Water
Quality Monitoring
The
identification and quantification of metals in environmental samples
(water, sediments) are often difficult. Currently, many scientists
use atomic absorption spectrophotometry or inductively coupled plasma-mass
spectrometry to detect and quantify metals. Both of these techniques
require destruction of the sample and are limited by the number
of metals that can be analyzed at one time, as well as by sample
size, matrix effects, and limits of detection.
We need
to compile an asset map of water quality monitoring (magnitude,
methods, responsible parties, data issues, etc) for the San Diego-Tijuana
crossborder region. Below are models of such efforts (historical
and current) at different scales.
Office
of Environmental Health Hazard Assessment (OEHHA),
OEHHA is one of six agencies under the umbrella of the California
Environmental Protection Agency (Cal/EPA).
OEHHA’s overall mission is to protect and enhance public health
and the environment by scientific evaluation of risks posed by hazardous
substances. Risk assessment is a scientific process of evaluating
the adverse effects caused by a substance, activity, lifestyle,
or natural phenomenon. OEHHA is responsible for developing and providing
risk managers in state and local government agencies with toxicological
and medical information relevant to decisions involving public health.
State agency users of such information include all boards and departments
within Cal/EPA, as well as the Department of Health Services, the
Department of Food and Agriculture, the Office of Emergency Services,
the Department of Fish and Game, and the Department of Justice.
The Water Toxicology
Unit performs major risk assessment and hazard evaluation activities
relating to chemical contaminants in drinking water. These activities
include developing health advisories, action levels, and public
health goals for chemical substances in drinking water, and providing
toxicological assistance for chemical monitoring activities for
the drinking water supply.
Southern
California Bight Monitoring Program
Inventory of ocean monitoring in the Southern California Bight
ABSTRACT http://www.sccwrp.org/pubs/annrpt/99-00/abst18_ar22.htm
Monitoring of the ocean environment in southern California has been
conducted by a diverse array of public and private organizations
with different motivations, working on a variety of spatial and
temporal scales. To create a basis from which to integrate information
from these diverse programs, we conducted an inventory of ocean
monitoring activities in the Southern California Bight to address
the following questions: (1) How many dollars are being expended
annually on marine monitoring programs? (2) Which organizations
are conducting the most monitoring effort? and (3) How are resources
allocated among the different types of monitoring programs? This
inventory focused on existing programs, or those expected to be
in existence, for at least 10 years and that were active at any
time between 1994 and 1997. For each program identified for inclusion
in this study, information was collected on the number of sites,
sampling intensity, parameters measured, and methods used. Levels
of effort were translated into cost estimates based upon a market
survey of local consulting firms. One hundred and fourteen marine
monitoring programs, conducted by 65 organizations and costing $31
million annually, were identified. Most of the effort (81 programs,
65% of samples, 70% of costs) was expended by ocean dischargers
as part of their compliance with National Pollutant Discharge Elimination
System (NPDES) permit requirements. Federal programs (11 programs,
25% of samples, 10% of total expenditures) expended more than state
or local government programs. More than one-quarter of monitoring
expenditures were conducted to measure concentrations and mass of
effluent inputs to the ocean. The largest effort expended on receiving
water monitoring was for measuring bacteria, followed by sediments,
fish/shellfish, water quality, and intertidal habitats.

Re: Laboratory Intercalibration http://www.sccwrp.org/whatsnew/stormwater_lab_intercal.html
Date: October 17, 2002
Aa unique intercalibration study with the members of the Southern
California Stormwater Monitoring Coalition (SMC). The SMC is comprised
of the 11 lead regulatory and regulated agencies for municipal stormwater
NPDES permits throughout southern California. The SMC is interested
in increasing comparability among their monitoring programs in order
to make regional assessments of stormwater quality. Similarly, members
of the SMC will be coordinating their efforts with the Regional
Monitoring Project for the Southern California Bight, commonly referred
to as "Bight '03". Therefore, the SMC will be utilizing
the Southern California Coastal Water Research Project (SCCWRP)
to lead the intercalibration study by coordinating round-robin testing
for a variety of analytes including suspended solids, nutrients,
trace metals, polynuclear aromatic hydrocarbons, and organophosphorous
pesticides. The ultimate goal of the study will be to develop performance-based
quality assurance and quality control criteria for ongoing stormwater
testing throughout the region. Laboratories that wish to analyze
stormwater samples on behalf of SMC member agencies in the future,
or participate in Bight '03, will need to verify that they can meet
the performance-based criteria developed as part of this intercalibration
study.
The study will necessitate your cooperation in three main areas.
First, we will request your assistance in refining the study workplan.
Second, we will request your lab to analyze the round-robin samples
distributed to each facility. This may require at least two or more
iterations, depending on the success of each laboratory. Third,
we will request your assistance in developing the performance-based
objectives that will be described in our laboratory manual for stormwater
testing. We have enclosed a project Scope of Work for your reference
on the details of this study. We expect to begin this study by December
2002 and complete it within 12 months.
Please contact Ken Schiff at 714.372.9202 by November 15th so we
can add your name to the list of participating laboratories.

Tijuana
River Reserve, California http://nerrs.noaa.gov/TijuanaRiver/
Location: The reserve is located near Imperial Beach, in San Diego
County, on the Mexican border.Total Acreage: 2,500 Lead State Agency:
California Department of Parks and Recreation
The Tijuana River Reserve is located in a highly urbanized environment.
The reserve encompasses beach, dune, mudflat, saltmarsh, riparian,
coastal sage and upland habitats surrounded by the growing cities
of Tijuana, Imperial Beach and San Diego. Three quarters of the
reserve’s watershed is in Mexico and the management, education
and research issues involve an international perspective. Critical
issues confronted by the reserve include habitat restoration, endangered
species management, management of the wastewater from Mexico, sediment
management, and the integration of recreation and habitat conservation
and restoration.
Agency
for Toxic Substances and Disease Registry (ATSDR)
Copied from meeting minutes posted at: http://www-apps.niehs.nih.gov/sbrp/rfa/atsdr.html
SBRP
staff have sought to maintain productive relations with ATSDR. Dr.
Robert Spengler, Associate Administrator for Science, has served
as the primary liaison with ATSDR. Dr. Chris DeRosa has served on
different SBRP committees and has graciously agreed to serve as
a member of the EAG. Collaborative efforts have resulted in the
joint publication of a special issue of the International Journal
of Hygiene and Environmental Health that highlights the Superfund-related
research being conducted by USEPA, ATSDR, and SBRP. The SBRP has
also been involved in the NIEHS - ASTDR collaborative efforts to
promote an integrated research agenda and the most effective use
of research results in the field. On February 12, 2002, Drs. Olden
and Falk convened a meeting of both agencies' senior scientists
and managers to identify a few areas for the two agencies to focus
particular efforts of coordination. The two agencies followed up
on the SBRP - ATSDR specific collaboration efforts in a meeting
in early January 2003. At this meeting SBRP staff met with Dr. Henry
Falk, Assistant Administrator ATSDR, and many ATSDR Division Directors.
Details of the meeting are specified in the meeting report presented
below:
ATSDR
Meeting Report
The
NIEHS SBRP staff met with senior ATSDR management on January 7th
to discuss how the SBRP program presently supports the ATSDR mission,
how it may be able to do more in the future, and what research needs
are most critical to ATSDR.
Bill
Suk, Beth Anderson, Claudia Thompson, and Larry Reed from SBRP and
Jayne Michaud from USEPA Superfund met with Henry Falk and Peter
McCumiskey, ATSDR Division Directors and other senior managers (including
Juan Reyes, Chris DeRosa, Libby Howze, and David Williamson).
The
major observations made by Dr. Falk were:
Since
both ATSDR and NIEHS report sequentially to the same VA-HUD appropriation
committee, it is important to continue to emphasize the dialogue
and collaboration between the two agencies.
ATSDR needs to be using the NIEHS science in discharging its mission.
ATSDR is a service agency, basically, but it is a difficult
task since the science is so imperfect. Therefore, sound science
can only support their efforts.
The response to the WTC disaster has shown that both agencies must
be positioned to integrate their disaster response capabilities
to be prepared for any future major disasters.
Informatics is an area of continued interest; opportunities for
coordination should be pursued.
NIEHS' toxicogenomics program has important implications
to ATSDR's health assessments and continued dialogue between the
two agencies is important.
CDC's emphasis is presently on assessing potential biological agents,
but they are also working from a master list of 501 possible chemicals
of concern for a terrorist action. Many of those chemicals have
incomplete toxicity data. This is of potential interest to ATSDR
and NIEHS, and efforts need to be coordinated.
The
larger meeting with ATSDR division directors was chaired by Peter
McCumiskey. Some of the major observations included:
Both
Agencies recognize the need to demonstrate not only the collaboration
being undertaken, but also the real world benefits of that collaboration.
Community outreach is a very good area to focus on collaboration.
In the area of children's health, the ATSDR Pediatric Environmental
Health Services Units (PEHSUs) and NIEHS' Children's Health Centers
have been collaborating very well. This demonstrates an area where
non-Superfund NIEHS resources are being leveraged to further help
the USEPA Superfund field program.
Informatics was cited as a field still early in the developmental
stages. A joint committee was looking to ensure that there was coordination
between the agencies, especially in the development of new databases.
NIEHS' microarray data may be a very appropriate early application
of a coordinated informatics approach.
SBRP noted that NIH has a GPRA goal of an integrated database system
by 2012, so we should make sure our collaboration is integrated
with those broader efforts.
The Gene SNP's data base may be another good pilot informatics collaboration
effort.
The importance of the human genome research results need to be translated
to the general public and to the field of risk assessment.
The SBRP GIS research programs at University of California
- San Diego and Boston University could serve as useful tools in
the development of the informatics collaboration between the agencies.
ATSDR would like to learn more about the University of California
- San Diego GIS effort.
Coordinated research efforts that the two agencies have initiated
(e.g., thyroid hormone research, portable analytical devices, and
biomarkers) are continuing.
The importance of developing real time field analytical
equipment was emphasized. Communities want such real time
data if new technologies are going to be used to remediate a site.
Such research also has counter-terrorism applications. Local communities
are very interested in monitoring technologies that they can use
(e.g., radon testing kits).
WATER
MONITORING OUTREACH PROGRAM
http://www-biology.ucsd.edu/labs/schroeder/watermonitor.html
In the fall of 2001 the Schroeder laboratory at UCSD begun a collaboration
with the San Diego Baykeeper organization ( www.sdbaykeeper.org
) to assist the grassroots organization in monitoring water quality
at sites throughout San Diego county. The San Diego Baykeeper was
established to enforce the provisions of the federal Clean Water
Act of 1972. The organization measures levels of bacteria and toxic
metal contamination, and when contamination is found reports these
to governmental organizations (such as the EPA and the cities of
San Diego and Encinitas) responsible for the pollution. As some
areas of the San Diego Bay are polluted, the work of the San Diego
Baykeeper is instrumental in preserving the water quality in San
Diego. A graduate student, David Lee, and a high school student,
Josephine Aguilar, of the Schroeder lab have joined Baykeeper in
collecting water samples from Paleta and Chollas Creeks, both designated
toxic hot spots by the State Water Quality Board, and process these
samples along with others collected from around the county. The
water samples are being measured on the ICP-AES machine in Jeff
Harper’s laboratory at The Scripps Research Institute, and
further analyzed in the Schroeder laboratory to determine the levels
of dissolved metals such as arsenic and lead. The data we are generating
has been presented by Baykeeper to the City of San Diego.

WATER
QUALITY MONITORING AND ASSESSMENT
Adequate
and accurate monitoring and assessment is the cornerstone to
preserving, enhancing, and restoring water quality. The information
gathered
from these monitoring activities is critical for: determining the
effects of point
and nonpoint source pollution; protection of drinking water supplies;
conducting
federal Clean Water Act assessments; determining trends in water
and habitat
quality; and developing water quality standards and then determining
if they are
strategic projects.
The
1999 Compliance Assurance and Enforcement Initiative established
the goal
of achieving measurable and continuing increases in compliance rates
and
identified a wide variety of challenges and proposed solutions.
Improved data
management is the cornerstone for improved compliance assurance
and
enforcement. Regulators, policy makers, and the public need better
access to
being met. A number of recent legislative actions have identified
the need for
improved water quality monitoring in California. The 1999-00 Budget
Act
required us to provide a plan for comprehensive surface water and
groundwater
monitoring. In November 2000, in response to Assembly Bill (AB)
982 (1999
legislative session), the State Board submitted to the Legislature
a comprehensive
plan for the Surface Water Ambient Monitoring Program (SWAMP) and
Groundwater Ambient Monitoring and Assessment (GAMA). The State
and
Regional Boards are now implementing these programs to the extent
funding is
available. (p. 10)
Our
last goal focuses on our ability to measure results. It is critical
that we have
the appropriate systems in place allowing us to assess and report
on our progress
toward improving and restoring California’s water resources.
At this time, we do
not have enough monitoring resources to effectively evaluate the
state’s water
quality. We will work with stakeholders to identify and implement
additional
monitoring resources. We will use measures to determine the effectiveness
of our
program activities and make modifications to improve that effectiveness.
We will
also work closely with stakeholders to develop and implement the
most effective
measurement and reporting tools so that we may communicate a consistent
message regarding California’s water quality. Included in
this effort is our
participation in the Cal/EPA EPIC Project which is developing environmental
GOAL
#6: WATER QUALITY IS COMPREHENSIVELY MEASURED TO EVALUATE
PROTECTION AND RESTORATION EFFORTS
"How will we accomplish our goal?"
We will achieve this goal by pursuing the following measurable objectives:
*Increase the amount of useable quantitative data and information
regarding water quality
*Translate quantitative data into useful information regarding the
status of
water quality
*Coordinate the collection and reporting of water quality information
among
programs, agencies and stakeholders
"What
actions will we take to achieve our objectives?"
* Develop the systems and processes to measure and demonstrate quantitative
improvements in and maintenance of water quality
* Improve intra-agency, inter-agency and stakeholder coordination
of
programs and data sharing
* Surface Water Ambient Monitoring Project: Coordinate surface water
monitoring efforts so that they are comprehensive, non-duplicative,
and
appropriately funded. Create an ambient monitoring program that
addresses all hydrologic units of the state using: consistent and
objective
monitoring, sampling, and analytical methods; consistent data quality
assurance protocols; and centralized data management. Document
ambient water quality conditions in potentially clean and polluted
areas.
The scale for these assessments ranges from site-specific to statewide.
Identify specific water quality problems preventing the State and
Regional
Boards and the public from realizing the beneficial uses of water
in targeted
watersheds.
* Groundwater Ambient Monitoring and Assessment Project: Facilitate
coordination, communication, and data sharing among various
groundwater programs and agencies. Compile groundwater information
and data widely so that it can be used by multiple programs and
agencies,
and is accessible to all stakeholders. Assess groundwater susceptibility.
* System for Water Information Management (SWIM 2) Project: Provide
automated tools and standardized business processes to improve the
State
and Regional Boards’ ability to enhance and preserve the quality
of the
state’s waters. This will be done by building a comprehensive,
integrated,
appropriately accessible system with consistent, reliable data.
The system
will expand existing system capabilities to include licensing and
monitoring
programs. It will automate manual processes, allowing electronic
submissions of reports and importing of relevant data. It will make
data
Internet-accessible. The system will provide tools for integrated
watershed
assessment and management. The system will also include the
functionality currently included in the Geographic Environmental
Information Management System – GEIMS (also known as GeoTracker).

Biomarker-Based
Analysis for Contaminants in Sediments/Soil: Review of Cell-Based
Assays and cDNA Arrays
PURPOSE:
This technical note reviews the existing technology for cell-based
biomarker assays andcDNAarrays and explores their potential as rapid,
sensitive, and low-cost tools for sediment/soil toxicity screening.
The
P450RGS assay illustrates the potential savings and benefits offered
by cell-based assays. Although gas chromatography-mass spectroscopy
(GC-MS) is the definitive method for identifying and determining
the precise amount of dioxin and dioxin-like compounds present in
an environmental sample, the method is expensive (~$1,200 -$2,000
per sample). P450RGS is far less expensive at about $200 per sample,
and its use can result in major cost savings when used to screen
multiple
sediment cores to determine which samples should be confirmed by
GC-MS.
EPA's
Field Analytic Technologies Encyclopedia (FATE) web site.
http://fate.clu-in.org/
This
online encyclopedia is intended to provide information about technologies
that can be used in the field to characterize contaminated media,
monitor the progress of remedial efforts, and in some cases, for
confirmation sampling and analysis for site close out.
Technological
advances over the past decade have created a whole new set of tools
to improve site cleanup and long-term monitoring. Computerization,
microfabrication, and biotechnology permit the development of analytical
equipment that has capabilities that blur the distinction between
"screening methods" and "definitive methods."
In the next decade, technological advances are likely to alter that
landscape even more dramatically.
The
various technologies presented on this web site are grouped into
the following categories:
•
Analytics
• Direct-Push Technologies
• Explosives
• Geophysics
• Sampling
• Sampling Design
Freshwater
and Marine Toxicity Tests
http://www.oehha.ca.gov/ecotox/pdf/marinetox.pdf
Document
provide an overview of the various standardized aquatic toxicity
test protocols available for hazard assessment. Environmental managers
responsible for assessing the ecological integrity of aquatic resources
in California rely on a number of assessment tools including chemical
analysis of water, sediment, and tissue; biological assessments;
and toxicity tests. Toxicity tests are an important component for
assessing the impact of chemicals on aquatic ecosystems because
they indicate toxic effects of complex chemical mixtures. In aquatic
toxicity tests, groups of selected organisms are exposed to test
materials (water or sediment samples) under defined conditions to
determine potential adverse effects. A number of standardized toxicity
test protocols have been developed for determining toxicity of chemicals
to aquatic species. Detailed guidance manuals for marine and freshwater
toxicity tests are available from the United States Environmental
Protection Agency (U.S. EPA) and other entities such as the American
Society for Testing and Materials (ASTM). These protocols provide
guidance on application of toxicity tests for
assessing toxicity of single chemicals, complex effluents, and ambient
samples of water or sediment.
