Let them tell you about the birds, and the bees, and the bats …

Friday, January 20th, 2012

Mark your calendars for Saturday, Feb. 18. The Longswamp Township Environmental Advisory Council will host a backyard wildlife workshop at TEK Park, 9999 Hamilton Blvd, Breinigsville, on the first floor.

The theme — Birds, Bees, and Bats Too! Why We Need Our Winged Friends — will be broken down into three sections:
 Steven Saffier of the Audubon Society will discuss the creation of bird habitat and sustainable landscaping, identifying birds, the Great Backyard Bird Count,  and Bird Town  programs.

Dan Mummert of the Pennsylvania Game Commission will talk about bats, the effects of White Nose Syndrome, how to handle bat conflicts in the home, and bat conservation efforts.

James Griesemer of Griesemer Beekeeping will discuss the benefits of honeybees and our native mason bees; the basics of keeping honeybees, and what we can do to help our pollinators.

Although the event is free, you must RSVP by Feb. 11 by sending an e-mail to Longswampeac@gmail.com or by calling or texting Cathi at 610-216-7976. Provide your full name and contact information. Registration will be confirmed by e-mail or phone.

Hurry, because registration is limited to 200. In case of inclement weather, the rain date is Sunday, Feb. 19.

Polluted runoff has far-reaching consequences

Thursday, December 22nd, 2011

Over the past few months, we’ve written about buffer zones and source water protection in an attempt to outline the importance of keeping our water supply clean. A recent study by the University of Georgia, however, drives home the fact that the effects of polluted water reach far beyond local watersheds. Researchers there found that a combination of excess atmospheric carbon dioxide and fertilizer runoff carried by the Mississippi River to the Gulf of Mexico is increasing the acidity of Gulf waters.

The study shows that the mix is proving deadly for marine life. The fertilizer causes algal blooms that soon die, sink, and decompose, releasing carbon dioxide that reacts with the seawater and creates an acid. Compounding the problem is carbon dioxide released by fossil fuels, which is absorbed at the ocean’s surface and also forms an acid. The increased acidity is too much for the ocean to neutralize, and marine life such as oysters, clams and corals have a much harder time forming and maintaining their exoskeletons and shells. Scientists say that at this rate, by the end of the century these sea creatures won’t be able to create shells or structures at all.

UGA Distinguished Research Professor of marine sciences James T. Hollibaugh says the effects of the deadly duo will be widespread:  “Many of our fisheries resources, especially shellfish, are concentrated in areas where rivers discharge onto the coast, like the northern Gulf and the East China Sea, and thus are at risk. And of course there are likely ramifications for fish and animals further up the food chain that depend on these same shellfish for food.”

If the problem is cropping up in the Gulf of Mexico, it’s a sure bet it’s also happening here.  Locally, the Lehigh River flows into the Delaware River in Easton. The Delaware then spills into the Delaware Bay, known in part for its blue crabs, oysters, clams, and shrimp.

So what can you do to help? If you haven’t already, establish a buffer zone to protect waterways from polluted runoff. Prevent waste from pets and livestock from being washed into streams and rivers. Eliminate or reduce the use of chemical fertilizers. And take a look at the Delaware River Basin Commission’s Web site to see what else can be done to protect the bay.  If everyone does their part, we can preserve our rivers, streams, oceans and drinking water for future generations.

Get ready, winter’s on the way!

Thursday, December 15th, 2011

Old Man Winter will be here in just a few days — along with frigid, pipe-bursting  temperatures. Before the mercury drops any further, take some time to winterize your home.

Start by examining water pipes. Insulating pipes — especially any that run along an outside wall or are outside the residence — can save money by preserving hot water and prevent costly problems by keeping those pipes from freezing. For pipes that run outside a residence, adding a wrapping of heat tape is also recommended. Just ensure that the tape is UL listed and is installed according to the manufacturers’ instructions to avoid problems. (In some cases, insulating your pipes can net you state or federal tax credits. Check here to find out if you qualify.)

Make sure to turn off water to all outside faucets (there should be an indoor shutoff valve; if not, it’s a good idea to have a plumber install one), then drain them by opening the valve outside. You may want to consider adding a faucet cover as an additional measure of protection (especially if there’s no way to shut the water off). If you’re winterizing a vacation home, take a look at this handy checklist).

Next, check the caulking around your windows. If it’s old and cracked, falling out, or just plain nonexistent, replace it. This will help to keep out chilly drafts, moisture, and even insects.

You may also want to consider replacing older windows with energy-efficient models that can block harmful UV rays and keep outside temperatures where they belong: outside. A cheaper alternative may be installing storm windows, which will provide an extra layer of insulation and protection when the winter winds blow. An even cheaper solution is a window insulation kit, available at hardware or discount stores.

If there are drafts sneaking under your doors, there’s an old-time tip that works great and costs nothing: Place a rolled-up bath towel against the bottom of the door. For a more stable fix, attach a vinyl door sweep.  They’re held in place via an adhesive backing, so no tools are required, and they cost just a few dollars.

If you don’t have one already, consider installing a storm door, which will go a long way toward sealing out drafts. There are plenty of Energy Star-certified models to choose from.

You’ll also want to check for gaps in spots where different building materials meet: chimneys, foundations, and areas where pipes or wiring enter the home. For an easy, DIY test, hold a lighted stick of incense a few inches away from interior walls and move it slowly from one end to the other: If the smoke wavers, it’s indicating an air leak.

Next, make sure your furnace is up to the task by installing a new air filter and having the unit inspected by an HVAC professional.

Finally, consider adding more insulation to the attic and inside exterior walls. It’s one of the most cost-effective ways to save money year-round, and in most cases, it also qualifies for a tax credit.

 

 

Turn over a new leaf: composting beats burning

Monday, November 28th, 2011

Fall: It’s the time of year when trees put on their coats of many colors; apples fill the bins at roadside stands, carved pumpkins decorate porches, and thick, cough-inducing smoke fills the air.

It’s not hard to figure out which of these things doesn’t belong, but for some, burning leaves — despite regulations banning the practice in many areas — seems to be an Autumnal rite of passage. There are much better ways to dispose of your leaves, however; ways that don’t fill the neighborhood with smoke. Leaf burning is a health risk, especially to those with sensitive lungs, such as children and the elderly. It can induce asthma attacks, cause headaches and nausea, and is a frequent culprit in brush and structure fires. It also adds more pollution to the atmosphere and wastes some great garden nutrients. So quit burning (and encourage your neighbors to do the same) and start putting your leaves to good use.

If you have room, the easiest option is to rake them into a pile and let them decompose in an out-of-the-way part of your back yard. Chicken wire can be used to make a handy enclosure to keep them from blowing around. Pile them up inside, and let nature do the rest. It takes about two years to turn the leaves into an excellent soil amendment called “leaf mold.” Keeping the leaf pile moist and occasionally turning it over will help speed the process. Multiple piles will allow you to rotate your “crop” next fall. The end result can be used as mulch, as a peat moss replacement, and a number of other soil conditioners. (If you’d like to learn more, the folks at Rodale’s Organic Gardening magazine have a wealth of information on composting leaves.)

If that’s not an option, many municipalities offer curbside leaf pickup; the information is usually listed on their Web site or available via a quick phone call. Leaves (as well as grass clippings and other yard waste) can also be taken to a number of compost facilities in the greater Lehigh Valley area, including Lehigh County’s, the Saucon County Compost Center, a number of sites in Allentown, the Bethlehem Compost Center, and more. Check with your municipality to find one nearby. Oh, and don’t forget to ask around your neighborhood, too – it’s quite possible someone is looking for more materials to add to their compost pile.

Whatever you do, please, don’t burn ’em. Mother Nature — and your neighbors  — will thank you.

Reducing global warming, one meal at a time

Wednesday, November 9th, 2011

We want your table scraps!

A recent food-waste disposal study has found that using an in-sink garbage disposer can help reduce global warming. According to a write-up about the study, “a community of 30,000 households could avoid the equivalent of more than 2,000 tons of carbon dioxide emissions if most of its food scraps went through a disposer to a wastewater treatment facility instead of to a landfill. That is akin to eliminating 4.6 millions of miles of car traffic.”

That’s a lot of waste that’s not getting wasted!

Because the Lehigh County Authority accepts only domestic strength wastewater and wastewater from food manufacturers, the solid waste, or sludge, that’s left behind after treatment is of a high enough quality that it can be recycled as fertilizer. So using a garbage disposer to eliminate your food waste — instead of tossing it in the trash — means it’s getting a second life instead of lining a landfill. (For some of our customers, another option is composting.)

In the future, table scraps could also help power our wastewater treatment plant. We’re studying the benefits of converting our treatment plant so that it can produce its own electricity via biogas. When solid waste is treated, one of the byproducts is methane — the major component in natural gas. Using methane to power an electrical generation system may have some great financial and environmental benefits. We’ll keep you posted on the results of the study.

In the meantime, put that garbage disposer to work for the environment!

Check for a toilet leak on the cheap

Monday, October 24th, 2011

Did you know that a leaking toilet can waste up to 200 gallons a day? That’s an expensive problem! Fortunately, fixing it can cost as little as $8.

To find out if a toilet is flushing your money down the drain, remove the lid and add a few drops of food coloring — dark colors work best — to the tank. Wait about a half-hour (don’t flush!), and then check the bowl. If there’s food coloring in the bowl, there’s a leak.

In most cases, an easy-to-install toilet repair kit (available at hardware stores and many retailers that carry home improvement items) will fix the problem. Just make sure the kit is compatible with the toilet.

If your toilet is older, consider replacing it with a WaterSense model. According to the EPA, the switch could save a family of four more than 16,000 gallons per year.

Keeping it clean (and green)

Friday, August 19th, 2011

If you want to lead a more “green” lifestyle, one of the easiest places to start is the cabinet where you keep cleaning supplies.

Though it may seem counter-intuitive, many household cleaners contain highly toxic substances. Examples include formaldehyde, which can be found in furniture polish and is considered a carcinogen by the World Health Organization; diethylene glycol, a poison that causes kidney failure and is found in window cleaners; and perchloroethylene, a carcinogen and central nervous system depressant found in carpet and upholstery cleaners.

That’s the bad news. The good news is that there’s a host of alternatives available that are not only environmentally friendly, but also much easier on your wallet. Some of them — such as vinegar, baking soda, cornstarch and lemon juice — are probably already be in your pantry. And they were being used to effectively clean the house long before the advent of ready-made chemical products.

Let’s start with window cleaner. A mixture of vinegar and vegetable-based liquid soap does the trick well. The folks at care2.com suggest this recipe: combine 2 cups of water, 1/4 cup of white distilled vinegar, and up to 1/2 teaspoon of liquid soap or detergent in a spray bottle. The soap, ironically enough, is needed to cut through any residue left behind by previous chemical window cleaners. After using this mixture a few times, you should be able to switch to straight five percent vinegar.

To polish furniture, mix a cup of mineral oil with three drops of lemon (or orange) extract (not juice). To remove excess polish, sprinkle with cornstarch and buff with a soft rag.  And while we’re on the subject of cornstarch, it can also be used to clean carpets and rugs: sprinkle it, then let it sit for 30 minutes before vacuuming. It will draw out odors and dirt like a charm.

For stains, white vinegar or lemon juice work to get out many substances (Wholeliving.com has a comprehensive list of natural stain removers for different applications).

Ready to clean the bathroom? Make a paste of baking soda — three parts baking soda,  one part water (or liquid soap) — to scrub toilets, tubs and sinks. Spraying them down with an undiluted solution of five percent white vinegar (which is how it’s usually sold) will significantly reduce the amount of bacteria, mold and germs. Although it’s useful as an antimicrobial agent — tests requested by CBS’ 48 Hours have found it to be 99.9 percent effective against bacteria — keep in mind that it’s not recognized by the EPA as a disinfectant.

Vinegar can also be used as a general cleaner around the house; it’s a good  for countertops, tables, and other surfaces.  Never use it on marble, however, and make sure to dilute it before using it on grout, as it can eat away at the sealer.

Baking soda is another essential ‘green’ house cleaner. A small bowl of it will reduce odors in the pantry, refrigerator and freezer, and it can be used to deodorize trash cans. A mix of baking soda and water will also remove odors from food containers if it’s allowed to soak overnight. Much like cornstarch, it can also be used to get your carpets smelling fresher.

Just remember to properly dispose of any chemical cleaners you won’t be using anymore.  Never flush them down the drain, where they’ll end up polluting the water.

Garden overflowing? Freeze that food!

Thursday, August 11th, 2011

Harvest time is, arguably, the best part of growing your own fruits and vegetables. You’ve used compost to enrich the soil; kept weeds down by mulching, and used your rain barrels to irrigate the plants. Now it’s time reap what you’ve sown. But when everything starts turning ripe around the same time, a trip to the garden could seem like a scene from ‘Attack of the Killer Tomatoes.’

Have no fear. Taming that plethora of produce isn’t as tough as it looks.

For years, canning has been the go-to solution for home gardeners. Your mother probably did it, and your grandmother, and her grandmother, too. The upside of canning is that it provides a reliable, long-term solution to the problem of preserving your harvest. The downside is … well, there are several downsides, actually. It’s messy, it’s time consuming, and the process compounds the dog days of summer by adding a lot of heat and humidity to your kitchen.

That’s not to say canning should be taken off the table. It’s a tried-and-true method of storing food, and although it’s labor-intensive, the payoffs are well worth the time. If you want to learn more, the USDA has collected some great information here. But if time’s of the essence, keep your cool by freezing instead.

Freezing is one of the simplest ways to store food. Preparation is quick and easy, and there’s no need for specialized equipment. Pick up some freezer bags, sugar, salt and, if you’re concerned about fruit discoloration, ascorbic acid, and you’re ready to go. Most fruits and vegetables can be frozen in just a few minutes’ time. And when it’s the middle of winter and you want some of those peppers that tasted so good this summer, you need go no further than your freezer.

Here are some quick recipes from the Penn State Cooperative Extension to get started (note that their site suggests never freezing more than 2 pounds of food per cubic foot of freezer capacity per day):

 Tomatoes

Select firm, ripe tomatoes with deep-red color. Wash and dip in boiling water for 30 seconds to remove skins. Core and peel. Freeze whole or in pieces. Pack into containers, leaving 1-inch head­space. Seal and freeze. Use only for cooking or seasoning since tomatoes will not be solid when thawed. Note: Cooking or stewing tomatoes provides better texture and flavor.

Strawberries

Homegrown varieties are best for making jams and freezing

• To make a syrup pack: Dissolve 3 cups of sugar in 4 cups of water. Add 1 cup of this syrup per quart of prepared fruit.

• To make a dry sugar pack: Mix 2⁄3 cup of dry sugar per quart of prepared fruit.

• To make a dry pack: Omit sugar.

To package: Fill pint- or quart-size freezer bags to 3–4 inches from top, squeeze out air, seal, label, and freeze. Before freezing, bags may be inserted into reusable, rigid freezer containers for added protection against punctures and leakage. If using rigid containers, allow 1⁄2-inch headspace for dry pack and 1-inch headspace for syrup pack berries in quarts.

Prepared berries can also be individually quick frozen (IQF) first on a tray and then packed into containers as soon as they are frozen. IQF berries may be used partially thawed as a snack.

 Peppers

Bell or Sweet Peppers preparation: Select crisp, tender, green or bright-red pods. Wash, cut out stems, cut in half, and remove seeds. If desired, cut into 1⁄2-inch strips or rings.

For longest shelf-life, water-blanch halves for 3 minutes and strips or rings for 2 minutes. Cool promptly, drain and package, leaving 1⁄2-inch headspace. Seal and freeze. For crisper texture, package raw, leaving no headspace. Seal and freeze.

 Hot Peppers preparation: Wash and stem peppers. Package leaving no headspace. Seal and freeze.

Lawn brown? Don’t let it get you down

Tuesday, August 2nd, 2011

With summer heat making even your thermometer break a sweat, many homeowners are taking to watering their lawns more frequently.

The trouble is, that’s not always the best thing for it.

For starters, frequent watering encourages grass to develop shallow roots – not the deep-reaching roots that help to create a healthy lawn capable of surviving drought, high heat and lots of activity. Another problem is that too much water will keep the roots wet, making your lawn more susceptible to disease and insect damage. And overwatering also leads to increased runoff, which can carry away soil, fertilizer, chemicals and pet waste, polluting the water supply.

So what’s a grass-lover to do?

A brown lawn doesn't mean it's dead, just dormant.

In most cases, you can simply let your lawn go dormant.  It will turn brown, but that doesn’t mean it’s given up the ghost. It just means the grass is preserving itself by storing its energy in its roots and temporarily giving up on the blades — a perfect tactic during hot, dry weather. An established lawn will be just fine if it doesn’t get water for several weeks (although newly seeded areas have very different needs). When cooler weather rolls around, new blades will shoot up.

It’s important to remember that, with the exception of rain, you shouldn’t water during this dormant period, as that will stress the lawn by encouraging it to ‘wake up’ too soon – sort of like having your alarm clock go off several hours early.

If dormancy isn’t an option, there are a few ways to ensure a lawn isn’t being overwatered. The rule of thumb for a healthy, established lawn is to provide about 1 inch of water each week, applied in one session. That number varies based on the weather and the type of soil — heavy, packed soils require less water; sandy, arid soils need more.

Quick tip: Place an empty 12 oz tuna or cat food can under a sprinkler.  When it fills up, that’s about an inch, and the lawn’s had enough.

Common sense is key: If rain’s in the forecast, hold off on watering until you see if the weather report holds true, and then use a rain gauge to figure out how much has fallen. If it’s under an inch, do the math to figure out how much more is needed. And always water in the morning to reduce evaporation and give the lawn a helping hand through the heat of the day.  Watering in the afternoon wastes much of the H2O through evaporation, and watering at night encourages disease.

Finally, give the lawn – and your mower – a break. Cut the grass no lower than 2”, and avoid frequent mowings.  You’ll save energy, reduce wear and tear on the machine, and help the lawn to conserve its water supply.

Looking for more information on keeping your lawn healthy? Take a look at a few tips from the USDA, and be sure to read our earlier blog on water conservation.

Source Water Protection is everyone’s job

Tuesday, July 19th, 2011

On Thursday, June 23, Lehigh County Authority and the City of Allentown hosted a joint presentation to explain our respective
plans to protect our drinking water supplies from contamination. The presentation summed up an exhaustive study of where our water comes from and how it can be affected by any number of factors, including runoff from development and residential areas; industrial and agricultural byproducts such as chemicals or fertilizers; and runoff from roads.

The study area included the City of Allentown, the townships of Weisenberg, Lowhill, Upper Macungie, Lower Macungie, Salisbury, and South Whitehall, and the boroughs of Alburtis and Macungie in Lehigh County, and Longswamp Township in Berks County.

Utilizing results from the study, LCA and the City of Allentown are developing a plan to protect our sources of drinking water. This has numerous benefits, not the least of which are the protection of public health, promotion of sound land-use planning, and preservation of the environment. Some of the benefits are also financial – for example, the reduced cost of water treatment. A recent EPA study estimates that, on average, every $1 spent on source protection saves $27 on water treatment.

The plan calls for dividing the area into three zones. The most protective zone, Zone I, is a circle around each well with a radius ranging from 100 to 400 feet (DEP, 2005). The second most protective zone, Zone II, represents the 10-year time of travel – the area from which groundwater has a high probability of reaching the well in fewer than ten years. The Zone III protection area is much more extensive, as it encompasses nearly 50,000 acres and includes multiple municipalities in Lehigh and Berks counties.

Some of the steps Allentown has taken as part of the plan’s implementation include:

  • A street sweeping and litter pick-up campaign.
  • The removal of more than 9,000 tons of debris and leaves from city streets.
  • The removal of more than 3,000 cubic feet of debris from storm water inlets and 174 cubic yards of debris and sediment from safety grates and surrounding areas.
  • Implementation of S.W.E.E.P. (Solid Waste Education and Enforcement Program). So far, more than 7,000 violation tickets have been issued to enforce the city’s litter and trash ordinances.
  • The completion of a buffer zone project near Cedar Beach Park.

Here at LCA, we’ve been busy, too. Here are just a few of our related projects:

  • An ongoing leadership role in coordinating HydroMania events for the Lehigh Valley.
  • Participating in Emmaus Watershed Day.
  • Coordinating and sponsoring a household hazardous waste drop-off program.
  • Initiating a rain barrel program.
  • Offering “green ideas” on this blog and our Facebook page.
  • Educating homeowners and businesses about their important role in source water protection.

It’s important that all of us understand the impact we have on the water we drink. Please take some time to learn more about our work to keep our water supplies clean, and what you can do to help:
