QUALITY OF WATER BRANCH TECHNICAL MEMORANDUM NO. 85.12

Subject:  PROGRAMS AND PLANS--Water Quality Laboratory 
                              Services Catalog for Fiscal
                              Year 1985

We are pleased to belatedly forward a hard copy of the 1985 
Water Quality Laboratory Services Catalog.  The format has 
been simplified for convenience in preparing requests for 
analytical services, the Glossary has been expanded, and 
explanatory material made more specific.  Lastly, the several 
thousand entries in the catalog have been thoroughly checked 
to eliminate errors.

Special attention is directed to recently approved 
methodology permitting us to offer the following 
determinations which have greatly improved detection 
limits:

    1.  Anions, bromide, chloride, fluoride, orthophosphate 
    and sulfate, ion-exchange chromatographic, low-ionic 
    strength waters, reporting level 0.01 mg/L, Schedule 
    0520.

    2.  Metals, cadmium, chromium, copper, lead, manganese, 
    nickel, thallium and zinc, atomic absorption 
    spectrometric, graphite furnace, reporting level 
    0.2 ug/L, Lab Codes 1250-57 and 492.

    3.  Alumium and boron, atomic emission spectrometric 
    dc plasma, reporting level 10 ug/L, Lab Codes 1265 and 
    1183.

The new catalog should be placed in the white binder 
previously furnished, using the dividers forwarded with the 
catalog.  If a new binder is needed, it may be requested from 
either the Atlanta or Denver Laboratory.

Suggestions for improvements to the catalog are always 
welcome.
