Test Information:

Total Coliform/E. coli - Mircoorganisms that are condsidered to be indicators of sewage contamination; E. coli is a species of bacteria that is part of the Coliform group of bacteria.

Nitrates and Nitrites - Chemicals that occur in water due to the breakdown of nitrogen compounds in soil and from human activities.  Fertilizers and waste runoff are possible sources of nitrates/nitrites.

Heavy Metals - Metals such as arsenic, cadmium, chromium, lead and selenium that may be found in underground rocks and soils.

Langelier Index - A means of evaluating water quality to determine if the water has potential to form a scale or cause corrosion of plumbing.

pH - A measure of the acidity or alkalinity of water; a pH of 7.0 is considered to be neutral.

Radon - A radioactive gas that is colorless, odorless, and tasteless.  Radon is naturally formed by radioactive decay of uranium in rock, soil and water.  Radon is known to be a carcinogen.

Sulfides - Chemical compounds containing sulfur, such as hydrogen sulfide.  These chemicals are known to produce foul odors.

Total Dissolved Solids - Made up of inorganic salts (e.g. calcium, magnesium, etc.) and small amounts of organic matter that are dissolved in water; considered to be an indicator of water quality.

Iron and Sulfate-Reducing Bacteria - Nuisance bactera often found in groundwater that may contribute to water discoloration and foul odors.

Arsenic Speciation - Analytical technique used to separate the different forms of arsenic (arsenic III and arsenic V).  Speciation of arsenic can be useful in determining appropriate treatment techniques, as arsenic III is significantly more difficult to remove from drinking water using conventional treatment technologies.
