Connecticut residents are invited to join the 40 Gallon Challenge and take on new practices to increase water conservation. The 40 Gallon Challenge is a national call for residents and businesses to reduce water use on average by 40 gallons per person, per day.

As a participant in the challenge, one commits to taking on additionalindoor and outdoor water savings activities. Impactful actions to choose from include: installing a “smart irrigation controller” that adjusts for temperature and precipitation (40 gallons daily savings), replacing an old, non-efficient showerhead with low flow showerhead (20 gallons daily savings), and fixing a leaky toilet and faucet (45 gallons daily savings).

Participation is open to residents and businesses of all states and counties. To sign up, visit http://www.40gallonchallenge.org/and fill out a pledge card.

Quantifying Water Use

Angie Harris“New York City is surrounded by water,” Angie Harris says, “I realized it was a great source of beauty, transportation, and recreation. But it was also contaminated and deeply problematic.” Angie grew up in Queens, New York. She realized water was a crucial resource of concern while an undergraduate at New York University studying environmental sciences.

The interdependent relationship of farming, water and land was also intriguing to Angie. Precipitation and ecology are critical to success in farming. She earned her masters’ degree in environmental science at the University of Rhode Island and worked as a research fellow at the Environmental Protection Agency in the Global Change Research Program. Angie joined UConn Extension two years ago as the Program Coordinator for the Agriculture Water Security Project.

The Agriculture Water Security Project is part of the Natural Resources Conservation Service (NRCS)’s Regional Conservation Partnerships Program and promotes conservation assistance to agricultural producers. The program facilitates Extension’s work in ensuring farmers are thinking about and preparing for drought.

“I serve as a resource for farmers, gardeners, and homeowners to guide and advise them on water conservation and drought preparedness and management. I also serve as a network builder and connect them to other existing resources and organizations,” Angie says. She uses a combination of her education, and personal experience as a full-time farmer for three years in her role on the project. “My mission is to increase the adoption of conservation practices and activities throughout the state.”

Extension is assessing how much water farmers use, and completed a statewide water use survey on irrigation practices and water availability concerns. Next, a pilot metering project at 12 farms tracked their weekly water use for two years. The farms included vegetable, dairy, and nursery and greenhouse operations.

“The farmers kept diligent records and it was inspiring to see how they became scientists and water managers. A curiosity emerged around water use and they demonstrated that they really wanted to know how much water they were using and when,” Angie says.

A key turning point in the water project came at the end of 2016, a serious drought year for Connecticut. UConn Extension hosted a drought listening session for farmers at the Capitol and documented their concerns and ideas in a clear way that was communicated with the state Department of Agriculture and NRCS.

Connecticut developed a state water plan over the last few years. Mike O’Neill, associate dean for outreach and associate director of UConn Extension, served on the planning committee and represented agriculture in the plan’s development.

The next step for the Agriculture Water Security Project was helping farmers prepare drought plans and connecting them to financial assistance from NRCS. A total of 10 projects were provided financial assistance related to developing more robust and secure irrigation infrastructure. Projects included new wells and buried irrigation pipeline.

“We helped a couple of farms access funding to install wells, and it continues to be rewarding to see how pleased the farmers are to have the new resources,” Angie mentions. The Extension project continues to offer irrigation and drought planning resources for farmers.

“I’m excited to see farmers living out their values around land stewardship and food production in thoughtful and creative ways. There is always something that people can do, or a small action they can take to be a mindful citizen,” Angie says. “There is always more to learn, for farmers and residents. For instance, knowing how much water it took to make your jeans or plastic food packaging – it’s important for all of us to continue our learning around the impacts of our actions and consumption.”

Angie led UConn Extension’s initiative around the 40-Gallon Challenge, a national call for residents and businesses to reduce water use on average by 40 gallons per person, per day. It quantifies impacts on the linkage between small actions and water use.

Citizens nationwide are encouraged to participate in the 40-Gallon Challenge by enrolling at http://www.40gallonchallenge.org/. Materials were developed and promoted by Angie and Casey Lambert, a student intern, that quantified water saved by various actions residents can take in their home and yard.

Connecticut is no longer in a drought. But the work of stewardship continues. Angie’s goal is to prepare farmers and residents before water resources become a crisis. By encouraging everyone to simplify, we hone in on the essential needs and ensure successful growing seasons in the years to come.

CT MS4 Guide

maps and other tools are available online for municipalities working with the MS4 guidelines
The CT MS4 Guide is all available online through UConn Extension’s NEMO program.

The CT MS4 Guide website (http://nemo.uconn.edu/ms4) was established to provide a repository for NEMO trainings, materials, tools, and templates that towns can use and modify to meet local needs. Every year, NEMO will also be providing webinars and workshops to help towns and institutions address the more complex portions of the permit.

In the first year of this program, NEMO educated towns on the new requirements through a series of webinar presentations reaching nearly 500 viewers, travelled to 20 town halls to help staff understand and plan for the new requirements, and held a statewide workshop on detecting and eliminating pollution from the stormwater system. NEMO’s Connecticut MS4 Guide (http://nemo.uconn.edu/ms4) is an online repository for guidance, templates, data, and other tools to help communities comply with new statewide stormwater regulations. NEMO also developed templates that towns could use to create a Stormwater Management Plan, an annual report with town progress for DEEP and citizens, and model local ordinance language to respond to requirements in the permit.

Supporting Communities Responding to New Stormwater Regulations

a group works with Amanda Ryan from UConn Extension on municipal stormwater regulations or MS4UConn Extension’s Nonpoint Education for Municipal Officials (NEMO) program is a national leader in developing innovative approaches to help communities address water quality issues. NEMO has been working directly with Connecticut municipalities for 26 years, won multiple national awards, and inspired a national network of sister programs in 33 states. Over the past year, the program has undertaken an innovative new role, as NEMO has become an advisor, helper and cheerleader for the 121 municipalities in the state charged with meeting stringent new stormwater regulations.

In 2017 a new statewide regulation under the Clean Water Act went into effect that significantly changed the way municipalities and state and federal institutions must manage stormwater runoff. The long-awaited update to the State’s Municipal Separate Storm Sewer System (MS4) General Permit is more targeted, specific and extensive than the previous permit, placing a great deal more responsibility on municipalities to reduce the amount of pollution entering waterways via local storm drain systems. Many municipalities were overwhelmed by the challenge of learning, planning, and budgeting for the new stormwater control measures, particularly in the midst of increasingly strained local funds.

In an effort to lessen that burden on towns, the Connecticut Department of Energy and Environmental Protection (DEEP) entered into a unique partnership with the NEMO program, part of the Center for Land Use Education and Research, or CLEAR – a university center based out of Extension and the Department of Natural Resources and the Environment. DEEP is providing support to NEMO through a grant to create and implement a multifaceted assistance program for MS4 towns and institutions throughout the five-year term of the new regulation. The NEMO program hired a new Municipal Stormwater Educator, Amanda Ryan, as a “circuit rider” available to work with any towns or institutions to explain the new requirements and how they can go about complying with them.

This nationally unique approach of providing outreach in partnership with Extension to lessen the burden of complex new regulations appears to be paying off. Last year all of the 121 regulated municipalities submitted their permit registration within the first 6 months of the effective date of the regulation, that was much quicker than under the previous permit without NEMO support for communities. As DEEP staff put it, “When we originally issued the MS4 permit in 2004 it took over 2 years to get all the towns registered. We also issued over two dozen Notices of Violation in 2006 and three Consent Orders in 2008 for towns that either hadn’t completed the registration process (it was a two-step process back then) or hadn’t submitted any annual reports or both. Needless to say, this time around has shown much better success. Frankly, our success in getting such good compliance this time around has to do with you folks (NEMO).” This program has also saved DEEP staff time answering individual questions from towns and enabled the development and dissemination of guidance on some of the murkier permit requirements, two roles that NEMO has taken on in this first year.

From the towns’ perspective, the templates and tools NEMO developed saved them the time and expense of developing those on their own and/or hiring consultants to develop them. NEMO also developed a new MS4 map viewer (http://s.uconn.edu/ctms4map) that will help the towns prioritize where to focus their efforts to most effectively impact water quality. The map viewer identifies water bodies considered impaired by stormwater runoff and areas of high impervious cover. In addition, the towns now have an alternate source to consult for advice on complying with the permit, rather than ask those who are also responsible for judging their compliance with the MS4 permit.

As one town put it, “I would like to thank the Center for Land Use Education And Research (CLEAR) for the assistance it has provided to the Town of East Hartford and other communities in the State with the MS4 program. The information and assistance provided by CLEAR has enabled our Town to save precious resources while complying with the requirements of the MS4 Permit.” – Warren Disbrow, Assistant Town Engineer, East Hartford, CT

The effort is also showing ancillary benefits to the state. One of the data layers in the MS4 map viewer is a new statewide high resolution impervious cover data layer acquired by NEMO to help communities identify high impervious cover areas. A geospatial expert at Esri, the primary GIS software company, found the new layer and combined it with parcel and address data to create a new statewide building address layer. The state Office of Policy and Management (OPM) reports that the new layer saved the state more than $500,000 to acquire on their own.

While just over a year in to this 5-year partnership, the initial results suggest a potentially efficient and cost effective new model for states to launch and manage new environmental regulations. For a small investment, this approach makes it easier for MS4 communities to meet more stormwater requirements and results in a higher level of compliance – not to mention the additional environmental benefits of improving stormwater management practices across the state.

Is there any hope to fix our salt problem? Perhaps…

Another winter has finally ended, and messy roads and salty cars are quickly becoming a distant memory. Where did all that salt go? The millions of tons of deicing salts that get applied to our roads either wash off into local streams, or move into the local groundwater. Yet another research study has recently come out documenting the harmful effects this salt is having in the environment (see UConn Today article). Salt impacts aquatic life in streams, vegetation, and drinking water wells, creating a human health concern. Unfortunately there is no good cost-effective alternative available at this point.

Faced with this situation, New Hampshire decided to attack this problem at the source: reduce how much salt is being applied to the landscape. The Green SnowPro certification program provides municipal public works staff and private contractors with training on how to more efficiently apply deicing salts while still keeping the roads safe for travel. Information is provided on how salt actually works, what the impacts are on the environment, how to calibrate equipment, how much salt to apply given the weather conditions, and how to use anti-icing strategies. Another benefit of the program is that businesses who hire certified applicators receive reduced liability from damages arising from snow and ice conditions, creating an incentive for businesses to hire trained contractors. The New Hampshire Department of Environmental Services has reported that the program is helping to reduce salt application across the state.

Given the recent success of the program in New Hampshire, the program is being adapted here in Connecticut. UConn’s Tech Transfer Center has partnered with CT DOT, DEEP, and UConn CLEAR to pilot the program for municipal public works staff. The pilot session will be later this summer- check the T2 website for details. The goal is to expand the program to private contractors, just as New Hampshire has done.

Although our salt problem will not be fixed overnight, programs like this offer the best hope to tackle this very serious problem.

Michael Dietz from UConn Extension/CLEAR worked with the Tech Transfer Center at UConn to provide a winter operations training for UConn facilities staff. As a result of the training, salt applications were reduced by 3,600,000 pounds, improving water quality, and saving UConn roughly $200,000. Thanks to the UConn winter operations staff and the Tech Transfer Center for helping to make this happen.

Can I Water Vegetables with my Rain Barrel Water?

By Joan Allen

Originally published by the UConn Home & Garden Education Center

Collection of rain water from roofs using rain barrels is growing in popularity because of its many environmental and practical benefits. It can help the environment by diverting water that might contain contaminants away from storm drains and the natural bodies of water that those empty into.  Depletion of well water can be a benefit when this non-potable water is used instead of the tap for things like washing cars, irrigation of plants, and flushing toilets. If you’re on a city/public water system, it can save money to use rain water where you can, too. But is using rain water to irrigate vegetables and fruits safe? Are there contaminants in it that could make people sick? Let’s take a look at what’s been studied.

A few universities in the U.S and abroad have done some work to look at potential contaminants in roof run-off water including heavy metals like zinc, copper, lead and others as well as bacteria such as E. coli and other pathogens. Testing done so far has shown low risk from these, but there is some. And of course, it depends on the type of roofing material, the environment (ie acid rain, urban vs. rural, etc) and possibly other factors. In one study, most of the metals tested the same in rain barrel water as in rain water before it hit the roofs, so little to no concern there. One exception was zinc, and elevated levels could lead to build up of this element in soils. At high enough levels, this can cause injury to plants and those plants should not be consumed (1). Monitor for this by having the soil tested.

While risk appears to be low, there were a few samples in studies (1, 2) where E. coli or total coliform bacterial levels exceeded official standards for some uses. Rain barrel water should NEVER be used for potable purposes such as drinking water, cooking or washing. Where do the bacteria in run-off come from? The main sources would be fecal matter from animals such as squirrels and birds that land and move around on the roof.

But if you’d like to water your vegetable garden with rain barrel water, are there ways to do it safely?

Dr. Mike Dietz, Assistant Extension Educator at UConn with expertise in water management recommends “not using roof water on anything leafy that you are going to eat directly. It would be OK to water soil/plants where there is no direct contact”. This is consistent with recommendations from other experts who suggest applying the water directly to the soil and avoiding contact with above-ground plant parts. An ideal set-up would be to hook up a drip irrigation system to your rain barrel(s). Pressure will be improved when they are full and if they are elevated. A full rain barrel can be pretty heavy, at about 500 lbs. for a 55 gallon unit, so make sure they are on a solid and stable base such as concrete blocks.

If possible, and this is done in larger collection systems automatically, don’t collect the ‘first flush’ of water off the roof. This would be the first few gallons. In a ¼” rainfall as much as 150 gallons can be collected from a 1000 ft2 roof surface (3). The first water to run off tends to have higher concentrations of any contaminants because of them building up on the roof since the previous rainfall event.

Another more practical way to minimize risk of pathogen/bacterial contamination is to treat the collected water with bleach. Rutgers University recommends treating 55 gallons of water by adding one ounce of unscented household chlorine bleach to the barrel once a month (or more often if rain is frequent). Allow this to stand for 24 hours before using the water for irrigation so the bleach can dissipate.

Apply collected water in the morning. Wait until leaves dry in the sun before harvesting. Ultraviolet light from the sun will have some disinfecting effect.

It is recommended to have the rain barrel water tested for E. coli. Be sure to follow the testing lab’s instructions for collection, storage and time sensitivity of the samples.

Thoroughly wash all harvested produce. In addition, you should always thoroughly wash your hands with warm, soapy water after they are in contact with collected water.

In summary, there are risks to using collected rain water for irrigation of food crops. In most cases, the risk appears to be low, and using the above sanitation practices can reduce risk.

What Do You Do After You Scoop?

By David Dickson

On my drive home last week I saw two of my neighbors walking their dogs. One of the dogs had just done his business and the owner dutifully scooped it up with a doggy doodie bag dangling from the dog’s leash. Excellent, I thought, he knows that dog poop left on the street can be carried by stormwater into our storm drain and then pollute our waterways with bacteria. As a water quality educator, I was pleased to see the “scoop the poop” message was getting out.

However, my neighbor then proceeded to drop the doodie bag directly into the storm drain! So, there is still work to do. Once you scoop it, you need dispose of it properly – either in the garbage or flushed down the toilet (minus the plastic bag). Not carry it directly to the storm drain.

This has gotten me to think more about how we educate the public about the impacts of common everyday activities on our lakes, streams and rivers. Under our new state stormwater management regulations (a.k.a, the MS4 permit) towns are required to educate their citizens on the impacts things like pet waste and fertilizer have on our waters when transported to our storm drain system. However, if towns are going to invest/spend their limited time and resources on public outreach, it makes sense that they ensure they are as effective as possible at conveying the whole message, while also keeping it simple.

CLEAR’s NEMO program is helping communities to identify ways to get these messages out. Our online MS4 Guide has examples of public outreach materials towns can use, but there are other resources as well. URI’s Stormwater Solutions program has some great public outreach materials on scooping and trashing pet waste, including cartoons like the one above. The EPA has a nice stormwater outreach”toolbox” with examples from around the country searchable by topic or media type.

Still, many of these focusing on the scooping, which at least in my neighborhood (and I’m guessing in yours) is only half the battle. So choose carefully.

Maybe someone will come up with a cute phrase that tells people what to do AFTER they scoop. “Scoop the poop and then place it in the proper receptacle” doesn’t exactly roll off the tongue.

Stormwater Research from Extension

stormwater running into a street drain

Our UConn Extension educators working in land use, and the environment have recently published two articles:

Extension Educators Mike Dietz and Chet Arnold have an article, Can Green Infrastructure Provide Both Water Quality and Flood Reduction Benefits?, in the May issue of the Journal of Sustainable Water in the Built Environment. You can read the article online at: http://s.uconn.edu/476

The UConn CLEAR NEMO team recently wrote an article on our State of LID in Connecticut study that was published in the Watershed Science Bulletin. The study looked at what is being required for stormwater management practices by Connecticut municipal land use plans and regulations. Much of the leg work for the study was carried out by our Extension intern a few years ago. The article can be read online at: http://s.uconn.edu/477.
