Philippine Clean Water Act Flashcards
An act providing for comprehensive water quality management and for other purposes
Philippine Clean Water Act of 2004 or RA 9275
requires the initial
and periodic examination of drinking water to be done by a DOH-accredited water testing laboratory.
PD No. 856 or Code of Sanitation of the Philippines
governing agency attached to East Avenue Medical Center
National Reference Laboratory for Environmental, Occupational Health, Toxicology and
Micronutrient Assay (NRL-EOTHM)
Objective of A0 No. 2020-0031
accreditation of laboratories for drinking water analysis to be able to generate accurate and reliable results
refers to an individual, partnership, corporation or association seeking a certificate of accreditation to maintain a laboratory for drinking water analysis.
Applicant
refers to a formal authorization issued by the DOH to an
individual, partnership, corporation or association seeking to perform drinking water analysis in
compliance with the requirements prescribed in this Order. In this Order, accreditation shall mean
licensing
Certificate of Accreditation (DOH-COA)
— refers to a facility that performs any or combination of these analyses: microbiological, physical, and chemical analysis, to determine the potability and safety of drinking water.
Laboratory for Drinking Water Analysis (LDWA)
refers to he highest level of a contaminant that is allowed in
drinking-water.
Maximum Allowable Level (MAL)
refers to a list of minimum legally enforceable core parameters offered by a laboratory for drinking water analysis which are as follows: Lead, Nitrate, Arsenic, Cadmium, color, turbidity, thermotolerant coliform (E.coli), disinfectant residual, pH,Total Dissolved Solids (TDS).
Mandatory Parameters
— refers to the bases for the standards for drinking-water quality, water sampling, and examination and evaluation of results.
Philippine National Standards for Drinking Water (PNSDW)
—refers to documents that state the quality policy, describe the quality system and quality procedures intended forthe overall planning and administration of activities, which affect the
quality of laboratory services
Quality Manual
refers to statements of intentions or desires of the organization with respect to
management of their quality system.
Quality Policy
— refers to the collected drinking water sample submitted for analysis.
Water Sample
refers to a testing procedure/s performed for the determination of microbiological,
physical, and chemical qualities of drinking water
Water Analysis
Operated and maintained partially or wholly by the national, provincial, city or
municipal government, or other political unit, or by any department, division, board, or agency
thereof
Government
privately owned , established and operated with funds through donation, principal,
investment or other means, by any individual, corporation, association or organization.
Private
— a laboratory that is located within the premises and operates as part of
a DOH licensed health facility.
Institution based
a laboratory that operates independently and is not attached to
any DOH licensed health facility.
Non-institution based —
Chemical Laboratory General Requirements
- Refrigerator
- Thermometer/thermohygrometer
- Analytical balance
- Distilling or water purification system
- Fume hood
Used to measure the light transmitted by a solution to determine the concentration of the light-absorbing substance in the solution
Spectrophotometer
Microbiological Laboratory General Requirements
Autoclave

- Hot plate with magnetic stirrer
- Oven sterilizer
- Water bath (44.5 C)
- Incubator (35 C)
- Distilling apparatus / water purifier
- Bacticinerator

- Thermometer
inhibit the growth of gram-positive bacteria including lactose fermenting
Clostridia
Oxbile and brilliant green
Production of gas lactose fermentation is detected by incorporating inverted Durham’s tube,
indicates a positive evidence of faecal coliforms
Total Coliform Test: Brilliant Green Lactose Broth
- Tryptose provides the nitrogen, carbon compounds, vitamins and amino acids.
- Lactose is the fermentable sugar
- Sodium lauryl sulphate inhibits organisms other than coliforms
- Bile salts inhibit gram-positive bacteria especially bacilli and faecal Streptococci
- Sodium chloride maintains the osmotic balance of the medium.
- Potassium phosphates control the pH
- A positive indole test in a broth tube showing gas production at 44°C indicates the presence of
Escherichia coli
Total Coliform Test: Laryl Tryptose Broth (LTB)
- Tryptose or Casein provides essential growth nutrients
- Bile salts inhibit gram-positive bacteria especially bacilli and faecal Streptococci.
- Sodium Chloride maintains the osmotic balance of the medium
- Potassium phosphates control the pH during fermentation of lactose Lactose-positive bacteria
metabolize lactose with gas formation
Thermotolerant Coliform Test: EC Broth Medium
Laboratory reports for chemical analysis shall be certified by the registered chemist and shall bear the
registered chemist’s seal or the seal of the registered chemist
All accredited LDWA must participate in
Annual Proficiency Testing
Annual proficiency testing is conducted every
3 years
Who conducts the annual proficiency testing
NRL-EOHTM
HFSRB/CHD-RLED may immediately impose preventive suspension, which shall no be more than
60 days
provides the nitrogen, carbon compounds, vitamins and amino acids
