Hard water is the most common problem found in the average home. Hard water happens when calcium, magnesium, lime or other hardness minerals are dissolved in the water supply. This can cause soap to be less effective, such as dishwashers, laundry and showers. Water softeners remove these minerals through an automated process and without adding any sort of chemicals to your water supply.
The Hydrologic Cycle (also called the Water Cycle) is the continuous movement of water in the air, on the surface of and below the Earth. This cycle is the exchange of energy which influences climate. When water condenses, it releases energy and warms the environment. When water evaporates it takes energy from the surrounding environment, dropping temperatures.
The Great Pacific garbage patch is a whirlpool of marine debris, mostly tiny pieces of plastic, in the central North Pacific Ocean. The patch mostly consists of pelagic plastics, formed from plastic bags, plastic water bottles, bottle caps and styrofoam. Plastic does not biodegrade, the sun breaks these down into smaller and smaller pieces through photodegradation, which is why it is so difficult to judge the size of the patches, since these pieces are not visible from satellites or planes.
Water filter cartridges come in varying micron sizes, surfaces and layers. Choosing between these options is dependent on the type of sediment or contaminants that need to filter from the water.
Nutrient pollution affects air and water around the country. Pollutants often enter upstream waters like creeks and streams and then flow into larger water bodies like lakes, rivers and bays. Excess nitrogen and phosphorus can also travel thousands of miles to coastal areas where the effects of the pollution are felt in the form of massive dead zones, such as those in the Gulf of Mexico and Chesapeake Bay. More than 100,000 miles of rivers and streams, close to 2.5 million acres of lakes, reservoirs and ponds, and more than 800 square miles of bays and estuaries in the United States have poor water quality because of nitrogen and phosphorus pollution.

Hydraulic fracturing (sometimes referred to as fracking or hydrofracking) is a relatively new form of natural gas extraction where a well is drilled and then highly pressurized fluid is injected into the well which then opens fractures in the rock formations deep below, releasing natural gas from reservoirs which would have otherwise remained trapped or released slowly through natural hydraulic fracturing or more traditional forms of gas drilling.

Hexavalent chromium (or Chromium 6) is a group of chemical compounds containing the element chromium that is odorless and tasteless. It is used in the production of stainless steel, textile dyes, wood preservation, leather tanning, and a variety of other applications. Hexavalent chromium is a probable carcinogen and was brought to national attention when it was found in the drinking water supply of the southern California town of Hinkley, and the subsequent involvement of Erin Brockovich.
