By "blurd" do you mean milky?

What is the nature of your water? (hard / soft, pH)

partial in cloudy term, with a ligght green color.

and why is that our effluent is bubbly but it passes all the test.

The thing is, with blurd, you never have to ask.

Blurd stands out from other colors in the extent to which it is found.

The frequency with which blurd is observed is of sufficiently profound difference to the frequencies with which all other colors are found, that quantum observation laws to dominanate.

This curiously allows determination of the validity of a report of observatioon of blurd, without further investigation.... sight unseen, as it were.

My vision is now blurd with tears of laughter. Maybe I am lucky other people see dots or stars.

You sure it isn't your pool water that you may have over shocked it.

Hello irein09,

Do you get your water from a well? By 'blurd' did you mean turbid? Muddy, and cloudy, sometimes smelly?...........What a picture you paint! Way ahead of anything else in in the nasty look and smell list is Chlorine. Here is a piece I found that may explain:

Turbidity, Color, Odor, and Taste in Domestic Water

Ronald E. Hermanson, P.E.

From the clouds to the tap, water contacts and carries many substances, including gases, minerals, and organic matter. Many of these are impurities that interfere with water use by humans. Some of these impurities are completely dissolved; others are solid, suspended particles in the water that cause objectionable cloudiness, color, odor, and taste.
Finely divided, solid particles that absorb or reflect light cause "cloudy water," or turbidity. These particles are generally unresolvable, inorganic mineral matter or organic matter picked up by water flow over and through the ground. Surface water from lakes, streams, and ponds usually has significant amounts of turbidity from surface water runoff, or from bottom deposits stirred up by water movement. Because the earth normally serves as an excellent filter, it is unusual to find significant amounts of turbidity in water from deep wells.
Water drinkers find turbidity objectionable primarily because the physical appearance of "dirty water" is less appealing than clear, sparkling water. Turbidity caused by inorganic minerals is undesirable because its abrasiveness can erode a plumbing system's pipes and fittings, and score its valve seats and washers. Turbidity caused by suspended organic matter is objectionable because it can stain sinks and fixtures, and discolor laundered fabrics.
Dissolved organic matter causes most water color. Surface water usually has some color, and it is sometimes found in well water. This often occurs in areas where swamps or bogs are common. The water picks up colored substances extracted from decaying organic matter. Dissolved organic matter also makes water unpleasant to drink, frequently contributes tastes and odors, and stains surfaces and materials. Even low amounts of organic matter may produce unpleasant "off" tastes and musty odors in drinking water, and foods and beverages prepared with the water.
Hydrogen sulfide gas in water, or sulfur water, produces a rotten egg odor, corrodes plumbing metals, and rapidly tarnishes silver. Even very low concentrations of hydrogen sulfide produce a strong, easily identifiable odor. Minerals dissolved in water at moderate levels add a taste pleasant to most palates; "flat" water appeals to few people. However, too high a mineral concentration gives the water an unpleasant soda or salty taste.
The U.S. Environmental Protection Agency and the Washington Administrative Code for Public Water Supplies has set limits for physical characteristics of water.
Drinking water should contain no impurity that would offend the senses of sight, taste, or smell. Under general use, do not exceed the following limits:

These characteristics are measured by laboratory tests. Although these tests do not directly measure the safety of the water, they are related to consumer acceptance. One unit of turbidity, 15 units of color, and a threshold odor number of 3 are levels at which these characteristics become objectionable to a considerable number of people.

It sounds like your treating surface water for potable purposes. Be careful! Chlorinating naturally occurring precursers in water can result in some nasty by-products such as THMs.... these are carcinogenic. Suggest you get in contact with an expert such as Degrémont Technologies.

we treat the water prior to discharging to the city sewage as effluent.

Hi Irein. It's normal. I was a plant operator for 30 years. Why is water (blue)? The question is as common as why is the sky blue. Water has an intrinsic color, the less turbidity, the lower the dissoved constituents, the greater the depth of water must be to see it. Snow and ice exibit the same colors. Brilliant blue to blue green.

There are far too many factors to really explain it here, but relax, it's normal.

It depends. It could be normal and no problem, it could indicate that there the filtering and other purification apparatus is not functioning properly, or it could indicate that you have allowed the chlorine content to fall below the required level for long enough that a chlorine-resistant community has been able to develop. Or it could be something as simple as bubbles being forced into the water. It is impossible to comment sensibly without knowing both the application and the chemical limits on the incoming water after you have performed the pre-chlorination treatments. (If it's part of a recirculating system, it could also indicate corrosion).

If you aren't certain, send some of the water for analysis and/or talk to the local plant inspectorate.

we do have a monthly water testing and somehow all of it indicates that our water passes and able to discharge to the city sewage.

but why is it that there are times that our effluent rpoduce bubbles? is it just because of the force of the water that flows down?

Without more details it may be a little difficult to answer this question. Vigorous agitation can cause fine bubbles that can cause blurring, or it may also be due to fine suspended solids, while a green color can be due to anything from algae to the presence of dissolved copper salts.
