June 19, 2026, 4:31 a.m. ET People in Endicott are concerned about security, safety and street conditions. But the main complaint is brown water. According to a study by Hunt Engineering, the water from the Rainey well has a lot of black manganese iron in it. Chlorine must be added to all public water. When combined with the black manganese iron, the water turns brown. Water from the Rainey well is pumped to a number of water tanks. The black manganese iron settles in each water tank.
