Different levels of ammonia. Save vs. Unsafe

Granulated activated carbon filtration (GAC) effectively removes organic contaminants from water, but this filter system collects nitrate during the treatment process and then releases it into the water. Since nitrification occurs frequently with ammoniated waters, monitoring the amount of ammonia in GAC filters can control nitrate levels. This system reduces total ammonia in the system.

Gives an explanation of the importance in purifying water to ensure that there is no more ammonia in it. This website also gives diagrams and pictures of an ammonia purification system.

Sparkling crystal clear water is possible with the use of a whole house turbidity & sediment filter. Learn about the causes, problems and solutions of sediment in well and tap water. Compare the different filtration and water purification methods for treating turbidity including micron cartridge filters, pleated filters, string wound filters, and zeolite media filters.

This website gives ideas for filters that reduce or get rid of turbidity.

This website explains how to make a water purification system and how it works.

This is how you can measure the light through water.

Clinoptilolite is not the most well known, but is one of the more useful natural Clinoptilolite is used in many applications such as a chemical sieve, a gas absorber, a feed additive, a food additive, an odor control agent and as a water filter for municipal and residential drinking water and aquariums. Clinoptilolite is well suited for these applications due to its large amount of pore space, high resistance to extreme temperatures and chemically neutral basic structure.

Explains turbidity, how to treat it, and most importantly provides a cheap way to build a turbidity tube with household materials.

This tells you how to measure ammonia.

Explains the use of the secchi disk, a common tactic in determining turbidity of water.

Scientific information about ammonia, how to measure ammonia, why it's important, basic overview of ammonia, what affects it in water, and the acceptable ranges

tells how to find the ammonia level in water using temperature and PH level. ( table: http://www.thefishsite.com/articles/contents/ammon3.jpg )

Tells of ways to reduce turbidity using solar disinfection with UV plus heat in clear bottles for sunlight penetration, and UV irradiation with lamps, effective treatment of turbid water remains a challenge.

This source explains some ways to prevent turbidity as well as multi-layer ways to remove turbidity.

This source explains what turbidity is and what causes it.

Another listing of different purification methods. Includes others not noted in the HoWF website and contains simple, useful visual aids.

2008 WHO Report on the international water crisis. Provides a look at various diseases and contaminants of concern, as well as solutions and other facts in relation.

A catch-all, scholarly view of the international drinking water issue. Outlines clearly the various pathogens/diseases that give cause to the water purification mission, as well as chemical contaminants, global impact and possible solutions. Lengthy, but relevant read

The site provides an in-depth look at different methods of water purification, including distillation, reverse osmosis, and filtration. While the information is geared towards promoting the filtration option, it's almost 100% objective and provides a lot of detail.

Good descriptions and tables of various kinds of water filters, with charts to provide visual aid.
