***Water Quality Indicator Tools***

**[Purpose and Scope]{.underline}**

This technical note provides information on *water quality indicator
tools* for use by Natural Resources Conservation Service Field Office
Personnel and others. These tools are organized and designed to be used
in conjunction with the Field Office Technical Guide (FOTG), Section
III, Quality Criteria. These tools are to be used to indicate and
document whether conservation management systems (CMS) meet the water
quality criteria at the resource management system (RMS) level (NPPH,
Amendment 2, April 1998). A CMS combines individual conservation
practices into a system that, when installed, prevents the degradation
and permits sustained use of our natural resources (soil, water, air,
plants and animals).

Indicators provide a measure for, or can describe a current, past, or
future resource condition. Indicators only estimate resource conditions
so their use must be combined with common sense and professional
judgment. The tools presented also provide general background into the
pollution process for different water quality parameters. This
information can help educate and remind conservation planners of
resource considerations related to water quality. Indicator tools can be
used to determine water quality problems, set benchmark conditions,
guide inventories, and evaluate and document water quality in the
future. The planner can use the tools with their clients to help them
understand pollution concepts and how different conservation practices
can reduce or eliminate risks of pollution. Our clients could use most
of the tools to do their own self-assessments.

**[Policies and Regulations]{.underline}**

Clean water is essential to sustain life. Given its importance, the huge
amount of regulations and policies currently in place is not surprising.
Federal legislation addressing water quality dates back to the Rivers
and Harbors Act of 1899 which prohibited disposal of waste materials on
the banks of waterways. The Federal Water Pollution Control Act
amendments of 1972, known as the Clean Water Act (CWA), set an interim
goal popularly referred to as "fishable/swimmable" waters. The specific
CWA objective is to restore and maintain the chemical, physical and
biological integrity of the Nation's waters. Most current water quality
policies and regulations emanate from the Clean Water Act. Appendix A
contains a table summarizing most of the pertinent agency policy, and
federal and state regulations.

NRCS policy (GM 460-401) is simply "to promote the improvement,
protection, restoration, and maintenance of surface and ground water
quality for beneficial uses."

To accomplish this, NRCS will:

-   Provide assistance toward the prevention and correction of water
    quality problems;

-   Ensure activities are in accordance with State defined water quality
    standards, uses, and priorities;

-   Coordinate activities with local, state, federal agencies and others
    to protect water quality and to promote technology development and
    transfer;

-   Create public understanding of water quality concerns;

-   Support data gathering, technology development, and research needed
    to assess water quality resource concerns and the effectiveness of
    best management practices; and

-   Train agency personnel in water quality concepts.

    FOTG, Section III, Quality Criteria for all water quality resource
    concerns can be summarized into "meeting state water quality
    standards."

    **[Principles of Water Quality]{.underline}**

    Water quality is defined by its capability to support beneficial
    uses of water. Beneficial uses include domestic water supply,
    livestock watering, irrigation, aquatic life, water contact
    recreation, navigation, aesthetics, and the like. A water quality
    problem exists when the beneficial or intended use of that waterbody
    is impaired. Chemical, physical, and biological parameters usually
    measure water quality. Common parameters include bacteria, dissolved
    oxygen, nutrients, pH, sedimentation, turbidity, temperature,
    electrical conductivity, and toxics (heavy metals and volatile
    organics). Water quality can also be measured in terms of
    riparian/aquatic habitat condition or from macroinvertebrate, fish,
    or algal populations. Water quantity plays an important role in
    quality by influencing a water bodies assimilative capacity and
    ability to support aquatic life.

    When solving a water quality problem potentially resulting from
    agricultural activities:

(a) the pollutant or stressor causing the problem must be identified,

(b) the cause and effect relationship between the pollutant or stressor
    and the water quality effect must be determined,

(c) the source and pathway of the pollutant must be described, and

(d) appropriate control practices must be selected and applied.

A stressor is any condition caused by management activities. For
example, a reduction of streamside shading can cause elevated water
temperatures that adversely impact aquatic habitat communities.

![](media/image1.png){width="2.975in" height="2.35in"}The pollution
process can be visualized through the pollutant delivery triangle:

-   Availability - Presence and amount of contaminant available.

-   Detachment - Process by which material is mobilized

-   Transport - Pathway by which a pollutant leaves agricultural area to
    receiving waters

    Control of most pollutants can be assessed in terms of the
    capability to impact one or more of these three processes. For
    example, integrated pest management limits the amount of chemical
    pesticide used or reduces its *availability*. Erosion control
    practices control *detachment* of soil particles and subsequent
    sedimentation. A filter strip or buffer intercepts the *transport*
    of sediments to a water body.

    Some water quality concerns like stream temperature, riparian
    habitat, and stream flow cause direct impacts to the stream.
    Understanding of basic riparian habitat management, hydrology, and
    geomorphological principles is necessary to determine appropriate
    solutions to these non-chemical water quality problems.

    **[FOTG Quality Criteria]{.underline}**

    Quality criteria are quantitative or qualitative statements of a
    treatment level required to achieve an RMS for identified resource
    considerations for a particular land area. They are established in
    accordance with local, state, and federal programs and regulations
    in consideration of ecological, social, and economic effects. NRCS
    planning procedures suggest quality criteria be expressed using a
    *target* and an *indicator.* The term target value is used to
    express a desired future condition of a resource as measured by an
    *indicator*. Another way of looking at indicators and target values
    is to think of a yardstick as the indicator and the target as a
    point on that yardstick.

    The following sections describe the FOTG Section III water quality
    resource concerns along with tools that can be used to evaluate
    quality criteria. Included are descriptions for pesticides,
    nutrients, animal wastes, salinity, heavy metals, petroleum
    products, sediment and turbidity, dissolved oxygen, aquatic
    suitability and temperature. NRCS and others have previously
    developed many of the referenced tools. Worksheet versions of new
    tools created for this technical note are included in Appendix B.

    These tools only provide estimates of resource conditions. They
    should always be used with common sense and professional judgment to
    deduce the status of water quality resource concerns. A deductive
    approach, aided by predictive tools, can be used to determine the
    appropriate treatment level for a particular water quality concern.
    Predictive tools alone cannot capture the variance in water quality
    concerns impacted by non point sources. Cumulative impacts and
    individual characteristics of each waterbody and watershed limit the
    precision of predictive tools.

    In areas with sensitive waterbodies and/or vulnerable aquifers, the
    planner should exercise additional care in the tool's application
    and interpretation to minimize risk to the environment and human
    health. Sensitive waters could include those listed as water quality
    limited (303d list or 305b report), harboring endangered or
    threatened species, sole source aquifers, or others suffering from
    effects caused by human impacts.

    Suggested target levels to meet quality criteria are listed for
    indicator tools referenced in this technical note. ***Appendix B
    contains input sheets for computerized tools or hardcopies of
    worksheet tools.*** The planner must still deduce if the suggested
    targets provide the appropriate level of water quality protection
    for site conditions being analyzed.

    **[Pesticides]{.underline}**

    Pesticides-insecticides, herbicides, fungicides, miticides,
    nematicides, etc.-are used extensively to control plant and animal
    pests and enhance production. Storage, mixing, rinsing, and land
    application activities can potentially increase the risk of
    environmental pollution. Exposure to pesticides poses potential
    health risks to humans and the environment. Pesticides may harm the
    environment by eliminating or reducing desirable organisms and
    upsetting complicated ecosystem relationships. Toxic effects of
    pesticides are referred to as acute (immediate lethal or sublethal
    effects) or chronic (cumulative effects from long term exposure).

    Many physical, chemical and biological parameters affect a
    pesticides potential environmental hazard. Three pesticide
    properties are often used to describe their potential to contaminate
    water:

```{=html}
<!-- -->
```
-   Solubility

-   Half-life

-   Adsorption

    Solubility is the measure of a pesticide's ability to dissolve in
    water. Pesticides with higher solubility have a greater potential to
    be lost in runoff or in migration to ground water.

    The persistence of a pesticide is measured as the time for one-half
    of the applied material to disappear (half-life). In some cases, a
    pesticide may degrade into a different compound or metabolite with
    more persistence and/or toxicity than the original pesticide.

    A pesticide's chemical properties along with soil characteristics
    (moisture, pH, organic matter, clay content, and texture) determine
    the extent to which a pesticide is sorbed to soil particles. The
    sorption coefficient (K~oc~) measures the quantity of pesticide
    adsorbed by the soil. For example, dicamba salt has a low sorption
    coefficient (K~oc~ of 2) and benomyl has a high coefficient (K~oc~
    of 1900). Consequently, dicamba salt is highly mobile compared to
    benomyl which will be tightly bound to soil particles.

    *Availability* of pesticides is best controlled through proper pest
    management that minimizes the use of specific pesticides through
    integrated pest management techniques. Integrated pest management
    (IPM) combines biological, cultural and other alternatives to
    chemical control with the judicious use of pesticides. IPM includes
    activities like:

```{=html}
<!-- -->
```
-   scouting

```{=html}
<!-- -->
```
-   forecasting pest outbreaks

```{=html}
<!-- -->
```
-   introducing beneficial insects

```{=html}
<!-- -->
```
-   using pest resistant crops, crop rotations, cultivation, and
    fertility management

-   altering pesticide selection and application (timing, rate and form)

    Pesticide *detachment* and *transport* within the environment is
    governed by several factors:

```{=html}
<!-- -->
```
-   Pesticide's properties (solubility, half-life, and adsorption).

-   Soil characteristics (runoff, leaching and erosion potential)

-   Precipitation, temperature and other climatic conditions

Evaluating and understanding these properties should help the planner
devise pest management alternatives that will minimize potential
negative impacts. Rate, form, method, and timing of a pesticide
application all become important components. Supporting conservation
practices that reduce erosion, runoff, and leaching reduce detachment of
pesticides while practices such as filter strips, buffers, sediment
ponds, and grassed waterways can be used to interrupt the transport of
pesticides.

Several tools exist that can be used to indicate whether pesticide use
meets FOTG Quality Criteria for field application to crops and
pastureland, and for pesticide storage, handling, and disposal. The
following table lists the tools, applicability to surface and
groundwater concerns, RMS target level, and reference. The RMS target
level simply indicates a low risk situation for a pesticide's use. A
moderate or high risk rating does not necessarily mean a pesticide
cannot be used, nor does a low or very low rating mean indiscriminate
application is appropriate. Observation of setting, climate, operator's
skill and other factors combined with the planner's own professional
judgement must be used to deduce if a particular pesticide represents a
water quality hazard and what mitigating practices might be needed.

**Note:** *The planned conservation management system must include
practices that overcome the specific site or chemical limitations and/or
utilize integrated pest management to limit pesticide use.*

The ***Windows Pesticide Screening Tool (WINPST)*** compares soil
properties with pesticide properties to determine loss potentials.
***WINPST*** follows the soil pesticide interaction screening procedure
(SPISP) originally developed by Don Goss, NRCS Soil Scientist in the
early 1990's. ***WINPST*** adds conservation management practices to
SPISP to evaluate how mitigating measures can modify pesticide loss
potentials. In addition, the model adds ratings on the pesticide's
toxicity to humans and fish. ***WINPST*** can be used to evaluate both
benchmark conditions and RMS alternatives. The ***Water Quality
Indicators Guide (Field sheet 4B)*** evaluates a cropland field's
potential for surface loss of a generic pesticide.

For example, assume a client in Roosevelt County grows alfalfa. He/she
applies Treflan 5G (trifluralin) to control broadleaf weeds in the
spring. The major soil in the field is a Clovis FSL (85). He/she applies
no practices to control erosion or runoff. The farm is adjacent to
Alamosa Creek.

The dealer provides recommendations to the client for 4 pesticides which
could be used: Treflan (trifluralin), Sinbar (terbacil), Eptam (EPTC),
and 2,4-DB. The planner scans all four pesticides with the ***WINPST***
to determine if some pesticides represent less environmental risks than
others. The results are shown in the following table.

Clovis FSL soils, as managed, have a high leaching potential,
intermediate surface loss potential and intermediate adsorbed loss
potential. The soil/pesticide interaction ratings ***(WINPST)*** for
treflan, the producer selected pesticide, are high for leaching, low for
surface loss, and intermediate for adsorbed loss (attached to eroded
soils particles). The human and fish toxicity hazards are high for
leaching and intermediate for surface runoff.

Hazard ratings of "Low" or "Very Low" require no further action if the
pesticides are used according to the label and meet quality criteria for
Resource Management Systems. IPM methodologies, where available, shall
be incorporated into planning alternatives, even when soil-pesticide
interaction hazard ratings are "Low" or "Very Low". Hazard ratings of
"Intermediate" or "High" require conservation treatment techniques to
meet quality criteria for an RMS. "High" ratings warrant more extensive
treatment than "Intermediate" ratings. Conservation treatment techniques
may not be effective for "Extra High" hazard ratings. In these cases, an
effective, economically acceptable pesticide with a lower environmental
risk or an alternate method of pest control shall be considered. In the
case of extra high leaching hazard for fish and humans and located in a
sensitive area, conservation treatment techniques are considered to not
be effective and the planner shall suggest selection of another
alternative.

With treflan, the target RMS levels are exceeded for leaching (ground
water) and surface runoff hazards. Treatment alternatives that add
erosion/runoff control such as a setback and riparian herbaceous cover
would reduce the high and intermediate soil/pesticide interaction
ratings. However, the rating for leaching will be difficult to reduce to
the RMS level with just irrigation water management. The planner would
want to suggest that another effective, economically acceptable
pesticide with a lower environmental risk be selected or that another
alternative using various combinations of cultural and mechanical weed
control be selected. The planner must evaluate each alternative to
ensure that each is sufficient to meet quality criteria. Other factors
such as the distance to a receiving water body and the probability of
runoff from a rainfall event should also be considered when deciding
whether quality criteria will be met.

The ***Pesticide Storage, Handling, and Disposal Worksheet* provides**
an assessment tool that can be used to judge the pesticide risks
associated with their storage, handling and disposal. The worksheet
provides a basis for indicating if quality criteria is being met and
helps identify practices that need to be considered. The worksheet was
derived from New Mexico Farm\*A\*Syst worksheets on pesticide storage
and handling.

Assume the same client stores over 55 gallons of mostly liquid
pesticides. Most have a high leaching or surface loss potential. They
are stored in their original, good condition containers inside a shed
with a concrete floor with curbed foundation. Mixing occurs outside on a
pervious soil surface located near (less than 50 feet from) an ephemeral
ditch. Pesticide materials are hand poured into sprayer. All handling
and cleanup occurs at the same site, rinsate dumped on ground. Used
containers have been stacked, outside the shed for a number of years.

Based on this information using the ***Pesticide Storage, Handling, and
Disposal Worksheet*** this client has a moderate to high risk of
creating a surface or a groundwater problem. If the RMS alternative
includes: practices for mixing and handling pesticides on an impervious
surface with curbs and sump; and recommends use of more dry product
formulations, collecting rinsate and applying back on targeted fields,
properly recycling used containers, and installing an anti-backflow
device, the rating would improve to low-moderate risk meeting the target
RMS level.

#### Nutrients, Organics and Pathogens

Nutrients are defined as any organic or inorganic substances that
promote plant or animal growth. Organics include animal wastes and other
biosolids. Animal wastes can contribute nutrients, organic matter, and
pathogens to receiving waters. Nitrogen and phosphorus are the two major
nutrients from agriculture that can degrade water quality. When these
nutrients are introduced into a stream, lake or estuary at high rates,
aquatic plant productivity may be increased dramatically by a process
referred to as eutrophication. Eutrophication has many negative side
effects on aquatic ecosystems. Increased growth of algae and aquatic
weeds can degrade water quality, reduce dissolved oxygen levels, cause
wide pH fluctuations and interfere with use of the water for fisheries,
recreation, industry, agriculture, and drinking. Toxins produced by
explosive growth of some algae and dinoflagellates can pose serious
health threats to humans, wildlife, and livestock. High levels of
nitrate (\>10 ppm nitrate nitrogen) in drinking water reduces the oxygen
carrying capacity of blood which is potentially dangerous to infants
(blue baby syndrome). Organic matter includes a family of compounds
containing carbon. Excessive concentration of organic matter in surface
water results in increased turbidity and oxygen consumption. In ground
water, organics have been found to cause foul odors and tastes.
Pathogens associated with animal wastes can transmit diseases to humans
and livestock.

Nitrogen is naturally present in soils but is often added to increase
crop production. Only nitrate and ammonium ions are taken up by plants.
Because of the complexities of the nitrogen cycle, it's difficult under
typical field conditions to account for all sources and sinks of
nitrogen.

-   Mineralization: Conversion of organic N to ammonium NH~4~^+^

-   Nitrification: Conversion of ammonium NH~4~^+^ to nitrate NO~3~ ^-^
    through microbial process

-   Denitrification: Conversion of nitrate NO~3~^-^ to atmospheric
    nitrogen N~2~ or N~2~O

-   Volatilization: Ammonia NH~3~ to gas loss

-   Immobilization: Uptake of nitrogen by soil microbes

-   Plant Consumption: Uptake NO~3~^-^ and NH~4~^+^ by plants

-   Leaching and runoff: Negatively charged nitrate moves readily with
    water through the soil, below the root zone or running off a field.

-   Erosion: Positively charged ammonium is held to soil particles and
    therefore is more apt to be lost by erosion.

Commercial fertilizers applied in the form of nitrate and ammonium are
readily available to plants but also are susceptible to loss through
leaching, runoff, and erosion. Adding nitrification inhibitors to
ammonium fertilizers slows down the microbial conversion to nitrate N
which helps reduce N loss in surface runoff and leaching. Urea based
fertilizers and animal wastes convert to ammonia, which is subject to
volatilization losses unless incorporated into the soil (changed to
NH~4~^+^ and adsorbed to soil particles). A portion of animal wastes
contains more stable organic N that must slowly go through
mineralization and nitrification before it's available to plants.
Consequently, not all of the N from animal wastes is converted to plant
available forms in the year the manure is applied. Ammonia, if delivered
directly to water bodies, can be very toxic to fish and aquatic
invertebrates and can deplete the water of dissolved oxygen. Gas losses
from denitrification and volatilization contribute to air quality and
greenhouse gas concerns.

Phosphorus (P) is one of the key essential elements for plant growth.
Fertilization of crops comprises the largest proportion of P used in
agriculture. Phosphorus has important functions in plant growth, the
primary one being the storage and transfer of energy through the plant.
Excess phosphorus in water bodies promotes eutrophication.

Only a small percentage of phosphorus in the environment is readily
available for use by living organisms. The orthophosphate (H~2~PO~4~^-^,
HPO~4~^-2^, and PO~4~^-3^) ion (or dissolved P) is the form that is
readily soluble and available for use by biological systems. The
majority of inorganic phosphorus in the environment is adsorbed to the
iron, aluminum, and manganese oxides or to clay particles. Organic
phosphorus is mostly held in soil organic matter. The portion of the
phosphorus held by the soil that is subject to change is referred to as
the labile fraction. The equilibrium between the labile and dissolved P
depends on the biological and chemical characteristics of the soil or
water body. Phosphorus is very insoluble in both acidic and alkaline
soils, and most soluble in pH neutral soils (6.0 to 7.5). Most P is
moved into runoff from agricultural fields by dissolution and erosion.
Although generally considered a less important mechanism than surface
runoff, P leaching followed by shallow lateral subsurface flow can
contribute dissolved P to surface waters, especially when high water
tables exist. Soils with large macro pores would also facilitate
dissolved P loss. This mechanism becomes more important in soils with a
large accumulation of P that saturate surface soil sorption capacity
leading to downward and lateral movement of P. Phosphorus applications
(commercial fertilizers or animal wastes) beyond this threshold increase
the opportunity for loss of dissolved P. Animal wastes have
proportionally more phosphorus than nitrogen compared to plant
requirements, resulting in the buildup of excess phosphorus if wastes
are applied at agronomic rates for nitrogen.

*Availability* of nutrients is best controlled through proper nutrient
management that budgets nutrient application according to residual soil
nutrient levels and crop requirements. Soil tests, testing nutrient
content of manure and basing nutrient requirements on reasonable yield
estimates are needed for accurate nutrient budgets.

Nutrient *detachment* and *transport* within the environment is governed
by several factors:

-   Nutrient form, method of application, and timing.

-   Soil characteristics (runoff, leaching and erosion potential; clay
    content, pH, etc.)

-   Precipitation, temperature and other climatic conditions

Nutrient detachment controls are primarily management practices to
prevent surface flow or water infiltrating into the soil from coming in
contact with nutrients. Timely incorporation of manure, sludge, or
fertilizers beneath soil surface can reduce excess nutrients in runoff.
If the nutrients cannot be incorporated, they should be spread on fields
with close growing crops or crop residue to control runoff and erosion.
Prevention of nutrient contamination of groundwater can also be
accomplished by use of nutrient forms that are not easily detached such
as low solubility or slow release fertilizers. Nutrient applications can
be applied in split applications to be available in the amounts and in
the time frames crops need them. Supporting practices such as filter
strips, buffers, sediment ponds, and grassed waterways can be used to
interrupt the transport of nutrients. Cover crops can be used to utilize
excess soil nutrients. Deep-rooted crops within a rotation can recycle
nutrients that have moved below the rooting zone of more shallow rooted
crops.

Animal wastes are potential sources of approximately 150 diseases.
Numerous factors influence the nature and amount of disease producing
organisms that reach surface or groundwater. Some of these are climate,
soil types, depths to water table, infiltration rates, topography,
animal types, and presence of disease-causing organisms. When livestock
wastes are applied on dry, sunny days harmful bacteria die off quite
rapidly. Manure applied on cool rainy days to water saturated soils can
yield high concentrations of bacteria and viruses in runoff. Pathogens
are carried with surface runoff or subsurface flows to receiving waters.
For quality criteria purposes, it generally can be assumed that if
animal manures are properly managed as nutrients that pathogens will
also be controlled.

Several tools exist that can be used as indicators of whether nutrient
use meets the nutrient RMS target level. The following table lists the
tools, applicability to surface and groundwater concerns, RMS target
level, and reference.

The ***Phosphorus Index*** was originally issued as a NRCS South Central
Technical Center Technical Note in the early 1990's. An empirical rating
is developed for the potential loss of phosphorus from an agricultural
field while considering various phosphorus source and transport factors.
New Mexico NRCS issued Agronomy Technical No. 57 of the phosphorus
index. The ratings indicate if quality criteria for phosphorus are being
met and can help to identify conservation practices needed for
mitigating effects.

The ***Nitrogen Index*** is patterned after the Phosphorus Index
incorporating management factors from the discontinued FOCS water
quality tools (nitrogen screening tool) (New Mexico's Nitrogen Index was
adapted from the Oregon Nitrogen Index). Both indices can be used to
analyze benchmark conditions and compare results with RMS alternatives.
The ratings indicate if quality criteria for phosphorus and nitrogen are
being met and can help to identify conservation practices needed for
mitigating effects.

The ***Water Quality Indicators Guide Field Sheets*** can also be used
to indicate the potential for nutrient loss. The ***Water Quality
Indicators Guide (Field Sheets 2B~1~, 2B~2~, and 3B)*** provide
indications of whether the management of animal wastes or commercial
fertilizers have a potential to contaminate surface waters.

The ***Nutrient Storage and Handling Worksheet*** provides an assessment
tool that can be used to judge the nutrient risk associated with the
storage and handling of commercial fertilizers. Additional worksheets on
***Livestock Waste Storage* and *Livestock Yard Management*** can be
used to judge whether nutrients, organics, and pathogens associated with
animal wastes are being properly handled. The worksheets provide a basis
for indicating if quality criteria is being met and helps identify
practices that need to be considered.

## Salinity

The natural weathering process of soil and geologic material produces
salts. They are present in varying degrees in all soils and in both
ground and surface waters. High salt concentrations are more likely to
occur in semiarid and arid regions where evaporation exceeds
precipitation. The salt content of water is usually expressed as the
total dissolved salt (TDS) concentration (mg/l) or as electrical
conductivity with units of decisiemens/meter (dS/M).

Salt loading associated with agriculture occurs through irrigation that
percolates through a salt laden soil profile or geologic layer on its
way back to a stream, or when irrigation return flows concentrate salts
through evapotranspiration. Loading of salt can also occur with the
application of animal and other organic wastes, fertilizers and some
pesticides.

Salinity can be problematic for crop and forage production if
concentration in the soil or in applied irrigation water exceed salt
tolerance levels for the crops being grown. Salt accumulation breaks
down soil structure and reduces infiltration as well as becoming toxic
to crops. High salt concentrations in streams and lakes can also harm
the freshwater flora and fauna. Dissolved salts can create "osmotic
stress" that reduces water available to plants. Total dissolved salt
(TDS) concentrations can be tolerated by humans up to 2000 mg/l.
Livestock can tolerate somewhat higher levels. However, state standards
for drinking water limit TDS to 500 mg/l or approximately 0.7 dS/M.
Salts can also cause excessive corrosion of equipment and is especially
problematic with some irrigation system hardware.

Salt ions are made up of anions of chloride, nitrate, sulfate, carbonate
and bicarbonate combined with cations of sodium, potassium, magnesium,
and calcium. Salts are highly soluble and readily move with runoff or
through leaching. Salinity control, again usually of greatest concern in
arid regions, can be achieved through proper irrigation water management
and/or animal waste management. Salinity control is complicated because
not enough leaching can create salt accumulations in the soil, which
affects crops, whereas too much leaching may mean downstream problems or
increasing salinity in the aquifer.

Electrical conductivity (EC) can be used to indicate salt concentration,
however the potential concentration of other ions in solution must be
considered. Electrical conductivity is measured in millimhos per
centimeter or deciSiemens per meter at a temperature of 25 degrees
Centigrade. It measures how easy it is to pass an electric current
through water. An approximate relationship between EC and TDS is that
650 ppm total dissolved salt is equal to 1.0 deciSiemens per meter
electrical conductivity.

Electrical conductivity can be used as an indicator of excessive
salinity or total dissolved salts. For drinking water electrical
conductivity should be less than 0.7 dS/M. Taste can be used as an
indicator in lieu of testing for total dissolved salts for drinking
water. For most crops and freshwater aquatic plants electrical
conductivity should be less than 3.0 dS/M to meet quality criteria. Salt
tolerances for specific crops can be found in the New Mexico Irrigation
Guide. The **NM Irrigated Leaching Index and Salt Management Tool**
provides an indicator of excessive salinity. The RMS target level would
be an LI\<0.75. The **Water Quality Indicators Guide -- Field Sheets 5A
and 5B~1~** may be useful in flood or furrow irrigated areas. The RMS
target level for salinity using the WQIG would a rating of good or
excellent.

## Heavy Metals

Heavy metals represent another major category of pollutants. Heavy
metals are present in the earth's crust, and some are needed in trace
amounts to support life processes. Heavy metals can become concentrated
in soils and water by agricultural and other activities to the extent
they become toxic to organisms. Some of the common heavy metals and
trace elements of concern include: aluminum, boron, copper, selenium,
lead, mercury, nickel, zinc, arsenic, chromium, cadmium, and molybdenum.

Heavy metals and trace elements can accumulate from atmospheric
deposition or as a result of pesticide residues, industrial or municipal
wastes, and from leaching of metal-bearing soils or geologic formations.
Application of municipal and food-processing wastes to agricultural land
creates the greatest potential for heavy metal concentrations.

Quality criteria can only be considered met if heavy metals reaching
groundwater or surface water do not exceed allowable standards. The New
Mexico Environment Department should be consulted for most current
information and worksheets available concerning biosolid applications.
NRCS should not take the lead in developing a biosolids management plan.
An RMS may include a biosolids-based nutrient management component if
the client has an NMED-approved plan. All biosolid applications fall
under the U.S. Code, 40 CFR, Parts 403 and 503, General pretreatment
regulations for existing and new sources of pollution and Standards for
the Use or Disposal of Sewage Sludge. The management plan should
address:

-   biosolid composition

-   site and soil condition

-   protection of ground and surface water and wells

-   crop rotations or vegetation

-   biosolid application rates

-   timing of biosolid application

-   application methods

-   public notification

-   odor management

-   required monitoring

## Suspended Sediments and Turbidity

Sediment is organic or inorganic material that is in suspension, in
transport, or already moved and deposited away from its point of origin.
Sediment is considered a pollutant when it concentrates to the point to
which it degrades habitat suitability for aquatic organisms, and/or
increases turbidity that in turn reduces light penetration and the
process of photosynthesis. Turbidity is an expression of the clarity of
water. Turbidity in water results from suspended matter such as clay,
silt, colloidal materials, organic matter, or other material that is
dissolved or suspended in surface water. Suspended sediment and
turbidity are not interchangeable measurements; however, they are
different measures of similar processes and have similar effects on the
environment. Besides interfering with aquatic life, sediment deposition
in water bodies causes reduced water storage capacity, safety hazards
for swimming and boating, increased costs for water treatment, and
reduced aesthetics.

Sediment is the result of erosion, and suspended sediment is the primary
cause of increased turbidity in agricultural streams. Chemicals such as
some pesticides, phosphorus, and ammonium are transported with sediment
in an adsorbed state. As a result, sediment is a carrier of many other
pollutants to surface waters. Over time, changes to the aquatic
environment can cause these chemicals to be released from the sediment
and contribute to eutrophic or toxic conditions.

Availability of sediment from crop and pastureland is best controlled
through erosion control practices. Once soil particles are detached,
practices that reduce water flow so that sediment is deposited on site
before reaching surface waters are preferred. Examples of practices
commonly used to control sediment delivery include residue management,
terraces, contoured strips, filter strips and buffers, grassed
waterways, irrigation water management, sediment control basins, and
tailwater recovery systems.

Other major sources of sediment associated with agriculture stem from
erosion of streambanks, ditches and other drainages. Changes in stream
flow, channel morphology, and vegetative cover represent some of the
contributing factors to bank instability. Grade stabilization
structures, waterways, buffers, permanent vegetative cover, proper
grazing use, bio-engineering practices, etc. are a few of the
conservation practices that might be considered to control streambank
erosion and resultant sediment.

Quality criteria for soil erosion including sheet & rill, wind,
concentrated flow, classic gully streambank, irrigation induced, soil
mass movement, and roadbanks, construction sites, or scour areas should
be met in order to control sediment delivery to water bodies.

Physical measurements of either suspended sediments or turbidity are
possible and relatively inexpensive. Sampling for use as quality
criteria is somewhat problematic. Suspended sediments and turbidity vary
over time and space. Often readings are highest during storm events
increasing with discharge but can vary depending on local turbulence and
velocity. Impacts observed within a given water body may be the result
from sources upstream of the property being evaluated. Water quality
standards for turbidity and suspended solids are usually measured as a
percentage change from baseline conditions. Those baseline conditions
also vary from waterbody to waterbody and from site to site.

Typically, there is a strong relationship between turbidity and
suspended sediment. Generally about 80% of the variability in suspended
sediment concentrations can be explained by simultaneous turbidity
measurements. Turbidity is measured in either Jackson turbidity units
(JTU) or nephelometric turbidity units (NTU). NTU can be measured by
photoelectric turbidimeters that accurately record lower levels of
turbidity and are generally not affected by particle color. Secchi disks
are often used to measure turbidity in lakes.

The planner should use professional judgement along with tools like the
**Water Quality Indicators Guide Field Sheets** to determine if quality
criteria are being met. It is assumed that quality criteria for Soil
Erosion must be met in order to be meeting criteria for sediment.
Physical measurements using secchi disks and inexpensive pocket
turbidimeters over time would add to an individual's professional
judgement.

**Note:** *The planned conservation management system must overcome the
site and management limitations that create excessive sedimentation and
turbidity with practices that control erosion, reduce surface runoff,
and/or filter sediment.*

The water quality criteria for sediment is assumed met by meeting the
quality criteria for erosion. The ***Water Quality Indicators Guide***
provide additional visual descriptors to help indicate a sediment or
turbidity problem. Both waterbodies and farm fields should be evaluated.
When no ditch, stream, lake, pond, or wetland lie in proximity of the
fields being evaluated, the planner must judge likelihood of sediment
laden or turbid runoff reaching off site waters.

## Dissolved Oxygen

Dissolved oxygen (DO) measures the amount of oxygen dissolved in water.
The amount of O~2~ dissolved in water depends upon water temperature,
atmospheric pressure, and the surface area exposed to the atmosphere.
Major oxygen sources include atmospheric oxygen and photosynthesis of
aquatic plants. Oxygen sinks result from respiration and the biochemical
oxygen demand of substances in the water. The capacity of water to hold
oxygen in solution is inversely proportional to the water temperature.
Increased water temperature lowers the concentration of dissolved oxygen
at saturation. Diurnal fluctuations in DO concentrations result from
photosynthesis in excess of respiration as source of oxygen during the
day and at night photosynthesis ceases so respiration acts as an oxygen
sink.

DO concentrations also can vary between the surface stream water and
water flowing through alluvial material in the streambed. Oxygen
replenishment to these intergravel waters comes primarily from the
exchange of well-aerated surface waters with oxygen impoverished
intergravel waters. Low dissolved oxygen within the alluvial materials
in the stream bed affects the survival of fish eggs and invertebrates.
Clogging of gravel with fine sediment and organic matter is the primary
concern affecting this exchange.

Dissolved oxygen is critical to the biological community and for the
breakdown of organic matter. In fact, DO, at appropriate concentrations,
is essential not only to keeping aquatic organisms alive, but also for
sustaining their reproduction, vigor and development. Varying the level
of biological diversity in an aquatic community, such as fish,
invertebrates, algae, and bacteria requires different levels of DO for
successful existence. New Mexico water quality standards for dissolved
oxygen vary depending on temperature, elevation, and the designated use
(State of New Mexico Standards for Interstate and Intrastate Surface
Waters, Jan. 2000).

Oxygen depletion in streams and lakes is usually associated with
excessive temperature, heavy growth of aquatic plants, algal blooms, or
high concentrations of organic matter and nutrients. Practices that
control excess delivery of sediment, nutrients and organics to surface
waters, maintain or lower water temperature, and provide good reaeration
and habitat are most effective in maintaining dissolved oxygen levels.

The quality criteria for nutrients, sediment and turbidity, and aquatic
habitat and temperature should be used to indicate whether suitable
dissolved oxygen levels exist for the benchmark conditions and/or the
planned conservation management system. Direct measurement of dissolved
oxygen levels with inexpensive test kits may also be used as an
indicator if precautions are taken for seasonal and diurnal variability.
Measurement of dissolved oxygen levels would be most appropriate in
water bodies fully contained within the conservation management unit.
Offsite, cumulative effects in flowing waters and larger water bodies
make it difficult to estimate the impacts to dissolved oxygen levels
from land management activities from one farm or management unit.

## Aquatic Habitat & Temperature

Aquatic habitat is included as a water quality parameter because its
suitability directly influences a water body's ability to support
aquatic life. Water temperature is included in this category. Riparian
habitat with sufficient shade and streams with adequate width/depth
ratios are the primary factors affecting temperature. The principal
source of heat energy delivered to the water column is solar energy
striking the water body. When shaded, far less energy will be imparted
to the water body. Shallow, wide streams provide more unit area for
solar heating as well as greater opportunity to transfer heat to the
stream bed, itself. Hydro-geomorphic conditions that impact channel
configuration and stream flow are other factors affecting the
suitability of aquatic habitat and water temperatures.

Measurement of water temperatures would be appropriate in water bodies
fully contained within the conservation management unit taking care to
consider seasonal and diurnal affects. Offsite, cumulative effects in
flowing waters and larger water bodies make it difficult to estimate the
impacts from land management activities from one farm or management unit
on water temperatures.

**Note:** *The planned conservation management system must overcome the
site and management limitations that negatively impact aquatic habitat
and temperature. This includes practices to restore riparian vegetation,
instream habitat, base flow, shade, and hydro-geomorphic functions.*

**[Petroleum Products]{.underline}**

Above ground and underground storage of liquid petroleum products such
as motor fuel and heating fuel presents a threat to public health and
the environment. Petroleum fuels contain a number of potentially toxic
compounds including common solvents such as benzene, toluene, and
xylene, and additives such as ethylene dibromide and organic lead
compounds. Benzene is considered a human carcinogen. Oils affect aquatic
organisms by acting on epithelial surfaces of gills interfering with
respiration. Oil is detrimental to waterfowl by destroying the natural
buoyancy and insulation of their feathers. Several important
petrochemicals are known to be acutely toxic to fish. At low levels,
smell or taste cannot detect fuel contaminants, yet waters may be
contaminated to the point of affecting human health or the environment.

On farm, improper storage and handling of petroleum products are the
most likely sources of potential contaminants. According to the U.S.
Environmental Protection Agency, nearly one out of four underground
storage tanks in the U.S. may now be leaking. In New Mexico, there are
an estimated 4,252 underground storage tanks. NMED is currently aware of
2,216 past and current cases of soil contamination. Approximately 39
public wells, 47 private and 150 water supply wells have been
contaminated or threatened by leaking underground storage tanks.

***The Petroleum Storage and Handling Worksheet*** (Appendix B) may be
used to indicate if benchmark conditions and the planned conservation
management system meet RMS quality criteria. To meet quality criteria, a
ranking of low or low-moderate risk must be obtained.
