Laboratory Assessments

• 30 Public sector laboratories
• 30 Private sector laboratories

12
Laboratory Assessment

• Sufficient capacity
• Basic microbiology
• Basic chemistry
• Nitrite
• Cations
• Aluminium, iron, manganese, copper, lead, nickel,
  cadmium, chromium
• Trihalomethanes, trichloroethene,
  tetrachloroethene
• Note most labs do not have validated methods

13
Laboratory Assessment

• Insufficient capacity
• Cyanide
• Total organic carbon
• Bromate
• Sodium
• Boron
• Arsenic, selenium, antimony, mercury
• Benzene, 1,2 dichloroethene
• Polycyclic aromatic hydrocarbons
• Pesticides
• Radioactivity
• Sub-contract analysis at least in the short term

Recommendations

• Sanitary Authorities
• Adopt the DWNMP
• Sub-contract specialist analysis in the short
  term
• Review SA Reports on a routine basis and update
  as necessary
• Review all small schemes, including Group and
  Private schemes, to determine Regulatory status
  by virtue of water being supplied as part of a
  commercial or public activity

18
Recommendations

• Laboratory Capacity Provision of Laboratory
  Sampling Services
• Establish National laboratory for specialist
  analysis and use 7 regional labs for
  time-dependent analyses
• Sub-contract radioactivity analysis to RPII
• All laboratories samplers be accredited

19
Recommendations

• Rationalisation
• RWNMP should continue
• RWNMP should piggyback on DWNMP
• Because monitoring burden is high, consideration
  should be given to amalgamating schemes
