Groundwater - found below the ground where it accumulated in between soil and rocks. The volume of water can range from small to very large similar to above ground creeks, rivers and lakes.
Results: Since there is no Canadian Drinking Water Guideline for Ammonia you will compare results to the European Union limit. The standard should give a result very close to the 0.5 mg/L colour; if the colour is darker then it DOES NOT meet the guidelines.
