At CIMA (Atlantic Center for Environmental Research, S.L.), we want to show you what we do—both in our offices and beyond.

On this page, you’ll find a series of short videos called "Things We Do at CIMA", which will help explain what we do and how we do it. All to bring you closer to the world of Marine Biology and Oceanography.

«Things We Do at CIMA» #17: Drinking Water Analysis:

As seen in previous videos, some of our services are closely linked to wastewater in general. However, we also handle the drinking water you consume at home, from public fountains, in the hospitality sector, etc.

Periodically, we collect drinking water samples for analysis in our laboratory. All data obtained from these analyses are collected, stored, and interpreted. Any non-compliance with the analyzed parameters (i.e., concentrations exceeding established limits) must be confirmed by retaking a water sample within 24 hours of detection and notifying the health authorities. Non-compliance mandates an investigation into the cause and requires ensuring corrective and preventive measures are applied as soon as possible to protect public health.

The parameters typically monitored at the consumer’s tap include, at minimum: odor, taste, color, turbidity, conductivity, pH, ammonium, coliform bacteria, E. Coli, copper, chromium, nickel, iron, lead, residual free chlorine and residual combined residual chlorineWhen collecting samples, we measure pH, conductivity, and chlorine. The same day, they are transported to the laboratory in sterile bottles and refrigerated insulated containers to prevent degradation. Once in our laboratory, we analyze the remaining parameters: odor, taste, color, turbidity, microbiology, etc.

Water quality is determined by comparing the physical and chemical characteristics of a water sample with water quality guidelines or standards. For drinking water, these standards ensure a safe supply for human consumption, thereby protecting public health. They are based on acceptable toxicity levels for both humans and aquatic organisms.

Drinking water quality is regulated across the EU by Directive 98/83/ECand in Spain through Royal Decree 140/2003.
