Health and Safety

  • Bacterial pollution: possible bacterial pollution from previous biosolids/sludge applications to the site
  • Wells and septic systems: impacts on residential septic systems and rural wells
  • Security: security fencing and on-going monitoring of property (e.g. local youth using the lake as a swimming hole)
  • Respiratory health:
    • adverse effects of airborne dust, including quartz and silica particulates, on respiratory health (e.g. asthma, emphysema, silicosis)
    • pollutant emissions from diesel trucks and machinery (e.g. nitrogen oxides, volatile organic compounds – VOCs, carbon monoxide, fine particulate matter)
  • Contamination of drinking water:
    • contaminants such as road salt, gasoline, oil, lubricants and solvents entering the shallow groundwater and deeper aquifers causing contamination of drinking water
    • contamination of water in pit ponds and lakes from increased bird populations (e.g. seagulls, Canada gees, other waterfowl)
  • Disease: mosquito populations in man-made wetlands, ponds and lakes, as well as water laying on pit/quarry floors and the potential for West Nile Virus disease
  • Road safety:
    • gravel trucks pose a potential danger to children riding, boarding and departing school buses.
    • snow blowing over berms causing drifts to build up and icy conditions to form on adjacent roads
    • increased icing of roads in the fall and winter from evaporation, condensation and moisture in the air rising from pit/quarry ponds and lakes
