Abstract

Using existing data from the United States Geological Survey coupled with literature, the California Department of Conservation (DOC) embarked on a project to evaluate the magnitude of abandoned mines in California with respect to environmental and human health and safety. The DOC developed a field-sampling regime for two watersheds per bioregion in California. Abandoned mines were sampled for physical and chemical hazards. All mine feature data were coupled with post-processed GPS positions. A relational database was constructed with input forms in Microsoft Access. Spatial analysis with ancillary data was conducted with ArcView.

Introduction

The California Department of Conservation (DOC) conducted an inventory and hazard assessment of abandoned mine sites located in the state, culminating in a report to the Governor and Legislature which details the magnitude and scope of abandoned mine problems in California. Prior to this effort, estimates of the number of abandoned mines varied widely and were based solely on legacy databases. Existing literature and data were collected, input, and spatially analyzed through the implementation of a Geographic Information System (GIS). Data gaps were identified and a field program was implemented to acquire the additional data. Data were collected at selected mine sites, by watershed, in various bioregions throughout the state. Mine features were photographed and precisely located by differentially corrected Global Positioning System (GPS). Field data, in addition to data collected from existing sources, was input into a relational database.

Since the Gold Rush of 1849, tens of thousands of mines have been dug in California. Many of these mines were immediately abandoned when insufficient minerals were found, while others were abandoned later when the economics of the commodity made mining unprofitable. The result is that California’s landscape contains tens of thousands of abandoned mine sites, many of which pose health, public safety, or environmental hazards.

While some information on abandoned mined lands is available from other state, local, or federal agencies, there has not been a statewide clearinghouse for information nor a coordinated statewide effort to address abandoned mine lands in California. The low level of knowledge about the location and impacts of abandoned mines is becoming more evident as the state’s population moves into high-density abandoned mine lands areas such as the Sierran foothills.

Selecting Target Watersheds for Sampling

Due to time constraints (2.75 years), limited financial and staff resources, and the large number of sites, a technique had to be developed to sample a subset of the abandoned mines. Hence, the watersheds became the sampling unit. In order to select "Target Watersheds" to field sample a GIS approach was implemented.

The data sets used to identify our Target Watersheds for sampling are as follows: 1) Jepson Bioregions, 2) Calwater watersheds ver 2.0, and 3) MAS/MILS mineral occurrences. By analyzing all three of these data sets together in a GIS environment 18 watersheds were selected to sample statewide.

The Jepson Bioregions are partitioned into 10 major units: 1) Central Western California, 2) Cascade Range, 3) Mojave Desert, 4) Sonoran Desert, 5) Great Central Valley, 6) Modoc Plateau, 7) Northernwestern California, 8) Sierra Nevada, 9) East of Sierra Nevada, and 10) Southwestern California (Hickman 1993). The Great Central Valley contains mostly sand and Gravel mining operations, which generally pose few health and safety hazards. Therefore, the Great Central Valley Bioregion was removed from the pool of sampled bioregions; thus, making the total number of Bioregions equal to 9 (Figure 1).

Figure 1

The Calwater watersheds data set depicts 987 unique watersheds or hydrologic regions (HRNAME) for the entire state (Appendix 1). The focus was on a field called Hydrologic Area (HANAME) contained within the Calwater dataset. Each Hydrologic Region is composed of many Hydrologic Areas. There are 519 unique Hydrologic Areas for California. Eliminating all the Hydrologic Areas that were located within the Great Central Valley area reduced the total number of unique Hydrologic Areas for sampling to 511. There are watersheds in the Mojave Desert and the Sonoran Desert Bioregions without a Hydrologic Area name. Hence these unnamed watersheds were named via their hydrologic unit name (HUNAME).

The MAS/MILS data set contains mineral occurrences (Appendix 2). A mineral occurrence can be anything from a major mining operation with scores of openings to a small test pit or mining prospect. There are 29,239 mineral occurrences for California (Figure 2). To ensure that sand and gravel operations, which pose few hazards, did not dominate the selected watersheds, mines for which sand and gravel was their primary commodity were removed. Therefore, 2,187 mineral occurrences were removed from the MAS/MILS dataset that depicted sand and gravel as a primary commodity an additional 1,363 mineral occurrences were remove due to a null values in the commodity field; thus making the total number of mineral occurrences equal to 25,689. For a list of commodities and their frequency that are contained in MAS/MILS see Table 1.

First, the watersheds were partitioned by the Jepson’s Bioregions. Next, we intersected the Bioregions Watershed dataset with MAS/MILS. Finally, two watersheds per Bioregion that had the highest frequencies of mineral occurrences were chosen for sampling. Therefore, a total of 18 watersheds were select for sampling: 1) Alameda Creek, 2) Hurlong, 3) Lake Shasta Drainage, 4) Lower Owens, 5) Middle Klamath River, 6) North Yuba, 7) Pauline, 8) Point Buchon, 9) Scott River, 10) Shasta Valley, 11) Silurian Hills, 12) South Fork American, 13) Susan River, 14) Upper Owens, 15) Ivanpah, 16) Upper Santa Clara, 17) Lucerne Lake, and 18) Southern Mojave (Figure 3). In addition, Clear Creek, Merced River, and Bear River watersheds were added at requests from stakeholders. The watersheds that were field sampled are listed in Figure 4.

Field Sample Sites

After watersheds were selected, mine sites were chosen for sampling. Due to the generalized site location of MAS/MILS data, a project was started that entailed digitizing and attributing the topographic mine symbols for the selected watersheds, and later the entire state. Preliminary fieldwork indicated that the topographic mine symbols were very reliable with respect to mine location (Figure 5).

Figure 5

A process had to be designed for selection of mine sites to be field sampled. The data sets used for this selection process were 1) topographic mine symbols 2) surface geology, and 3) target watershed. First, the watersheds were stratified by surface geology rocktype. Next, 14 topographic mine symbols per each surface geology rocktype were randomly chosen (Figure 6).

Figure 6

Literature Review

After sample sites were chosen, a literature review of historic mining with the study area was conducted. The type of information sought included dates of operation, types of operation, size of operation, and type of ore processing. Often, no information existed about these mine sites; however, other times detailed information, such as a map of the underground mine workings, existed.

Field Data Collection

A field form was developed and used (Appendix 4) as a guide and data recording tool. In the field, GPS positions were collected for feature location. Digital photographs were taken of each mine feature, and water and soil samples were measured for pH, electrical conductivity, and oxidation-reduction potential. Individual mine features were defined by type, size, and condition.

GPS Data

Two models of GPS units made by Trimble Navigation, Sunnyvale California, were used to collect location data. These models were the GeoExplorer II GPS and the Pro XR. The GeoExplorer II was the "work horse" GPS unit for data collection. The GeoExplorer II and the Pro XR have the following default file naming nomenclature. For example, GPS data collected on May 30th at 4:00 PM, would have the following name R053023A. This GPS file name is broken down as follows: 1) the first character "R" is a GPS unit identifier, 2) the next two numbers "05" are the two digit month, 3) the next two numbers are the two digit day "30", 4) the last two numbers "23" are the time on a 24 clock that is offset by Greenwich Mean Time (GMT) or Universal Coordinate Time (UTC) and 5) the last letter "A" is a file identifier for that first file on that hour. So the second file created in the same hour would be named R053023B. We found that these GPSids had to be unique for each mine feature. Therefore, we concatenated the default GPSids with the 4-digit year and a 4-character user id. This user id consists of the user’s initials for their first, middle, and last name coupled with a sequence number. The sequence number at the end of the user id is there to make sure that no two users have the same user id. The final GPSid now was a 16-character value i.e. R053023A2000MFT1. Trimble Navigation, Pathfinder Office version 2.11 was the software used for downloading, postprocessing, and outputting the GPS data. The output GPS file was an ArcView shapefile that contained 5 fields. The first field was the 16 character unique GPSid. The next four fields were two sets of coordinate data. We used geographic, and a modified Albers equal area conic projection with units in meters as our two coordinate systems (Appendix 3).

GIS

The GIS software used was Environmental Systems Research Institute’s (Esri), in Redlands, California, ArcView ver 3.1. A library subscription of GIS data was purchased from the Stephen P. Teale Data Center in Sacramento, California. The GIS data included watershed boundaries, county boundaries, hydrography and Digital Raster Graphics (DRG’s) 7.5 minute topographic. ArcView extensions and scripts were downloaded, from Esri’s website, to facilitate analysis and data production.

Database

Microsoft Access, Office 97 version, service release 2, was used for the database program (Figure 7). Staff constructed the database data entry forms and a series of related tables. All the data collected from field visits including coordinated data, for point data only, were stored in this database. Database rules were enforced such that a mine feature could not be entered

Figure 7

without having coordinated information associated with the mine feature. Therefore, a function was devised, in the database that would allow the user to copy the coordinated data from the shapefile’s associated database file (dbf) to the database. First, the user enters the GISid into the database via the database form. Next, a file browser is spawned and the user is required to browse to a shapefile’s dbf that contains the same GISid that was previously entered into the database. When the correct dbf is located, and a match on the GISid occurs, the coordinated information in the database is populated. Many more functions, fields and relationships are contained in this database (Figure 8).

Figure 8

Results

After 12 months of fieldwork, 780 mine sites, composed of 3,920 mine features were inventoried from 13 watersheds in 9 Bioregions. California contains 2,869 7.5-minute topographic maps. As of May 2000 over 20,000 mine features on over 1000 7.5-minute topographic maps for mine symbols have been digitized. Preliminary work shows that there are on average three times as many mine features on the ground than the 7.5-minute topographic map depicts; and less than 50% of the abandoned mines are included in the legacy databases.

Conclusion

The exact number and location of all of California’s abandoned mines are not known at this time. During the 12 months allocated to field inventory, 780 mine sites were inventoried and 3,920 mine features recorded.

Storing all the data in the relational database, including the coordinate data, made analysis much easier when compared to using ArcView’s "SQL Connect" function. Using the query capabilities of Microsoft Access allowed users to easily select data, produce an output file, and display the data in ArcView.

The MAS/MILS dataset has many locational discrepancies. However, for statewide analysis MAS/MILS is useful. A map of mine densities for the entire state using MAS/MILS is shown in (Figure 9).

Figure 9

Fieldwork indicates that the 7.5-minute topographic mine symbols are a consistently reliable source of mine location information. Therefore, as soon as all the 2,869 7.5-minute topographic maps for the State are digitized for mine symbols, a more reliable statewide mine density map can be created. However, the 7.5-minute topographic mine symbols have limited use. That is, 7.5-minute topographic mine symbols have no ancillary information such as mined commodity, dates of operation, and size of operation. Once ancillary information from MAS/MILS is linked to the mine symbols database, the combined dataset will be very useful to land managers.

A preliminary relationship exists such that there are approximately three mine features on the ground to each mine feature on the topographic map. In order to get an estimate on number of mine features for California we will need to use this three to one relationship. However, the entire State is not digitized for mine symbols. Therefore, this three to one relationship may change as more maps are digitized. As soon as the entire State is digitized, and more mine sites are field visited, a more reliable statistic for the relationship between the map and the field can be calculated.

The relational database of abandoned mines, linked with data collected from other agencies, has been developed and implemented. Additionally, an abandoned mine GIS has been developed and implemented which allows the spatial and statistical analyses necessary to evaluate abandoned mine sites .

1.3 Data Set Description and Status

Description::

1.31 Abstract ::The California Watershed Map (CALWATER version 2.0)

is a set of standardized watershed boundaries meeting standardized

delineation criteria. The hierarchy of watershed designations consists

of four levels of increasing specificity: Hydrologic Region (HR),

Hydrologic Unit (HU), Hydrologic Area (HA) , and Hydrologic Sub-Area (HSA).

The primary purpose of Calwater is the assignment of a single, unique

code to a specific watershed polygon. While there are 987 polygons in

the ARC/INFO coverage, there are actually fewer watershed codes. This

is due to cases of multiple polygons bearing the same watershed code

(Channel Islands, split polygons due to other boundary integration,

e.g. ground water basins). Another confusing factor is that not all

Hydrologic Units are subdivided into Hydrologic Areas, and not all

Hydrologic Areas are subdivided into Hydrologic Sub-Areas. Therefore,

a nominal count of watershed codes in Calwater 2.0 is:

Hydrologic Regions: 10

Hydrologic Units: 182

Hydrologic Areas: 462

Hydrologic Sub-Areas: 622

1.32 Purpose::Mapping, reporting, and statistical analysis of water

resources, water supply, water quality, wildlands, agriculture, soils,

forests, rangelands, fish habitat, wildlife habitat, cross-referencing

state and federal hydrologic unit or watershed codes and names.

Lookup Table of California Hydrologic Region Names and Codes

Codes for Hydrologic Regions and other administrative entities are

cross-referenced in the table below. Ten Hydrologic Regions are

coded numerically by DWR, whereas there are nine Regional Water Quality

Control Boards, with offices in twelve Hydrologic Basin Planning Areas

(HBPA). DWR identifies three HRs in the Central Valley to SWRCB's one

"Region", and SWRCB identifies three RWQCBs in DWR's one South Coast HR.

The two-letter abbreviations SR and SB both refer to the Sacramento

River basin. Other single-letter codes are used in DWR Bulletin 130-85

"Hydrologic Data 1985", and other DWR publications.

Federal Hydrologic Unit Codes (4-digit HUC) Sub-Region codes and names

are also provided. Note that some state designations map to more than

one federal designation. More detailed HUC designations terminate

with the 8-digit HUC, the Cataloging Unit (CU) (USGS 1986, Water Supply

Paper 2294). Detailed, polygon-by-polygon lookup is also possible with

the CU, CU1, CU2, etc codes in the ARC/INFO Polygon Attribute Table above.

IDNUM TO HUC CROSSWALK

The IDNUM to HUC cross-reference was developed with the following rules:

For a given [state] Calwater watershed, overlapping [federal] Hydrologic

Unit Codes (at the 8-digit Cataloging Unit [CU] level) are listed up to

a maximum of 80% of the Calwater watershed OR three CUs, whichever comes

first.

For example:

Where there is only one CU code listed for a given Calwater watershed

code, that CU overlaps at least 80% of the Calwater watershed.

Where there are two CU codes (CU and CU2) listed for a given Calwater

code (only 19 watersheds fit this criterion), the largest CU alone

overlaps less than 80% of the Calwater watershed, but combining CU2

then provides overlap of at least 80% of the Calwater watershed.

Where there are three CU codes (CU, CU2, and CU3) listed for a given

Calwater watershed (only 4 watersheds fit this criterion), the largest

2 CUs together overlap less than 80% of the Calwater watershed; combining

a third CU code produces additional overlap. Complete overlap statistics

are left for calculation by the user.

If a watershed consists of multiple polygons (because it is split by the

groundwater line, the state boundary, or it is comprised of multiple

islands), the total area of the watershed (the sum of all the polygons)

is the value entered in the ACRES item. The individual polygons of a

multi-polygon watershed all have the same watershed code. These cases

primarily designed to be administrative reporting units, and the

boundaries should not be used to define authoritative drainage area above

a given point as a portion of their definition includes non-physical

boundaries, particularly in valley floor and urbanized coastal regions.

Attribute completeness is good. Compatibility with existing state and

federal watershed delineations is good, except where explicitly different

boundary configurations are applied.

INTRODUCTION

The digital data files presented on this disk comprise selected

information from United States Geological Survey (USGS) databases

related to active and inactive mine locations in the state of California

and may be of use to people involved with environmental remediation and

contamination work.

This report can be downloaded via 'anonymous ftp' from the USGS

system named greenwood.cr.usgs.gov (136.177.48.5). The files are located

in the directory /pub/open-file-reports/ofr-96-0004.

The database manager is: Jean L. Ryder

Disclaimers:

The databases, identified as RASS, PLUTO, MRDS, and MILS have been

approved for release and publication by the Director of the USGS.

Although these databases have been subjected to rigorous review and are

substantially complete, the USGS reserves the right to revise the data

pursuant to further analysis and review. Furthermore, it is released on

condition that neither the USGS nor the United States Government may be

held liable for any damages resulting from its authorized or unauthorized use.

Although the program LHA.COM ((c)Yoshizaki,1988-91) was used by the

USGS to archive these files, no warranty, expressed or implied, is made by

the USGS as to the accuracy and operation of the program and related program

material, nor shall the fact of distribution constitute any such warranty,

and no responsibility is assumed by the USGS in connection therewith.

USGS DATABASES

The National Geochemical Database is a collection of geochemical

information maintained by the USGS and consists of five separate databases.

The data retrieved here are from the Rock Analysis Storage System (RASS),

PLUTO, Mineral Resource Data System (MRDS), and Minerals Availability System

(MILS) databases.

MILS

The Minerals Industry Location Systems database provides information on

locations of mines, their operational status, and information about the

minerals at those locations. The California MILS data set contains over

29,000 sites with 64 fields of data. The data on this diskette includes

only the fields consisting of sequence number, name of deposit, deposit type,

current status, location, and point of reference for all 29,096 sites. The

column listed as Sequence Number is composed of ten digits attributed as

follows:

Digits: 1-3 refer to the state code (006 for California)

4-6 refer to the county/province code used by the Department of

Commerce

7-10 designate a unique deposit reference number assigned to

each deposit within the state and county

The Point of Location column lists the point from which the latitude and

longitude were determined. For further information on any of these databases,

contact the database manager listed at the beginning of this report.
