Have you ever wonder what`s inside the water we drink? Maybe we could think there are only molecules and atoms but actually there are tiny microorganisms we should be aware, like bacterium and parasites.

Nowadays pollute water produces 502.000 deaths per year. The majority of the deaths are caused by diseases like diarrhea, cholera and typhoid fever, but the strange thing is most of the cases of these of diseases occur in undeveloped countries especially where the poorest people live.

One of the causes of these problems is that poorest countries don`t have water treatment plants and most of city`s sea wages end up in lakes and rivers, bearing the contamination of drinking water.

Well then, we don`t have to worry about pollute water right? Because we live in a country where we have waste water treatment plants and most of the water we drink is filtrated ,but sadly we are completely wrong. Lawn fertilizers, rinse water from driveways and motor oil commonly end up in streams and lakes but there is another public health enemy that is affecting all of us and we don`t even notice, which is Dog`s poop.

Sorry dog lovers but the cruel reality is that dog`s poop unlike those above-mentioned sources, generates disease-causing bacteria that can make people sick. Studies done in the last few years put dogs third or fourth on the list of contributors to bacteria in contaminated waters and the name of the so-called bacteria is coliform which spread through feces. Dog also carry salmonella and giardia.

For skeptics, according to USAToday`s article in the mid-1990s, scientists perfected methods for tracking the origin of nasty bacteria in steams and seawater. The trail has led straight to the dog`s stools and even worse the research confirmed that in some beaches, dogs help raise bacteria levels so high that visitor must stay out of the water.

What can we do to solve this problem?

The possible alternative to tackle this issue depends on the city and the persons who live in your community. One alternative is that every owner carries his own bag to pick up the dog`s stool or install bag dispensers around parks and sidewalks. The another one is that some cities through banners and signs encourage dog owners to register dogs in DNA test companies and if the owner doesn’t pick up the messes he or she will be fined.
