Tap Water Scoring Methodology

Scoring Framework

Base Scoring

• Starting point: 100 points
• Penalty per contaminant: 5 points base
• Amount consideration: Additional penalty based on levels above guidelines
• Maximum penalty per contaminant: 45 points

Normalization Process

Our tap water scoring uses a specialized normalization process to ensure meaningful scores:

• Score range: Ensures all scores fall between 1-100
• Ratio-based calculation: Accounts for varying contamination levels
• Rounded results: Final scores are whole numbers for clarity

Penalty Calculation Method

To maintain balance and comparability across different water systems:

• Severity weighting: Each contaminant’s “over guideline” penalty is scaled by its health severity (1–10), so higher-severity contaminants (e.g. PFAS, lead) reduce the score more than lower-severity ones.
• Total penalty: Base penalty per contaminant (3 pts) plus a weighted total of guideline exceedances (×0.5) for a healthier distribution and higher average while preserving accurate relative order.
• Bottom range: Very low raw scores are remapped into 1–40 using a log scale (not linear) so that bad systems spread evenly across the band instead of clustering at a single value (e.g. 8 or 20). Worse water still scores lower; the spread is more even.
• Bell curve: A light pull (8%) toward the middle (50) keeps the distribution even without distorting accuracy.

Evaluation Criteria

Contaminant Assessment

Each contaminant found in tap water is evaluated based on:

1. Presence detection: Whether the contaminant is detected
2. Guideline comparison: How levels compare to EPA and health guidelines
3. Health impact severity: The potential health effects of the contaminant
4. Concentration levels: The actual measured amounts

Common Contaminants Evaluated

• Chlorine and chloramine: Disinfection byproducts
• Heavy metals: Lead, mercury, arsenic, chromium
• PFAS chemicals: Forever chemicals and their variants
• Nitrates and nitrites: Agricultural runoff contaminants
• Microbiological: Bacteria and other pathogens
• Radiological: Radium, uranium, and other radioactive elements

Data Sources

Tap water scores are based on:

• EPA compliance monitoring data
• Consumer Confidence Reports (CCRs)
• Independent third-party testing
• Environmental Working Group databases
• State and local health department reports

Scoring Interpretation

Score Ranges

• 80-100: Excellent water quality with minimal contaminants
• 60-79: Good quality with some minor concerns
• 40-59: Fair quality, filtration recommended
• 20-39: Poor quality, filtration strongly recommended
• 1-19: Very poor quality, immediate action needed

Limitations

• Scores reflect available testing data only
• Some contaminants may not be regularly tested
• Seasonal variations may not be captured

Fragrances & Perfumes Scoring Methodology

Our fragrance scoring system evaluates candles, perfumes, room sprays, diffusers, wax melts, and incense based on ingredient safety, transparency, emissions, and use patterns.

Scoring Formula

Final Score = 100 – (Ingredient Penalties + Transparency + Emissions + Use Pattern)

Scoring Components

A. Ingredient Penalties (0–75 points)

Ingredients are assessed based on their severity and exposure risk:

Severity Classifications

• High severity (7 pts): Phthalates, synthetic musks, thick soot producers
• Medium severity (4 pts): Limonene, linalool, BHT (butylated hydroxytoluene)
• Low severity (2 pts): Minor sensitizers, low-risk synthetics

Exposure Multipliers

The base penalty is multiplied based on how the product is used:

• Burn (candles): ×3.5 multiplier (highest exposure risk)
• Spray (room sprays): ×2.5 multiplier (inhalation risk)
• Leave-on (perfumes): ×2 multiplier (prolonged contact)
• Diffuse (diffusers): ×1 multiplier (lowest exposure)

Multi-Ingredient Penalty

Products with many harmful ingredients receive additional penalties:

• 5-9 harmful ingredients: +10% additional penalty
• 10+ harmful ingredients: +15% additional penalty

Example: A spray with limonene (medium severity, 4 pts) would receive: 4 × 2.5 = 10 points penalty. Example: A spray with 8 harmful ingredients totaling 50 points would receive: 50 + (50 × 0.10) = 55 points penalty.

B. Transparency Penalty (0–15 points)

Ingredient disclosure transparency affects scoring:

• Full ingredient list: 0 points (best practice)
• IFRA allergens only: -3 points (partial disclosure)

Milk Scoring Methodology

Everything is scored out of 100, and we penalize each item depending on several key factors related to animal welfare, feed quality, processing, and contaminant exposure.

Evaluation Factors

Our milk scoring system evaluates products based on the following criteria:

• Living conditions - How cows are raised (pasture-raised to confined)
• Feed quality - Type and quality of feed given to cows
• Hormone use - Use of growth hormones (rBST/rBGH)
• Antibiotic use - Presence and frequency of antibiotic treatment
• Processing level - Raw, pasteurized, or ultra-processed
• Pesticide exposure - Risk of pesticide residues
• Additives - Synthetic vitamins, stabilizers, or thickeners
• Organic certification - USDA organic or equivalent certification
• Packaging - Material safety and leaching considerations

Scoring Components

Living Conditions

Penalty Range: 0-30 points

The living conditions of dairy cows significantly impact milk quality and nutritional content:

• Pasture-raised: 0 points (best - continuous outdoor access with low density)
• Free-range: 8 points (good - daily outdoor access)
• Cage-free: 16 points (moderate - indoor barn, no confinement)
• Caged/Confined: 30 points (worst - conventional confinement operations)
• Unknown: 15 points (default penalty if not specified)

Note: Pasture-raised dairy cows produce milk with higher omega-3 content, more CLA (conjugated linoleic acid), and better overall nutrient profiles compared to confined cows.

Feed Quality

Penalty Range: 0-25 points

The type of feed directly affects the nutritional value and potential contaminant load of milk:

• Pasture forage / Grass-fed: 0 points (best - 100% grass/pasture diet, zero grain supplementation)
• Corn/soy free: 8 points (good - uses grain but verified NO corn or soy)
• Majority pasture: 15 points (moderate - >50% grass but some corn/soy supplementation)
• Conventional corn/soy: 25 points (worst - primarily grain-fed or >20% corn/soy)
• Unknown: 18 points (default penalty if not specified)

Important: Most "grass-fed" brands still supplement with conventional grain. True 100% grass-fed/pasture-forage milk is rare and commands premium prices.

Hormone Use

Penalty Range: 0-10 points

Synthetic hormone use in dairy production affects milk quality and has potential health implications:

• rBST-free / No added hormones: 0 points (best - no synthetic growth hormones)
• Conventional: 10 points (worst - uses rBST/rBGH growth hormones)
• Unknown: 5 points (default penalty if not specified)

Note: rBST (recombinant bovine somatotropin) increases milk production but is linked to higher IGF-1 levels in milk. Many countries have banned its use.

Antibiotic Use

Penalty Range: 0-12 points

Antibiotic use in dairy farming affects both milk safety and contributes to antibiotic resistance:

• Never: 0 points (best - no antibiotics ever used)
• Therapeutic only: 4 points (acceptable - antibiotics only when cows are sick)
• Routine use: 12 points (worst - preventive/routine antibiotic use)
• Unknown: 6 points (default penalty if not specified)

Processing Level

Penalty Range: 0-12 points

The level of processing affects nutrient preservation and enzyme activity:

• Raw: 0 points only when raw_milk_microbial_evidence on the product is producer batch testing or third-party verified. If raw milk is flagged but we have no documented microbial screening, we apply the same penalty as pasteurized milk (5 points) until better sourcing exists. That default is intentional: unpasteurized milk is high-variance for safety, and we do not treat “unknown” as “low risk.” Additionally, if the product is not Oasis lab-tested (is_indexed) and microbial evidence is still unverified, we apply a separate raw milk uncertainty deduction so the overall score reflects safety we cannot verify from metadata alone.
• Minimal: 2 points (light pasteurization, vat pasteurized)
• Pasteurized: 5 points (standard pasteurization - 72°C for 15 seconds)
• Ultra-pasteurized: 10 points (high heat - 138°C for 2 seconds, extended shelf life)
• Ultra-filtered: 12 points (heavy processing - removes lactose and some nutrients)
• Unknown: 5 points (default penalty if not specified)

Note: Heat treatment reduces the chance of illness from germs that can be present in milk. Raw milk may retain more native enzymes and heat-sensitive nutrients, but pathogens such as Listeria, E. coli, and Salmonella remain a real concern when milk is not pasteurized or when handling and testing are inadequate. Public health agencies generally advise infants, young children, people who are pregnant, adults aged 65 and older, and people with weakened immune systems to avoid raw milk. What is legal and how it is sold varies by jurisdiction; our score reflects product attributes we can model, not whether raw milk is lawful where you live.

Pesticide Risk

Penalty Range: 0-12 points

Pesticide exposure comes primarily through contaminated feed:

• Low: 0 points (organic or verified low-pesticide feed)
• Medium: 6 points (standard grain feed)
• High: 12 points (conventional commodity feed with known pesticide residues)
• Unknown: 6 points (default penalty if not specified)

Additives

Penalty Range: 0-10 points

Some milk products contain additives for fortification or stability:

• None: 0 points (best - no additives)
• Natural only: 2 points (natural vitamins like vitamin D3)
• Synthetic: 10 points (synthetic vitamins, stabilizers, carrageenan, gums)
• Unknown: 3 points (default penalty if not specified)

Milk Type

Penalty Range: 0-15 points

The type of milk affects its nutritional profile:

• Whole milk: 0 points (best - full fat, minimally processed)
• Reduced fat (2%): 3 points (some fat removal)
• Low fat (1%): 5 points (significant fat removal)
• Skim/Fat-free: 8 points (all fat removed - most processed)
• Flavored: 15 points (chocolate, vanilla, etc. - added sugars and flavors)
• Unknown: 0 points (no penalty if unknown, assume whole)

Organic Certification

Penalty: Variable based on quality indicators

For non-organic milk, the penalty is reduced based on quality indicators:

Quality Indicators (each reduces the non-organic penalty):

• Pasture-raised: 25% reduction
• Grass-fed: 20% reduction
• Uses organic feed: 15% reduction
• Regenerative farming: 10% reduction
• No hormones: 10% reduction
• No antibiotics: 10% reduction
• Low pesticide risk: 5% reduction
• Raw milk (only when microbial evidence is verified on the product): 10% reduction

Full Penalty Waiver Conditions:

• Raw milk with verified microbial evidence and 4+ major quality indicators: 100% reduction (no penalty)
• Products with 3+ major indicators and quality score ≥60: 100% reduction
• Standard reduction: Proportional to quality score (up to 95%)

This ensures that high-quality non-certified farms aren't unfairly penalized when their practices exceed organic standards.

Packaging

Penalty Range: 0-15 points

Milk packaging materials are evaluated for potential chemical migration:

• Glass bottle: 0 points (safest option, no leaching)
• Cardboard/paper carton: 2-5 points (depends on inner lining)
• HDPE plastic: 10 points (moderate microplastic concerns)
• PET plastic: 12 points (higher microplastic shedding)
• Polystyrene: 15 points (worst - styrene exposure concerns)

Note: Glass bottles are the safest option for milk storage, particularly for raw milk where the product is consumed without heat treatment.

Special Considerations

A2 Milk

Products containing only A2 beta-casein protein may be noted but do not receive scoring bonuses or penalties. A2 milk is easier to digest for some individuals but doesn't affect overall health score.

Protein Type (A2/A2)

While A2 protein is tracked as a certification, it doesn't directly affect the score since both A1 and A2 milk can be high-quality depending on farming practices.

Raw Milk Considerations

Raw milk is scored like other milk on farming and quality inputs, but microbial risk is not “free.” Without documented pathogen or microbial screening on the product, we do not assume raw is safer or cleaner than pasteurized for scoring purposes. When producers publish credible batch or third-party testing, we can reflect lower processing-related penalty and include raw in quality-indicator relief.

Why this matters: Outbreaks and serious illness linked to raw milk are well documented; risk depends on the herd, hygiene, cold chain, and testing—not on the word “natural.” If you choose raw milk, that is a personal decision; Oasis does not provide medical or legal advice. Check local laws and guidance from CDC / FDA / your state or national health authority if you are unsure.

Score Interpretation

Score Ranges

• 90-100: Excellent - Pasture-raised, grass-fed, raw or minimally processed, minimal concerns
• 80-89: Good - High-quality practices with minor processing or certification gaps
• 70-79: Fair - Conventional organic or good practices with some concerns
• 60-69: Poor - Conventional milk with significant processing or welfare concerns
• Below 60: Very Poor - Highly processed milk with multiple concerns

Health Considerations

Nutritional Differences

Milk from well-raised cows can be significantly more nutritious. Compared to conventional milk, pasture-raised grass-fed milk typically contains:

• Omega-3: 2-5x higher
• CLA: 2-5x higher (anti-inflammatory)
• Vitamin A: 2x higher
• Vitamin E: 3x higher
• Beta-carotene: 7x higher (visible as yellow tint)
• Omega-6:3 ratio: ~2:1 (ideal) vs ~8:1 (inflammatory in conventional)

Raw Milk Benefits (when from quality sources)

• Enzymes: Contains lactase, lipase, phosphatase
• Beneficial bacteria: Natural probiotics
• Proteins: Undenatured whey proteins
• Vitamins: Heat-sensitive vitamins preserved (C, B12)

Common Concerns

• Raw milk and pathogens: Unpasteurized milk can harbor bacteria and other germs that cause severe or life-threatening illness; vulnerable groups are often told to avoid it entirely.
• Hormone residues: rBST increases IGF-1 levels in milk
• Antibiotic residues: Can contribute to resistance and gut microbiome disruption
• Pesticide residues: Accumulate in milk fat from contaminated feed
• Mycotoxins: From moldy grain feed
• Heavy metals: From contaminated soil/water
• Microplastics: From plastic packaging, especially with temperature changes

Best Practices

• Choose pasture-raised, grass-fed milk when possible
• If you use raw milk, prioritize traceable sourcing, strict cold chain, and published testing; understand risks and restrictions where you live
• Look for "rBST-free" or "no added hormones" labels
• Select glass bottle packaging when available
• Prefer organic to reduce pesticide and antibiotic exposure
• Avoid ultra-pasteurized or ultra-filtered when fresh options are available
• Check for farms that publish third-party testing results
• Be skeptical of marketing terms without certification
• Local milk from known farms often exceeds store-bought quality

Common Label Clarifications

Understanding milk labels can be confusing. Here's what each label means and how reliable it is:

Reliable Labels:

• Pasture-Raised: Cows have outdoor access to pasture (Good reliability if certified)
• Organic: USDA certified organic feed, no antibiotics, no hormones (Good reliability)
• Grass-Fed: Diet primarily consisting of grass (Good reliability if certified)
• Raw: Unpasteurized milk (Good reliability - regulated)

Moderate Labels:

• rBST-Free: No synthetic growth hormones (Moderate reliability - hard to verify)
• Hormone-Free: No added hormones (Moderate reliability)
• A2: Contains only A2 beta-casein (Moderate reliability - requires testing)

Unreliable Labels:

• Natural: No legal definition for milk (No reliability)
• Farm Fresh: Marketing term only (No reliability)
• Wholesome: Marketing term only (No reliability)

Limitations

• Scores reflect available information and certifications
• Small local farms may have excellent practices but lack formal certification
• Feed quality claims are often unverifiable
• Seasonal variations in pasture access are not captured
• Individual farm practices may vary within the same brand
• Testing frequency and methodology varies by producer
• Raw milk legality and safety varies by jurisdiction

Baby Formula Scoring Methodology

Everything is scored out of 100, and we penalize each item depending on several key factors. Baby formula scoring prioritizes infant safety above all other considerations.

Evaluation Factors

Our baby formula scoring system evaluates products based on the following criteria:

• Safety recalls - Active recall status (overrides all other scoring)
• Harmful ingredients - Problematic ingredients like palm oil, corn syrup, synthetic additives
• Ingredient severity - Per-ingredient safety analysis using food-grade guidelines
• Packaging - BPA-free status and recyclability
• Lab testing - Whether the product has verified lab reports

Scoring Components

Safety Veto (Recall Check)

Impact: Automatic score of 1 if triggered

Before any scoring begins, the system checks for active recalls:

• Active recall found: Score is forced to 1 (lowest possible)
• Recall ID present but record unverifiable: Score is forced to 1 (safety-first approach)
• No active recalls: Normal scoring proceeds

This safety-first approach ensures that no recalled formula product can receive a passing score.

Harmful Ingredients Assessment

Penalty Range: 0-35 points

Specific problematic ingredients are checked:

• Corn syrup: 15 points (nutritionally inferior sweetener, linked to metabolic concerns)
• Palm oil: 10 points (reduces calcium and fat absorption in infants)
• Synthetic additives: 10 points (artificial or synthetic ingredients)

Ingredient Severity Analysis

All ingredients are individually analyzed using food-grade safety calculations:

• Each ingredient receives a severity score based on health impact
• Food-specific guidelines (MADL) are used when available
• Contaminants receive enhanced scrutiny with higher multipliers
• The total penalty is capped to prevent scores below 1

Packaging Assessment

Penalty Range: 0-15 points

Formula packaging is evaluated for chemical safety:

• Not BPA-free: 10 points (BPA is an endocrine disruptor)
• Not recyclable: 5 points (environmental and material quality indicator)

Lab Testing

Penalty: 15 points if not tested

Products without verified lab reports receive a 15-point penalty, as third-party testing is critical for infant safety.

Score Interpretation

Score Ranges

• 90-100: Excellent - Clean ingredients, no recalls, safe packaging
• 80-89: Good - Minor concerns, generally safe for infants
• 70-79: Fair - Some ingredient concerns, consider alternatives
• 60-69: Poor - Significant issues, consult pediatrician
• Below 60: Very Poor - Major safety concerns, avoid
• Score of 1: Product has an active recall - do not use

Health Considerations

Common Concerns

• Recalls: FDA recalls for contamination, nutrient deficiency, or manufacturing issues
• Palm oil: Reduces calcium absorption and forms insoluble soaps in infant gut
• Corn syrup solids: Nutritionally inferior to lactose as primary carbohydrate
• Heavy metals: Lead, arsenic, cadmium, and mercury contamination
• BPA: Endocrine disruptor found in some packaging materials

Best Practices

• Always check for active recalls before purchasing
• Choose formulas with lactose as primary carbohydrate when possible
• Avoid palm oil when alternatives are available
• Select BPA-free packaging
• Look for formulas with DHA, ARA, probiotics, and prebiotics
• Prefer organic and non-GMO verified options

Cookware Scoring Methodology

Everything is scored out of 100, and we penalize each item depending on several key factors. Cookware safety is critical because materials are in direct contact with food at high temperatures, which can accelerate chemical leaching.

Evaluation Factors

Our cookware scoring system evaluates products based on the following criteria:

• Base material - Core material safety and composition
• Coating type - Surface coating safety and PFAS concerns
• Heat tolerance - Safe temperature range and thermal stability
• Leaching risk - Potential for chemicals to migrate into food
• Durability - Longevity and resistance to degradation
• Transparency - Manufacturer disclosure and testing

Scoring Components

Base Material Safety

Penalty Range: 0-40 points

The base material is the most critical factor for cookware safety:

Safest Materials (0 points)

• 18/10 stainless steel: High chromium and nickel content, corrosion resistant
• 100% ceramic: No chemical coatings, excellent heat distribution
• Borosilicate glass: Completely inert, no leaching
• Enameled cast iron: Protective enamel coating over cast iron

Moderate Concern (10-20 points)

• 18/0 stainless steel: ~15 points (lower corrosion resistance, potential nickel leaching)
• Silicone: ~15 points (generally safe but some quality concerns)

Higher Concern (20-35 points)

• Anodized aluminum: ~27 points (oxidized layer reduces but doesn't eliminate aluminum leaching)

Highest Concern (40 points)

• Bare aluminum: Reactive metal, leaches into acidic foods
• Unlined copper: Toxic copper leaching into food
• PTFE-based (with PFAS): Forever chemicals that degrade at high temperatures

Coating Safety

Penalty Range: 0-40 points

Safe Coatings (0 points)

• No coating: Bare cast iron, carbon steel, stainless
• 100% ceramic: Traditional ceramic glaze
• Lead-free enamel: Protective vitreous coating

Moderate Concern (5-15 points)

• PFAS-free ceramic nonstick: ~10 points (generally safe but less durable)
• Sol-gel ceramic: ~10 points (newer technology, limited long-term data)

High Concern (30-40 points)

• PTFE (Teflon): ~35 points (releases toxic fumes above 500°F, contains PFAS)

• Below 400°F / not oven safe: 17 points (PTFE, some nonstick coatings)

Note: PTFE coatings begin to decompose above 500°F, releasing toxic fumes that can cause polymer fume fever.

Leaching Risk

Penalty Range: 0-20 points

• Glass, carbon steel, cast iron: 0 points (minimal leaching)
• 18/10 stainless, anodized aluminum, copper-lined: 2 points (very low risk)
• 18/0 stainless, tested ceramic: 7 points (moderate risk)
• Bare aluminum, unlined copper, scratched PFAS: 17 points (high leaching risk)

Durability

Penalty Range: 0-10 points

Durability matters because degraded cookware leaches more chemicals:

• Cast iron, carbon steel, stainless steel: 0 points (lasts generations)
• Ceramic nonstick: 6 points (degrades within 1-3 years)
• PTFE (Teflon): 10 points (chips and peels, releasing particles into food)

Transparency

Penalty Range: 0-10 points

• Full disclosure + testing: 0 points
• Partial disclosure: 3 points
• Generic claims only: 7 points

Health Considerations

Honey Fraud

Honey is one of the most adulterated foods in the world:

• Ultra-filtering removes pollen, making origin untraceable (used to launder Chinese honey)
• Corn syrup blending is common in low-cost honey products
• "Honey blend" labels indicate the product is not pure honey
• True Source Certified is the best indicator of authentic honey

Maple Syrup vs. "Pancake Syrup"

• Pure maple syrup is made from maple tree sap with minimal processing
• "Pancake syrup" or "maple-flavored syrup" is typically corn syrup with caramel color and artificial flavor
• Check the ingredient list: real maple syrup should have ONE ingredient

Common Concerns

• HFCS: Linked to obesity, fatty liver disease, and metabolic syndrome
• Artificial sweeteners: Emerging research on gut microbiome disruption
• Maltodextrin filler: Glycemic index of ~100 (higher than table sugar)
• Caramel color: May contain 4-MEI, a possible carcinogen
• Plastic containers: Chemical leaching, especially with viscous products

Best Practices

• Choose raw, local honey from a single source
• Verify honey authenticity with True Source Certification
• Buy real maple syrup (check for single ingredient)
• Avoid products labeled "blend", "flavored", or "product"
• Choose glass containers over plastic
• Prefer organic options to reduce pesticide exposure
• Read ingredient lists carefully — quality sweeteners need minimal ingredients
• If using stevia or monk fruit, choose pure extracts without maltodextrin filler

Limitations

• Scores reflect available certifications and ingredient disclosures
• Honey adulteration testing is not universally available
• Raw honey carries a small botulism risk for infants under 12 months
• Individual glycemic responses to sweeteners vary
• Taste preference is not evaluated
• Environmental impact of sweetener production is not scored

Tea Products Scoring Methodology

Everything is scored out of 100, and we penalize each item depending on several key factors. Tea products receive particularly strict evaluation because tea bags are steeped in hot water — a process that dramatically accelerates microplastic shedding and chemical leaching from packaging materials.

Evaluation Factors

Our tea scoring system evaluates products based on the following criteria:

• Lab verification - Third-party testing for contaminants (critical)
• Contaminants - Heavy metals, pesticides, and other harmful substances
• Tea bag material - Microplastic shedding and chemical leaching potential
• Organic certification - Pesticide residue concerns
• Certifications - Additional safety certifications

Scoring Components

Lab Verification

Penalty: Up to 70 points if missing

Tea products require comprehensive lab reports:

• Full lab report available: 0 points
• No lab report (category weighted on ingredients/packaging): 15 points
• No lab report (standard category): 70 points (max score of 30)
• No lab report + other SKU has contaminants: 20 points

Contaminant Penalties

Penalty Range: Up to 80 points total

All tea ingredients/contaminants are individually analyzed:

• Each contaminant receives a severity score based on health impact
• Contaminants with guidelines and measured amounts use multiplier-based scaling
• Contaminants over guidelines receive amplified penalties (up to 8x for contaminants)
• Harmful non-contaminant ingredients receive 3x severity multiplier

Tea Bag Material

Penalty Range: 0-40+ points per material

Tea bag material penalties are among the highest in our system because of direct contact with boiling water:

Highest Concern

• Nylon: 40 points (releases billions of micro/nanoplastics when steeped)
• Polyester: 40 points (similar to nylon — synthetic polymer shedding)
• Polypropylene: 35 points (heat-seal material on many bags)
• Polyethylene: 35 points (plastic seal material)

Moderate Concern

• Unknown material: 25 points (unverified = assume risk)

Low Concern

• Polylactic acid (PLA): 5 points (plant-based plastic, lower shedding)
• Plant-based materials: 5 points
• Paper: 5 points (minimal concern)
• Cellulose: 5 points (natural fiber)

No Concern

• Cotton: 0 points
• Silk: 0 points

Multiple Materials

When tea bags contain multiple materials, a 20% reduction is applied to avoid excessive double-penalization.

Microplastic-Free Certification

Products certified as microplastic-free have their packaging penalty removed entirely (0 points).

Organic Certification

Penalty: Variable if missing

Tea categories that require organic certification receive a 25-point penalty if the product lacks organic certification. Tea is a particularly high-risk crop for pesticide residues.

Certification Bonuses

Products with verified certifications receive score bonuses applied through the certification system.

Score Interpretation

Score Ranges

• 90-100: Excellent - Lab tested, clean results, safe packaging, organic
• 80-89: Good - Tested with minor concerns, safe materials
• 70-79: Fair - Some contaminant concerns or non-organic
• 60-69: Poor - Moderate contamination or unsafe tea bag materials
• Below 60: Very Poor - Major concerns or untested
• Below 30: Not lab tested — insufficient data for reliable scoring

Health Considerations

Tea Bag Microplastics

Research has shown that a single plastic tea bag steeped at 95°C can release:

• 11.6 billion microplastics
• 3.1 billion nanoplastics

These particles are small enough to penetrate cells and accumulate in organs. Common tea bag materials (nylon, PET, polypropylene) all shed significant microplastics when exposed to hot water.

Common Concerns

• Heavy metals: Lead, cadmium, and arsenic accumulate in tea leaves from soil
• Pesticide residues: Conventional tea farms use significant pesticide applications
• Microplastics: Released from synthetic tea bags during steeping
• Fluoride: Tea plants naturally accumulate fluoride from soil
• Mycotoxins: Can develop during improper storage
• Bleached tea bags: Paper bags may contain chlorine bleaching residues

Best Practices

• Choose loose leaf tea to avoid tea bag materials entirely
• If using tea bags, select cotton, silk, or cellulose-based bags
• Avoid nylon, polyester, and polypropylene tea bags
• Buy organic tea to reduce pesticide exposure
• Look for brands with published lab reports
• Prefer brands with microplastic-free certification
• Steep at appropriate temperatures (not all teas need boiling water)
• Choose reputable tea brands that test for heavy metals
• Store tea properly to prevent mycotoxin growth

Limitations

• Scores heavily depend on lab report availability
• Tea bag material information is not always disclosed
• Heavy metal content varies by growing region and soil conditions
• Steeping temperature and duration affect actual exposure levels
• Individual sensitivity to contaminants varies
• Beneficial compounds in tea (antioxidants, L-theanine) are not scored
• Water quality used for brewing also affects safety
