Water Quality Data Acquisition Sources
I was wondering what sources are available, or if anyone has water quality data for the Great Lakes and specifically Lake Ontario?
We are interested in mapping Phosphorus, Organic Matter, Nitrogen and Dissolved Oxygen concentrations in Lake Ontario as they relate to algal blooms and hypoxia.
You could check EPA's WATERS program:
USGS also has a water monitoring program.
Water is one of BC&rsquos most important natural resources and must be managed appropriately to protect both human and ecosystem health.
Drinking Water Quality
Clean and safe water for drinking is essential to maintain our health and well-being.
Water quality guidelines are benchmarks for water quality parameters to protect drinking water sources.
Community watersheds are designated areas that require special management practices to reduce the impacts of forest, range, and oil and gas activities on drinking water sources.
Recreational Water Quality
Recreational water provides opportunities for exercise, play and relaxation.
Water quality guidelines are benchmarks for water quality parameters to protect water used for recreation.
Water Quality Guidelines for Aquatic Life, Wildlife & Agriculture

Water Quality Objectives
To manage fresh and marine water quality, water quality objectives may be developed for specific water bodies to protect water values in that watershed.
Water Quality Monitoring
Water quality monitoring of ambient fresh and marine waters is conducted to assess and monitor water bodies in BC.
Understanding Big Data In The Water Industry
If you feel like you have too much data but not enough understandable or usable information, fine-tuning data collection and funneling it into an integrated data management system may be the way to become more proactive and make better decisions.
At a very basic level, Big Data just means we have a lot of data. Water utilities see data from supervisory control and data acquisition (SCADA) systems, including flow statistics, online monitoring, dissolved oxygen (DO) measurements, and air flows, as well as data from laboratory information management systems (LIMS) and computerized maintenance management systems (CMMS), to name several examples.
Such data is beneficial, and much of it has been around for years. Unfortunately, the way data is gathered at treatment facilities is often fragmented. There are silos of data in computer systems that don&rsquot always talk to each other. The Internet Age has ushered in the ability to funnel disparate data into a single, meaningful pool of information that allows water and wastewater treatment plant operators to understand, manage, and use it to optimize plant reliability and performance. Big Data initiatives and new data management tools enable us to turn all that data into understandable, useful information that helps us become more proactive and make better decisions about plant operations.
For example, Black & Veatch offers ASSET360&trade, a smart analytics platform to give utilities, cities, and other entities a holistic, 360-degree understanding of their infrastructure-based systems. Although the focus on Big Data in the water industry is relatively new, comprehensive data management isn&rsquot new for energy utilities Black & Veatch has provided asset analytic solutions to utility clients for more than 20 years and has operated a smart analytics monitoring and diagnostics service for more than 10 years. The company&rsquos utility analytics include operational intelligence and adaptive planning solutions.
Sometimes You Have To Get MAD To Be Smart
No matter what specific services or tools water and wastewater utilities choose to use, it&rsquos important to develop a management plan, pull all important data together, and take advantage of dashboards and smart screens that use that data to perform calculations and identify trends. Then, utility managers can break the information down to answer questions such as &ldquoWhere am I using energy or spending my dollars?&rdquo or &ldquoWhat am I spending on energy and chemicals in different parts of the facility?&rdquo
Furthermore, utility staff with such information in hand can proactively identify potential problems before they happen rather than react to something such as a broken pump. Although SCADA systems have real-time capabilities, displaying current status and immediately warning of problems, being able to predict a potential problem through use of smart analytic platforms is a game changer. The next step &mdash pooling data and using analytical tools to predict where we should be heading to become more proactive &mdash is a big one for the water industry. We&rsquore getting smarter all the time.
Becoming smarter, however, requires focus on the quality as well as the quantity of our data, shifting our focus from Big Data to bad data. If sensors are not cleaned, calibrated, or properly used, for example, it doesn&rsquot matter what we do with the resulting data. The starting point is to make sure you have good primary measurements.
In Smart Water Utilities: Complexity Made Simple (IWA Publishing, 2016), Dr. Pernille Ingildsen and Dr. Gustaf Olsson consider what utilities need to do to be smart. They boil it down to a simple, yet very useful, framework and suggest that water utilities have to be &ldquoMAD&rdquo to be smart.
As they explain, M is for MEASURE, because we have to focus on having good measurements in the right place A is for ANALYTICS, because we have to understand and analyze the data we collect and D pertains to the DECISION-making process. Using what we know to make good decisions can be an automated process in some cases. It can be helpful to split Big Data into these three parts.
In terms of accuracy, the instrumentation that we have now is better than ever, whereas sensors were a weak point in the past. People generally understand the need to clean and calibrate instruments, but it can still be an important starting point.
Improved analytics are more the focus today, with the benefits and needs explained above.
Decisions will be the next focus, and fairly soon, as evidenced by research now underway.
Smart analytics &mdash called Smart Integrated Infrastructure (SII) at my company &mdash have been applied to power stations for many years. In SII, a driving question is &ldquoHow efficient is the plant as a whole?&rdquo With the ability to zoom in on specific pieces and ask questions such as &ldquoHow many dollars per hour does it cost us not to have this part of the plant operating as well as it could?&rdquo utilities and cities can use smart analytics to make smarter decisions by proactively identifying and prioritizing improvements.
Black & Veatch has developed tools specifically for combined heat and power (CHP), membranes, and activated sludge. We are working with the city of Lawrence, KS, to refine tools to enable the city&rsquos plant managers to optimize operations. Initially these tools will be used at the wastewater treatment plant, but eventually they will also be extended to the city&rsquos water treatment facility. Plant operators are already seeing the benefit of being able to visualize information by pulling all operations data together in a consolidated database.
In Lawrence, KS, where the Black & Veatch ASSET360 system is used to track operating costs, data shows the impacts of wet-weather events on treatment costs. The total cost per 1,000 gallons is shown in purple, the secondary treatment flow rate is shown in blue, and the flow rate to the Actiflo system is shown in green. There is a jump in treatment costs during a storm event due to the extra costs associated with operating the Actiflo process.
Big Data Basics
Despite the current focus for many on improving analytics and/ or decisions, there&rsquos also a lot to be said for making sure our foundations are sound. Below are five keys to making Big Data work and avoiding the pitfalls of bad data.
Focus on data quality rather than quantity. Not even the most sophisticated analytics can overcome measurement errors, whether that&rsquos noise, drift, or interferences. If you aren&rsquot confident in your primary sensors and analyzers, you could have a lot of bad data that is worthless, no matter what you do with it. For example, a Water Environment Research Foundation (now the Water Environment & Reuse Foundation) decision support system (DSS) project required a research team member to perform data analytics to pick out anomalies that might indicate toxins in plant influent, but distinguishing anomalies due to toxins from anomalies due to measurement problems proved to be a major hurdle.
Confidence in sensors and analyzers can be gained by:
- Cleaning them. Wastewater treatment is an especially fouling environment and not the best place to put scientific equipment. Operators frequently underestimate how quickly sensors become fouled. Go for autocleaning whenever possible and avoid installing anything in raw sewage or primary effluent unless you really need the measurement because both areas are particularly prone to fouling. Mixed liquor is an easier place to take measurements, and final effluent is the easiest place of all. Water treatment systems usually are less fouling, but sensors still need periodic cleaning.
- Calibrating them.This is generally understood, although the frequency of calibration, particularly for sensors that tend to drift, typically is shorter than ideal.
- Validating them.This may be the action overlooked by most instrumentation suppliers. Analytics to validate the measurements, particularly during calibration, frequently need more attention.
Modern instruments are more reliable than they were in the past, but they still need to be cleaned and taken care of.
Measure only what&rsquos useful to you. What will you actually use to best manage the plant? Some treatment plants lack important and basic measurements (e.g., DO in the aeration basins, airflow to each aeration zone, and electricity use by blowers), but we need to be careful in our enthusiasm not to swing to the other extreme and take measurements that are not especially useful. You can spend serious money measuring ammonia and nitrate all over a treatment plant, but unless you&rsquore actually using it for control, the measurements will eventually be ignored and the instruments neglected. It&rsquos best to have a handful of good instruments, positioned in locations where you&rsquore actually measuring something you can control, and to try to keep those sensors running well.
Think dynamics, not steady state. A lot of the design and operational guidance in textbooks and training materials has simple equations into which you plug a single number to get your answer (e.g., sludge age calculation or removal efficiency). Similarly, influent and effluent samples are usually flow-weighted or time-averaged composites. We&rsquore used to thinking and talking about average daily conditions. However, the reality is that our treatment plants see significant daily variations in flows and concentrations, and therefore we need to look at them as dynamic systems. For example, an online phosphate analyzer taking measurements at the end of the aeration basin just prior to the clarifiers might reveal daily phosphate peaks of 1 or 2 mg/L every afternoon for just an hour or so, but the effluent composite sample measurements could be consistently below 0.2 mg/L. To understand our treatment systems, we need to measure and analyze their dynamics.
Recognize different timescales. Hand in hand with dynamics is the need to think about different timescales: diurnal (daily) variations, weekly trends (especially weekend versus weekday differences), and seasonal shifts. For each of these, the data analytics needs are quite different and need to be carefully considered. For diurnal variations it can be useful to compare one day to the next by overlaying the dynamic data. For weekly trends we can do something similar over a sevenday horizon. And for seasonal shifts it is often beneficial to plot and compare long-term trends to temperature and maybe rainfall shifts.
Tools such as Black & Veatch&rsquos ASSET360 system help water utility managers follow in the footsteps of their energy utility colleagues to harness data for improved decisions and operations.
Consider how to handle outliers and extraordinary events. In data analytics it&rsquos common practice to identify and eliminate outliers, assuming they&rsquore either bad measurements or not typical and therefore something to ignore. But experience shows that a lot of what is done at water and wastewater treatment plants is trying to keep the process stable in response to abnormal events, such as upsets from shock loads or toxins, or, more typically, responding to wet weather for wastewater plants or major line breaks or droughts for water treatment. We need to identify outliers, but rather than throw them away, we need to decide how to respond.
In a nutshell, Big Data is about taking all the data we now have at our fingertips and turning it into knowledge that we can apply to operate our treatment facilities better. The right data, analytics, and decision framework can drive water (and energy) utilities to optimal performance.

Public drinking water source area mapping tool
Use the Public drinking water source areas (PDWSA) online mapping tool to find out if you are living, working or recreating in a drinking water catchment.
The mapping tool will show you if your home, development, project or activity is in a public drinking water source area. Once you know this, you can help us avoid, minimise or manage water quality and public health contamination risks.
It will also show you the public drinking water source areas within a 5-kilometre radius of your location. It displays the priority areas (P1, P2 and P3) that are defined to guide land use planning.
For more information about priority areas, and for a list of land uses and activities that are appropriate within them:
The mapping tool displays special areas called protection zones, which protect the immediate area around where drinking water is abstracted. These are called reservoir protection zones (when they surround a dam or reservoir) or wellhead protection zones (when they surround a bore).
We determine the boundaries, priority areas and protection zones for each public drinking water source area in a drinking water source protection report. These reports provide specific information about each public drinking water source area you see on the map. You can find these reports via the &lsquosearch publication&rsquo function on our website.
Protecting drinking water
Protecting drinking water for current and future generations is a shared responsibility. Safe, reliable and good quality drinking water is important for all Western Australians, because it supports our lives, culture, homes, recreation, environment, development, agriculture and mining.
Drinking water for our cities and towns comes from public drinking water source areas. Public drinking water source areas can be surface or groundwater sources. Surface water sources are the catchments that feed dams and reservoirs, and groundwater sources are underground aquifers that feed bores.

The State of Michigan remains committed to supporting the City of Flint as it continues to recover and rebuild. The state provided more than $350 million to Flint, in addition to the $100 million from the federal government - all of which is helping with water quality improvements, pipe replacement, healthcare, food resources, educational resources, job training and creation, and more.
Flint Water Quality Update
For more than three years in a row Flint's water has been meeting federal standards. The water is now testing at 6 parts per billion (ppb) which is much lower than the federal requirement of 15 ppb. Flint's water is one of the most monitored and testing the same as similar cities across the state and country.
Will filters and water test kits continue to be available?
Yes. The state will continue to provide free water filters, replacement cartridges, and water testing kits until service line replacement is completed. Filters will continue to be available for residents who feel more comfortable using a filter until their confidence in the water quality can be re-established. Filters and residential sampling kits are available at City Hall.
In an ongoing effort to understand the connections between water resources, water systems, and international security and conflict, the Pacific Institute initiated a project in the late 1980s to track and categorize events related to water and conflict, which has been continuously updated since. The database, updated in October 2019, presents the information as a chronology and map. Use the links below to explore the chronological list of events or the interactive events map.
View the Water Conflict Chronology
Basis for Including an Event
Items are included when there is violence (injuries or deaths) or threats of violence (including verbal threats, military maneuvers, and shows of force). We do not include instances of unintentional or incidental adverse impacts on populations or communities that occur associated with water management decisions, such as populations displaced by dam construction or impacts of extreme events such as flooding or droughts. (Based on this new definition, some previous entries were removed in May 2018.)
Form of Conflict
Events are categorized based on the use, impact, or effect that water had within the conflict.
Trigger: Water as a trigger or root cause of conflict, where there is a dispute over the control of water or water systems or where economic or physical access to water, or scarcity of water, triggers violence.
Weapon: Water as a weapon of conflict, where water resources, or water systems themselves, are used as a tool or weapon in a violent conflict.
Casualty: Water resources or water systems as a casualty of conflict, where water resources, or water systems, are intentional or incidental casualties or targets of violence.

Interfor Continues to Grow with Acquisition of Four US Sawmills from Georgia-Pacific
BURNABY, British Columbia, May 27, 2021 (GLOBE NEWSWIRE) -- INTERFOR CORPORATION (“Interfor” or the “Company”) (TSX: IFP) announced today that it has reached an agreement with Georgia-Pacific Wood Products LLC and GP Wood Products LLC (collectively “Georgia-Pacific”) to acquire four of its sawmill operations located in Bay Springs, MS, Fayette, AL, DeQuincy, LA and Philomath, OR (collectively the “Sawmill Operations”). The total purchase price of US$375 MM, which includes working capital, will be funded entirely from cash on hand.
The Sawmill Operations are highly complementary to Interfor’s existing platforms in the US South and the US Northwest, and the acquisition will support accelerated growth and enhance the Company’s position to benefit from robust market conditions. The acquisition will be immediately accretive to Interfor’s earnings and is expected to provide attractive returns in both the near-term and over the long-term.
“This acquisition enhances Interfor’s growth-focused strategy as a pure-play lumber producer, and provides significant economies of scale given the complementary geographic fit with our existing US operations” said Ian Fillinger, President and Chief Executive Officer. “We’re excited to acquire these high-quality assets as part of our balanced approach to capital allocation to drive shareholder value.”
The Sawmill Operations have a combined annual lumber production capacity of 720 million board feet. The Bay Springs, Fayette and Philomath sawmills are currently operating on a full-shifting basis. The DeQuincy sawmill, which was idled in May 2020 during the COVID-19 pandemic, has an annual capacity of 200 million board feet. Interfor is currently evaluating its strategy and options for the site, including re-start plans.
On a pro-forma basis, Interfor’s total annual lumber production capacity will increase to 3.9 billion board feet, of which 3.0 billion board feet or 77% will be US-based and not subject to softwood lumber duties. Interfor’s US South production capacity will grow by 500 million board feet, or 29%, to 2.2 billion, while production capacity in the US Northwest will grow by 220 million, or 40%, to 770 million board feet. Following the transaction, 57% of Interfor’s production capacity will be in the US South, 20% will be in the US Northwest and the remaining 23% will be in British Columbia.
The Sawmill Operations, excluding the DeQuincy sawmill, generated US$53 million of EBITDA 1 in the first quarter of 2021, reflecting an EBITDA 1 margin of US$508 or $643 per thousand board feet. This compares favorably with Interfor’s EBITDA margin of $589 per thousand board feet for the same period.
Following the completion of this transaction Interfor will continue to have significant financial flexibility to consider additional value-creating capital deployment options. As of April 30, 2021 Interfor was in a net cash position of approximately $380 million. Proforma this acquisition and the special dividend announced on May 12, 2021, Interfor’s Net Debt to Invested Capital ratio as of April 30, 2021 would increase to 13%. Similarly, proforma liquidity as of April 30, 2021 would be approximately $500 million, before consideration of significant additional borrowing capacity available under existing credit limits and continued strong near-term operating cash flows.
The completion of the acquisition is subject to customary conditions and regulatory approvals for a transaction of this kind and is expected to close in the third quarter of 2021.
1 Reflects mill level EBITDA as prepared in accordance with Georgia-Pacific’s financial practices.
