Poland has less water resources than other European countries due to variations in water balance. Water balance depends on water income from precipitation, inflows from abroad, and water collected in lakes and rivers, versus water expenditure from evaporation and consumption for industrial, municipal, and agricultural needs. The document identifies areas with excess water like the Karpaty, Sudety, Żuławy, and Mazurskie lake district, as well as areas with water deficits such as Kujawy, Górny Śląsk, and around Łódź. Water pollution sources include natural admixtures and human activities like sewage, runoff from industrial and agricultural areas, and landfill

2. 1. WATER BALANCE
Poland is a country, which has got less water resources than
other european countries. Water resources depends on
water balance. Water income depends on precipitation,
inflow of waters from abroad and water collected in lakes
and rivers. Expenditure depends on evaporation, water
consumption for industrial, municipal needs and surface
and underground outflow.

3. 2. AREAS WITH EXCESS OF WATER
 Karpaty
 Sudety
 Żuławy
 Mazurskie lake
district

4. 3. AREAS WITH DEFICIT OF WATER
 Kujawy
 Górny Śląsk
 area of Łódź

5. 4. WATER POLLUTION
 Natural – derived from admixtures contained in
surface and undrground waters, for example:
salinity, pollution
 Artifical – human activity: surface sewage,
underground runoff, from industrial and
agricultural areas and landfills

6. 5. WATER PURITY CLASSIFICATION
 I class – water is suitable for drinking, using in food
industry, pharmaceutical and for fish farming
 II class – water intended for animal breeding and
bathing water
 III class – water used to industry except food and
pharmaceutical industry and irrigation of
agricultural areas
