Reconnaissance Investigation of Water Quality, Bottom Sediment, and BiotaAssociated with Irrigation Drainage in the Middle Rio Grande Valley and Bosque Del Apache National Wildlife Refuge, New Mexico, 1988-89

摘要

The Middle Rio Grande Project and Bosque del Apache National Wildlife Refuge(herein referred to as the Refuge or BDANWR) reconnaissance study was selected by the DOI Task Group as one of 10 irrigation-drainage studies to be conducted during water years 1988 and 1989. The purpose of the report is to present information for determining if chemical constituents in the water, sediment, and biota associated with irrigation drainage in the USBR's Middle Rio Grande Project area and the BDANWR are potentially harmful to human health, wildlife, and fish, or other beneficial uses. Middle Rio Grande data from other studies and from the files of the USGS, USBR, and USFWS are included in the report. Reconnaissance water and bottom-sediment samples and resident biota were collected from the BDANWR for laboratory chemical analyses because available data were deemed inadequate for assessing water-quality conditions that may be associated with irrigation drainage at the BDANWR. Selected data are summarized and compared with criteria, standards, or data from other related studies for determining if harmful levels of chemicals are present in the irrigation-drainage water.
