Karen Petinelli, an environmental planner at the Southeast Regional Planning and Economic Development District, told the commission the project will place 11 small-diameter borings and install four permanent groundwater monitoring wells to assess nitrogen concentrations and the feasibility of a pilot PRB. “It pulls, like, 90% of the nitrogen from the groundwater out of of the groundwater before it enters the pond,” Petinelli said, describing the technology.

The study will sample groundwater horizontally and vertically along about 4,000 feet of corridor to identify a 200- to 400-foot pilot stretch for a PRB. “We’re looking to assess where best to import a a pilot study…we’re looking at a stretch of about 200 to 400 feet,” said an engineer from Fuss & O’Neil, who described field instrumentation, laboratory confirmatory testing and the plan to place monitoring wells upgradient and down-gradient of any pilot installation.

Why it matters: Long Pond has persistent nitrogen and water-quality problems. The pilot is intended to test whether an in-ground reactive media (wood chips or emulsified vegetable oil) can trap legacy nitrogen in groundwater before it reaches the pond and inform a potential larger installation later. Petinelli said the project is funded with state-allocated follow-up money that is being administered through the Division of Ecological Restoration as part of a municipal vulnerability/ watershed program.

Commission discussion focused on maintenance, longevity and cost responsibility. Commissioners asked who would pay for future reinjection or replacement if the media loses effectiveness. The consultants described two common media approaches: a wood-chip trench and injections of emulsified vegetable oil (EVO). The consultants said field experience shows PRBs may remain effective for multiple years; one speaker said “these PRBs…will last 4 to 7 years,” and the group also referenced longer estimates for wood chips in some cases.

The consultants said PRB design depends on groundwater depth, hydraulic conductivity and vertical concentration profiles. If groundwater is shallow and impacted near the surface, a trench filled with organic material may be preferable; if impacts are deeper, EVO injections may work better. The team also said trenches or columns would be backfilled and finished to restore the roadway or vegetated surface; temporary siltation controls would be used during drilling and well installation.

Public and owner engagement: Petinelli said the project leader had met with Clark Shores association members and that the association had approved moving forward with the feasibility study. Drilling for the borings was announced as scheduled for the coming Monday, Tuesday and Friday; the team asked to be reachable by phone to obtain the commission’s determination before field work begins.

Vote and conditions: The commission closed the hearing and issued a negative determination allowing the borings and monitoring-well installation, with two conditions: (1) if any siltation control or barriers will be used around the wells, the applicant must notify the commission’s agent in advance for inspection and (2) the applicant must provide the monitoring data and feasibility report to the commission when available. A motion to issue the determination passed (mover/second not specified on the record). The commission member asked that the applicant deliver the study results to the commission and preferred that the applicant notify staff before work on siltation barriers began.

Next steps: The feasibility study will collect field parameters (pH, temperature, oxidation-reduction potential, dissolved oxygen, ammonia, nitrate and sulfate), send select samples to a lab for confirmation, and use those data to size a pilot PRB. If the pilot shows positive results, the team would seek additional funding and permits for a larger installation (consultants referenced a possible future design length of roughly 1,500 feet identified in earlier watershed work).","mediaType","Video","parentTitle","Lakeville Conservation Commission, 4-8-25","oneSentenceSummary","The Lakeville Conservation Commission on April 8 voted to close a public hearing and issue a negative determination allowing a feasibility study for a permeable reactive barrier along the western shore of Long Pond near Clark Shores.","taxTitle","Town of Lakeville, Plymouth County, Massachusetts","taxId",58187,"location","Massachusetts","headline","","shortSummary",{"_33":77,"_35":36,"_37":38,"_39":78,"_41":79,"_43":80,"_45":81,"_47":82,"_49":83,"_51":84,"_53":85,"_55":56,"_57":58,"_59":86,"_61":62,"_63":64,"_65":87,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6606243,"Meeting roundup: continuances, minutes and other procedural votes from April 8 Lakeville Conservation Commission",3534,72000,3606000,"/Search/View?dp=1&key=2972732-de1ed984752a6be92fc1713cdc295f2f&start=72&end=3606","https://assets.pipeline.soar.com/2972732-de1ed984752a6be92fc1713cdc295f2f/thumbnail_72000.jpg","/articles/6606243/Massachusetts/Meeting-roundup-continuances-minutes-and-other-procedural-votes-from-April-8-Lakeville-Conservation-Commission","https://secure.pipeline.soar.com/6606243-9d59ab023adf380df7a0b27e8360dec4/orig.mp4?Expires=1774810944&Signature=Hktc4OZtbAqxaIlmuuxAhkxyhxPrxUgQ0yI0PhYA5VJ9NHH2lN-2cMxnUG3CrQr4lDqrETVh1i8iZjfNj8efZP5U6L7xSJPkLGyYU2YHZYm2qqyeSxG62F-oW0pn5aSzJHP1rsxTNMX7AJGx0qIYYJldHhnbamN90EsaMalL2TZPoYcxYdAyqJZUw3pw8LgPhGxduMayzKEEG4j3FcOUsO64hPzSzH97--kd4j-mb~RIp0D6T~InSZ--F-QJk2-m96XiCud3LiCjgN5i0gyWIhInv2Cg40JAUVHgcrVzWGF0YdFxGyH5Ftgbb3JHZtB4kkp2jNVnNDqdH57~v9amBw__&Key-Pair-Id=KUT5TJCACFTXG","At its April 8 meeting the Lakeville Conservation Commission recorded multiple procedural votes and continuances.

Commissioners noted scheduling reasons for continuances (absences of members and need for additional materials). Where applicants were to proceed with near-term field work (for example, borings approved under the PRB feasibility study), staff instructed applicants to call the conservation office to obtain the determination prior to beginning work.","The commission recorded several continuances and routine votes during its April 8 meeting, including continued hearings and acceptance of minutes from January 14, 2025.",{"_33":89,"_35":36,"_37":38,"_39":90,"_41":91,"_43":92,"_45":93,"_47":94,"_49":95,"_51":96,"_53":97,"_55":56,"_57":58,"_59":98,"_61":62,"_63":64,"_65":99,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6606245,"Commission ratifies enforcement order after discovering large fill piles at 160 Bedford Street; case continued",280,3675000,3955000,"/Search/View?dp=1&key=2972732-de1ed984752a6be92fc1713cdc295f2f&start=3675&end=3955","https://assets.pipeline.soar.com/2972732-de1ed984752a6be92fc1713cdc295f2f/thumbnail_3675000.jpg","/articles/6606245/Massachusetts/Commission-ratifies-enforcement-order-after-discovering-large-fill-piles-at-160-Bedford-Street-case-continued","https://secure.pipeline.soar.com/6606245-edd467a03ed793181e89988d27481f37/orig.mp4?Expires=1774810944&Signature=hTOKfHyebA9KHOUk4Wzjp2l5P5z8pcglzdDr39Pnhfn9FQB91~CPLyfCdKi0O7RhCeDLeHex5XctZQIffpYr3bkBop3bNwQ3PHoSWwnVGqV~OMNuwsd4A7QA~40Eba64tUKHjaGyq1ZK9rJ~fglzR~Dr~lTEZfpw~FjnQW2vP0wvazlTs9t1i~BAUXNsXawB7XbVFys~gersZyPv0uQLEHnDxj63hf8c1JDDgFD8f3IWnzQAgwDB0RBYAQHZjMv7jwog9sFa0u22C8gDGIh8sv4aBgKFXRa92hMLjGWBtqqX4KTIhJ18JwPxST1Nomq-1~CwUsSVVtCC8s27MatMFQ__&Key-Pair-Id=KUT5TJCACFTXG","The Lakeville Conservation Commission on April 8 ratified an enforcement order addressing substantial stockpiles and site activity at 160 Bedford Street and continued the applicant’s pending filing to the April 22 meeting to allow a peer-review response.

Conservation staff reported photographs showing large piles of construction material near wetland limits. The commission’s agent said the contractor asserted the material had been used to fill borings, but a site consultant’s follow-up visit found no open borings to justify the volume observed. The commission’s agent said he had issued an enforcement order and recommended notifying the Massachusetts Department of Environmental Protection (DEP) if further action were required.

The commission voted to ratify the enforcement order and asked staff to forward the site photos and enforcement materials to the commission’s DEP contact. The commission also accepted a peer-review engagement; the peer reviewer has been asked to evaluate the filing and the enforcement-related concerns and will respond to the commission and applicant. The applicant’s filing was continued to the April 22 meeting to allow time for the applicant to respond to the peer-review comments.

Vote and procedural notes: The commission’s motion to ratify the enforcement order carried by voice vote. A subsequent motion to continue the notice of intent/related filing for 160 Bedford Street to April 22 passed. The commission asked that the applicant and consultant provide responses at least one week before the next meeting so commissioners and the peer reviewer can review the materials.","The conservation commission ratified an enforcement order for work and large piles of fill observed at 160 Bedford Street and continued the applicant’s filing to April 22 while a peer review and response are prepared.",{"_33":101,"_35":36,"_37":38,"_39":102,"_41":103,"_43":104,"_45":105,"_47":106,"_49":107,"_51":108,"_53":109,"_55":56,"_57":58,"_59":110,"_61":62,"_63":64,"_65":111,"_67":68,"_69":70,"_71":72,"_73":74,"_75":74},6606249,"Conservation commission issues ORAD for 12 Southworth Street; no work proposed",1286,2354000,3640000,"/Search/View?dp=1&key=2972732-de1ed984752a6be92fc1713cdc295f2f&start=2354&end=3640","https://assets.pipeline.soar.com/2972732-de1ed984752a6be92fc1713cdc295f2f/thumbnail_2354000.jpg","/articles/6606249/Massachusetts/Conservation-commission-issues-ORAD-for-12-Southworth-Street-no-work-proposed","https://secure.pipeline.soar.com/6606249-69e5d597f0992a2dcaeecfdc3eed09b7/orig.mp4?Expires=1774810944&Signature=K2EFhLYG2~uTOZ9K2JOj7IqzN0no3QTC5abCuF3smulerw2jcs3ZVydH5zf5DiHwB7OZtTBHZFx-~nbl2pS4LvpIjdw1OVHyF8CJmncIAarb7DHGpr7KdyMQgNF8i-y~YHRZKCEnIMG2avXhOTALqXRpMdeTGOWsclhHMlW1LROk2yjVrJYG3~qX~vCkv7hWC34w2O0xw8y5jwqVTct1~EZZ-hZiYZoZvzqeTYI1FqJkjNs-1WYMxJXMmBW40UCdFY0QeoSmFKo~p~YeOVJ3mDeGwXw07FiFheb8aztIU8Xfp5x4PjjFmed5~Um2WKAwCRu5r7rqLu92GFxFh3kp8w__&Key-Pair-Id=KUT5TJCACFTXG","The Lakeville Conservation Commission on April 8 closed a public hearing and issued an Order of Resource Area Delineation (ORAD) that confirms the wetland boundary behind the property at 12 Southworth Street (Map 25, Block 3, Lot 7), an undeveloped parcel that includes the old Chase house.

Jamie Bissonette of Zennep Consulting Engineers presented the AnRAD (abbreviated notice of resource area delineation), explaining the filing’s limited purpose: to lock in the wetland line that runs behind the existing house, blueberry-bush area and barn. Bissonette and the applicant’s surveyor noted there is likely upland farther east on the parcel but the commission’s ORAD covers only the mapped wetland limit shown on the plan.

The commission discussed the record and the applicant’s survey work. A DP/SE number (SE192936) was noted for the file. Commissioners and neighbors clarified that the ORAD determines only the depicted wetland edge for 12 Southworth and does not pre-approve any development; any future work within 100 feet of the delineated wetland would require a separate filing and public notice.

Lot details and context: the overall parcel was described as about 12.2 acres with roughly 4 to 5 acres of upland toward the front of the site, according to the applicant’s materials and the commission’s review. The commission emphasized that USGS and state mapping (such as MassMapper) are guidance tools; the ORAD reflects ground-truthing by a wetland scientist for the specific parcel under review.

Public comment and process: Several abutters asked about the ORAD implications for wells, septic systems and wildlife habitat. The applicant reiterated that tonight’s action only determines the wetland boundary and that additional permitting would be required for any construction or wetland crossing.

Vote: The commission voted to close the hearing and issue the ORAD for 12 Southworth Street. The motion passed by voice vote (mover/second not specified on record).","The commission issued an Order of Resource Area Delineation (ORAD) confirming a wetland boundary behind the historic Chase property at 12 Southworth Street; the applicant is not proposing development at this time and would be required to file if future work is within 100 feet of the delineated wetland.","actionData","errors"]
