2. GROUNDWATER MONITORING IN ROMANIA (1)
I. GROUNDWATER MONITORING NETWORKS
National Hydrogeological Network
a. Objectives:
knowledge of phreatic and depth aquifers structures spatial
development and of their aquifer potential
knowledge groundwater levels regime
knowledge groundwater physical – chemical properties
b. Wells types:
for phreatic aquiferous strata (until 20 –50 m)
for depth aquiferous strata (50 – 400 m)
c. Responsible: it is at the “Romanian Waters” National Administration
orders, by Water Directorates

I. GROUNDWATER MONITORING NETWORKS
Local Monitoring Networks
a. Objectives and wells types
- local enhancing of water quality (pollution) evolution in case of some pollutant objectives (factories, wastelands etc.), by wells for phreatic aquiferous strata
enhancing piezometric levels evolution in areas of some important groundwater catchments, by wells with depth depending on catched aquifer
b. Responsibles: owners of pollutant objectives or groundwater catchments

1. For phreatic aquiferous strata (until 20 – 50 m)
hydrogeological stations types:
Ist order (aim: enhancing of connection between groundwaters and surface waters): transversal alignments of wells (2 – 15) on the main surface water courses, situated at the distance of 15 – 20 km between them (located in floodplains and terraces)
- IInd order (aim: enhancing of groundwaters regime relative to climatic factors): isolated wells (1 – 2) located in interfluve areas of plains, with a density of 1 well/ 20 km2 - 1 well/ 50 km2
achievement period: 1960 – 1972
total number of achieved wells – ca , out of which in observation:
for levels and temperatures – ca
for water quality – ca
measurements programme:
levels and temperatures - at each 3 days
samplings and analyses – twice/ year (at minimum and maximum levels)
analyzed indicators – 22 (general and of pollution – NO3, NO2, NH4 etc.)

location: unknown areas for depth aquifers of strata
achievement period: 1970 – at present
total number of wells: ca. 500
measurements programme:
levels and temperatures – once/month
samplings and analyses – once/ 2 – 3 year
analyzed indicators – 22 (general and of pollution – NO3, NO2, NH4 etc.)

II. HYDROGEOLOGICAL INFORMATIONAL SYSTEM
Data resulted as consequence of monitoring achieved by National
Hydrogeological Network are stored in hydrogeological database of the
“Romanian Waters” National Administration, by National Institute of
Hydrology and Water Management
