3 Abstract This document reports data obtained within the hydro monitoring program, which is one of the activities performed within the site investigation at Forsmark. The objective of the groundwater monitoring is to support the hydrogeological characterization of the area and to document the groundwater conditions before a possible excavation. Data presented in this report are collected during the period of April 7 until April 8 and include groundwater levels in surface boreholes and groundwater pressure in boreholes situated in the SFR-tunnel. Meteorological and hydrological data and some service parameters, which have been collected within this activity as well, are presented elsewhere. The data collecting system in HMS (Hydro Monitoring System) consists of measurement stations (computers) which communicate with and collect data from a number of dataloggers. The computers are connected to the SKB Ethernet LAN. All data are collected by means of different transducers connected to different types of data loggers: Minitroll, LevelTroll, Mitec and Datataker. In order to calibrate registrations from the data loggers, manual levelling of all surface borehole sections is made, normally once every month. The logger data are converted to water levels using calibration constants. All collected data are quality checked once every three months. During this work, obviously erroneous data are omitted and calibration constants are corrected so that the monitored data comply with the manual levelling. At these occasions the status of the equipment is also checked and service might be initiated. Diagrams of groundwater levels and groundwater pressure for the period of April 7 April 8 (one data point per section and twenty-four hours) are presented in Appendix. The original data are stored in the primary data base Sicada. The data in this data base may then be used for further analysis. There are no nonconformities with respect to the activity plan or the method description.

4 Sammanfattning Denna rapport redovisar data erhållna inom programmet för grundvattenmonitering vilket är en av aktiviteterna inom platsundersökningen i Forsmark. Syftet med grund-vattenmoniteringen är att stödja den hydrogeologiska karakteriseringen av platsen och att dokumentera grundvattenförhållanden före en eventuell tunneldrivning för ett djupförvar. Data presenterade i rapporten är insamlade under perioden april 7 till och med april 8 och består av grundvattennivå i ytborrhål samt grundvattentryck i borrhål belägna i SFR-tunneln. Inom ramen för platsundersökningarna insamlas även meteorologiska och ythydrologiska data, vilka dock presenteras i andra rapporter. Datainsamlingssystemet i HMS (Hydro Monitoring System) består av mätstationer (datorer) vilka kommunicerar med och samlar in data från ett antal dataloggrar. Datorerna är förbundna med SKB:s nätverk. Alla data samlas in med hjälp av givare förbundna med olika typer av dataloggrar: Minitroll, LevelTroll, Mitec och Datataker. För att kunna kalibrera registreringarna från dataloggrarna utförs, vanligtvis en gång i månaden, manuell nivåregistrering (lodning) i alla sektioner i ytborrhålen. Loggerdata omvandlas till vattennivåer genom applicering av kalibreringskonstanter. Alla insamlade data kvalitetskontrolleras en gång i kvartalet. Under detta arbete tas uppenbart felaktiga data bort och kalibreringskonstanterna korrigeras så att automatiskt registrerade data överensstämmer med manuella nivåregistreringar. Vid dessa tillfällen kontrolleras utrustningens status och service kan initieras. Diagram över grundvattennivåer och grundvattentryck för perioden april 7 april 8 (en datapunkt per sektion och 4 timmar) visas i Appendix. Originaldata lagras i primärdatabasen Sicada. Data från denna databas kan användas för vidare analyser. Aktiviteten har utförts i överensstämmelse med aktivitetsplanen och metodbeskrivningen. 4

7 Objective and scope The objectives of the part of the hydro monitoring program presented in this report are to determine baseline conditions of the natural variations of the groundwater levels prior to the potential excavation for a nuclear waste repository and to support the hydro-geological site characterisation. Data collected within this activity are: groundwater level in surface boreholes (including core- and percussion drilled boreholes in solid rock and monitoring wells in soil), groundwater pressure in boreholes situated in the SFR-tunnel, water level, water temperature and electrical conductivity of surface waters measured in flumes at runoff stations, although presented elsewhere, meteorological data from SMHI (Swedish Meteorological and Hydrological Institute), although presented elsewhere. There are also some parameters that are used for monitoring the hardware performance and the environment in which the hardware is used. However, these parameters are not reported herein. The following numbers of boreholes, monitoring wells in soil and surface water level gauges were included in the Forsmark monitoring system at the end of April 8: 5 core-drilled surface boreholes, 7 percussion-drilled surface boreholes, 5 monitoring wells in soil, 6 surface water level gauges, core-drilled boreholes in the SFR-tunnel. The locations of the boreholes are shown in Figure -. Coordinates of all boreholes in the reference system RT9.5 gon V : 5 and elevation at top of casing (TOC) are provided in Sicada. 9

11 . Data collection system The data collection system, which is part of the Hydro Monitoring System (HMS), consists of measurement stations (computers), which collect data from a number of data sources, see Figure -4. The computers are connected to the SKB Ethernet LAN (Local Area Network). All data are collected by means of pressure transducers connected to different types of data loggers or by manual levelling. The following data loggers are used: Minitroll: a single-channel data logger of stand-alone type where the transducer is integrated in the logger. The logger is submerged in the groundwater and has the capacity to store 8, data. Leveltroll: the successor to Minitroll, which is no longer manufactured. It is a logger that in most respects is equal to Minitroll, but has the capacity to store 5, data. Mitec: a data logger connected on-line by means of GSM telephony. A pressure transducer of the type Druck PTX is connected to the logger. Only the transducer is submerged in the groundwater. The logger has eight channels, but during monitoring in boreholes, only one channel is used for pressure monitoring and one for monitoring of the battery voltage. Datataker: a data logger connected on-line by means of radio or network. The logger has 4 channels and is used only for monitoring in percussion- and core-drilled boreholes.

12 4 Execution 4. General Data are collected to the measurement system, HMS, as described in Chapter. The on-line system is designed to handle short interruptions in the communication. Data can be stored for at least a couple of hours in the loggers. All data are finally stored in the measurement station. Tape backup is made of all data. Monitored data that have been quality assured are transferred quarterly to the site characterization database, Sicada. 4. Field work Manual levelling is generally carried out once a month in the surface boreholes. At the same time, the equipment is checked and maintenance is performed. All data from stand-alone type loggers are manually dumped into a portable PC and then transmitted to the measurement station, normally once every three months. 4. Data handling 4.. Calibration method for surface boreholes Manual levelling of all surface borehole sections is made, normally once every month, in order to calibrate the registrations from the data loggers. The logger data from the surface boreholes are converted to water levels by means of a linear calibration equation. It is also necessary to subtract the air pressure since all transducers give the absolute pressure. Converted logger data are compared with results from manual levelling. If the two differ, calibration constants are adjusted until an acceptable agreement is obtained. 4.. Calibration method for tunnel boreholes A pressure reference system is installed in the SFR-tunnel. It consists of two pressure tanks located at two different tunnel depths, generating one high and one low pressure of known magnitude. From these tanks, tubes are connected to each of the four measurement stations in the tunnel. At each station, a number of transducers are mounted on a panel where the tubes from the pressure reference system also are available to enable in situ calibration of the pressure transducers. During calibration all transducers on the panel are connected to the reference system together with a mobile pressure transducer that is used for very accurate measurements of the high and the low pressure, respectively. From these measurements a linear calibration equation is calculated. 5

13 4.. Recording interval For stand-alone and GSM-connected data loggers, measurements of the groundwater level are normally made with five minutes intervals. For all other data loggers connected on-line, levels are normally measured once every ten minutes. Measured values are not stored unless they differ from the previously stored value by more than. m ( kpa) for percussion- and core-drilled boreholes, and.5 m for monitoring wells in soil. In addition to this, a value is stored every two hours. 4.4 Quality assurance Once every week, an inspection of all collected data is performed. The purpose of this is to verify that all loggers are sending data and that all transducers are functioning. Quarterly, all data collected are subject to a quality check. During this Q/A, obviously erroneous data are omitted and calibration constants are corrected so that the monitored data comply with the manual levelling data (see Section 4..). At this occasion, the status of the equipment is also checked and service might be initiated. 4.5 Nonconformities There are no nonconformities with respect to the activity plan or the method description. 6

14 5 Results 5. General Original data from the reported activity are stored in the primary database Sicada. Data are traceable in Sicada by the Activity Plan number (AP PF 4-7- and AP PF 4-7-5). Only data in databases are accepted for further interpretation and modelling. The data presented in this report are regarded as copies of the original data. Data in the databases may be revised, if needed. However, such revision of the database will not necessarily result in a revision of this report, although the normal procedure is that major data revisions entail a revision of P-reports. Minor data revisions are normally presented as supplements, available at 5. Groundwater levels Monitored borehole sections are listed in Appendix. Diagrams of groundwater levels and groundwater pressure are presented in Appendix. All levels in the diagrams are given as metres above sea level in the national elevation system (RHB7). Data from previously reported periods are to be found in earlier reports //, //, // or /4/. Daily values are presented for each section in the diagrams. The data point shown is the first stored data point after midnight. When registrations are missing, manually levelled data, if available, are inserted. Boreholes included in the monitoring system in Forsmark and SFR: Core-drilled boreholes (5): KFMA D, KFMA B, KFMA B, KFM4A, KFM5A, KFM6A C, KFM7A C, KFM8A D, KFM9A B, KFMA, KFMA, KFMA Percussion-drilled boreholes (7): HFM HFM5, HFM7 HFM8 Monitoring wells in soil (5): SFM, SFM SFM6, SFM8, SFM SFM5, SFM7, SFM9, SFM SFM, SFM5 SFM8, SFM, SFM, SFM4, SFM6, SFM49, SFM57, SFM58, SFM6, SFM6, SFM67 SFM7, SFM75, SFM77 SFM8, SFM84, SFM87, SFM9, SFM95, SFM4 SFM7 Surface water level gauges (6) SFM8 (=PFM8) SFM4, SFM64 SFR boreholes (): KFR KFR5, KFR7A B, KFR8, KFR9, KFR, KFR9, KFR55, KFR General comments Results from monitoring in boreholes are presented in diagrams. Level data and pressure data from all sections in each borehole are presented for the period of April 7 until April 8. 7

15 The symbols used in the diagrams are: The lowermost section = Section Section Section Section 4 Section 5 Section 6 Section 7 Section 8 Section 9 Section Sometimes it is difficult to differentiate registrations from individual sections in the diagrams. However, since the main purpose of this report is to present an overall view of the long-term changes, it was not found advantageous to show more detailed diagrams from individual sections. Detailed diagrams during test periods are presented in reports from the different tests. Due to failures in the mechanical or electronic equipment, data are sometimes missing for longer or shorter periods. This is not commented on below. For more comments on the diagrams, see Site investigation Internal Reports, Table -. Remarks are given when the registration for some reason has a deviating appearance. When registrations are missing, manually levelled data, if available, are inserted. In many boreholes, the groundwater level shows large and rapid variations. This is often due to activities such as pumping, water sampling, tracer tests etc. Packers may deflate due to leakage, which can be difficult to discover. If a section in a borehole suddenly shows a pressure that is close to the pressure in a neighbouring section, the reason might be deflated packers. 5.. Comments on some of the diagrams In most of the percussion- and core-drilled surface boreholes, more or less pronounced drawdowns in the groundwater level can be seen during summer and autumn 7. This is due to the pumping performed in HFM4 described further below. The groundwater in many of the monitoring wells in soil has been reported to be frozen in December 7 through March 8. Obviously erroneous data due to freezing have been eliminated. HFM4: Pumping (5 L/min) was performed in the borehole from the end of June to the beginning of October 7 and also from the end of November to the middle of December 7. HFM: Pumping (6 L/min) was performed in the borehole from the beginning to the middle of November 7. HFM4: After installation of packers in the borehole in July 6, section has always been reported to be dry and all data have been omitted. Measurement in section was terminated in May 7. 8

16 KFMA, KFM6A and KFM8A: The anomalous behaviour for section one in KFMA and KFM6A and section in KFM8A is caused by low transmissivity and/or poor communication between the standpipe and the section in combination with a relatively large difference between the stand-pipe level and the pressure in the borehole section. When the mini-packer is released, in connection to the monthly levellings, a sudden jump to the level in the standpipe occurs. Thereafter, when the mini-packer is inflated again, the pressure is slowly approaching the actual pressure in the borehole section. KFMA: Some sections in the borehole are influenced by the pumping performed in the neighbouring borehole KFMB from the middle of March to the middle of May 7. KFMB: Pumping (5 L/min) was performed between mid-march and mid-may 7. SFM5, SFM and SFM58: By the look of the registration, the boreholes seem to be mostly dry during a period from July/August to October/November 7. However, manual levellings performed during this period could not confirm this and therefore no data have been omitted. SFM6: The borehole is reported to be dry from the end of June 7 to the middle of January 8. SFM7: The borehole is reported to be dry at the levelling occasions in August through October 7. 9
