🚫 Unnecessary Additives and Contaminants in Water

Parameter	Why It’s Unnecessary or Harmful	Ideal Target
Fluoride (F⁻)	Added for dental health, but prolonged fluoride exposure has been linked to lower IQ in areas with high fluoridation, as suggested by multiple studies (e.g., 2019 U.S. and Canadian research). Excessive fluoride may also contribute to thyroid dysfunction and bone weakening.	0 mg/L
Chloride (Cl⁻)	Often present due to chlorine disinfection or natural sources. High levels can cause a salty taste and corrosion in plumbing.	< 50 mg/L
Copper (Cu)	Comes from corroding pipes rather than natural water sources. High levels cause a metallic taste and potential health effects.	< 0.5 mg/L
Manganese (Mn)	Naturally occurring but contributes to staining, metallic taste, and potential neurological effects at high levels.	< 0.05 mg/L
Iron (Fe)	Can come from plumbing or groundwater. Causes staining, bad taste, and appliance buildup.	< 0.1 mg/L
Nitrate (NO₃⁻)	Usually from agricultural runoff. Long-term exposure is linked to potential health risks, including "blue baby syndrome" in infants.	< 1 mg/L
Sulphate (SO₄²⁻)	Naturally occurring but excessive amounts can have a laxative effect and cause water to taste bitter.	< 50 mg/L
Total Dissolved Solids (TDS)	Measures the overall mineral content. Too high can cause taste issues and appliance scaling.	50 - 150 mg/L
Turbidity (Cloudiness)	Should be as close to 0 as possible for clean, pure water.	< 0.5 NTU
Silica (SiO₂)	Naturally occurring, but excessive levels can lead to scale buildup on appliances.	< 10 mg/L

✔️ Naturally Present & Beneficial Elements in Water

Parameter	Why It’s Okay	Ideal Range
pH	Best when neutral for taste and plumbing safety.	7.0 - 7.5
Alkalinity	Helps stabilize pH and prevent pipe corrosion.	60 - 80 mg/L
Hardness (Calcium & Magnesium)	Essential minerals for health, but excessive hardness causes scaling.	60 - 120 mg/L
Sodium (Na)	Naturally occurring but should be kept low for health and taste.	< 50 mg/L

🌊 Summary: How to Improve Your Water Quality

🔹 Remove fluoride completely to avoid potential cognitive effects and thyroid risks.
🔹 Reduce chlorine and chloride for better taste and less corrosion.
🔹 Minimize heavy metals like copper, iron, and manganese for purity.
🔹 Lower TDS slightly to improve taste and appliance longevity.

✔️ Recommended & ❌ Unnecessary Parameters in Rainwater

Parameter	Recorded Reading	Safe Range	Ideal Range	Recommended?
pH	6.34	5.5 - 8.5	6.5 - 7.5 (Neutral for best taste & safety)	❌ (Slightly acidic)
Turbidity (Cloudiness)	0.02 NTU	0 - 5 NTU	< 0.5 NTU (Clear water)	✅
Total Dissolved Solids (TDS)	11.63 mg/L	0 - 600 mg/L	10 - 50 mg/L (Balanced minerals, no scaling)	✅
Total Hardness	8 mg/L	0 - 200 mg/L	< 50 mg/L (Soft water, prevents scaling)	✅
Iron (Fe)	0.03 mg/L	0 - 0.3 mg/L	< 0.1 mg/L (No staining or metallic taste)	✅
Manganese (Mn)	0.009 mg/L	0 - 0.5 mg/L	< 0.05 mg/L (Prevents staining & neurological effects)	✅
Sodium (Na)	1 mg/L	0 - 180 mg/L	< 10 mg/L (Avoids salty taste)	✅
Chloride (Cl⁻)	1 mg/L	0 - 250 mg/L	< 10 mg/L (Prevents corrosion)	✅
Sulphate (SO₄²⁻)	0 mg/L	0 - 250 mg/L	< 10 mg/L (Avoids taste & digestive issues)	✅
Alkalinity	13 mg/L	Moderate	20 - 50 mg/L (Balanced pH stability)	❌ (A bit low)
Nitrate (NO₃⁻)	0.72 mg/L	0 - 11.3 mg/L	< 1 mg/L (Prevents health risks)	✅
Copper (Cu)	2.24 mg/L	0 - 2 mg/L (Exceeds limit)	< 0.5 mg/L (Prevents metallic taste & toxicity)	❌ (Too high, likely from pipes)
Silica (SiO₂)	0.1 mg/L	0 - 80 mg/L	< 10 mg/L (Avoids deposits on fixtures)	✅
Fluoride (F⁻)	0.59 mg/L	0 - 1.5 mg/L	0 mg/L (Not needed; linked to lower IQ & thyroid issues)	❌ (Should be removed)
Conductivity	18.17 uS/cm	Optimal	10 - 100 uS/cm (Indicates low impurities)	✅

🚫 Unnecessary Contaminants in Rainwater

Contaminant	Why It’s Unnecessary or Harmful?	Ideal Level
Fluoride (F⁻)	Not naturally present in rainwater. Studies (Harvard, U.S. EPA) link prolonged fluoride exposure to lower IQ, thyroid dysfunction, and skeletal issues.	0 mg/L
Copper (Cu)	Exceeds safe limit. Likely from corroding pipes or roofing. High levels can cause metallic taste and health risks.	< 0.5 mg/L
pH (Acidic Water)	Slightly too low. Acidic water can cause pipe corrosion and leach metals like copper into the water.	6.5 - 7.5
Alkalinity	Low alkalinity can make water unstable and prone to pH fluctuations.	20 - 50 mg/L

Home and Plumbing Impacts

🔹 Total Hardness (8 mg/L in rainwater): Extremely soft water, which can be corrosive to pipes, leading to potential metal leaching from plumbing.

🔹 Iron & Manganese (Rainwater: Iron 0.03 mg/L, Manganese 0.009 mg/L): Low but can cause sediment buildup over time if not filtered.

🔹 Copper (2.24 mg/L in rainwater): High levels may indicate corrosion in metal roofing or pipes, leading to health and plumbing concerns.

Should You Use a Water Filtration System?

For both mains and rainwater users, filtration is essential to ensure clean, safe drinking water. Here’s what we recommend:

✅ For Rainwater Users:

Puretec Hybrid G Series: Great for sediment, bacteria, and chlorine removal (if rainwater is treated).
Puretec Reverse Osmosis (RO) System: Removes copper, fluoride, and dissolved contaminants.
Puretec Filter Wall System: A high-flow system for whole-house filtration.

✅ For Mains Water Users:

Puretec X3 or Z1 Series: Best for drinking water filtration.
Puretec Reverse Osmosis (RO) System: Removes fluoride and heavy metals.
Puretec Filter Wall System: A high-flow system for whole-house filtration.
