Introduction. The current study represents the third stage of the research project
called ‘Promoting innovative, lasting technologies in the treatment of water for human
consumption.’
Materials and method. The actions necessary for the completion of the
epidemiological survey took place during this stage. The case study consisted of the physicalchemical
and microbiological analysis of the drinking water at the consumer end in the
county of Timisoara . The connection between the prevalence of hydrical diseases in the
population group surveyed and the microbiological, chemical and physical quality of the
water distributed through the centralised water systems was determined, in particular that
distributed by the water plants U1, U2-4, U5 and the local public drilling methods. Results.
Due to the lack of micro organisms in the drinking water, a clear connection between
morbidity by gastro-intestinal diseases and the quality of the water could not be established.
As far as the connection between general health and the physical-chemical quality of the
water is concerned, a change in health indicators was observed. The prevalence of
cardiovascular diseases in people who mainly consume surface water (63,1%) was higher
than in people who mainly consume deep water (36%). High concentrations of chlorine,
ammonia, iron and manganese, as well as increased water temperatures led to organoleptical
changes. Fluorine concentrations lower than 0,5 mg/l (concentrations found in drinking
water ranged between 0,2-0,42 mg/l) were connected to the prevalence of cavities in 100% of
the cases. Conclusions. Failing to include organoleptical indicators as part of the sanitary
norms has had implications on the consumers’ psyche; not taking pleasure in the
consumption of water does not quench the feeling of thirst. To rule out health risks to the
consumers, an ongoing monitoring of the water is recommended at the water plant 1, where
trihalomethanes have been temporarily detected, though they are at present within legally
acceptable levels. Assessing health risks still proves to have minimum efficiency due to
insufficient information, especially in the case of multiple exposure.

INTRODUCERE
Studiul prezent reprezintă etapa III
„Identificarea soluţiilor tehnologice optime
pentru reabilitarea/modernizarea staţiilor de
tratare neconforme- cercetare
fundamentală”, a proiectului de cercetare de
excelenţă „Promovarea tehnologiilor
inovative şi durabile pentru tratarea apei
destinate consumului uman”, al cărui
beneficiar este Ministerul Educaţiei şi
Cercetării, iar contractorul principal
Institutul Naţional de Cercetare-Dezvoltare
pentru Ecologie Industrială – INCD
ECOIND Bucureşti.
Proiectul s-a desfăşurat în cadrul Institutului
de Sănătate Publică Timişoara – Secţia
Igiena Mediului Alimentaţiei şi
Colectivităţilor – IMAC (Compartimentul
IMAC şi Laboratorul de Evaluarea Riscului
Comunitar), în calitate de partener la
proiect.
Obiectivul general al proiectului a fost:
protejarea sănătăţii publice prin consumul
unei ape potabile corespunzătoare calitativ.
Tema de lucru a fost evaluarea relaţiei dintre
calitatea apei potabile şi starea de sănătate a
populaţiei din municipiul Timişoara.
Obiectivele specifice ale proiectului au fost:
• realizarea anchetei epidemiologice privind
evaluarea stării de sănătate în relaţie cu
factorul hidric, municipiul Timişoara
• stabilirea evoluţiei calităţii apei la sursă, pe
fluxul de tratare, şi evaluarea gradului de
conformare al apei potabile cu cerinţele
legislaţiei româneşti şi europene în vigoare.
