    Default Monster 40B: New evidence on viruses -- kids at Camp Chickami at risk

    Please attend the big ZBA hearing on the Cascade / Monster 40B! Tuesday the 27th at 7pm in the large hearing room in the Wayland Town building.

    ProtectWayland experts will present important new evidence: pathogens from septic leach fields can travel over 200 feet through soil and ground water. The Monster's big leach fields are just 64 and 74 feet from the wetlands connected to Pine Brook, and the septic mound is only 42 feet from the Brook itself. (See the site diagram below.)

    Enteric viruses are a key threat (e.g., Adenoviruses, Rotaviruses, Noroviruses, Hepatitis A and E). Infections are associated with diarrhea and gastroenteritis and may also cause respiratory infections, conjunctivitis, hepatitis and diseases that have high mortality rates, such as aseptic meningitis, encephalitis, and paralysis in immunocompromised individuals. In addition, some enteric viruses have been linked to chronic diseases such as myocarditis and insulin-dependent diabetes.

    Should this be upstream from hundreds of kids at Camp Chickami?!!

    Here is a copy of the statement on pathogens in septic effluent and the disease risk to children at Camp Chickami, from ProtectWayland's Title 5 and water quality expert, Scott Horsley:

    Pathogens

    The proposed wastewater discharge will include significant loads of pathogens including bacteria and viruses. While some bacteria are likely to be attenuated within short distances of a septic system, viruses have been shown to travel in groundwater for significant distances of 200 feet or more. An EPA report provides guidance on virus transport in groundwater (AzadpourKeeley et al., 2003) and suggests that local hydrogeologic factors including short setbacks, travel times, and permeable geologic materials all contribute to vulnerability for virus
    transport.

    Enteric viruses are considerably smaller than bacteria and therefore are transported more readily from septic sources through porous media
    such as the soils reported on this project site. They survive for longer periods of time in colder groundwater temperatures such as those in Massachusetts. A widely referenced study demonstrated that viruses can travel distances greater than 200 feet in groundwater (Vaughn, et al. 1983).

    Microbial contamination is important because, unlike most chemical contaminants, human infection and disease results from ingestion of
    low quantities of microbial pathogens, particularly enteric viruses (e.g., Adenoviruses, Rotaviruses, Noroviruses, Hepatitis A and E). Enteric virus infections are associated with diarrhea and gastroenteritis in humans and may also cause respiratory infections, conjunctivitis, hepatitis, and diseases that have high mortality rates, such as aseptic meningitis, encephalitis, and paralysis in immunocompromised individuals . In addition, some enteric viruses have been linked to chronic diseases such as myocarditis and insulin-dependent diabetes (Richard et. Al, 2004).

    The Cascade Project site exhibits these vulnerable conditions and therefore warrants a careful analysis of pathogen transport to
    determine an appropriate setback distance from Pine Brook to ensure that pathogens are not discharged to the brook. YMCA Camp Chickami is located directly downstream of the proposed development. This facility is reported to utilize the brook and attached ponds as a play area for children, who would be put at risk if a major source of pathogens is introduced into Pine Brook.
