1 <br />' NCEC - 1990 HYDROLOGY REPORT <br />' above. As previously recorded, wells OW-3L, 7, 12, and 13 remain <br />dry. <br />' Hydrographs for OW-8, and 14 are included. Water levels measured <br />' throughout the 1990-91 season are consistent with previous trends <br />noted on the hydrographs. However, compared to previous data, <br />periods of significant recharge as reflected by relatively high <br />' water levels, were not evident during 1990. This is probably due <br />to drier conditions during 1990 relative to previous years. <br />' The annual chemical analyses appear to be consistent with <br />' previously collected data. <br />' 2.3 &uture Places <br />' The present quarterly/annual monitoring schedule will continue <br />until activity resumes at the NCEC facility. As stated in previous <br />' hydrologic reports, several plans will be implemented in order to <br /> maintain the quality and reliability of the collected data.
