chlorine, chloramine or both?
Does any one know if Brooklyn water suppliers use chloramine only or both chloramine and chlorine to treat our water supplies?

here is a statement from DEP, I don't see chloramine mentioned anywhere.
All surface water and groundwater entering New York City’s distribution system is treated with chlorine, fluoride, food grade phosphoric acid and, in some cases, sodium hydroxide. New York City uses chlorine to meet the New York State Sanitary Code and federal Safe Drinking Water Act (SDWA) disinfection requirements. Fluoride, at a concentration of one part per million, is added to help prevent tooth decay and has been added since 1966 in accordance with the New York City Health Code. Phosphoric acid is added to create a protective film on pipes that reduces the release of metals such as lead from household plumbing. Sodium hydroxide is added to Catskill/Delaware water to raise the pH and reduce corrosivity. and here are full reports http://www.nyc.gov/html/dep/html/dri.../wsstate.shtml Any more info can be obtained by calling DEP directly. |

Thanks Bderen!
Now I know I can just age my water to get rid of chlorine instead of spending money on a dechlorinator. |

Even though chlorine does disapates, it is still good practice to aerate your water, a small air stone or power head will do fine. Stagent water is very low in oxeqen.

You can certainly do that. I've done some tests trying to measure afficiency of Stress coat and found that it's plenty enough to add a drop for every 2 gallons. Chloring/Chloramine strips showed 0 after about 5-10 seconds of stirring the water.
