Water Bacteriology & Chemical Analysis

The Water Bacteriology & Chemical Analysis test at Pamel Laboratories is a comprehensive assessment of water quality, designed to evaluate both its microbiological safety and chemical composition. This test is essential for drinking water, boreholes, industrial water supplies, packaged water, and environmental water sources to ensure they meet health and regulatory standards.

It helps detect harmful microorganisms and assess the chemical balance of water to determine if it is safe for human consumption, domestic use, or industrial applications.

What the Test Includes:

1. Bacteriological Analysis:

• Total coliform count

• Faecal coliform (E. coli)

• Heterotrophic plate count

• Detection of disease-causing bacteria indicating contamination

2. Chemical Analysis:

• pH (acidity/alkalinity)

• Turbidity

• Hardness (Calcium & Magnesium)

• Iron (Fe)

• Nitrate (NO₃⁻)

• Chloride (Cl⁻)

• Sulphate (SO₄²⁻)

• Fluoride (F⁻)

• Total dissolved solids (TDS)

• Conductivity

Purpose of the Test:

• Ensure potability of drinking water

• Assess borehole, well, or packaged water quality

• Monitor water treatment systems for compliance and effectiveness

• Detect microbial contamination that may cause disease

• Verify chemical parameters against WHO or NAFDAC standards

Sample Type: Water sample in a sterile, tightly sealed container (minimum 1 liter recommended)

• Best collected from the source or point of use

• Must be transported promptly to the lab to preserve accuracy

Turnaround Time:

• Bacteriology: 24–48 hours

• Chemical analysis: 3–5 working days

Preparation Instructions:

• Use sterile containers provided or approved by the lab

• Label sample clearly with source, date, and time of collection

• Avoid contamination during sampling
