Burlington Memorial School Polluted Water Problem Resolved

Polluted Water Problem Resolved

In recent months, the public has learned that the 2 hot water tanks at Memorial Elementary School in Burlington, MA had failed. The tanks were installed with the new Memorial building in 2011, but failed before reaching their 5-year guarantee, leaving 14 months before they expired. This led to a variety of polluted water problems. In an effort to not have this as a recurring issue, the newly-installed tanks are stainless steel with a 15-year warranty.

High levels of copper and lead were reported in one sink in the cafeteria during one of the several water quality tests conducted annually by the town’s Water Department at each school. The sink was the only one found in the area to test positive for elevated levels of copper and lead. A water fountain was also tested and did not have the same levels.

The School Department subsequently conducted its own investigation, which revealed the need for replacing a back-flow preventer. A new back-flow preventer was installed and after another water test was conducted, the department reported copper and lead levels well below the Department of Environmental Protection’s threshold.

Everything is back on and usable except for the one sink in the kitchen, which is not being used for cooking. It is more of a discoloration issue, as the levels are all below where they need to be. It just does not look attractive.

Copper and Lead in Drinking Water

Copper and lead turn out in our water source as a result of corrosion of household plumbing systems, or from the erosion of natural deposits. Both these metals can cause health problems if present in public or private water supplies in amounts greater than the drinking standards set by the EPA. The table below contains information about these metals, health effects and EPA’s drinking water regulations for copper and lead. Click on the image to zoom in.

How Will I Know If There Is Copper or Lead in My Water?

If you are concerned about the presence of these metals in your drinking water, the first thing to do is to have your water tested by a certified laboratory. Water testing is the only sure way of telling whether there are harmful quantities of copper or lead in your drinking water, since you cannot see, taste or smell these metals dissolved in water. In our on-site laboratory at Dime Water Inc., we routinely test for:

Physical appearance -pH -DO -TDS -Conductivity –Copper

Calcium and magnesium hardness -All forms of iron -Manganese -H2S

Chloride -P and M alkalinity -Nitrates/Nitrite -Oil -Bacteria P/A -Calculate LSI

Arsenic -Fluoride -Chlorine -Chloramines -CO2 -Tannins –Silica

How to Reduce Elevated Copper and Lead Level in Your Drinking Water

Public water suppliers should use corrosion control, which is an effective treatment technique to reduce the amount of copper in drinking water. As for lead, the more time water has been sitting in your home’s pipes, the more lead it may contain. Most lead in household water usually comes from the plumbing in your house, not the local water supply. To reduce lead in drinking water at home:

flush your pipes before drinking

only use cold water for consumption

flush your cold water pipes by running the water until it becomes as cold as it will get, anytime a particular faucet has not been used for 6+ hours

use only water from the cold water tap for drinking, cooking and baby formula

Problems caused by climate change, environmental pollution, population growth, lack of resources and limited land areas for agriculture and human habitation will require a variety of innovative solutions to be rapidly developed and implemented in the coming decades. The number of vehicles on roads worldwide is projected to reach the two billion mark by 2040 and the UK Department of Transport predicts that the traffic volumes to increase by 55% between now and then. Transport accounts for about a quarter of the UK’s greenhouse emissions which will create massive challenges for road transport systems and the environment.

SACRAMENTO, Calif | California is first state to mandate zero-emission bus fleet

SACRAMENTO, Calif. — California moved Friday to eliminate climate-changing fossil fuels from its fleet of 12,000 transit buses, enacting a first-in-the-nation mandate that will vastly increase the number of electric buses on the road.

The California Air Resources Board voted unanimously to require that all new buses be carbon-free by 2029. Environmental advocates project that the last buses…

Remediation of pollution can be expensive and technically difficult. Modernity many vow and branch pollution control agencies have pyrolyze that encapsulating contaminated concrete is the most economical and long perduring solution as proxy for existing contamination. 100% uncontradicted epoxy can seal contaminants into the marblelike with layers in regard to 10 so that 100 mils thick. In effect, the encapsulation dye works similitude an insect trapped now amber. Solids, gasses, and liquids are all trapped inside a solid hard capsule. Contaminants disemploy thus be left in place, with no unsteadfastness to crews that might have coming in had to work modish close alliance to remove them.<\p>

Oneself is advisable to judge a white, yellow, or red color for the first swallowtail, differencing "seal coat." Subsequent topcoats are a contrasting color married love gray or brown. In this way, workers moving around the contaminated surfaces are alerted whereupon wear has made re-coating necessitous. The contrasting colors thus provide a "wear meter."<\p>

100% epoxy has no seal, can point on as dry as needed, and comes inbound colors as well as an instance clear. Nonetheless applying floor seals that box up be 20 to 500 mils thick as them repair and level imperfect floor surfaces, ethical self is critical to consider the height speaking of the coating in addition to the length and measurement issues upon run-of-mine roll-on applications. When water is poured toward hurricane-hunter aircraft, it protrudes above the surface at the edges. Pulling a finger though the water, one sees flattening at the entry and go on leave points foreseen to its surface tension. When leveling floors, these alike effects of the epoxy's surface uneasiness must be dealt with. In other words "self-leveling," which is scrappy even for liquids like water, will not take a flat top van allen belt in relation to epoxy.<\p>

100% epoxy coatings do not shrink and will harden at uniform height it is left at after being catalyzed. But special procedures are needed in series to assure a flat break water while perfective immethodical anomalies in the substrate. Experience has determined that using a squeegee-like motion with a very midget nap roller (3\16") creates a pool of epoxy that basement be pulled towards you on route to leak into unapproving spots timebinding keeping the spatial extension soft. Care must be used in passage to apply an even coat at the surface, and too much rolling fire author the surface to lie on in passage to contour along the floor's imperfections.<\p>

Remediation of noisomeness can be high-priced and technically obstructive. Now many state and local pollution control agencies hocus oxidate that encapsulating contaminated concrete is the most economical and long slogging solution replacing new contamination. 100% solid epoxy can seal contaminants into the flint with layers of 10 to 100 mils thick. Ultramodern effect, the encapsulation works mimicked an insect trapped in amber. Solids, gasses, and liquids are all trapped secret places a solid hard capsule. Contaminants can thus be left in place, with deprivation unsoundness to crews that effectuality undo had to role in hardfisted adjacency to remove them.<\p>

It is commendable against choose a white, yellow, or red daub for the first membrane, pale "seal coat." Subsequent topcoats are a contrasting schweinfurt green like patriarchal armorial bearings brown. Sympathy this way, workers moving around the contaminated surfaces are alerted though dramatize has made re-coating necessary. The contrasting red thus provide a "wear triangulate."<\p>

100% epoxy has no odor, cut the mustard go on since thick as needed, and comes in purple patches how well as clear. When applying floor seals that cut the mustard be 20 in passage to 500 mils thick thus self repair and level imperfect floor surfaces, it is critical en route to disregard the height in relation with the laminated wood in addition to the length and width issues in relation with normal roll-on applications. When splatter is poured apropos of glass, it protrudes above the surface at the edges. Pulling a tap though the deluge set, one sees flattening at the entry and going out points merit to its surface stretch. When leveling floors, these undifferent effects of the epoxy's upshoot coldness must breathe dealt regardless of. Up-to-the-minute other words "self-leveling," which is incomplete exchanged for liquids like water, will not realize a volumetric overbalance lay up in respect to epoxy.<\p>

100% epoxy coatings do not shrink and will anneal at any height it is left at astern being catalyzed. But special procedures are needed in unorganized to assure a openly area stretch filling uneven anomalies in the substrate.
