All around the world, people need to face how they will manage the sewage water they produce.
Some countries just dump everything in a river, lake, or the nearest ocean. Others, especially more developed countries are treating the waters before they discharge on any of the natural water bodies of their countries. Even when the technology is there to treat the sewage waters, still most countries cannot pay for these kinds of systems. This creates a type of pollution that affects the ecosystem of the water bodies and the animals who live in it and from it, including the humans.
The aim of these treatments is, in general, to reduce the pollution and make it safe for the environment. To meet these ends there are several types of treatment depending on what pollutants the water is bringing and other more general factors such as location of the sewage treatment plant, climate, and ecosystems affected, etc.
Even developed countries like Canada are still facing the problems wastewaters can create in their societies. Halifax, the capital of the province of Nova Scotia with a population of 359,183 (Census 2001) located at the southeast of Canada, in touch with the Atlantic Ocean is one of the cities struggling with their sewage waters in this country.
Halifax Waterfront
One of the biggest environmental problems the city of Halifax is facing is the pollution produced by the sewage waters being dumped at the city harbour without any kind of treatment. According to Environment Canada this harbour is considered one of the biggest and deepest in the world.
The recent problem started when the new sewage treatment plant (officially open in February 2008) failed in January 2009 because of a wastewater flooding damage due to an extended local area power outage. As a result, the plant has been temporarily shut down and all wastewater previously routed through the plant is being discharged into the Halifax Harbour, dumping around 180,000,000 liters of untreated water per day. Bringing the harbour to the state it was before the construction of the sewage treatment plant.
Local universities like Dalhousie University and environmental organizations like The Ecology Action Centre are still researching how this pollution is affecting the ecosystem of the city harbour. One of the problems that scientist predict is the eutrophication of the harbour, which is the increase in concentration of chemical elements required for life. The nitrates, phosphate and organic matter found in human waste serve as a food for algae and bacteria. This causes these organisms to overpopulate to the point where they use up most of the dissolved oxygen that is naturally found in water, making it difficult for other organisms in this aquatic environment to live. The bacteria are basically strangling the other organisms. Some of the organisms that do overpopulate from this can also be disease-‐causing microorganisms. Phosphates are also found in soaps and detergents.
The Media and Other Pollutants That Has Not Been Covered
Much has been said in the national and local media about the pollution of the Halifax Harbor cause by the sewage treatment plant failure. The problem with the sewage treatment plant was also a stinky situation for the public and environmental organizations that couldn’t get information about how the plant was being managed because of the secrecy wall Halifax Regional Municipality held during the first months of the treatment plant failure.
There is another fact that is being omitted. Not only is the sewage waters contaminating the harbor but there are other chemicals that are polluting the water as well.
Yes, the sewage treatment plant failure it’s the biggest problem the Halifax harbor is confronting right now, but storm waters and chemicals people and industry throw through the pipes are also affecting the harbor.
In an interview with Richard Stephenson from the Terrain Group (one of the companies that develop sewage treatment plants) he said: “chemicals like those in the cleaning products are not treated by the sewage treatment plants, so they go directly to the oceans, creating a type of pollution that has not been covered very much. “
Restaurant owners across the harbor have said that Tourism and fishers have been affected because of the pollution of the harbor, affecting the economy of the city as well.
In an open letter to the Mayor Peter Kelly, the Canadian Restaurants and Foodservice Association s stated: “The summer months are a make-‐or-‐break time when foodservice operators rely on waterfront traffic. Yet this year, business operators report a large number of complaints from customers about the strong odours both inside and outside their businesses. In some instances the odours are so strong that customers
refuse to be seated in outdoor patio areas. Many operators believe the public awareness of raw sewage
pouring into the harbour on Lower Water Street is also keeping many local and regional customers away from the waterfront area.”
The city of Halifax plans to have the sewage treatment plant working in spring 2010. But once this happens , there are other steps people should consider in order to help maintain the waters clean. The government is not the only responsible for the harbor situation. Everyone in the city can be part of the solution for a better and less contaminated harbor.

More Clarity On The Waste Water Management On The Way
During the Atlantic Canada Water and Wastewater Association (ACWWA) annual conference celebrated last October 19 at the Marriott Hotel in Halifax, Stefan Furey from Environment Canada said the agency is working on new policies for more clarity and transparency on how the wastewater is managed. These policies will benefit both wastewaters plant owners and general public as well. “Wastewater treatment plant owners (public and private) will have to report on their plant performance and I would expect that if treatment performance does not meet their targets they would have to explain why and what they have done, or plan to do, to remedy the situation.” Said engineer Stefan Furey from Environment Canada Waste and Wastewaters branch. This statement contrast with the role Halifax Regional Municipality Stormwater/ Waste Management took during the January failure of the $54-‐million sewage plant when the facility flooded with nearly seven million liters of sewage. At that time, most of the information was held on secrecy by the city. When asked if these policies will remove the secrecy walls like those held by the Halifax municipality during the sewage system failure, Stefan said: “I can’t say if it will remove the “secrecy walls” you referred to, but there should definitely be more transparency on how a treatment facility has been operating.” The public reporting system will be developed over the next couple of years. These new policies are scheduled to take effect in 2012. On the other hand, wastewater plant owners will benefit from a new policy that unifies federal regulations and provincial regulations. “Currently there are regulations and reporting requirements that they (wastewater plant owners) have to follow from both the Provincial and Federal government. This can cause conflicts and confusion at times. We will be trying to set up policies or agreements such that the treatment plant owners will only have to deal with one regulator.” said Furey. The engineer pointed that the policies/agreements have yet to be developed and will probably take a couple more years to get in place.

The Problem Does Not Only Come From The Sewage Treatment Plant
The problem of pollution in the Harbor goes way beyond the failure of the sewage treatment plant. There are some others chemicals that are affecting it as well and there are some ways the people of the city can help to reduce the problem.
“The harbor does not only receive the contaminants from the sewage, but also from industrial actives, oil, and many house hold products” said Jocelyn Rankin from the Ecology Action Centre.
Contrary to popular belief, Halifax Regional Municipality wastewater treatment plants are not equipped to handle many toxic chemicals.
“With the sewage, the sewage treatment plant also receives a lot of other chemicals that are not treated by the plant; like those in the cleaning products. These chemicals goes directly to the water bodies without any kind of treatment” Said Richard Stephenson, engineer for the Terrain Group.
The discharge of these chemicals directly into the harbour also contributes to make the water body unusable for drinking, recreation and industry and harm aquatic life. Being aware of that, we can do several things in our home to improve the quality of water this water body.

There are many simple and economical things we can do every day to help protect the lakes and rivers of HRM, as well as the harbour. Properly dispose of products such as paints, solvents and vehicle fluids. Remember that while it is important to properly dispose of hazardous or toxic chemicals, it is good practice to use less to begin with or even better, none at all.
Elimination or reduction of pollutants at or near the source is less expensive and more effective than collecting, treating and disposal of our wastes.

Some Recipes for non-‐toxic household products that you can make at home, using ingredients you may already have:
Cleaning Products:
All Purpose:
• Baking soda and water • 1 part Baking Soda, 2
parts white vinegar, 4 parts warm water
Dish Detergent:
• Natural liquid soap, phosphate free products
Glass/Window Cleaner:
• Equal parts of white vinegar & water. Store in a clean pump spray container
Bleach:
• Borax
Drain Cleaner:
• Use plunger or mechanical snake. Flush rain weekly with boiling water.
Toilet Bowl Cleaner:
• Paste of Borax @ lemon juice. Let stand then scrub.
Scouring Powder:
• 1 cup white vinegar & 2 litres warm water
• Baking Soda (It’s non abrasive)
By employing the principles of pollution prevention, we may save money, have healthier and safer workplaces and homes, protect our natural resources and protect our environment.
At home, wastewater is not only produced when you flush the toilet, but it is also produced when you shower, wash clothes, prepare your meals, and clean up dishes, pots and pans. Not everything that is disposed of down the drain is safe for the plumbing in your house or safe for the miles of public sewers that service the community. Having that in mind, you should be aware of the chemicals you use on those activities, because they can end being part of the pollution in the waterfront.
Some of the things you can do around your home to protect the ocean are:
• Try to purchase non-‐toxic alternatives to harsh chemicals for your cleaning needs, use up the entire product and don’t purchase more than what is actually needed. Do not pour unused household chemicals down the drain or into your toilets.
• Return unused pharmaceuticals or medications to your pharmacy. Unused pharmaceuticals, medications and other personal care products should not be disposed of down your sink drains or in the toilet.
• Fats, oils and grease in the sewer system can block your sewer lateral and may result in expensive repairs to your home. Scrape grease and food scraps off your plates. Use disposable paper towels to wipe up grease and place them in your green bin. Never pour grease down the sink drains or toilets.
• Properly dispose of products such as paints, solvents and vehicle fluids. Residents may take these wastes to the Household Hazardous Waste Depot located at 50 Chain Lake Dr., Bayers Lake Business Park. Latex and oil base paints are acceptable at your local Enviro Depot (TM). Do not dispose of these wastes down the storm drain.
Rug Cleaner:
• 2 cups cornmeal, 1 cup Borax; sprinkle, leave for an hour, then vacuum.
Oven Cleaner:
• Mix paste of Baking Soda, salt, water.

Furniture/floor:
• 1 part lemon juice, 2 parts vegetable oil. Apply. Rub in. Wipe Clean.
Conclusion
In order for Halifax to preserve and to have a cleaner harbour, I doesn’t only need from all the help the Halifax Regional Municipality can bring, but also need to have the people who live nearby and enjoy this water body aware that their actions on their daily life also takes an important role on the quality of water in the harbour.
As for the problem with the city sewage treatment plant, Mayor Peter Kelly has promised several times the plant will be working back again for spring 2010. The mayor is also expecting the pollution of the water to go to lower levels as they did when the treatment plant was created in 2008. For that time, he even announced that the quality of water had improved so much that it was safe for the people to swim back again on the harbour, being himself the first to jump and swim at the Halifax bay.
Still, there will be pollution coming from the household products thrown through the pipes, the stormwaters, and the industrial actives. Additionally the harbour could be affected by residential construction projects being held nearby the harbour. Leaving a long way for environmentalists and the scientific community to research, recommend and to propose legal actions to preserve the harbour and the ecosystem it owns.
