Ensuring Safe Drinking Water at Our School

​

At our school, we prioritize the health and well-being of our students and staff. One important aspect of this commitment is ensuring that our drinking water meets safety standards. You might have heard of Total Dissolved Solids (TDS) and wondered what it means for water quality. Let us explain how we monitor and maintain safe drinking water for everyone at school.

​

Our Promise

We are committed to providing safe and healthy drinking water for all our students and staff. By understanding and managing TDS levels, we ensure that the water at our school is both safe and enjoyable.

​

Our Commitment to Safe Drinking Water

We regularly test our school's water to ensure it falls within these safe TDS ranges. Here’s what we do to maintain high water quality:

• Regular Monitoring: We conduct frequent water quality tests to check TDS levels and ensure they remain within the recommended range.

• Advanced Filtration: Our water filtration systems are designed to remove excess minerals and contaminants, keeping TDS levels safe.

• Health and Safety Compliance: We adhere to guidelines set by health authorities to ensure our water is both safe and pleasant to drink.

 

What is TDS?

Total Dissolved Solids (TDS) refer to the amount of minerals, salts, and organic matter dissolved in water. It's like how sugar and tea leaves dissolve in a cup of tea, contributing to its taste. In water, TDS is measured in milligrams per liter (mg/L) or parts per million (ppm).

​

What’s a Normal TDS Level?

There's no single "perfect" TDS number, but guidelines help us determine what's acceptable.

TDS Levels and Water Quality:

• 0-50 ppm: Very low mineral content, often associated with distilled or purified water.

• 50-150 ppm: Low mineral content, which may lack essential minerals.

• 150-250 ppm: Ideal range for drinking water, providing a balance of taste and essential minerals.

• 250-500 ppm: Acceptable range for many people but may taste slightly mineralized.

• 500-1000 ppm: High mineral content may not be ideal for long-term consumption.

• 1000+ ppm: Considered unsafe for drinking due to high levels of dissolved solids.

 

Impact of Low TDS

Water with very low TDS (below 150 ppm) might lack essential minerals like calcium, magnesium, and potassium, which are beneficial for health. This can result in water that tastes flat or bland.

​

Optimal TDS for Drinking Water:

Many health experts suggest that the optimal TDS level for drinking water is between 150-250 ppm. This range provides a good balance of essential minerals without being overly mineralized. Water in this range tends to taste better and can contribute beneficial minerals to the diet.

​

• World Health Organization (WHO): Recommends TDS levels below 300ppm (mg/L) for a pleasant taste and to avoid potential health concerns.

• US Environmental Protection Agency (EPA): Sets a maximum level of 500ppm (mg/L), focusing on taste and aesthetic qualities.

 

Why TDS Matters

While TDS levels give us an idea of the mineral content in water, it's also essential to check for specific contaminants. This is why we also test for various contaminants to guarantee overall water safety.

​

What If TDS Levels Are High or Low?

High TDS (above 500 mg/L): This might affect the taste but is generally not a health risk unless specific contaminants are present. We make sure our water TDS is between 50 to 200 TDS and adjust our filtration processes to improve taste and safety.

​

Low TDS (below 50 mg/L): Water might lack essential minerals. We ensure that our water treatment process maintains a balance of necessary minerals for good health.
