Drinking Water

  • There are two wells at Heretty cabin. Water in the new well (closer to the cabin) is suitable for drinking. Water in the old well (near the road) has been tested and should be used other purposes, such as washing dishes.
  • The water in Lortikka's new drilled well has too much fluoride (1.9 mg/l, maximum value for domestic water 1.5 mg/l, 17, June 2022). According to the health inspector's assessment, it does not cause health harm if the water is used for a short period of time and occasionally. In addition, the water contains more iron, manganese and color than is recommended for domestic water. These mainly cause odor and taste problems. Use of water at your own discretion. The well is located along Lortikantie, about 40 meters from the rental hut's parking area. It is not marked on the maps yet.
  • Surface water, such as water from lakes, rivers and brooks should be boiled before drinking, because the quality of the water varies in different areas.

Waste Management

  • There are no waste-bins in the area. Measures should be taken in advance to avoid taking unnecessary waste into the area.
  • Small amounts of clean paper and cardboard can be used as kindling in a campfire.
  • Biodegradable waste should be placed in a dry toilet. At Heretty there is a toilet that is emptied with suction. It is not allowed to put leftovers there, because it would cause promlems with waste treatment.
  • There is a recycling point in Heretty behind the stable.
  • Read more about Hiking without Littering.
