"A spark source mass spectrometer that uses electronic detection and a dedicated data analysis system was applied to a survey type trace analysis for chemical elements. Errors in the data system software were identified and corrected. Modifications to the system permit identification and quantitation of 72 elements at the aprt per billion level in water samples.""--P ii.

An excellent introduction to the real world of environmental work, this book covers all phases of data collection, (planning, field sampling, laboratory analysis, and data quality assessment), and is a single source comprehensive reference for the resolution of the most common problems that environmental professionals face daily in their work. (Midwest).

This comprehensive reference combines sampling and analysis of wildland water in one text. It includes sampling techniques for precipitation, surface water, and ground water. Analytical techniques for common water quality constituents are described. - Step-by-step laboratory procedures for measuring pH, conductivity, solids turbidity, alkalinity, and hardness - End-of-chapter reviews with study questions and key words - Review of solution chemistry - Detailed field sampling procedures and program design
