When on vacation it's not uncommon for travelers to consume alcoholic beverages and this can become a problem as warm weather and heat can increase the effects of alcohol, contributing to dehydration and increased fatigue during high-intensity exercise. Some physical effects of ingesting alcohol are weakening of the pumping force of the heart, decreased coordination, slowed reaction time, muscle relaxation, lack of behavioral inhibitions and impaired judgment which when lounging on a beach, might prove perfectly acceptable. However should the intrepid inebriated individual decide to participate in physical activities such as swimming after tossing down a few umbrella decorated drinks the risk of injury or death can be dramatically increased.
Rip Currents:
A rip current is a strong flow of water returning seaward from the shore. It is often called a riptide, rip current, a rip, or an undertow. Rip currents can be dangerous for both swimmers and waders by dragging one away from the beach and causing exhaustion when the swimmer fights the current. They occur most often when the tide is low and there are strong onshore winds with rough surf. Increased wind blowing shoreward combined with the pressure of incoming water pressure push more water toward the shore and create a situation wherein the returning water has to find an alternate means to flow back into the sea. Typically, this water will flow parallel to the shore until it finds an easier route away from the shore either through lessened incoming water pressure or a physical feature on the beach that lends itself to facilitating outflow such as a pier, jetty or a split in a barrier sandbar or reef. This strong outflow is usually not terribly wide but is powerful at the surface and will prevent incoming swells and waves from being too pronounced, actually creating a deceptively inviting area of calm water for swimmers.
Obviously, it is advisable to look for the existence of a rip current before heading into the water. Some indicators to look for on the beach prior to entering the water are wave actions inconsistent with the surrounding area such as unusually calm waters, discoloration caused by the strong outgoing current carrying excess debris and soil and waves that don't wash as far up on the shore as the surrounding area. If you are caught in a riptide, DO NOT PANIC. Understanding that they are generally narrow in width and are simply an outgoing current, float do not struggle. Let the riptide carry you out beyond the breakers and it will dissipate. If you prefer, swim parallel to the beach not directly toward shore. In this way you will cross the current and are less likely to exhaust yourself.
Interestingly, rip currents are used by surfers and lifeguards as they ride the outgoing current to carry them away from shore faster than they would normally be able go to by paddling through the waves.

The requirements for water quality have been increasing steadily, a thing which has caused the water treatment industry to begin making existing techniques better and to combine different methods as to be able to explore the new technologies that will make the water cleaner.
The improvements that have been made in recent years are considerable, but unfortunately this doesn't stop different myths and misconceptions from existing. Moreover, dedicated scientists have found that there really are no two water treatment problems exactly the same.
Minor differences will always exist with more than one technically-acceptable and scientifically-sound solution to any given water treatment problem. The first reasonable conclusion is that there are no absolutes when it comes to water treatment issues.
Water in its pure form is considered to be one of the most aggressive solvents known and it bears the name of "universal solvent." Water, to a certain degree of course, will dissolve virtually everything to which it is exposed or which gets exposed to it. Pure water has a high energy value. Moreover, basically like everything else in nature, it strives to achieve energy equilibrium with the surroundings.
To do that, it will attempt to dissolve the quantity of material until the solution reaches the state called saturation, which actually is the point at which there are practically no more solids that can be dissolved in the surrounding environment. The most important contaminants found in water are atmospheric gases, minerals and organic materials.
A major problem concerning water purity is bacterial contamination and control of bacterial growth. Water is essential to life, at least the way we know it. It is a necessary medium for bacterial growth because it carries the nutrients which are so important for the development of life. The water also has a thermal stability which provides a controlled environment.
Nowadays, there are four visible trends which are occurring in the world. The first one is the deterioration of the water supplies from increased chemical abuse. The second one is the development of more advanced instruments capable of detecting water contaminants.
The third trend is the growing acknowledgment of the general public towards water quality and the regulating authorities' response in mandating high standards.
Finally, the fourth important trend refers to the development of new or refined high-technology products and biotechnology products which require ultra pure water as part of their manufacture. Water treatment techniques will require even greater sophistication in years ahead, if we want to drink pure water in the future also.
