Water Analysis

Water is one of the world’s most valuable resources and must be protected in terms of both public health and the environment.

We employ analytic methods to test water to identify contaminants and hazards and determine its fitness for human consumption.

NSF International is accredited for sampling and testing your water. Samples are taken by trained employees and examined in our in-house laboratory.

Drinking Water

Residential water systems  are legally considered water supply systems, which are governed by  the German Drinking Water Ordinance (TrinkwV 2001). Owners and landlords of buildings with these warm water systems carry the responsibility for ensuring that they pose no health hazards for users.

Profit from the knowledge of our experts and reduce your risks with the help of our custom  examination scopes. With these analyses, you can ensure that the water in your residential installation has optimum quality.

Based on out test results, problems in the installation method can be fixed and disinfection and repair measures can be performed and permanently monitored.

Our services include drinking water sampling and analysis in our labs.

Cold Water

For cold water applications, we provide:

  • Sensory and chemical-physical analyses:

Staining, odor, turbidity, pH value, electrical conductivity, ammonium, calcium, chloride, iron, potassium, manganese, magnesium, sodium, nitrate, nitrite, oxidation and acid capacity pH 4.3

  • Bacteriological analysis:

Colony count 22° C, colony count 36° C, Enterococci, E. coli and coliform bacteria

Hot Water

For hot water applications, we provide testing  for Legionella bacteria according to the UBA recommendation and the German Drinking Water Ordinance (TrinkwV 2001*).

If desired, we can also send your test results to the responsible health department.

Our test parameters are based on the requirements of the German Drinking Water Ordinance.*

*In the valid version from 11/01/2011 as well as the third  ordinance for changing the TrinkwV 2001 from 11/18/2015.

Bottled Water & Beverage Quality

Mineral and table water have nutritional-physiological effects based on their respective mineral contents. They originate from well-protected underground water reservoirs and are bottled based on strict quality criteria, which are clearly defined in the Mineral and Table Water Ordinance.

NSF International has developed its own product certification program for bottled water (including water coolers) and beverages. This is the only certification scheme worldwide that has been accredited by ANSI (ANSI-Accredited Product Certification Body - Accreditation #0216) for this food category.

Hundreds of bottlers worldwide, plus national and international industry associations and consumers, trust the NSF evaluation. As a bottler you are entitled to list the NSF mark on your certified product. Consumers and retailers can thereby be certain of the quality of the products.

In addition, we also offer technical consulting from, as you might say, the source to the bottle. Additionally, we conduct training and audits for plant operations or hygiene in beverage operations.

  • The audits include:
    GMP, HACCP, food safety, food defense and employee training

At our laboratory locations in Germany, the U.S., China and Brazil, we offer comprehensive analyses for bottled water.

  • The analyses include:
    Source water, caps and containers and finished product

Our test parameters for mineral and table waters are based on the requirements of the German Mineral and Table Water Ordinance.

Pharmaceutical Water - Water for Pharmaceutical Use

Due to the special role of prepared water in the pharma industry, the quality specifications for this important raw material are particularly high.

Monographs of the European Pharmacopoeia (Ph. Eur.) define the purity criteria for water used in pharmaceutical settings.

  • Purified water (aqua purificata) is meant for the manufacture of medications, which need to be neither sterile nor pyrogen-free.
  • Water used for manufacturing extracts requires high biological quality.
  • Water for injection is important in the manufacture of parenteral drugs.

We analyze pharmaceutical water according to the following methods:

  • Total count of colony-forming units method according to Ph. Eur. 0008 (purified water)
  • Total count of colony-forming units method according to Ph. Eur. 2249 (manufacture of extracts)
  • Total count of colony-forming units method according to Ph. Eur. 0169 (water for injections)
Dental Practices

The requirements for hygiene in dental practices have risen in the last few years. While hand instruments, turbines and hand and angle pieces are routinely disinfected and sterilized, the risk of infection by contaminated water from the cooling system of the dental unit is not always addressed, despite the Robert Koch Institute (RKI) recommending appropriate water testing.

We can test the water in your dental unit and evaluate whether it complies with the target values of the RKI recommendation.

Bacteriological examinations include:

  • Total germ count at 36° C
  • Legionella bacteria

Further examinations include:

  • Total germ count at 22° C
  • E. coli/coliform bacteria
  • Enterococci
  • Pseudomonas aeruginosa
Wastewater

Wastewater that is returned into the water system must be examined and prepared within the framework of the German Wastewater Ordinance (AbwV). This not only applies to wastewater from communal wastewater treatment plants, but also to production and process water that occurs at various industrial processes.

Our services include sampling with portable sampling units and analysis in our institute. We test for:

  • Our services include sampling with portable sampling units and analysis in our institute. We test for:
  • Biological oxygen demand after 5 days
  • Chemical oxygen demand
  • Total phosphor
  • Nitrate and nitrite nitrogen
  • Organically bound carbon (TOC)

Our test parameters are based on the requirements of the German Wastewater Ordinance.
