Drinking Water

The current ordinance 2914/2011 published by the Ministry of Health regulates and establishes criteria for the assessment of drinking water quality. We offer to our Customers a full accomplishment of the 2914, and more, all of them under ISO/IEC 17025.

Replacing Ordinance 518/2004, Ordinance 2914 requires monitoring of new classes of agents such as Saxitoxins, Haloacetic acids and Mancozeb, among others.

Considering that this new ordinance requires new compounds and more restrict MRL (Maximum Residue Level) we moved to more sensitive analytical techniques: Tandem UPLC-MS/MS. The use of UPLC-MS/MS brought in a huge improvement on the quality of certain determinations such as Saxitoxins, Carbamates, Acrylamide and Glyphosate/AMPA. Such analyzes do not require pretreatment of samples and still have analytical limits significantly lower than traditional methods.

PFor Mancozeb, a well-known method for decades (generation of carbon disulfide from acid hydrolysis of Mancozeb), has turned to a more sensitive equipment and technique. In such a case after the generation of the CS2 by acid hydrolysis, and low volume Head Space injection, followed by quantification by HRGC-MS or HRGC-FPD.

The drinking water ordinance 2914 is divided in several groups of parameters, that may be ordered separately or in combination. These groups are:

  • VOC
  • SVOC
  • Pesticides (chlorinated, organophosphorus, carbamates...)
  • Polichlorinated Biphenyl (PCBs)
  • Metals
  • Anions by CI
  • Wet chemistry / Potentiometric
  • Microbiology
  • Acrylamide
  • Cyanobacteria
  • Radioactivity
  • Saxitonin
  • Glyphosate / AMPA
