Did you know that rainwater is slightly acidic, and in some cases can be very acidic? This can cause acidic groundwater and might cause your well water to be corrosive to plumbing, fixtures, and appliances. Common causes for acidic well water are from acid rainfall due to atmospheric carbon dioxide and other airborne pollutants,and in some cases, runoff from mines. Pure water has a pH of 7.0 (neutral); however, natural, unpolluted rainwater has a pH of about 5.6 (acidic). The acidity of rainwater comes from the natural presence of three substances (Carbon dioxide, nitrogen oxide and sulfur dioxide) CO2, NO, and SO2. (CO2) is present in the greatest concentration and therefore contributes the most to the natural acidity of rainwater. As CO2 levels rise, acid rain might be increasing as well. Some items I talk about in this episode are the source of acid water, how it is formed, and what you can do about it. How to Neutralize Acidic Well Water? * Test your well water first, for at lea...
