Shuvalovo polygon

• Main tasks
• Modeling of the oil pollution migration.
• Modeling of oil pollution of the inter moraine
  aquifer.
• Assessment of the pollution migration to surface
  water objects.
•

Polustrovo polygon

• Protection of the ground water deposits against
  pollutants migration from upper aquifers.
• Modeling of flooding caused by ground water.
• Estimation of chemical changes caused by negative
  load to ground water.
• Development of the recommendations to reduce
  negative impact to ground water in Polustrove
  area.
