**UPDATED: Kennebunk River Well PFAS Information**

Updated June 8, 2018

The Kennebunk River Well is back on line

(Includes excerpts from KK&W’s summer edition of What’s on Tap, to be published June 25, 2018)

As reported in our winter 2018 edition of What’s on Tap, we are pleased to announce that we have made great progress with the removal of PFAS from the Kennebunk River Well (KRW).  Recently, as a result of extensive pilot testing regarding the best treatment technologies to remove the trace amounts of PFAS, we have partnered with Evoqua Water Technologies to move ahead with a full scale, online 700 gallon per minute pilot test that is being placed in service today, June 8, 2018.  It will run for at least 6 months (processing over 180 million gallons).  This will confirm that the technology will work effectively under “real world” operating conditions before making the decision to invest the estimated $1.3 million that is required to put the KRW permanently back on line.

In anticipation of a successful full scale pilot test, the District has already been preapproved by the Maine Drinking Water Program to receive a $1.3M low interest State Revolving Fund loan (20 year term at about a 1% interest rate) that will be used to purchase the filtration system and construct a permanent enclosure around the pressure vessels and other ancillary equipment.

The total cost of this remediation, including debt service and annual operating costs, will ultimately result in an overall water rate impact of about 2 to 2-1/2% (about 2 to 3 cents per day for the average residential customer), which shouldn’t take effect for a couple years.  From a waterworks perspective, this is a fraction of what a “typical” water utility would pay to resolve such an issue.

More detailed information will soon be mailed to all of our customers in late June in the summer 2018 edition of What’s on Tap.  As always, feel free to contact us with any questions.

In November of 2012, after several years of negotiating, testing, applications, approvals and permits, the Kimball Lane Well (also known as the Kennebunk River Well, or KRW) was placed into service.  The well ran flawlessly since that time, providing approximately one fourth of the District’s total water supply needs.  By all accounts it was producing the best quality of water of any public water groundwater supply in the region.


On April 15, 2016, the District was notified by the Maine Drinking Water Program that a small amount of two man-made chemicals (PFOS and PFOA) were detected in the KRW. The information submitted with the notification described the family of chemicals (known as PFAS) in some detail.  Being that the level detected was 0.05 parts per billion (which is the same as 50 parts per trillion, or 50 PPT) and that the then current EPA-established Health Advisory Level (HAL) was 200 PPT for PFOS and 400 for PFOA, the detection didn’t raise much concern at the time.  After all, the sampling was taken as part of the USEPA’s Unregulated Contaminant Monitoring Rule, Phase 3 (UCMR-3), which is essentially a forward-looking investigation into the existence of chemical contaminants that might be regulated by the USEPA at some point in the future.


On May 25, 2016 the USEPA announced, in the Federal Register, that it had lowered the HAL to 70 PPT for PFOS and PFOA.  Although we fully understood that the HAL was based upon a lifetime of exposure to these contaminants, the lower HAL prompted us to investigate the issue to find the source of the contaminants and to also determine the likely fate of the KRW as a long-term source of water.   We began our own testing of the KRW and of its surrounding monitoring wells for PFOS and PFOA in an attempt to find the source of the contaminants. Being that the relatively new and elaborate test had a 25 to 30-day turn-around time, it took several months to finally determine what direction the contaminants were coming from.  The determination (which later proved to be accurate) was that the contaminants came from material that was spread on a farm field in Arundel, across the Kennebunk River from the District’s KRW.   In November of 2016 we notified the farmer of the issue and supplied him with some pertinent information on the topic.


During this process we were also educating ourselves about these contaminants, including scientific, regulatory and societal perspectives.  By February of 2017 we chose to shut down the KRW as a precautionary measure.  Our justification for doing so was multi-faceted, and can be best explained as follows:

  1. There was ongoing discussion, on state and federal levels as to the appropriateness of 70 PPT as the HAL. Some states were proposing 20 PPT or less.
  2. In dealing with the EPA and the Maine Department of Environmental Protection (DEP) it was becoming increasingly apparent that any regulatory direction (in the form of new guidance or standards) was not going to occur for months, if not years.
  3. We weren’t in desperate need of the well during the low-demand winter months and we could shift the load to our Branch Brook Filtration Plant until more information was available or until the issue was resolved

Since shutting down the KRW, we have begun conducting pilot studies to determine the best and most cost-effective process for the long-term removal of the contaminants from KRW’s water.  When it comes to water quality, we have a long history of consistently erring on the side of caution, deferring to our in-house motto, “When in doubt, leave it out”.


At about that time we also began a more intensive dialog with the DEP and provided all of our information and findings to them for their investigation into the source(s) of the contamination.  Several months later they issued a Phase 1 report, which confirmed our findings; the contamination came from the spreading of paper mill ash and/or sludge on the neighboring farm fields about 30 years ago, which was approved by the DEP at that time.  Being that this study was described by the DEP as being preliminary, the District agreed to their request that the study and its results not be publicized until the purportedly more conclusive Phase 2 study was completed.  With this understanding but with EPA’s requirement that we post any detected UCMR-3 results on our annually published Consumer Confidence Report (CCR), we informed the DEP that we needed to comply with our primary regulatory agency’s requirements. The DEP then requested to see what we were going to publish. We then submitted our draft CCR to them.


As time went by we were becoming concerned that the DEP Phase 2 report had not yet been completed and were becoming increasingly uncomfortable with our prior agreement with the DEP, especially in light of news reports of related incidents involving PFAS in the region.  We informed them of our concern.  On July 28th, 2017 the DEP gave us their Phase 2 report.  From our perspective, it provided no conclusive insight into the issue.  We then realized that we were really on our own. Being that a local dairy farm had been shut down and that some legal action had been threatened between some of the other involved parties, we found ourselves in a very uncomfortable position.  Even though we had done the right thing for our customers by erring on the side of caution, we were uncomfortable and frustrated with the whole situation.


After much deliberation we then decided to go public with what we knew.  The plan was to roll it out in January of 2018.   We were to time a public presentation with the publication of our semi-annual newsletter, What’s on Tap, along with a presentation at the Maine Water Utilities Association’s annual convention in Portland. Everything was executed as planned, with the exception of the publication of the newsletter, which is now being printed and should be in our customers’ hands by around February 25th.


In closing, by having only operated the Kennebunk River Well on a seasonal basis for just over four years and with the average levels of PFOS and PFOA at about 50 parts per trillion (which was less than those of the USEPA’s lifelong exposure health advisory), we want our customers to know that we are confident their health was not adversely affected in any way by these trace chemical contaminants.

5/11 – Well, it looks like today will be the final day of the spring flushing season. Yesterday we were able to flush the 31 hydrants that were on the list which brought us back to Granite Point Road. Today we will flush the remaining hydrants in Biddeford Pool starting on Mile Stretch Road, working our way toward Lester B Orcutt and then through 1st-7th streets to wrap things up. Thank you for a wonderful spring flushing season and you can look for us to be back out there again this fall. Hope you have a wonderful weekend and an excellent summer.


5/10 – Yesterday we were able to flush 29 hydrants as planned and make it out to Dyke Road off of Kings Highway. Today, we will finish flushing Kings Highway along the beach and the various side roads that are off of it. This will finish up the flushing in Kennebunkport. From there we will flush the suction side of Granite Point Road as well as Timber Point before going to Bridge Road where we will flush down to Fortunes Rocks. We will then flush all of Fortunes Rocks Road back toward Granite Point Road as well as Sea Spray Drive. If we have any time at the end of the day we will begin to flush out Mile Stretch Road toward Lester B Orcutt. Have a wonderful Thursday and you can look for us to wrap up our spring flushing season tomorrow.


5/9 – Yesterday we were able to finish up all of Wildes District Road, flushing a total of 43 hydrants. This morning as the fog burns off we will be flushing Langsford Road, Mills Road, and Pier Road. From there we will flush Skipper Joe’s Point and Marshall Point before heading over to Kings Highway where we will see how far we can get to wrap up the day. Have a wonderful Wednesday.


5/8 – Flushing another 47 hydrants yesterday brought us all the way to the Walker’s Point on Ocean Avenue. To start this day we will be flushing the rest of Ocean Avenue, Washburn Drive, and Turbots Creek. From there we will be going to School Street near the Crow Hill Tank and we will be flushing back toward Maine Street, which will include all of the side streets. With whatever time we have remaining in the day we will begin to flush Wildes District Road. Have a spectacular Tuesday.


5/7 – I hope you all had a wonderful weekend. Last week we were able to finish up the flushing in the town of Kennebunk and began flushing Kennebunkport, totaling 38 hydrants for the day. Today we will continue to flush our way down North Street as we head toward Dock Square. This will includes Wallace Woods, Oak Street, Church Street, and Maine Street. From Dock Square we will then flush our way down Ocean Street to Kings Highway in the area of the Colony Hotel. If there is time remaining in the day we will flush the rest of Maine Street and see how far we can get down South Maine Street. Hope you have a marvelous Monday.


5/4 – Yesterday, while enduring some early morning humidity and avoiding some afternoon thunderstorms, we were able to flush 44 hydrants. Today we will be flushing Longwood Drive, Rosewood Circle, and Woodhaven Drive, which is the development behind the high school. From there we will be flushing Huntington Commons and Ross Road before heading North on Rt. 1 where we will flush Log Cabin Road and the Cottage Preserve development. With things continuing to go smoothly I anticipate that we may have time toward the end of the day to start flushing River Road to North Street as we begin to make our way into Kennebunkport. Have a wonderful Friday and, if you get a chance, stop by and visit us at the May Day festivities on Saturday.


5/3 – Yesterday we had a wonderful day of flushing around the beach, making it all the way to Oak Street and totaling 48 hydrants for the day. This morning we will finish up the flushing on Sea Road, Sea Garden Circle, Admiral Way, Sea Fields Drive, and Great Hill Road. This will complete the beach area flushing. From there we will be going back to Storer Street and flush both Storer Street and Fletcher Street from Rt 1 back toward the high school, including side roads along the way. As we bring this day to a close we hope to flush Rt. 1 near the Atria and North toward the Hannaford parking lot. This should bring us to a point where we will be able to finish the flushing in Kennebunk tomorrow and move to Kennebunkport. Have a tremendous Thursday.


5/2 – Yesterday, we were able to flush 40 hydrants, flushing all of Sea Road and the first part of Rt. 9 from the Wells town line back to Sea Road. Today, with a taste of some summer heat, we will continue to flush Rt. 9 heading toward Kennebunkport and then proceed down Beach Avenue towards the ocean. Our flushing adventure will hopefully include all of Bayberry Avenue and Boothby Road by the end of the day. Have a wonderful Wednesday.


5/1 – Yesterday we were able to flush the 33 hydrants needed to make it to Christensen Lane in Lower Village. This morning we will be flushing Sea Road all the way to Western Avenue. This will include various side roads like the River Bend Development, Woodside Drive, Ocean View Drive, Penwood Drive, and Madatek Road to name a few. Have a great Tuesday.


4/30 – Last Friday we were able to flush our way in, through, and around the downtown area of Kennebunk totaling 35 hydrants for the day. Today, we are going to be working our way down Summer Street and Port Road heading towards Lower Village. This will include the River Locks Development and should put us in a position where we can flush Sea Road tomorrow. Have a marvelous Monday.


4/27 – Yesterday we flushed another 47 hydrants for the day. This morning we will begin on the north bound side of the turnpike and flush Fletcher Street back to the high school. This will include Old Alewive, Garrison Oaks, Intervale, and part of Ross Road. From there we will be going to Main Street and flush hydrants through the center of town as well as Water Street, Winter Street, Factory Pasture, and part of Summer Street, if all goes according to plan. Have a fabulous Friday and wonderful weekend.


4/26 – Yesterday, we were able to flush another 44 hydrants making it to the other side of the Turnpike on Cat Mousam Road. First thing this morning with the rain coming to an end we will be flushing the Coventry Woods Development off of Cat Mousam Road. From there we will head back to Alfred Road and begin to flush Rt. 35 towards Kimbal Lane. This will include Corning, Independence Park, Alewive Business Park and the Elementary School. Have a great Thursday


4/25 – The first day of flushing in Kennebunk turned out to be a beautiful spring day that allowed us to check off 43 hydrants, bringing us up to the suction side of the Cat Mousam Booster. Today, under cloudy conditions and with rain coming in, we will begin by flushing Brown Street to Clarkdale Road. From there we will be going to Maple Avenue in West Kennebunk, Alfred Road, Thompson Road, Remington Way, Mill Street, and hopefully make it back down Cat Mousam Road to the Turnpike Bridge. Have a wonderful Wednesday.


4/24 – With another 44 hydrants flushed, we brought a close to the spring flushing in Ogunquit yesterday. This morning we will begin flushing in the town of Kennebunk, starting at the Treatment Plant and working our way North along Rt. 1. When we reach the edge of downtown we will turn and flush up High Street to Harriseckett Road. This will include all side roads and developments along the way in both areas. If we have time at the end of the day we may start flushing either Cat Mousam or Brown Street depending on how much time we have available. Hope you enjoy the sunshine today and have a wonderful Tuesday.


4/23 – Last Friday we were able to flush 42 hydrants for the day, making it all the way back to Tatnic Road. Today we will begin a little early and start flushing Shore Road in hopes to make it down to Perkins Cove by the end of the day. This will include Israel Head, Sterns, and Frazier Pasture as well as a few hotels and condos. If at the end of the day we have more time we will begin to work our way further down Shore Road toward the Cliff House. Hope you have a great Monday.


4/20 – With some hard work by our technicians yesterday, we were able to finish flushing the remaining 44 hydrants in the town of Wells. Today, we will begin flushing in the town of Ogunquit, which normally takes about 3 days to complete. We will start today on Berwick Road near our tanks and flush the water mains North along Rt 1, back toward Tatnic Road. This will include the Windward Development, Beach Street, River Road, Ocean Meadows Condos, and Captain Thomas Road to name a few side streets. This will put us in a good position to flush Shore Road on Monday. I hope you have a wonderful weekend as we look forward to more spring like weather next week.


4/19 – We were able to flush 28 hydrants yesterday, which surpassed our expectations and allowed us to finish Atlantic Ave and Webhannet Drive. Today we will be flushing Eldridge Road, Ocean Avenue, Bourne Avenue, the rest of Old County Road, and Royal Heights. This will complete the flushing in the Southern end of Wells. From there we will be going to Sanford Road (Rt 109) and begin flushing toward Spencer Drive. This should put us in a good position to finish flushing in the town of Wells by tomorrow. Once completed we will be heading South to Ogunquit. Have a wonderful Thursday.


4/18 – With the weather acting a little more like spring, and things starting to dry out from the heavy rains we had on Monday, we were able to check off another 41 hydrants as completed. Today we will be flushing the Sea Glass development and a small section of Old County Road before heading back to flush Laudholm Farm. From there the plan is to flush all of Drakes Island by the end of the day. If we have time, we may venture over to Atlantic Ave and start working our way around the beach. We hope you have a wonderful Wednesday.


4/17 – Yesterday was a cold and wet, yet incredibly productive first day of flushing with a total of 45 hydrants for the day. We surpassed our goal of Mile Road and made it to Rt. 9B. This morning we will be flushing 9B, Wells Highlands, Summer Village, Beach Dreams, and the Forest. If we have time toward the end of the day, we may try to get through Sea Glass as well. Have a wonderful day.


4/16 – After a final blast of winter weather we are planning on starting our spring flushing program this morning. We will be heading South from the Treatment Plant along Rt. 1, flushing the various side roads, housing developments, condo units, and business parks along the way. If things go well today, we should be able to make it to Mile Road. Safety is always our number one concern and if temperatures decide to not cooperate we will delay flushing until things warm up. We appreciate your patience with us as we work through this process together. If you have any questions or concerns, please feel free to contact us at 207-985-3385.
