PUBLIC HEALTH ASSESSMENT
GROVELAND, ESSEX COUNTY, MASSACHUSETTS
Based on the information reviewed, ATSDR and MDPH has concludedthat this site posed a past public health hazard because of thepotential risk to human health resulting from past exposure tohazardous substances that may result in adverse health effects. Asnoted in the public health implications section, exposure tohazardous TCE levels via ingestion of municipal drinking waterprobably occurred prior to 1979. Currently, there is no publichealth hazard associated with the site.
- Analyses of data from the Massachusetts Cancer Registry failed to detect any statistically significant differences in cancer incidence rates experienced in Groveland and West Newbury from those for the Commonwealth as a whole. For numerous anatomical sites of concern, however, the number of cancer cases was too low to evaluate statistical significance.
- A contamination plume of TCE and 1,2-DCE is migrating northward from the Valley Manufactured Products Inc. plant. Considering the uncertainty of future hydrogeological conditions and the possibility of chemical transformation of TCE to vinyl chloride, removal of TCE contamination from site ground water is necessary to protect the future public health of the Groveland community.
- The current ground water extraction system at Mill Pond is not completely capturing the contaminated bedrock ground water in that area. In addition, emissions from the air strippers are not presently being filtered and as a result, unknown TCE levels are being released. Estimated TCE emission levels are in all likelihood not hazardous.
- Current ingestion of waters drawn from the Station 1 Groveland municipal well does not pose a health threat.
- Hazardous levels of TCE, arsenic, lead and 1,2-DCE weredetected in ground water monitored from wells drilledthroughout the site. No hazardous contamination levels were,however, detected in wells whose waters are known to beingested.
In order to protect the public health of individuals engaged inactivities on or near the Groveland Wells site, the MDPH inconjunction with ATSDR puts forth the following recommendations:
- The Station 1 Groveland Municipal Well and the known private well in the area should continued to be regularly monitored for VOC, lead and arsenic contamination.
- TCE emissions from the air stripping tower at the Mill Pond extraction system should be monitored.
- Warnings against the consumption of Mill Pond waters should be considered.
- A recommendation to the appropriate state and federal labor officials should be made to monitor indoor VOC levels at the Valley plant.
- Monitoring of cancer incidence rates by the MDPH for Grovelandand West Newbury should continue.
HEALTH ACTIVITIES RECOMMENDATION PANEL (HARP) RECOMMENDATION
The data and information contained in this public health assessmentfor the Groveland Wells site is currently being evaluated byATSDR's Health Activities Recommendation Panel to determineappropriate follow-up health activities. Since citizens ofGroveland and West Newbury were at risk of exposure to TCE in thepast and allegations that neurobehavioral disorders resulted fromsuch exposure, the panel determined that those individuals believedto be exposed to TCE be considered for ATSDRs TCE subregistry. Thesubregistry has, however, reached full capacity and therefore nonew individuals can be presently enrolled. Health information andpertinent findings pertaining to this subregistry should also bedisseminated to the citizens from these communities. Furthermore,the panel determined that the agency in conjunction with theMassachusetts Department of Public Health should assess thefeasibility of conducting a community health investigation ofneurobehavioral deficits in the impacted communities. Finally thepanel recommended that a dose-reconstruction be conducted so thatthe length of time residents of Groveland and West Newbury wereexposed to TCE-contaminated drinking water can be more accuratelyestimated.
The Public Health Action Plan for the Groveland Wells NPL Sitecontains a description of actions to be taken by ATSDR and/or theMDPH at and in the vicinity of the site subsequent to thecompletion of the this Public Health Assessment. For those actionstaken at the site, please see the Background section of thisdocument. The purpose of the PHAP is to ensure that this healthassessment not only identifies public health hazards but providesa plan of action designed to mitigate and prevent adverse humanhealth effects resulting from exposure to hazardous substances inthe environment. Included is a commitment on the part ofATSDR/MDPH to ensure that it is implemented. The public healthactions to be implemented are as follows:
- The Bureau of Environmental Health Assessment at MDPH will discuss with ATSDR the feasibility of conducting a health investigation of neurobehavioral deficits in the impacted communities.
- The Bureau of Environmental Health Assessment at MDPH will discuss with ATSDR the feasibility of their conducting a ground water dose reconstruction in order to estimate the length of time residents of Groveland and West Newbury were exposed to TCE-contaminated drinking water.
- The Bureau of Environmental Health Assessment at MDPH will provide information from the ATSDR TCE exposure subregistry to interested citizens.
- The Massachusetts Department of Environmental Protection will continue routine monitoring of municipal water quality in Groveland.
- The Bureau of Environmental Health Assessment will assess the possibility of conducting indoor air monitoring for VOCs inside of the Valley Manufactured Products plant.
- The Bureau of Environmental Health Assessment within MDPH willcontinue to monitor cancer incidence rates for the towns ofGroveland and West Newbury.
The public health assessment for the Groveland Wells site wasprepared by the Massachusetts Department of Public Health under acooperative agreement with the Agency for Toxic Substances andDisease Registry (ATSDR). It is in accordance with approvedmethodology and procedures existing at the time the public healthassessment was begun.
