WATER
And then we get to another issue which is the water you use for your nectar. Water is indeed a large issue as we humans feed hummers. Some people use city water, some use via a water softener/ conditioner/ reverse osmosis and some receive their water from wells.
To boil or not to boil?
Often I am asked “Do I need to boil my water for my hummingbird feeders”?
City water has been treated for human consumption, taking out harmful bacteria, etc. It does contain trace elements, as necessary minerals, that humans and hummingbirds need daily. Boiling city water will eliminate chorines, fluorides and any potentially harmful bacteria/ microbes that hummers don't need. Boiling water and eliminating bacteria will retard nectar fermentation by at least an additional 24 hours.
Water softeners/ Reverse osmosis
The common active ingredient in water softeners is sodium (salt) which may add too many minerals and salts to the water. With reverse osmosis and ionization the water can become overly acidic.
Well Water
In well water you may find agricultural chemicals and contaminant run-off may be present in rural and suburban aquifers.
Any boiled water is the preferred water to use. Do not use distilled as it takes out too many naturally occurring minerals
Filtered Waters
You can also use filtered water from a Brita or the refrigerator water filter.
Important if boiling water: Allow the water to cool before adding the nectar---boiling water with nectar will alter the 4:1 water:nectar ratio via evaporation. Also, remember that in hot and arid climates the liquid in the feeder will start evaporating immediately and in a matter of a few days it can change from 4:1 to 3:1 to 2:1 and will be refused by the hummers. Thus, it is best to clean the feeder and replace the nectar every two-three days.
Lead in Water
Some say:
“The Centers for Disease Control and Prevention warn against using hot tap water for drinking or cooking, because hot water can pick up lead from plumbing and fixtures. Unlike sucrose, lead isn't any healthier for hummingbirds than it is for humans. Whether you use this product or plain sugar, use water heated on the stovetop, in an electric kettle, or in a microwave oven, not from the hot-water tap”.
The New York Times Claim: Never Drink Hot Water from the Tap
The claim has the ring of a myth. But environmental scientists say it is real.
The reason is that hot water dissolves contaminants more quickly than cold water, and many pipes in homes contain lead that can leach into water. And lead can damage the brain and nervous system, especially in young children.
Lead is rarely found in source water, but can enter it through corroded plumbing. The Environmental Protection Agency says that older homes are more likely to have lead pipes and fixtures, but that even newer plumbing advertised as “lead-free” can still contain as much as 8 percent lead. A study published in The Journal of Environmental Health in 2002 found that tap water represented 14 to 20 percent of total lead exposure.
Scientists emphasize that the risk is small. But to minimize it, the E.P.A. says cold tap water should always be used for preparing baby formula, cooking and drinking. It also warns that boiling water does not remove lead but can actually increase its concentration.

I agree with the above and add:
If lead is present in any system it will always be present as you are turning on-and-off the hot water and it will always be present in the closed plumbing system.
Boiling does not remove lead but it disinfects the water by removing any bacteria, however, as you boil longer it will concentrate any heavy metals, minerals or other pollutants in it. This will happen because the water will evaporate leaving the same pollutants with less water.
Boiling tap water will cause any bicarbonates to be boiled off as carbon dioxide as well as any chlorine and other volatile compounds. You can get an analysis of the impurities present in your tap water by asking your water supplier. Most cites provides same in each monthly bill. The analysis will show the level of harmless (to drink) impurities such as sulphates, carbonates, sodium, calcium, magnesium etc., chlorine added by them to kill any bugs and hopefully a number of zeros against toxic ions such as lead and mercury, pesticide residues, bacteria and other items.
If you are feeding hummers please be cognizant of what goes into their feeder.
