    5/8/2019

    Nestled in the Finger Lakes region in upstate New York, the town of Owasco is a popular vacation spot. With about 4,000 residents, the town, along with the nearby community of Auburn, relies on Owasco Lake for its drinking water. In 2016, Owasco and Auburn detected algal toxins in their finished water for the first time. With the busy summer tourist season quickly approaching, GHD contacted Calgon Carbon.

  10. On-Site Sodium Hypochlorite Generation Maintains Consistent Chloramine Disinfectant Residual At A Remote Tank
    5/7/2019

    Purissima Hills Water District (PHWD), a county water district, provides chloraminated water service to two-thirds of the town of Los Altos Hills, adjacent to the city of Palo Alto in Northern California. With remote tank locations, low population density (6,800 people) and low water demand (1.61MGD), PHWD is constantly challenged to maintain consistent disinfectant residual levels while simultaneously balancing the safe delivery of chemicals to its tank site at an affordable cost.
