Previously known as the Groundwater Recharge Scientific Study, the study is examining the quality and use of reclaimed water in our groundwater. The Monday, December 9 public workshop will be held from 6:30 p.m. - 8:30 p.m. at 500 Adams Street NE, Olympia.

Like the session in October, the event will provide the community an opportunity to learn more about the study's analysis of the current quality of our local waters, treatment methods, risks of replenishing groundwater with reclaimed water, and the costs of various treatment methods.  

At a meeting of the study's citizen advisory committee on Wednesday, group members heard a report by consultants about the role of temperature in soil aquifer treatment effectiveness.

LOTT staff also reported that the study's peer review panel will begin their work and produce a team report in the third week of January 2014. They will be examining the study's scope of work, make sure the study is scientifically valid and its methodology sound, and provide feedback on the work of the study thus far.

The LOTT Clean Water Alliance (LOTT) will host a public workshop about its multi-year groundwater recharge scientific study on Wednesday, October 23, 6:30 - 9:00 p.m., in the LOTT Board Room at 500 Adams Street NE in downtown Olympia.
The LOTT Clean Water Alliance is designing a study to answer questions about chemicals in our water, what happens to them in the environment, and risks they may pose to our drinking water and other water resources. LOTT staff and groundwater study group citizen advisory group members will be available to answer questions.

The evening format is scheduled as follows:
6:30 p.m. Open House with Information Stations
7:00 p.m. Presentations about the Study Design
7:45 p.m. Discussion Sessions
8:30 p.m. Open House


For more information, call Lisa Dennis-Perez, LOTT public communications manager at (360) 528-5719 or lisadennis-perez@lottcleanwater.org.
LOTT staff has acknowledged they are late in launching a public awareness campaign for its first public workshop on October 23. A second public workshop will be held in December.

A direct mailing about the October 23 workshop will go out this week to those who have previously expressed interest in the study, as well as radio, email and social media announcements, and advertisements in The Olympian newspaper.

LOTT Board Changes Groundwater Study Name, Goal
The LOTT Clean Alliance is a regional water and wastewater treatment facility representing the cities of Lacey, Olympia, and Tumwater and Thurston County.
The LOTT Board of Directors is composed of Cynthia Pratt, chair and Lacey councilmember, Steve Langer, Olympia councilmember, Tom Oliva, Tumwater councilmember, and Sandra Romero, Thurston County commissioner.
At its work session on October 9, LOTT board members agreed by consensus to change the name of the study from the LOTT Groundwater Recharge Scientific Study to its new name, the LOTT Reclaimed Water Infiltration Study.

The reason for the name change came from a recommendation by LOTT staff after they met with three focus groups in late September. The groups were made up of 34 self-selected individuals who were paid to provide LOTT staff their feedback on a series of questions and pictures related to the study.

These participants were paid $75 each at the end of the two hour session held in the LOTT board room. They were asked a series of questions about the study title and terminology such as “compounds of emerging concern” and “reclaimed water” vs. “recharged water.”
Among other comments, they felt the study title was boring, and the term "scientific" was disingenuous. Although some felt an alternative word for "recharge" could be "infiltration," some felt this sounded too militaristic. Others liked the word.
In general, LOTT staff reported that participants felt the topic was not sexy enough to get people's attention, and needed a subtitle and graphic to illustrate its purpose.
Participants were also shown images of household products and asked what words they would use to describe the process of introducing into the region’s groundwater aquifers treated water contaminated with products most of us use everyday, such as shampoo and medicines.
LOTT board member Tom Oliva questioned the new title of the study, and the makeup of the focus groups, saying that the participants did not necessarily align with the demographics of the study. He was also concerned that the words “groundwater” and “scientific” were taken out.
 
After a robust one and a half hour discussion, which included a review of a draft flyer about the upcoming public workshop, the board agreed to the new name change and made minor changes to the flyer.

LOTT board member Sandra Romero said she wanted the flyer to convey to the public that some chemicals that remain in the water may require a higher level of treatment.
"We are not stuck – we’re trying to find the safest level – and way - to infiltrate treated water into our aquifers," she said. She also suggested that the context for why we need to do this be included on the flyer and in workshop presentations.

New Study Goal and Question

In response to a request by LOTT board members to come up with a one-line study goal and a one-line primary study question, the following was offered, and agreed upon:

Goal: Provide local scientific data and community perspectives to help policymakers make informed decisions about future reclaimed water treatment uses.
Primary Study Question: What are the risks from infiltrating reclaimed water into groundwater because of chemicals that may remain in the water from products people use every day, and what can be done to reduce those risks?


Groundwater Peer Review Panel Selected

Ben McConkey, LOTT groundwater study project manager, also presented to the LOTT board members during their work session a near-final list of panelists who are interested and available in serving as peer review panel members to the LOTT Reclaimed Water Infiltration Study.
 
LOTT board members agreed to accept the members, who will be paid a $750 stipend per day of work, with travel and hotel expenses paid by LOTT. McConkey says the panelists will meet about five to seven times over the next three years, and will work about a week before each meeting, attend meetings, and assist with follow-up.

LOTT staff and board members made suggestions to the list for consideration. McConkey worked with the National Water Research Institute to provide a balance of disciplines needed to oversee the study. The Institute made the final selections. The finalists are:

Water Reuse and Public Health/Criteria: Dr. James Crook, Ph.D. Environmental Engineering Consultant, Boston;

Chemistry: Dr. Jennifer Field, Ph.D., professor, Oregon State University

Water Treatment: Dr. David Stensel, Ph.D., P.E., professor, University of Washington, Seattle

Hydrogeology: Dr. Roy Haggerty, Ph.D., retired, Oregon State University

Public Health and Toxicology: Dr. Richard Bull, MoBull Consulting, Richland, Washington.

Full biographies will be posted on the LOTT website.
 
A sixth member of the panel is still being sought to represent a local perspective. Several area tribal representatives have been approached to participate, but no one has come forth.
 
Commissioner Romero urged that the person have experience with the study of compounds of emerging concern, now being called residual chemicals by the study, on fish populations.

Group Advisory Committee, Public Questions Study Purpose, Data

As the study enters Phase II, the framework of the study is falling into four main areas: water quality characterization, treatment effectiveness, risk assessment, and cost/benefit analysis.

The community advisory committee, now composed of 13 members, met again in late July and October 8.  Members continue to receive LOTT and consultant information, and ask questions.
At the Study’s groundwater citizen advisory group meeting on October 8, group members heard more reports about how risk assessments define acceptable levels of exposure to chemicals in the water, and what levels of treatment are used for groundwater recharge in other areas such as the southwest and western states.

Despite the deluge of technical materials provided by LOTT staff and consultants, many members still struggled to define their role - since LOTT has existing and proposed groundwater infiltration projects currently underway - and repeatedly returned to the purpose of the study.
When LOTT staff and consultants showed the group a series of draft workshop posters and asked for feedback, citizen advisory group member and former Olympia mayor Holly Gadbaw was surprised to learn that several properties around the county have already been purchased by LOTT for the purpose of infiltrating treated water into the aquifer.

The potential infiltration sites are: Henderson (12 acres), Rixie Road (32 acres), South Deschutes (49 acres), East Mullen (five acres), and the existing Hawks Prairie infiltration site of 41 acres. The water sampling plan is to study what’s in the groundwater at 20 - 30 domestic wells, and 10 city and community wells in each area.

The Woodland Creek infiltration site in Lacey off Pacific Avenue, currently under construction, is not operated by LOTT – it is an agreement between the cities of Olympia and Lacey. Groundwater monitoring of current conditions at this site has been going on there for about six months.

“This raises a whole bunch of questions…how were these sites chosen?” asked Gadbaw.

Citizen advisory group member Maureen Canny expressed great concern about living in the Hawks Prairie area and wondered if any epidemiological studies are planned for the area. The answer from LOTT staff and consultants was that no epidemiological studies are planned, just toxicological and put it in a risk assessment framework.

The Hawks Prairie recharge site began operations in 2006, and enough time has passed that there would now be interaction with groundwater. Canny took a quick poll of group members and asked if anyone else lived in the Hawks Prairie area, and none did.

“I hope people start thinking about it….If this is the plan, what’s going to happen? Let’s start figuring out the questions,” she asked. She expressed concern that by the time this study is complete, the Hawks Prairie facility will have been in operation for 12 years, and said that should be long enough to determine if there are any concerns, such as an increase in cancer rates.

Citizen advisory group member Lyle Fogg asked staff when people near the proposed infiltration sites will be informed of their locations.

“In my opinion, it should be sooner than later….We should inform them that we’ve already gone down the road this far….” he said.

Karla Fowler, LOTT community relations and environmental policy director, responded that that will be done through a direct mailing in the future, and that the Henderson site is planned to begin operating in 2018.

Citizen advisory group member Ruth Shearer, a retired toxicologist, questioned information provided to the group by Jeff Hansen, lead consultant of HDR Engineering, as she has also expressed at past meetings.
 
The risk assessment to human health that defines an acceptable daily intake level, compared to a maximum contaminant level of exposure, she said, is “based on grossly inadequate testing…these levels are not safe for populations of children with diarrhea, which is quite common, and pregnant women….The acceptable levels of exposure are not the same for all….”

She said that the acceptable daily intake level numbers, as provided, are politically edited, derived from the Environmental Protection Agency’s Reagan administration-era threshold numbers that purposely set the maximum contaminant levels too low due to the cost of treatment.
 
Referring to another piece of literature distributed to the group produced by the WaterReuse Research Foundation, Shearer said the information provided about therapeutic doses were all about skin absorption, not oral intake.

“It was irrelevant propaganda – there are different degrees of skin absorption for each chemical, and it did not address drinking water that may have reclaimed water introduced into it.

“These numbers make me very suspicious of the other numbers….As a toxicologist, I object to ever using the therapeutic dose in risk assessment – that’s why they’re prescription drugs – the therapeutic dose applies to them, but (the study should examine) the effect on normal people….”

There are thousands of unregulated contaminants, but the study plans to study 97 unregulated compounds of emerging concern, or residual chemicals, that are often found in reclaimed water and known to persist in the environment. Contaminants include medicines, personal care products, foods, hormones, and household chemicals.

Dennis Burke, a water system civil engineer based in Olympia, has attended most study committee group meetings and has offered information to committee members during public comment period. He has frequently been critical of the information provided to committee members.

On Wednesday, Burke said he has started a website at www.SaveOurDrinkingWater.org to provide the community alternative information about LOTT and study omissions. He said he'll be adding to it over the next few weeks to feature articles from scientific journals regarding viruses, genetic material, and antibiotics. He said the website will have a comment section and invite contributions.
 
Did You Know?
 
The following questions were offered by LOTT's focus group participants to provide attention-grabbing information about the LOTT groundwater study:

Did you know…
  • Some of the water you use and wash down the drain is treated and cleaned so it can be used again as reclaimed water?
  • Some of the medicines and chemicals from products you use every day may remain in reclaimed water?
  • Some reclaimed water is infiltrated into groundwater, our region’s source of drinking water?

It's The Groundwater: LOTT Advisory Group Still Has A Lot of Questions

It’s the Groundwater: LOTT Advisory Group Still Has A Lot of Questions
 
By Janine Unsoeld
www.janineslittlehollywood.blogspot.com

Reclaimed, recycled, infiltrated.  What do these words mean to you?
In the context of water, those three little words are synonymous. Pose the question to three different people using each one of those words, and chances are you may get three different answers, or, perhaps, puzzled looks altogether. 

After several months and five meetings, the 16 member community advisory group to the LOTT Clean Water Alliance's Groundwater Recharge Scientific Study has wrapped up Phase I of its work.

The group, and the LOTT Alliance, the water utility organization comprised of Lacey, Olympia, Tumwater and Thurston County, will be helping the community understand what these words mean in the months to come. 

Reclaimed water is a form of wastewater management - it's wastewater that has been treated and can be used for a different purpose, such as irrigation. It's a somewhat new concept in the Pacific Northwest, although it has been used for years for a variety of purposes, even for drinking, in California, the Southwest, and other locations in the country. 

The South Sound community is already producing and using reclaimed water. The LOTT Alliance produces Class A reclaimed water using a sand filter technology - up to 1.5 million gallons per day - at its plant in downtown Olympia, and uses it for irrigation. Up to another two million gallons per day is produced at the LOTT plant in Lacey on Martin Way. The reclaimed water produced there uses a membrane bioreactor technology and is currently pumped to the Hawks Prairie reclaimed water ponds and recharge basins where it is infiltrated to replenish groundwater.  Reclaimed water is also being used to enhance wetlands and restore stream flows.

Although the Class A reclaimed water that LOTT produces is continually monitored and tested, there are lingering and emerging questions about our area's unique geography, soil structures, and what is currently in our water system, such as compounds of emerging concern, i.e. pharmaceuticals and personal care products. These are all topics being explored by the LOTT Alliance and the groundwater study advisory group when it comes to the continued and future use of this reclaimed water.

The subject of reclaimed water, and its use for potentially recharging our groundwater aquifers is emotional and fraught with conflicting concerns. It's about community values and its unknown risk on human and environmental health. It's also about money - the cost of processing and treating it to the highest level using the best technology to date, issues around land use and growth, and competing priorities for the use of a precious and scarce natural resource - water.

The Groundwater Recharge Scientific Study

The groundwater advisory group community members applied for their positions and were selected by the LOTT Alliance board of directors late last year. Most group members have demonstrated a steep learning curve. Some have a background or some experience in water issues, public service, and related administrative nuances, such as serving on a board of some kind. Most, if not all, members have exhibited a healthy curiosity and some have asked questions that indicate an ongoing dose of skepticism in LOTT, the process, and the advisory group’s actual role. Some are quite satisfied with the direction of the study, and the information provided thus far. Others, not so much.

Members have received a great deal of information, mostly from LOTT’s perspective, on the latest science regarding basic water/wastewater principals, definitions and explanations of technical jargon, and information regarding the unique challenges facing the South Sound community and its varied water systems.  Public comment has been allowed at each meeting, and members have discussed and reviewed their concerns during meetings. Each meeting has lasted three hours.

The group and LOTT staff has been aided by two consulting firms, Katz & Associates, and HDR Engineering, Inc., to facilitate meetings and help develop materials, presentations, lectures, surveys and public involvement plans.
It is incumbent upon group members to do a lot of their own homework if they want to distill the information provided to them and rise up to ask questions that may counter what it is they are being told.

And they have had a lot of questions: Why is this study being conducted? Why are we here? What are compounds of emerging concern (CECs) and are they currently in our groundwater and/or drinking water? What happens to recharged/recycled/infiltrated water? Where does it go? Is it safe to use this reclaimed water for groundwater recharge? What are the standards now in state and federal law for monitoring CECs? What are the soil types in Thurston County? What do groundwater studies in California have to do with us?
The advisory committee members have experienced what amounts to a college-level crash course in local water reuse issues. It has included science and case-study lectures, Power Point presentations, tours of the LOTT facilities, the creation of public opinion research surveys in the form of interviews with over 50 selected community members and a telephone survey of 400 randomly chosen Thurston County residents, and more. 

So, which words should be used to explain to the community the work of the LOTT Clean Water Alliance’s Groundwater Recharge Scientific Study?
Using the term ‘recharge’ was still causing the group worries during their last meeting, and they considered changing the word to ‘infiltration’. However, in order to stay consistent with word usage in state law, they decided to keep the word ‘recharge’.
Phase II  of the Study - Scoping
At the last scheduled meeting to wrap up their original time commitment to LOTT, staff took an informal round-the-room poll of members to see if they were willing to continue in their positions into Phase II of the study. Reflecting their dedication and interest, almost all the advisory board members agreed to continue on with their commitment to the process.

Phase II of the study will identify the actual activities of the study goals, activities, who will conduct the activities, the actual schedule and cost of the study. A draft public involvement plan has been developed and was discussed. The group will meet again in late July and hold an informational open house for the public on its work thus far in late September. Phase II is expected to be completed by January 2014.
There are several challenges to this multi-year study, as with any long – term regional plan: the diverse levels of interest, knowledge and understanding of water related topics, evolving and varied viewpoints of current science, a lack of regulatory guidelines regarding reclaimed water, and the fact that LOTT is already infiltrating reclaimed water at Hawks Prairie. In fact, the cities of Lacey and Olympia are expected to begin sub-surface infiltration as part of their Woodland Creek Infiltration Project in the Fall of 2013.

Ongoing Questions and Growth in South Sound

Some members of the community, as well as members of the groundwater advisory group, question why groundwater recharge continues while the groundwater study is underway.

Karla Fowler, LOTT Community Relations and Environmental Policy Director, answered some of these questions at the last advisory group meeting:
Why not just discharge more wastewater to Puget Sound, instead of infiltrating reclaimed water? Short answer, there are limits to discharging more to marine waters, and Budd Inlet is already an impaired water system. Fowler discussed two ongoing state Department of Ecology studies that may soon require the LOTT Alliance to put less water into Budd Inlet.

Is this study just a marketing plan to “sell” the public on infiltration because there are no alternatives? Fowler emphatically says no, that LOTT is just trying to understand the science so local decision makers can reaffirm or change what they are doing. She says there are alternatives, but they are different than what has been studied before, such as cleaning the water to a higher level through a reverse osmosis process. 
Why recharge when we live in a place where there is plenty of water? Are groundwater supplies really limited? All our water resources are connected and there is very little clean water available when we need it due to seasonal needs and usage, growth, and related stormwater runoff issues. Our region’s growth is one reason why this study is needed. Increased water demands, and where and how to use wastewater is critical.

Fowler also said using reclaimed water for non-drinking purposes helps directly supplement water supplies. Infiltrating reclaimed water can be used as mitigation to help the cities acquire new water rights. She explained that that’s the reason the cities of Lacey and Olympia are working together on the Woodland Creek Infiltration Project. That project allowed Lacey to acquire new water rights by using reclaimed water to recharge groundwater at the Community Park on Pacific Avenue, east of Carpenter Road.

But, she says, the cities interest in water rights mitigation is not the sole driver for LOTT to infiltrate reclaimed water. LOTT produces reclaimed water and sells it to the cities for $1 a year. It is up to the cities to decide how to use that water, for irrigation or stream flow enhancement, for example. If the cities do not make use of the water, LOTT must have an outlet for it, and that is where the infiltration basins come in. Ultimately, LOTT is tasked with responding to our communities needs for wastewater treatment – existing and future.
Fowler said the groundwater community advisory group has raised a lot of good questions. “We hope to keep chipping away at those questions, providing more answers as we continue to work with you through the next phases of the study,” she said.

The decision to use reclaimed water in our groundwater ultimately lies with the LOTT Board of Directors, composed of four elected officials, one from each jurisdiction, currently held by City of Lacey councilmember Cynthia Pratt (chair), City of Olympia councilmember Steve Langer, City of Tumwater councilmember Tom Oliva, and Thurston County Commissioner Sandra Romero.  
Even before the ultimate decision comes to them, advisory board members have already made several recommendations on how to start educating the community and all Lacey, Olympia and Tumwater city council members and Thurston County commissioners on the issue now.

Tour the LOTT Facility

Ben McConkey, LOTT's facilities coordinator and project manager for the Groundwater Recharge Scientific Study, gave a public tour today of LOTT's Budd Inlet Treatment Plant. The tour provides a fascinating look at the behind-the-scenes work of the facility, which includes seeing a screener with small holes that takes out baby wipes, condoms, tampons, rags, bottles, sticks, leaves and other materials that shouldn't be in the system. Primary and secondary clarifiers and ultraviolet lights further process the water so it can be discharged to Budd Inlet or used for other uses such as irrigation and other non-drinking purposes.
Above: One of the secondary clarifier basins. The Market Center building and the Olympia Farmer's Market can be seen from the LOTT facility in downtown Olympia.
 
At the end of the two hour tour, McConkey answered several questions and thanked today's group of ten people for coming. McConkey, who has a background of nearly 25 years in water and wastewater issues, regularly gives tours to adults and children.
 
Lacey resident Joel Carlson said, "Now I have even more questions. Recycling toilet water into tap water doesn't sound that good, but it makes sense." Carlson said his sister lives in Orange County, California where reclaimed water is treated to the highest level through reverse osmosis. He came on today's tour to educate himself about the water system here in Thurston County.
 
"I've lived here about five years and recently attended a "Sustainable Thurston" teach-in about growth issues sponsored by the Carnegie Group. In order to accommodate growth, we're going to have to look at higher density - I don't see any other way unless you want to see sprawl. The trick is to do it right."
 
"We put a lot of pressure on our water resources," said McConkey. "We use it, dirty it, and throw it away. I'm glad to see the interest - it's complex....One of the passions I have is water and my goal is to help you learn enough to be informed."
 
About the groundwater study specifically, McConkey said, "When I talk about it, I hear a whole spectrum of comments from, 'Why are you bothering me with that?' to very specific concerns. I find that if we don't get everyone's ideas to the best of our ability to help us identify key questions, we won't answer our questions about the best scientific methods and procedures...At least we can inform ourselves of the best options to take. A lot of good ideas can come out of that."

Full Disclosure: Janine Unsoeld was one of 53 members of the community selected to participate in a one-on-one interview to discuss personal perspectives, knowledge and opinions of LOTT, the use of reclaimed water, and general local water issues. My interview was conducted by Patsy Tennyson, facilitator and consultant with Katz & Associates. Comments were anonymously incorporated into a prepared summary report dated May 8, 2013. Participants were not informed or knowledgeable of who else was being interviewed. The full list of interviewed participants can be viewed in the report under Appendix A of the report.

I have also attended every meeting of the groundwater advisory group except one, and have spoken as an individual during time for public comment. My remarks centered around a request for the possibility of televising groundwater advisory board and LOTT Board of Directors meetings for greater transparency and public education and involvement.  These comments and advisory board responses can be viewed in the group’s meeting minutes.
