5 7 ENVIRO-CHEM SECTION The Environmental-Chemistry Section (Enviro-Chem) consists of three fully equipped environmental and chemical testing laboratories certified by the State of California. These labs perform analysis on materials including wastewater, industrial waste, and solids using EPA approved methods. The labs provide testing to satisfy the requirements of local, state, and federal programs such as Title 22, UST, and NPDES. CHEMICA L LABORATORY analyzes for tradition al w astew ater constituents such as total and fecal coliform, BOD, cyanide, phenols, nitrogen compounds, and anions (chloride, fluoride, etc.) The solid materials tested include cement, soil, aggregate, concrete, lime slurry.
6 INORGANIC LABORATORY analyzes samples for over tw enty-five metals including lead, selenium, mercury, and arsenic. ORGANIC LABORATORY tests for more than 150 constituents including benzene, toluene, chloroform, and DDT. Analyses performed include VOC, PCB, BNA and other semi-volatile organic compounds, pesticides, as well as gasoline and diesel range petroleum hydrocarbons. SUPPORT UNITS MA NAGEMEN T I NFOR MATIO N SYS TEMS maintains and enhances information systems and lab automation for the Division . ADMI NIS TRATIVE UNIT supports Standards operational sections in personnel management, cost accounting, billing and time keeping functions.

COMPACTIO N LABORATORY tes ts s oils f or r elative c ompac tion. Cer tif ied personnel conduct field in-place density tests using both the nuclear gauge and sand cone methods.
8 Soil is tested for lab maximum density and optimum moisture content, which in turn are used to compare with field density and moisture content to determine relat ive compaction and optimum moisture content.

10 13 CONSTRUCTION SECTION The Construction Section consists of five units that provide testing Services on construction materials and also drilling and coring Services . ROADS & HIGHWAYS GROUP consisting of Pavement Evaluat ion and Asphalt Laboratory provides complete Services for road construction, reconstruction and maintenance. All phases from planning, evaluat ion, design, mix design, construction monitoring, and quality control are supported. PAVEMENT EVALUATION provides Nondestructive Deflection Testing Services for use in pavement structural evaluat ion and overlay design for flexible and rigid pavement. This lab also provides core sampling on pavement and wall structures.
