WATER TREATMENT
Arsenic In Well Water

What is arsenic? Arsenic is a chemical element with the symbol "As." It is found naturally in rocks in the earth's crust. Arsenic is recognized as a poison and cancer causing substance (carcinogen). It occurs within organic compounds (combined with hydrogen and carbon), and within inorganic compounds (combined within sulphur, chlorine or oxygen).

 

In water, arsenic has no smell or taste and can only be detected through a chemical test. The ambient concentration of arsenic in surface and ground waters in Canada is very low, usually ranging from 0.001 to 0.002 milligrams per liter (mg/L). Concentrations in groundwater are often higher than those measured in surface waters. Some creeks that are recharged by groundwater with high levels of arsenic may also have high levels. The Canadian drinking water guideline for arsenic sets a Maximum Acceptable Concentration of 0.010 mg/L.

 

If your well has arsenic levels that exceed the Maximum Acceptable Concentration of 0.010 mg/L EDS can help you determine which is the best water treatment system for your home.

TIPS FOR MAINTAINING YOUR WELL
Well Logs


Owners of water wells should know that one of the most important components of their household water well system can be kept filed away-the well

log.

 

Well Head Picture

 

A well log is a document containing vital information on the construction of the well, well locations and the ground surrounding it. Contractors constructing a well must maintain a daily log containing the prescribed information and must complete a report in accordance with the regulations and submit a copy of the report in accordance with the regulations to the comptroller, well owner and if requested by the regional water manager, an engineer or a drinking water officer. Well owners should have a copy as well.

Quick access to and understanding of the well log can be crucial at such times. Well logs differ from province to province most, however, contain the same basic information , well tag information followed by areas that provide the owner and location, construction and contractor details, well testing information, and a lithology information of geologic formations encountered by the contractor. Most well logs also will have an area titled "General Remarks" where the contractor can provide additional notes.

pH Control

pH indicates intensity of a given water in terms of alkalinity or acidity.
 
There are two important things to bear in mind when considering pH:
 
1.) Always it is an intensity measure, not one of quantity.  A thermometer will tell how cold a room is but not how much warm air is necessary to heat it.
 
2.) It is an exponential function.  pH 10 is ten times as alkaline as pH 9 and one hundred times as alkaline as pH 8. Similarly, a pH 2 is one hundred times as acid as pH 4 and one thousand times as acid as pH 5.

Neutralizers are a good choice for your water system if you have water that has a low or high pH (range is 6.5-8.5). Low pH is visible as blue/green stains on fixtures, and is extremely corrosive to pipe and metal fixtures. Low pH can also interfere with the effectiveness of other water filtration, such as iron filters. By use of a media bed of corosex/calcite or soda ash, you can eliminate these problems by neutralizing your water.
