water sparkling clean. Moreover it should be free from harmful microbes like Coliform bacteria. Add safety to your pool sports by getting it tested time to time.
It is tested as per Indian Standards 3328 (1993). It includes the following parameters:
| Sr no. | Tests & Parameters | Test Method |
|---|---|---|
| 1 | pH Value | IS 3025 Part-11 |
| 2 | Total Alkalinity (as CaCO3) | IS 3025 Part-23 |
| 3 | Aluminum (as Al) | IS 3025 Part-31 |

Waste Water Testing.
For Water, we are offering our services for drinking water testing, construction water, waste water testing, groundwater & swimming pool water.
Bacteriological condition:This test helps in determining the contamination by potentially harmful bacteria and other micro-organisms. Short-term gastrointestinal disorders and illnesses such as gastroenteritis, giardiasis, typhoid, dysentery, cholera, and hepatitis have been linked to water contaminated by microorganisms. The micro-organisms which find their way into a water supply can come from a variety of sources including sewage, animal wastes, or dead and decaying animals.
Biochemical Oxygen Demand:This test helps in determining the amount of dissolved oxygen needed by aerobic biological organisms in a body of water to break down organic material present in a given water sample, at a certain temperature over a specific time period. It is not a precise quantitative test, although it is widely used as an indication of the organic quality of water.
Coli forms (total and fecal) Test:This test helps in monitoring the increase or decrease of many pathogenic bacteria or coli forms.
Ground Water Testing
Groundwater testing protects groundwater resources and the environment. Groundwater must be protected from the adverse effects of agricultural and industrial pollution to safeguard the environment, protect sources of drinking water and avoid well water contaminations.
The quality of groundwater can affect not only our health, but also society and the economy. Groundwater contamination can adversely affect property values, the image of a community, economic development, and the overall quality of life we all share. Clean water at reasonable cost is essential and in many parts of the country, groundwater is the only economical water source available. Once groundwater has been contaminated, it is usually very difficult and costly to clean. Even small contamination sites often cost many thousands of dollars to cleanup. The quality of water from private water supplies, such as those from wells at individual homes, is not regulated. It is the responsibility of the well owner to ensure a safe drinking water supply. Although there are a few requirements for water quality testing and monitoring of private wells (i.e., in some areas, testing is required at the time of property transfer), it is recommended that all well owners have their water tested periodically. While "complete" drinking water analyses can be expensive and are generally unnecessary for the private well owner, it is recommended that private water supplies be tested routinely for common contaminants including total coliform bacteria, nitrates, and lead. These contaminants can occur in well water due to agricultural activity, septic system use, household chemical use/ disposal, age of the plumbing or industrial activity. The frequency of water testing and the contaminants to test for dependon factors such as the potential sources of pollution and the type of well.Another consideration is ensuring that the private well complies with proper well construction standards.
