How Green is My...Lake?
For many New Rochelle residents who live near Beechmont Lake, the sight of bright green algae blanketing the water is a painful reminder of the true cost of environmental damage.
Westchester County and New York State recently pioneered environmental legislation intended to reduce unsightly green algae blooming across our lakes by limiting the use of phosphorus-containing fertilizers. But the new laws, some of which go into effect just a few months from now, may be too little, too late.
Mayor Noam Bramson lives near the lake. “I live only a few hundred feet from Beechmont Lake and observe its condition with distress and frustration on a daily basis. The ecology of the lakes and waterways within New Rochelle — and throughout our region — is stressed by a variety of factors. Excess nitrogen and phosphorus, for example, makes its way into lakes from fertilizer run-off and a variety of other sources.”
The website of the New York Public Interest Research Group (NYPIRG) notes that “Phosphorus (P) occurs naturally in living things and soil, but when too much enters streams and lakes it stimulates the growth of algae and results in an algae bloom.” It is estimated that just one pound of phosphorus can produce up to 500 pounds of algae.
According to the New York State Department of Environmental Conservation (DEC) , focusing on ways to limit phosphorus in lawn fertilizers is important because most soils in the state already contain sufficient phosphorus to support turf grass growth without additional phosphorus in fertilizers. In addition, phosphorus in lawn fertilizer can account for up to 50% of the soluble phosphorus in storm water runoff from lawn areas.
New rules on phosphorus in fertilizers will go into effect January 2012, including a ban on using lawn fertilizer between December 1 and April 1 and a ban on the use of fertilizer containing phosphorous unless you are just starting a new lawn or unless a soil test actually proves your lawn lacks adequate phosphorus.
How can you tell if your fertilizer is phosphorus-free? All fertilizer bags list 3 numbers on the label that are the percentages of 3 key nutrients in the product, always listed in order as Nitrogen ( N), Phosphorus ( P) and Potassium (K). So you might see a bag with 20-10-20, for example, meaning 20% Nitrogen; 10% Phosphorus, and 20% Potassium.
Aerators For Streams - News
One step that has been taken by other communities is for neighborhood groups to work with city government to consider the installation of aerators that might partially address the problem. The aerators that were installed in the lakes in front of the
Efforts to control the algae and improve water quality have included a chemical alum treatment and other initiatives such as dredging of feeder streams and replacement of aerators that increase oxygen in the lake, and state officials are "cautiously
The system can provide enough electricity to supply about one-third of all Musco's needs and is powering aerators at the facility's wastewater holding ponds. At full potential, perhaps by year's end, the system should meet about half of the plant's
Reduce Hot Water Use for Energy Savings « Better Water Heaters
You can lower your water heating costs by using and wasting less hot water in your home. To conserve hot water, you can fix leaks, install low-flow fixtures, and purchase an energy-efficient dishwasher and clothes washer.
Fix LeaksYou can significantly reduce hot water use by simply repairing leaks in fixtures—faucets and showerheads—or pipes. A leak of one drip per second can cost $1 per month.
If your water heater’s tank leaks, you need a new water heater.
Install Low-Flow FixturesFederal regulations mandate that new showerhead flow rates can’t exceed more than 2.5 gallons per minute (gpm) at a water pressure of 80 pounds per square inch (psi). New faucet flow rates can’t exceed 2.5 gpm at 80 psi or 2.2 gpm at 60 psi. You can purchase some quality, low-flow fixtures for around $10 to $20 a piece and achieve water savings of 25%–60%.
ShowerheadsFor maximum water efficiency, select a shower head with a flow rate of less than 2.5 gpm. There are two basic types of low-flow showerheads: aerating and laminar-flow. Aerating showerheads mix air with water, forming a misty spray. Laminar-flow showerheads form individual streams of water. If you live in a humid climate, you might want to use a laminar-flow showerhead because it won’t create as much steam and moisture as an aerating one.
Before 1992, some showerheads had flow rates of 5.5 gpm. Therefore, if you have fixtures that pre-date 1992, you might want to replace them if you’re not sure of their flow rates. Here’s a quick test to determine whether you should replace a showerhead:
Place a bucket—marked in gallon increments—under your shower head. Turn on the shower at the normal water pressure you use. Time how many seconds it takes to fill the bucket to the 1-gallon (3.8 liter) mark.If it takes less than 20 seconds to reach the 1-gallon mark, you could benefit from a low-flow shower head.
FaucetsThe aerator—the screw-on tip of the faucet—ultimately determines the maximum flow rate of a faucet. Typically, new kitchen faucets come equipped with aerators that restrict flow rates to 2.2 gpm, while new bathroom faucets have ones that restrict flow rates from 1.5 to 0.5 gpm.
Aerators are inexpensive to replace and they can be one of the most cost-effective water conservation measures. For maximum water efficiency, purchase aerators that have flow rates of no more than 1.0 gpm. Some aerators even come with shut-off valves that allow you to stop the flow of water without affecting the temperature. When replacing an aerator, bring the one you’re replacing to the store with you to ensure a proper fit.
