The nitrate level of water provides an indication of potential contamination. With a very low nitrate level of 0.061 mg/l, the purity of our water is considered to be superior by international standards.
The level of Total Dissolved Solids (TDS) in mineral water is a measure of the mineral content of the water. Low levels of the right minerals enhance the well being benefits of the water. Our water has a TDS level of 140 mg/litre, which is classified as low; mineral waters with high minerality have a TDS exceeding 1500 mg/litre and are deemed to be lower quality.
