Water Safety Risk Calculator

Water Safety Risk Assessment Tool

This tool helps assess the food safety risk level of water based on source, treatment, and storage parameters.

Water Source:

Municipal / Treated Supply
Private Well / Groundwater
Surface Water (River, Lake)
Rainwater Harvested

Treatment Level:

Advanced (RO, UV + Filtration + Chlorination)
Standard (Chlorination + Filtration)
Basic (Boiling or Simple Filtration)
None / Untreated

Storage Condition:

Sealed / Sanitary Tank
Covered but Not Sealed
Open Container / Exposed

Intended Use:

Food Ingredient / Direct Contact
Processing Aid (Washing, Cleaning)
Non-Food (Cooling, Sanitation Only)

Calculate Risk Score

function calculateRisk() { const sourceRisk = { municipal: 1, well: 3, surface: 4, rainwater: 3 }; const treatRisk = { advanced: 0.5, standard: 1, basic: 3, none: 5 }; const storageRisk = { sealed: 0.5, covered: 2, open: 4 }; const usageRisk = { ingredient: 3, processing: 2, nonfood: 1 };

const source = document.getElementById('water-source').value; const treatment = document.getElementById('treatment').value; const storage = document.getElementById('storage').value; const usage = document.getElementById('usage').value;

const score = (sourceRisk[source] + treatRisk[treatment] + storageRisk[storage]) * usageRisk[usage]; const resultDiv = document.getElementById('result'); resultDiv.style.display = 'block';
