MUNICIPAL ALERT: Herbicide Treatment in the D&R Canal to Combat Invasive Aquatic Weed to Begin in mid-May

Release date: 5/18/2017

The New Jersey Water Supply Authority is working cooperatively with NJDEP and DRCC and the many Canal interest groups to implement a comprehensive plan designed to contain the spread of the invasive aquatic plant “Hydrilla,” an invasive aquatic weed that is an emerging threat in the state.

The New Jersey Water Supply Authority (NJWSA) maintains and operates the D&R Canal as part of the Raritan Basin Water Supply system. This system serves approximately 1,500,000 residents of central New Jersey. The NJWSA is working cooperatively with NJDEP, the D&R Canal Commission and a variety of Canal interest groups to implement a comprehensive plan designed to contain the spread of Hydrilla. Hydrilla is an invasive aquatic weed that is an emerging threat in New Jersey.  It has been found in the Canal but is not yet well-established in the State. Hydrilla can form dense mats that can choke water flow, clog culverts and pipes, and has been documented to alter water chemistry – pH, dissolved oxygen, and temperature.  It can grow an inch or more every day.  If the hydrilla infestation is not contained, it has the potential to reduce water flow in the Canal by up to 85%, thereby jeopardizing the Canal’s effectiveness as a water supply system and its use for recreation. The spread of hydrilla also poses significant harmful ecological consequences due to its negative effects on water quality.

As part of a three-year management plan, the NJWSA has determined that it is necessary to initiate a low dose, 120-day exposure, injection of a herbicide called Solar Genesis (EPA # 67690-54, active ingredient: fluridone) into the Canal.  SOLitude Lake Management, the Authority’s contractor, will start treatments approximately mid-May subject to receiving all necessary approvals. Spot hydro-raking will also be utilized as needed. The herbicide will not harm people, animals or fish in the low concentrations that are being introduced into the water (<5ppb). There will be no water use restrictions for water consumption, fishing, fish consumption or swimming.  Some irrigation restrictions will be imposed for nursery and greenhouse plants as well as specific crops and newly seeded areas.

Signage will be posted at access areas along the Canal’s entire length to alert the public of the threat posed by hydrilla and to inform them about the herbicide treatment.  Additional information is available at http://www.njwsa.org/hydrilla.html.   Please check the attached FAQ for additional information about this threat.
