DEP finds no “man made causes” for river event

This email today from the DEP, saying our river event appears to be  natural circumstances –

Subject: Fish Kill 0ne-pager

As you know, MassDEP has been working with your local responders to investigate a fishkill in the Charles River and Stop Brook.  This started last Thursday afternoon.  We have had staff from our chemical emergency response program, watershed management, resource protection/drinking water, Dept. of Fish  Wildlife , Dept. of Public Health, and US EPA as well as our  mobile field lab checking various locations along the observed impact area.  All tests have come back negative.  We have checked a number of facilities with river discharge permits and found no problems.  Bottom line is that we have found no man made causes for this incident.  In addition, a similar event happened in Bridgewater and similar circumstances were seen in Lakeville.  This all points to a very unusual natural event.

We are keeping on top of this issue.  Call if you have any questions (508) 965-6318.

I spoke to Dino from DEP last night @ 10 and he said they had taken samples from Norfolk and were sending them to the Lab & hoped to have results in the morning of what it might be………he asked if I would go back at first light to see it the problem still existed……..

Went back this morning at 5:15 and it was still noticeable from the bridge on RT27 and I did observe a few dead fish….I called DEP and spoke to Mike Leblanc and reported my observation, he stated they hoped to get the lab reports back but they will be regrouping this morning @ 8 to discuss their next plan of action…….I checked our other bridge locations and the problem was still there but not as noticeable (my opinion)

Before I left yesterday the DEP personnel that were looking at the fish felt they had been dead for 3-4 days

I just got back from Norfolk. Chiefs Kingsbury and Meaney were there also, along with Norfolk, Norfolk prison, state and federal environmental specialists. They expect to spend most of their time in Norfolk and wil contact Chief Kingsbury if they plan to come back to Medfield. Before going to Norfolk, I went down to the Stop River at the Causeway. There was a sheen on that river and an odor, which could have been sewerage or could have been decaying vegetation. A few dead fish were observed in the vicinity of the Sherborn town line. As a precaution the water dept shut down well # 6 this evening and will evaluate the situation in the morning if and when more information is available. They may also add chlorine to the water from well # 6 if they decide to turn it back on. At this point, their is no evidence that whatever is causing the problem on the river has affected the water supply. We draw from about 85′ below ground We will be monitoring the situation and testing the water. We also draw water from the Neponset Watershed and so we do have a backup supply. Since I started writing this Chief Meaney and Kris have arrived and he is responding to a request for information from Theresa Knapp and Kris is talking to Willis and he will notify the other board members.  At this point what is happening is speculation and we will have to wait for testing results from state and federal officials, but it appears that the problem is probably occurring upstream from Medfield (given the testing sites chosen). Precautions have been taken to protect our water supply. If we hear anything more we will let you know right away. Mike

Fish Kill on Charles River

Email from Mike Sullivan –

Fish Kill on Charles River
=================================

We’ve just been notified of a fish kill on the Charles River. There are a large number of dead fish and a blue oily sheen on the Charles River. The worst area appears to be around Route 109. Medfield (Fire Dept) and Sherborn are putting out booms to try to contain it as much as possible Dep is on the way to investigate. given the extent and the location it would not appear that it has anything to do with the State Hospital clean-up.
Kris spoke to DCAM and there is nothing going on at the hospital involving the clean-up. We were notified by our police dept and by DEP and we are notifying Leslee Willits (conservation), Bob MacDonald (treatment plant).
If we hear anything more on this we will keep you advised. We are here until 7:30 tonight anyway so we’ll be around. Mike

Mosquito larvicide spraying 6/13, due to heavy rains

This email from Norfolk County Mosquito Control about new spraying of larvicide –

Subject: Floodplain Aerial Application 6/13/13
Importance: High

Good Morning;

The NCMCD is planning on conducting an aerial larvicide application this Thursday (6/13/13)  to control mosquito larvae hatched from the heavy flooding rains of last Friday night.  We are still in the planning stages, so it is not clear where the exact locations to be targeted are yet, but we will post maps of our proposed sites by Wednesday.  This application is a one day application and will take place over the larger river floodplains.  Since the application will take place over the floodplains, it will be much less noticeable to the public than our spring aerial larvicide that we conduct in April.  Please note that this is not a ‘spray’ to control adult mosquitoes, but is a granular application of a biological larvicide, applied to the wetlands, which is toxic only to mosquito and black fly larvae.

 

If you have any questions or concerns; please contact the office.

Medfield Green

Email from Medfield Green, with a full calendar of events and lots of of good information  –

We  hope you will join us for the next session which will be this Thursday January 24th from 1-2 pm in the Medfield Library Meeting Room.  Please feel free to come if you can, and bring a friend or not.  It is definitely a low-key casual discussion and you are welcome to come once or every time.

Last Thursday we talked about recycling and trash reduction.  Some notes and thoughts are below.

January 24th we will discuss Energy Conservation and etc.  We will share information about the Thermal Imaging done in Medfield by Sagewell, Home Energy Assessments, choosing your electrical energy supplier and other energy saving tips.

January 31st will focus on learning about chemicals in our enviroment and how to keep the bad ones out of our bodies.  Dana Ravech will speak about how to “Clean Green” and we will also talk about Personal Care Products and Lawn Care.

February 7.  to be determined.  What would you like to know?

 

Some notes and tips from our January 17th meeting on Recycling:

Take a few minutes to watch the videos:

The Story of Stuff

The Story of Bottled Water

www.storyofstuff.org

1. Reduce what you are consuming.

Opt out of unwanted catalogs & junk mail (www.catalogchoice.org)

Choose products with less packaging

Can you invest in a few items that will help you reduce waste?  My favorites are a seltzer/soda maker, dry cleaning bag, water bottle, coffee mug, cloth napkins & shopping bags (did you know you can buy a tag for $1 at CVS that will give you $.25 extra bucks everytime you use  your own shopping bag?).

How about sharing yard tools with a neighbor instead of getting  your own for use occasionally?

 

2. Reuse

Visit consignment and thrift shops first.

Get a library book or e-book instead of a new one

And when you are done with something, try to give it a new life.  See the Medfield Green Reuse/Recycle Guide for local places to donate items. http://www.medfieldgreen.org/uploads/M.Green2011_Reuse.3.17.11.pdf

 

Visit freecycle.org and sign up for the local Walpole or Millis groups.  Here you can give away items to folks looking for them.  No money is exchanged.  I’ve had great luck getting rid of latex paint I didn’t need (someone painting murals loved it!), also kids toys and some other household items I didn’t know what to do with.  I always try freecycle first.  It is usually very quick with someone coming to pick up the same or next day.   It’s worth a try to find a home for something that you’d otherwise send to the incinerator.

 

Use the Swap Area at the transfer station.  As the saying goes, “One man’s trash is another’s treasure.”

 

Participate in Medfield Green Day.  It is a one-stop reuse and recycle donation event. We bring together many charities so you can bring your items to a single spot. This year MGDay  will be held on Saturday May 4th from 9 – 12 at the American Legion.  Details for this year will follow but here is a link to the flyer from last year.  http://www.medfieldgreen.org/uploads/MGD_website_flyer_for_website.pdf  If you’d like to know more or to get involved you can contact Donna White at 508-359-0197.

 

3. Recycle

Recycle all you can, especially aluminum & paper.  Both of these are easy to recycle and mean so much to the enviroment if we can keep from deleting new resources.

Make sure you are familiar with the transfer station policies or those of your waste removal company.

Plastic Bags do not go in single stream recycling (even if they have a # on them) but can be recycled at the local grocery stores.  Here is a link to details about which bags can be recycled.  There are so many that can.  www.plasticbagrecycling.org

Textiles are never trash.  Who knew?  There is an afterlife for even the most dilapidated torn and tattered, stained and worn-out clothing, shoes, belts, purses, draperies, cloth shower curtains, pillows & stuffed animals etc.  They must be clean & dry but if they are, don’t throw them out.  Instead, donate them to an organization like Goodwill.    If they are clearly rags or worse (but clean & dry) put them in a bag and mark them rags.  They will get turned into rags or insulation or carpet padding.  And by the way, Goodwill gets paid for this!  If they have some life left, Goodwill will try and sell them at a thrift shop or will sell them to someone who will use them or turn them into rags.  I like donating to Goodwill because I know they start with the products having a chance at reuse locally and then have a complete stream where products can move down the chain but still have a life beyond the incinerator.

 

4. Repurchase

When you have the opportunity, choose something made of recycled materials to close the loop.  If there is more demand for these products, then the price paid for the recycled materials will be higher and more people will benefit.

 

5. Rot

Start a compost pile in your yard.  The Medfield Garden Club often sells bins at a great price. Watch for this!

 

Hope this is helpful.

Single stream recycling contract

Solid Waste Committee is recommending that the Board of Selectmen award the new three year single stream recycling contract to Harvey, replacing Cassella who has provided the services to the town for the last three years.  Mike reports that Harvey came in with a lower price, and that they operate a good looking facility in Westboro.  Cassella apparently offered to match the lower price, once they became aware that they had been out bid.

I reminded Mike that the DEP constantly tells us that we can only achieve the highest recycling rates if we go to a Pay As You Throw (PAYT) system.  PAYT represents a choice of how much inconvenience and cost residents want to accept in order to have the town recycle more, and as a result therefore save more on its solid waste tipping fees (i.e. – the cost to get rid of recyclables is lower that cost to get rid of solid waste).  I have never seen any numbers generated by the Solid Waste Committee on how much we could save by implementing a PAYT system – hopefully they will put those numbers together for the town to consider, now that we have almost completed three years of single stream recycling.

Eastern Equine Encephalitis

From the state website http://www.mass.gov/agr/mosquito/geir_docs/GEIR_MOSQUITO_SPECIES.pdf

=================

1. Eastern Equine Encephalitis
MCP’s in Southeastern Massachusetts, i.e., Norfolk, Bristol and Plymouth Counties, face the greatest threat
from this disease. During major epidemic years, virus activity extends northward from this enzootic focus into
southern New Hampshire and westward into Rhode Island, Connecticut and Central Massachusetts. All projects
except Berkshire County give considerable continuing attention to this potential problem. Upon occasion, projects
may submit mosquitoes to the SLI for EEE virus analysis.
The enzootic foci of EEE are red maple/white cedar swamps. The largest adult populations of the enzootic
vector, Cs. melanura, occurs in or near the localized swamps where this species develops. Most human and horse
cases also occur in the immediate vicinity of these same swamp habitats. Still, at times this mosquito may disperse
114
several miles from its larval habitat (Morris et al. 1980. Nasci 1980. Nasci & Edman 1984) and human/horse cases
occasionally occur in upland areas. This mosquito is unusual in that it overwinters in the larval stage (4th or 3rd
instar). Adults from this generation emerge in late spring (i.e., mid to late May). Two to three summer generations
occur about one month apart, e.g., in late June, July and August, depending on water levels and temperature (Nasci
1980). EEE virus is generally not isolated from this mosquito until late summer. During epidemic years it tends to
be isolated earlier, i.e., beginning in early July, but apparently never from the overwintering generation. The
location of the virus from November to July remains a mystery. Culiseta melanura feeds only after dark and the
vast majority of blood meals are obtained from passerine birds (Nasci & Edman 1981a). This sylvan mosquito
feeds equally at ground level and at higher elevations in the tree canopy. Activity is concentrated just after dark and
just before sunrise (Nasci & Edman 1981b). The morning flight activity peak does not seem to involve
blood-feeding but rather the return to suitable daytime resting sites.
The isolation of EEE virus from the cattail mosquito Cq. perturbans during disease outbreaks (Crans,
personal communication) has focused suspicion on this species at the most likely epidemic vector to horses and
humans. Ae. vexans and Ae. canadensis are two other prime suspects for EEE virus transmission to humans and
horses in Massachusetts. Like Cq. perturbans, they are major pests. Their biologies will be described along with
the other pest species.
A new EEE threat may be developing in New England as Ae. sollicitans, long a known vector in New
Jersey (Crans et al. 1991), was, for the first time, found to be EEE-positive in Connecticut in 1996 (Andreadis
1996). Crans (1991) gave a suggested cycle for EEE transmission to Aedes sollicitans in which Cs. melanura
infected night-roosting glossy ibis, which were then fed upon by Ae. sollicitans while feeding in the salt marsh.
Though the link between glossy ibis and Ae. sollicitans is tentative, there can be no question that Ae. sollicitans is a
potent vector in New Jersey and could be an important vector in Massachusetts as well.

Mosquitoes and beaver ponds

Below is a response from Caroline Haviland regarding species of mosquitos and habitats. Norfolk County started breeching the dam today and will continue for as long as it takes. Hope no one misses Lake Beaver. On the other hand, if they’re really “eager beavers” they may put the lake back next week. Mike Sullivan

Subject: RE: Mosquitoes that inhabit beaver ponds

I apologize for the delay in responding to your e-mail..  My comments during the site visit revolved around habitat changes.  Different species of mosquitoes have certain habitat preferences, i.e. temporary pools, flood plains, plastic containers, permanent water, etc.  In past seasons we’ve treated the flood plains of the Stop River that now seem to be effected by the beaver activity.  Our target species during those applications would be Aedes vexans & other “temporary” or “flood” water species of mosquitoes.  The area upstream of the dam has been converted to “permanent” water habitat and over time, could support permanent water vegetation (ex. Cattails) and attract permanent water species of mosquitoes such as Coquillettidia perturbans.  I’ve included a link below that may better explain this.

http://www.mass.gov/agr/mosquito/geir_docs/GEIR_MOSQUITO_SPECIES.pdf

I apologize for such a short response and am happy to try to provide you with additional information if you wish, mid week next week.  We are working with the Town of Medfield to attempt to lower the water level through a controlled breach of the dam.  We are unsure how active the beaver are and will soon find out how quickly they may rebuild the dam.  We currently do not install water level control devices through dams, but are very interested in learning more about that and may be able to in the future.  Trapping may be employed during the official trapping season.

Subject: Mosquitoes that inhabit beaver ponds

I was out of town last week when the Medfield board of selectman had a meeting about beaver dams in Medfield.  I heard that Caroline Haviland from the Norfolk Country Mosquito Control made a comment about a different species of mosquito inhabiting the beaver pond now that the water level has risen.

I’d like to inquire about document or information about this mosquito, or at least its scientific name so that I may research and learn more about it.

Would you be able to send me any information or at least the name of the species.

Thanks,
