Well,

environmental indicators(DO, BOD, NO3, PO4......etc)

Physicochemical Indicators IONS and Trace elements.............

Regards

At the top of my mind, at least for potable water (cosmetic/aesthetic):

Salinity, dissolved nitrates/nitrites/ammonia, Amount of Chlorine, physiologically compatible pH, absence of pathogenic microbes, appearance (color), odor, should contain minerals, absence of sulfides, free radionucleids, metal contaminants (as much as practicable), POPs, permissible TDS etc.

For drinking water; pH, TDS, TSS, Chloride, calcium, magnesium, potassium, sodium, carbonates, bicarbonate, flouride.

thanks lot my friends

World Health Organisation Guidelines for drinking-water quality

TDS, pH, BOD and turbidity will be the most essential info required to decide drinking water suitability.

Dear Mr. Thamer Almayah

Check the answer added by Mr. Joan Nyika. Every country should have your own regulation standards. Please, look for it on the normalization office of your country.

Thanks lots Mr.

Major Water Quality Parameters are Total Dissolved Solids (TDS), Electrical conductivity (EC) and Pondus Hydroxonium (PH)

its necessary to analyse les nitrogen element such as Nitrates (NO3-), Nitrites (NO2-) and Ammonium (NH4+) and the bacteriological parameters

Check Indicator micro organisms of recent feacal pollution, toxic heavy metals and POP

Dear Researchers on WQPs,

To explain in simple language,

We used to use catch word and explain to Communities.

It should be simple for All to understand the importance of quality of water - WQPs, with respect to its parameters.

We use a word - C A T S,

having 4 letters indicating

4 important factors.

C stands for Clean and Clear,

A is to say Alkaline ie pH 7.5

T indicates Taste ie on dissolved matter minerals, salts Etc. and

S is for Sterile to say bacteriologically good .. E coli pathogens and others.

Now these are maintained by monitoring the elements, that are desired and not desired.

3 forms of Science are applied :

P physical purity

C chemically good

B Biological.. as water is more important.. it is termed as

Micro biological purity.

The above details can be expanded dependent on the sourced water, source and others.

Apt practices are evolved and made use of to make water fit for potable purposes.

Well wishes ,

Dear Mr. Thamer Almayah

Please, read the attached interesting paper.

Turbidity, Odour, taste, BOD, COD, TDS, DI, TDO and heavy metal compostion.

Lastly, microbial count

Consider both biophysical and chemical parameters. They are quite important in evaluating water quality.

Dear researcher,

It is necessary to assess various physical, chemical and (micro)biological parameters for confirming its quality for drinking water.

Examples of physical parameters are: Turbidity, pH, Color, Taste and Odor, Electrical Conductivity (EC) and Total Dissolved Solids (TDS).

Similarly, Iron, Manganese, Arsenic, Nitrate, Ammonia, Total Hardness, Calcium, Iron, Residual Chlorine are key chemical parameters.

On the other hand, Eshcherichia coli (E.coli) and Total Coliform are important microbiological parameters.

The concentration limits of such parameters can be considered from Guidelines for Drinking Water Quality by WHO (https://www.who.int/water_sanitation_health/publications/drinking-water-quality-guidelines-4-including-1st-addendum/en/).

Also, separate drinking water quality standard can be referred country wise.

Thanks lots my dear Kishor Kumar Shrestha

Thanks lots dear Kibet Ronald

If you need to create a Water Quality Index (WQI) you have decide parameters with respect to physical, chemical and biological parameters. physical and biological parameters are very confined and clear. when you deciding chemical parameters you have to give priority for critical units which are very crucial for that area

Turbidity, salinity, Ph level and contamination of organic and inorganic compounds

Hello

Start with pH, TDC,salinity, conductivity, turbidity, determination of ions and cations

and determination of heavy metal

The assessment of groundwater for drinking purposes generally focus on physical , chemical and biological parameters.

Physical parameters include: pH, Temperature, conductivity, color, turbidity, odour

others include: Total dissolved solids, total suspended solids

Chemical parameters include: Major ions (Ca2+, Mg2+, Na+, K+, HCO3-, Cl-, SO42-), Nutrients ( NO3 or NO3-N, NO2- or NO2-N, NH4-N, PO4-P) total hardness, Calcium hardness (as CaCO3), Magnesium hardness ( as CaCO3), Total alkalinity (as CaCO3), Carbonate and flouride. Naturally occurring heavy metals such as iron (total), Manganese. Depending on the geology of your area the list of naturally occurring heavy metals could increase.

Biological parameters include: ecoli, feacal coliform, etc.

In the case of surface water, the anthropogenic activities going on around the water body could be taken into consideration and environmental parameters could be added to the above list.

Adding further to@ Dr.Collins Tay's

answer would want to know more specific details on the origin of sourced water ie from ground water at what levels b g l, surface water ponds, lakes others any other source.

Next would be for what purpose is the water intended for ie uses and others. If usage is for potable purposes the parameters/ qualty to comply with, would be more stringent and intricate.

There is also a neo- source from recycled water ex. outlet of wwt plants.

In order to optimise usage of water and not wasting the previous resource , we resort to usage of once used water recycled water for secondary purposes viz. as service water, irrigation of farms gardens Etc.

These points on WQPs are taken into consideration on resource of input supply and usages of said water.

Well wishes.

Dear Dr. Prof Dr Suhad Qasim saeed Almousawi Thanks a lot for your comment and contribution, really thanks.

In Australia, we undertake a risk assessment process as described by the Australian Drinking Water Guidelines - Risk management framework (NHMRC). This allows you to identify the critical measures you need to monitor for your specific water quality, catchment characteristics, treatment methods and distribution system issues. As well your regulator should provide guidance. I'm not sure about your situation but you may need to include the level of risk you are willing to accept.

You need to try and find out the amount of emerging pollutants like hormones, perfume content if the water is to be used for drinking purposes.

Dear W T A and Researchers.

In community when we give awareness on drinking water quality,

we talk about 4 factors ie

C - means clean and clear,

A- Alkaline pH @7.5

T- Taste with apt salts TDS

S- Sterile no E coli, virus Etc.

Then we look for 3 Sciences to indicate pollution

P physical

C chemical

B Micro biological

All the best..

Prof Ajit Seshadri.

Parameters of water quality for drinking water which should be assessed are mainly turbidity, electrical conductivity, pH, Dissolved Oxygen, total dissolved solids, total suspended solids and heavy metals such as iron, lead, copper, magnesium, zinc, arsenic, mercury etc.

Munira Nasiruddin Ajit Seshadri Kiprotich Kiptum Thank you for comment and contribution. Really thanks for your support and kindness

There are three types of water quality parameters physical, chemical, and biological. You may visit the link below:

Dear researchers

You can read a interesting book "Water Quality Indices" (Authors: Tasneem Abbasi S Abbasi). This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials.
