Great family gift for under $50 for Rainwater Harvesters

With the current lava eruption is it vital to keep minerals in your catchment.
​
Uncle Tilo's Acid Rain Minerals are designed for Hawai'i Rainwater Harvesters.

​Rain is corrosive and considered acidic when it has a pH less than 5.6.
The more acidic the water, the greater the problem with
leaching of lead into the water.

Your house was built with materials containing a variety of metals:

​Iron             pumps, appliances, roofing materials, and metal fittings
Copper       pipes and fittings
Lead           found in all brass ( fittings and plumbing fixtures)
Cadmium  found in galvanized metal
Zinc            found in roofing materials and metal fittings

​In Hawai‘i, the greatest cause of acid rain is fumes from volcanic activity. Erupting volcanoes release gases, particularly sulfur dioxide (SO2 ). In a series of reactions in the atmosphere, the SO2 combines with water molecules, forming a dilute sulfuric acid that returns to the earth as acid rain. Kilauea volcano releases 350 metric tons per day of SO2 during eruptive pauses and 1850 metric tons per day during active eruption.  

Hot water can increase leaching of lead and other contaminants, so hot water from the tap should not be consumed. It is always a good idea to flush the standing water from the faucet, particularly after the water has been sitting in the faucet for a long period of time. 

​Acid rain caught in catchment systems does not have the opportunity to benefit from the earth’s natural buffers. The water in catchment tanks in Hawai‘i that are downwind of the volcanic plume has often had pH readings as low as 4.

To raise pH levels, you can raise the pH in your tank by adding baking soda (sodium bicarbonate), granulated calcium carbonate (also known as calcite), or sodium carbonate (soda ash). Uncle Tilo's Acid Rain Minerals contain calcium and magnesium.  Baking soda is probably the most common treatment used because it is easy and inexpensive to obtain. Also, baking soda acts as a neutralizer rather than just raising the pH. This means there is no worry about the pH becoming too high. When adding baking soda dissolve it in water and pour into the tank, stirring it around as much as possible. 

Neutral water has a pH of 7.0. A great range to be in is 6.5–8.5. It is good to keep the pH above 6.0 to reduce leaching, particularly if there is metal in the system. Water with a lower pH is a health concern one should be mindful of dental health.

Healthy Reminders

Bacteria, viruses, protozoans, parasitic worms, heavy metals, and chemical contaminants all threaten the quality of your drinking water— and your health. Because leptospirosis and possibly other parasites can enter the body through cuts and soft mucous membranes, you should treat all your household water, not just your drinking water with a disinfection method that kills pathogens not just "inactivates/sterilizes".
