Collection and Control of Evidence
Information and evidence should be collected using procedures
intended to recognize property and privacy rights.
Following proper procedures reduces the possibility that
evidence tending to show a party's guilt will be excluded from
use in Water Quality enforcement hearings or if the enforcement
case is brought before a court.
Collecting detailed evidence of each investigation will assist in
preparing notices, determining the appropriate enforcement
response, and recounting details of the investigation during
enforcement meetings.
Be clear, objective and informative when writing details and
findings of an investigation.
• All physical evidence (notes, forms, and photos) and other
documentation should be stored in an individual investigation folder
and placed in the appropriate document storage file cabinet on the 3rd
Floor of City Hall.
• Additionally, electronic records in the WQ Investigations Access
Database can only be edited and accessed by staff members in the
WQ Section.
• This level of security ensures that evidence supporting on -going cases
is not compromised.
Photographic Evidence

party information posted on signs or vehicles
Take photos that will show detail and also take photos

Field Measurements
Some investigations require only direct visual observations, such as illicit
vehicle washing activities, while others require field testing to confirm a
violation has occurred.
It is important to be prepared for identifying, documenting, and tracking down
a potential pollution source before an investigator leaves to conduct an
investigation.
An investigator must use their judgment to decide what equipment or
information might be needed to conduct an investigation which may include
sampling equipment, tracing dyes, water chemistry meters, maps, safety vests,
and tools.
wQ investigators typically use the following for field measurements:
field sampling equipment - sampling poles and peristaltic pumps
indicator test kits - Chemetrics suite of parameters include ammonia,
chlorine, detergents, copper, and phenols
other water quality testing instruments to measure for indications of
potential pollution - YSI multi -parameter meters, Hach turbidimeters and
chlorine meters
Collecting Samples & Chain -of -custody
Occasionally, water samples need to be taken to confirm and quantify specific
pollutants that field equipment is not able to detect.
Once the sample is taken, it should be stored according to the sampling
requirements used for the ambient monitoring program or proper sample
handling procedures if sampling for an atypical parameter. Sampling
requirements for the ambient monitoring program can be found in the
document, 'Ambient Water Chemistry Monitoring Program QAPP."
Investigators must schedule a pick-up of samples with the City's contract
laboratory ENCO Laboratories, Inc. in Cary, NC.
The lab must be notified before the sample is taken to ensure they are able to
analyze it within the proper hold time.
A properly filled out chain -of -custody form should accompany the sample with
a specific sample name (typically, the WQ investigation #), the number of
bottles and the requested analysis.
