Undersökning av kalciumkarbonatförekomsten i Vombfältet
Author
Summary, in English
In a study of the neutralization capacity and limestone content the artificial recharge area of the Sydvatten waterworks Vombverket in Vomb, Skåne, five samples from different locations in the area was collected, sieved and acidified with hydrochloric acid. The neutralization capacity measured as calcium carbonate content was
found to vary in the different sandy soil samples but was generally high (about 2–14 % by weight). The total mass of calcium carbonate in the infiltration area was determined taking into account the volume and density, i.e. possible porosity of the soil. There is at least equal to 4.3 million tons of calcium carbonate present in the
infiltration area. This corresponds to a neutralization capacity of 88 x 109 moles in the study area. The annual limestone dissolution in the area is about 750 tons. The limestone content in the area is generally high and has a good ability to buffer also more acidic water than water from Vombsjön. At present limestone consumption, the neutralization capacity lasts for at least 5700 years.
