MassDEP continues to investigate water quality at private wells located on McGilpin Road in Sturbridge.  The request came after citizen testing in the area indicated the presence of 1,4 dioxane in one private well.

MassDEP conducted additional sampling on McGilpin Road on February 8, 2017.  This latest round consisted of resampling at 4 homes as well as new sampling at 5 homes.  The third round of sampling showed low levels of 1,4 dioxane in 1 home. Additionally, 7 homes had detections of lead.  MassDEP continues to provide bottled water to all homes with detections of either lead or dioxane. MassDEP will be evaluating the data collected and plans to resample at all homes that have only one sample round completed to date as well as sample one new home.  Sampling will take place later this week or next week.

Sampling will continue at intervals of 500 feet around each new detection.  This will continue until no detections are discovered.  MassDEP is reviewing private well data provided by the Sturbridge Board of Health and individual residents as part of its investigation.  At a neighborhood meeting on Monday, February 13th, MassDEP committed to working the Sturbridge Board of Health to ensure information on lead in drinking water is available to Sturbridge residents.  We are also assisting the Board of Health in providing information and resources to residents who want to independently have their wells tested.  We will provide a link to the Sturbridge Board of Health website once that information is available.

MassDEP sampled 11 wells on McGilpin Road on or about January 20, 2017.  Three of the 11 homes had detections of 1,4 dioxane at levels below the drinking water guideline.  Additionally, 10 of the 11 homes had detections of lead, with six at levels exceeding the EPA action level of 15 parts per billion (ppb). 

MassDEP conducted a second round of sampling on January 27, 2017.  This new sampling round consisted of resampling at 10 of the 11 original homes as well as new sampling at 4 homes.  Lead sampling in the second round showed different lower levels for four homes.  Two second round samples continued to show elevated lead levels as well as two homes sampled for the first time under MassDEP protocols. We are investigating why lead sampling levels have differed between sampling rounds.

The second round of sampling also showed low levels of 1,4 dioxane in four homes.

All homes (14) with detections of either lead or dioxane are currently receiving bottled water from MassDEP while the agency investigates the possible causes and sources.

MassDEP will be evaluating the data collected and will conduct additional sampling next week.

MassDEP is notifying the homeowners of the latest sampling results. We continue to be in contact with the Sturbridge Board of Health and with affected homeowners.

January 27, 2017
To date, MassDEP has sampled 11 wells on McGilpin Road.  Three of the 11 homes had detections of 1-4 dioxane at levels below the drinking water guidelines.  Additionally, 10 of the 11 homes had detections of lead, with four at levels exceeding the EPA action level of 15 parts per billion (ppb). Other than metals and one volatile organic compound at levels above detection limits but well below regulatory action levels, no other contaminants have been detected in the wells during this sampling effort.

According to MassDEP protocols, MassDEP is performing additional sampling to include private wells within 500 feet of the affected wells.  In the meantime, MassDEP has been in contact with the Sturbridge Board of Health Chair and with homeowners  where sampling has been or will be performed.  MassDEP is offering to provide bottled water to all homes with detections, even where the contamination is below applicable regulatory standards.  MassDEP will continue to provide bottled water until such time as a source and responsible party for the listed contaminants can be identified and/or until the agency  is more definitively able to assess the situation and determine any level of risk.  MassDEP will continue to evaluate this situation, update homeowners and the Sturbridge Board of Health, and will work to determine the source of the contamination and appropriate response actions.
