Our laboratory offers a variety of water tests to ensure your residential or industrial water is safe and free of harmful contaminants.

Water potability test

Price: $55.00 Monitoring sustainable water is a proactive measure in maintaining the landscape of water resource management including; reducing contamination risks and improving water quality. A water potability test will reveal any present Coliforms and E.coli bacteria....

Micro biological potability test

Price: $90.00 Specializing in superior quality trace metals analytical services, DCS Controls Lab Services focuses on metals speciation, trace level detection limits, and the analysis of complex matrices. Our lab has extensive capabilities to analyze low-level trace metals in even the most complex matrices....

On-Site Sampling

Price: varies by region Water chemistry analyses are carried out to identify and quantify the chemical components and properties of a certain water sample. This includes pH, major cations and anions, trace elements and isotopes. Water chemistry analysis is used extensively ...


Coliform bacteria, naturally occurring organic and volatile organic compounds, pollution and deteriorating out of date plumbing can deliver drinking water that may pose health risks.

Unfortunately, efforts to treat water can also result in new health threats: Chlorination of drinking water does virtually eliminate most disease or bacterial contamination, but it also creates traces of several toxic by-products in the water such as:

Other chlorinated organic compounds

Government agencies have decided the benefits are worth the risks, but alternatives are available in many instances.

– As per Government of New Brunswick: In order to confirm that well water is clear of bacteria and other contaminants, private wells should be tested twice per year (preferably in spring or fall)
– If you have your own well, you are responsible for making sure that your water is safe to drink. Private wells should be tested biannually for coliform bacteria and have a General Chemistry Analysis to detect contamination problems early.” In addition to biannual tests, you should test the water anytime there is a change in the taste, odor, or appearance of the well water, or if a problem occurs such as a broken well cap or a new contamination source; if family members have recurrent incidents of gastrointestinal illness; if an infant is living in the home; or if you wish to monitor the efficiency and performance of home water treatment equipment.


Organic chemicals are pesticides, solvents, and other chemicals that seep into ground water supplies. Some are known as volatile organic chemicals (VOCs) because they change (they may evaporate, for example). Most are linked with cancer and/or nervous system, liver and kidney disorders. In the organic group, trihalomethanes (THMs) are sometimes created after water has left a treatment plant, when chlorine may react with leaves and other decaying animal and plant matter. A substance that can result from this process is chloroform, a suspected carcinogen.

Inorganic chemicals include dangerous metals such as mercury, lead and arsenic; sodium; nitrates and nitrites; and a variety of natural minerals. Some inorganics are associated with a variety of health problems. Lead is known to cause brain damage and is highly toxic to infants and pregnant women, even in minute doses. It usually comes from lead water pipes, old pipe solder, or lead-based brass fixtures.

Potable water sampling Procedure

Well shock chlorination procedure

The following well water chlorinating procedure should only be considered as a temporary solution for the mitigation of the presence of microbiological growth until the source of the contamination can be identified. It is suggested that prior to commencing the procedure:
