Peak horizontal acceleration and velocity from strong motion records including records from the 1979 Imperial Valley, California, earthquake
William B. Joyner, David M. Boore, Ronald L. Porcella
1981, Open-File Report 81-365
We have taken advantage of the recent increase in strong-motion data at close distances to derive new attenuation relations for peak horizontal acceleration and velocity. Acceleration data from 183 recordings of 24 earthquakes and velocity data from 62 recordings of 10 earthquakes have been used. This new analysis uses a...

Determination of pentachlorophenol in water and aquifer sediments by high-performance liquid chromatography
D.F. Goerlitz
1981, Open-File Report 82-124
Methods for the determination of pentachlorophenol (PCP) in water and aquifer sediments are presented. Reverse-phase high-performance liquid chromotography employing ion suppression and gradient elution is used. PCP can be determined directly in water at a lower limit of detection Of 0.2 micrograms per liter. For extracts of sediment, PCP can...
