About us

The spring rises from a depth of 402 metres. The NTK - 4 hydrogeological well is located in the protected area of the Low Tatras, about 1200 m north of the production hall. NTK - 4 was bored in the village of Dolná Lehota near the primary school building to a depth of 402 m. The documented maximum steady-state yield is 41.0 ls-1; in a depression it is 53 m. The drill has an artesian overflow whose yield varies between 4.12 l.s-1 and 6.91 ls-1. The level of artesian overflow rises to a maximum of +5.70 m above the terrain. The water has a minimum temperature of 10 and a maximum of 10.9 degrees Celsius; the transient hardness is 14.6 - 15.1.

The sample of water from the NTK - 4 well is characterized as a low mineral water, slightly alkaline, with a pH of 7.78. According to the drinking water quality requirements stipulated by Decree of the Ministry of Health of the Slovak Republic No. 151/2004, on requirements for drinking water and the control of drinking water quality, the sample was analysed, and the water was examined in microbiological and physic-chemical indicators from a hygiene point of view. The analysis shows that the water is entirely suitable for drinking purposes and that the quality parameters of groundwater from the NTK - 4 well are very good; the water is also suitable for babies without the need for purification.
