Canaan Lake Invasive Species Remediation
We evaluated ways to successfully eradicate/minimize invasive aquatic species in Canaan Lake to allow for additional recreational activities.

PWGC was selected to evaluate alternatives to successfully eradicate/minimize invasive aquatic species in Canaan Lake to allow for additional recreational activities.

PWGC provided professional engineering services in order to:

  • Evaluate the current condition of the invasive aquatic species in Canaan Lake
    Review available environmental studies and reports related to the past history of Canaan Lake
  • Develop remedial alternatives along with constraints and costs for discussion with stakeholders
  • Meeting with regulatory agencies to discuss similar projects and determine what remedial strategies may be allowed
  • Meetings with the public to discuss the strategy and obtain stakeholder input
  • Design the new culvert and sluice gate to draw down the lake

PWGC staff members provided engineering evaluation of proposed dewatering effort, preliminary design of drawdown culvert, overall project management, coordination services with various government agencies and stakeholders, evaluated sediment quality for disposal and pricing options and prepared alternative analysis for evaluation.

An unique aspect to this project is that although the tasks of project were common to PWGC (document review, sediment quality review, coordination with NYSDEC, water table drawdown calculations), PWGC had to really focus on new approaches not used locally to solve a problem with serious permitting,  responsible party, and cost constraints.

Sample Projects
Post-Dredging Ecological Assessment for Upper Lake
After the Upper Lake was dredged to remove invasive species, we conducted an ecological study to measure the dredging's effectiveness
Hydrogeological Assessment for Huntington Ready Mix Concrete, Inc.
We performed a hydrogeologic assessment as part of an application to modify a Mined Land Reclamation Law permit.
Residential Drinking Water Treatment Design & Oversight for Suffolk County Dept. Health Services
We designed and installed treatment systems for private water wells with high levels of the pollutants PFOA and PFOS.
