There are a number of factors that may affect water clarity.  The chief factor in the clarity of lakes and rivers in Texas is sediment. The more sediment in a stream or body of water, the cloudier it appears. This factor can vary depending on geography and climate. Some areas naturally have more sediment drawn from the surrounding land, particularly agricultural areas, where soil is often broken up and exposed. Water tends to be cloudier during rainier seasons when runoff carries topsoil and oth...

Separate from sanitary water lines or wastewater sewers, storm sewers carry away surface rain runoff, street wash and snow melt via curb-side drains.  Also unlike sanitary sewers, these systems usually drain directly into a creek, river, or other body of water without treatment.  This is also how a lot of the trash ends up in our rivers and lakes.  Everything thrown out in the street or dumped in a street drain (storm drain) ends up in a nearby river or lake.Dumping hazardous substances into the...

Artesian, spring, well and ground water comes from an underground aquifer and may or may not be treated. Well and artesian water are tapped through a well.Spring water is collected as it flows to the surface, and ground water can be either.Distilled water comes from steam from boiling water that is condensed. Distilling kills microbes and removes minerals, giving water a “flat” taste.Drinking water is simply intended for human consumption and can come from a variety of sources, including publi...

Brackish is a term used to describe water that contains more dissolved minerals (see total dissolved solids) than normally acceptable for municipal, domestic and agricultural uses. It has a higher amount of dissolved solids than fresh water but not as high as saltier types such as seawater.Brackish water includes concentrations of total dissolved solids (TDS) ranging from 1,000 to 10,000 milligrams per liter (mg/l).

Turbidity is the amount of particles suspended in water. It is the factor that causes water to appear cloudy or even opaque.  It is measured by how the particles scatter light rays moving through the water.

Wetlands provide a habitat for a variety of plants and animals that would fare poorly in other environments. They also provide water storage, functioning like a sponge, storing water and slowly releasing it. This helps ease water’s potential for flooding and erosion. The slow release also contributes to surface water flow during dry periods.Wetlands also can act as a natural water filtration system. As the water enters the wetland, its movement slows around plants, which allows suspended sedime...
