	1.-		Air pollution increases acid rain and degrades the atmospheric ozone that protects the earth from ultraviolet (UV) radiation. How does this impact lake water quality?


	2.-		Are there any potential risks associated with using magnesium oxide versus carbonates of calcium or magnesium in the filter media for neutralizing acidic water to reduce corrosion?


	3.-		At what pH range will polyphosphates and silicates remain effective in sequestering iron to keep it in solution and prevent staining and discoloration due to ferric hydroxide precipitation in water?


	4.-		Can a small amount of hydrogen sulfide in water cause pinhole corrosion in copper water pipes?


	5.-		Can an acid neutralizing filter using magnesium oxide or calcite be clogged by precipitates formed within the filter media?


	6.-		Can climate change impact the formation of acidic water problems?


	7.-		Can copper ions from corrosion react with soap to create blue or green stains?


	8.-		Can lightning in the atmosphere produce nitrate nitrogen that is then brought down in rainfall?


	9.-		Can we restore an acid rain damaged environment?


	10.-		Do acid neutralizing systems increase water hardness?


	11.-		Do all regions have the same capacity to neutralize acid rain?


	12.-		Do silicates have any advantage or disadvantage in comparison to polyphosphates for sequestering iron and manganese in water to prevent staining problems?


	13.-		Does a blue/green stain in my sink or tub mean I have a corrosion problem?


	14.-		Does acid rain contribute to the decay of buildings and monuments?


	15.-		Does controlling acid rain cause other problems?


	16.-		Does soluble silicate (SiO2) work effectively to inhibit pipe corrosion in both acidic and alkaline waters of distribution systems?


	17.-		Does water become more corrosive when hydrogen peroxide (H2O2) is injected into the water?


	18.-		How are pipe loops and coupons used to test for corrosion potential within a water distribution system?


	19.-		How are we solving the acid rain problem nationally?


	20.-		How do I know my drinking water is acidic?


	21.-		How do orthophosphates inhibit corrosion and leaching of elements from piping within water distribution and plumbing systems?


	22.-		How do power generation utilities control acid gas emissions?


	23.-		How do we measure acid rain?


	24.-		How do you measure corrosion potential of metal components such as storage tanks and pipes used in water infrastructure systems?


	25.-		How do you prevent and control acid mine drainage?


	26.-		How do you prevent corrosion of light fixtures, rails, and ladders in swimming pools?


	27.-		How do you treat corrosion of your plumbing system due to acid source water?


	28.-		How do zinc orthophosphates inhibit corrosion inside water distribution systems and does this corrosion control have other benefits?


	29.-		How does acid deposition affect aquatic ecosystems?


	30.-		How does acid deposition affect terrestrial plant life?
