Water Quality Assessment

Groundwater quality problems can include naturally-occurring contaminants, such as arsenic, uranium, radon, fluoride, iron and manganese staining, hardness, sea water intrusion, iron bacteria, acidity and corrosion, and silt, turbidity and odor problems. Man-made groundwater problems can include: road salt, petroleum hydrocarbons, septic effluent, nitrate, pesticide, and hazardous materials such as PCB, dry cleaning chemicals, pathogens and heavy metals. Evaluation of surfaced groundwater quality is provided by our team, as well as a full range of services for the investigation, sampling, analysis, and interpretation of water quality problems to domestic, commercial, institutional and municipal well users.

Noise Evaluation and Management

The impact of noise on residential and environmentally sensitive areas has become a standard part of environmental impact assessments and permitting for many proposed developments and projects. Ontario Environmental & Safety Network Ltd.. provides services in occupational and environmental noise impact assessments that involve the evaluation of the impacts of a variety of sources on both residential and commercial areas. Noise control within plants for worker hearing protection is also an active part of Ontario Environmental & Safety Network Ltd..'s noise management practice.

Ontario Environmental & Safety Network Ltd.. is equipped with state-of-the-art, well maintained sound level metres. Our staff is fully trained on their use as well as data interpretation. In addition, Ontario Environmental & Safety Network Ltd.. has the latest computer modeling tools to evaluate various noise scenarios (i.e., noise from road traffic, railways, aircraft, construction, landfills, quarries, or other industrial facilities). These models permit an easy, rapid evaluation of various mitigative measures and operational options to evaluate the best means of obtaining compliance with regulatory requirements.

OESN Ltd. is experienced in providing noise impact assessments. Clients range from developers requiring noise impact assessments for sensitive land uses to industries evaluating their noise impact from stationary sources.

OESN Ltd. can assess day-time and night-time noise levels for outdoor living areas, sleeping quarters, living quarters and plane of bedroom window criteria.

OESN Ltd. will assist our clients, to avoid future problems in a proactive manner through input into the land planning process. OESN Ltd. will represent our clients interests in negotiations with Regional/City planners and MOE noise unit.

Assessment of Noise Impacts

Following Ministry of Environment guidelines, OESN Ltd. will identify potential neighbouring sources. Transportations sources include road, rail and air traffic. Stationary sources encompass sewage treatment facilities, hydro transformer stations, major commercial facilities and industrial processes.

Measurement of Noise Impacts

Leq, Lmin & Lmax levels are measured with a Quest 2900 Sound Level Meter and compared with MOE noise criteria. Ontario Road Noise Analysis Method for Environment & Transportation (ORNAMENT) is used to characterize the noise impacts.

Attenuation If levels do not meet MOE standards, control measures such as acoustical barriers, architectural design, building construction, mitigation at source, site planning or window/doors can be used to reduce noise levels.
