Deicing Facility Mapping Final Report Appendix C, Stephanie E. Hurley, Dana Allen

Lake Champlain Sea Grant Institute

This Appendix is part of the August 2023 Report “Potential drinking water impacts from road salt storage facilities in Vermont’s Lake Champlain Basin” by the University of Vermont and FluidState Consulting. Maps of the location(s) of deicing materials storage facilities in Vermont municipalities within the Lake Champlain Basin are shown in alphabetical order. Drinking water wells in proximity to the facilities are labeled; in some municipalities there are no wells within the distances selected for mapping for the purpose of this project. Locations have not been field-verified and proximity of water sources to deicing material storage facility is not an …

Tile Drainage Flow Partitioning And Phosphorus Export In Vermont Usa, Ryan Ruggiero, Donald Ross, Joshua W. Faulkner

Lake Champlain Sea Grant Institute

Tile drainage (TD) has been identified as a potential non-point source of phosphorus (P) pollution and subsequent water quality issues. Three fields with TD in Vermont USA were monitored to characterize hydrology and P export. Fields were in corn silage and used minimal tillage and cover cropping practices. Preferential flow path (PFP) activity was explored by separating TD flow into flow pathway and source connectivity components using two hydrograph separation techniques, electrical conductivity end member unmixing, and hydrograph recession analysis. TD was the dominant P export pathway because of higher total discharge. Drought conditions during this study limited surface runoff, …

Keeping Dogs Safe From Cyanobacteria Blooms (Habs), Lake Champlain Sea Grant

Lake Champlain Sea Grant Institute

Cyanobacteria blooms (sometimes called Harmful Algal Blooms or HABs) are overgrowths of a type of bacteria that use sunlight to reproduce in lakes and ponds. Cyanobacteria blooms sometimes produce potent toxins that can poison people, pets, and livestock. The presence of these blooms is increasing in many areas, putting both animals and humans at risk.

This brochure will help you understand the risks, how to recognize cyanobacteria blooms, how to keep both you and your dog safe from exposure, as well as what to do if your dog has been exposed to a bloom or poisoned by toxins.

Introducing Lake Champlain Sea Grant And Programs For Real Estate Professionals, Linda Patterson

Lake Champlain Sea Grant Institute

Lake Champlain Sea Grant offers accredited workshops to Vermont and New York real estate professionals. Real estate professionals are often the first (and sometimes only) source of information for buyers and sellers about construction and alterations in regulated areas (such as wetlands and river corridors), potential flood risks, septic requirements, shoreland protection, and related topics. Realtors also gain valuable information about state and local resources that they can pass on to their clients.

All courses award Vermont continuing education credits. New York credits are available for the septic course, with others pending. Courses are listed in the presentation.

Stormwater Subsurface Gravel Wetlands In Vermont: Permitting, Performance, And Chloride Concerns, Watershed Consulting Associates, Llc, University Of Vermont

Lake Champlain Sea Grant Institute

Subsurface gravel wetlands (SGW) are water treatment practices that utilize a saturated bed of gravel and (sometimes) wetland vegetation to filter incoming water and remove pollutants through a combination of physical filtration, adsorption, biological uptake, and microbial transformation. Water level is controlled by an outlet structure to retain a permanent subsurface pool, providing retention of stormwater volume in addition to pollutant removal. SGW are becoming increasingly popular tools for stormwater treatment in Vermont.

A varied group of partners including academic researchers, municipal stormwater managers, and consulting designers and engineers, have identified questions around stormwater gravel wetland performance as significant in …

Literature Review And Comparative Analysis Of Existing Certification And Training Programs Applicable To Clean Water Project Operations And Maintenance, Marc Companion, Anna Hildebrand, Kristine Stepenuck

Lake Champlain Sea Grant Institute

Stormwater runoff that carries sediments and nutrients is a primary pollutant entering surface waters in the State of Vermont. Phosphorus pollution is driving cyanobacteria blooms in many of our lakes including Lake Champlain, Lake Carmi, and Lake Memphremagog, especially in the warmer months. Warmer weather patterns and an increased frequency of extreme storms are predicted with climate change. As such, there is critical need to take action on the land to minimize and treat stormwater runoff on-site.

The State adopted a Clean Water Act in 2015, which was swiftly followed by a Total Maximum Daily Load (TMDL) for Lakes Champlain …

Soaking Up Stormwater Through Education And Stewardship In The Lake Champlain Basin And Beyond, Lake Champlain Sea Grant, University Of Vermont Extension

Lake Champlain Sea Grant Institute

The health of Lake Champlain and other waterbodies in the Lake Champlain basin, which lies within portions of Vermont, New York and Quebec, are negatively impacted by nonpoint sources of pollution, including phosphorus, nitrogen, sediments, chloride, and bacteria. All of this pollution is carried to waterbodies in stormwater runoff. Thus, it is critical that everyone understand what stormwater is, and how to help clean it and reduce its volume before it enters local waterways.

Stormwater is water from rainfall and melting snow or ice that moves over the land, collecting pollutants as it makes its way to lakes, ponds, streams …

Hydrodynamic Modeling Of Lake Champlain: Current Resources, Major Gaps, Mae Kate Campbell, Julianna White

Lake Champlain Sea Grant Institute

Hydrodynamic models are computer-based programs designed to simulate processes and movements in water bodies. Scientists and policymakers use the robust information produced by hydrodynamic models to improve our understanding and develop policies for the protection and future management of water bodies. Current environmental issues in Lake Champlain that are or could be informed by hydrodynamic models include excess nutrients, changing temperature dynamics, flooding, harmful algae blooms, pathogens, contaminants, and invasive species. Existing hydrodynamic models are currently used to forecast flood risk and to determine how seasonal water current and nutrient dynamics affect the occurrence of harmful algae blooms, among other …
